An Analysis Of Eastin s Style Of Writing - 1332 Words

Eastin’s style of writing is very focused on characters and how they interact. Every single one of his characters possesses unique traits and personalities. He somehow manages to create characters that the audience strives to be, and yet they are all pretty normal people. Take Neal Caffrey for example. He is the main character of White Collar and a pretty normal person. He turns from his life of crime and seeks a home, friends, and family (Eastin). The audience wants to be like him not because of the life he was given, but because of the life he creates for himself through hard work and reform. There is rarely a scene focusing solely on one character. The many interactions between characters make the show feel alive and buzzing with†¦show more content†¦Throughout the show, they grow closer and Neal tries to put his life of crime behind him and start a new life in New York with the bureau (Eastin). Throughout the series, Neal betrays Peter’s trust time and time again despite their friendship. Although Neal has good intentions, the audience knows what he is doing is wrong. That doesn’t matter, though, as the audience still finds themselves rooting for Neal. His character has such a unique personality it almost feels real. Neal Caffrey has been sculpted so magnificently that by the end of the show he is like a friend to many viewers. Eastin said the thing that gives Neal his allure is â€Å"They get to where they’re going by sheer force of personality. Neal is someone you could easily hate, but I think Matt Bomer brings so much boyish charm to him that you end up liking the guy despite that.† (Shattuck). In a way, Neal has conned the audience into liking him, but nobody seems to mind. Peter Burke, Eastin’s â€Å"alter ego†, transforms throughout the show, each season growing more compassionate and less strict. Neal convinces him that the way to justice is sometimes blocked by corruption in the FBI and othe r agencies, and they work together to skirt around that corruption and make a difference in the world (Shattuck). The whole idea for White Collar came from a hot tub with Jeff Eastin and his friend, Travis Romero. Eastin wanted to pursue a show about white collar crime because he thought it was â€Å"the one place

Dental Treatment Planning For Patients Using Cannabis

Dental Treatment Planning Considerations in Patients Using Cannabis Sarah E. Grafton1, Alexandre R Vieira2 1. Department of Comprehensive Care, University of Pittsburgh School of Dental Medicine 2. Department of Oral Biology, University of Pittsburgh School of Dental Medicine ABSTRACT Background and Overview. There is a deficit in clinical research on the potential risks involved in treating dental patients using cannabis, either for medicinal or recreational purposes. The aim of this case report is to illustrate the wide variety of available cannabis options and their potential impacts on dental treatment. Case Description. A 27-year-old African American male presented to the dental clinic with nonrestorable molar requiring extraction. During the review of his medical history, the patient reported taking a â€Å"dab† of marijuana approximately five hours prior to his appointment. Due to the admission of recent illicit drug use, no treatment was rendered. The patient was offered an appointment the next day but refused citing the bias in regard to cannabis use. Conclusions and Practical Implications. The number of Americans using marijuana is rising rapidly. Pending legalization in most states will require dentists to address the possible effects of this increase on dental practices. It is imperative dental providers make clinical decisions based upon scientific evidence regarding the pharmacological and psychological effects of cannabis, not on the societal stigma

Writing as an Artist Free Essays

â€Å"Detail makes the difference between boring and terrific writing. It’s the difference between a pencil sketch and a lush oil painting. As a writer, words are your paint. We will write a custom essay sample on Writing as an Artist or any similar topic only for you Order Now Use all the colors.† Rhys Alexander makes an interesting connection between authors and artists in his quote about writing. The idea that writers are indeed artists of a sort, gives us the opportunity to think about how words can become like paint applied to a canvas. The canvas, when one looks further, is actually our reader’s mind. This happens because the reader’s mind becomes the dwelling place where the full color and texture of our written ideas are absorbed and understood. Taking this idea of the artistic endeavors of writing a step further, a writer, like an artist, is most often influenced by the environment around them. Would Monet’s painting of water lilies have turned out so ascetic if the day had been dull and rainy, thus altering his mood to reflect a dull and listless pond? As writers our environment touches on our senses and perceptions, altering our mood and also our writing; thus adding to our strengths and weaknesses, and giving our words the vibrancy and hues we need to paint our â€Å"canvas†. A bedroom is a wonderful safe haven from the chaos of everyday life. In this room we rest, dream and spend time with our own being in simple comfort. These sensations of relaxation and solitude form the basis of why I choose it as my primary writing environment. Here I can mix the ideas, opinions and data I have collected from the outside world and make a work of art that reflects my own inner thoughts of the experiences of which I write about. In my room I can be as creative as I like, without others to criticize or influence my words. Granted, people will do that later once the work is complete; but while it’s being created, it’s completely my own. The comfort of my room strengthens my writing because it adds to my feelings of comfort and security. These perceptions allow me to search deeper and possibly write with more courage about how I feel. If I were to do this anywhere else I would fear that others would judge my words and ideas even before the writing is finished. Then I might not find the nerve to write my own thoughts and opinions, but rather someone else’s. In this sense, solitude and comfort help me paint my verbal canvas with clarity. Solitude and comfort in a bedroom can however be a weakness due to the fact that it at times feels like the â€Å"same old thing† and induces writer’s block. Sometimes the feelings of our surroundings â€Å"lock† us into a repetitive pattern, and soon we find that all of our writings begin to take on similar qualities with no unique flare to make them original. For this problem, sometimes it is best to escape to the outside world and gather more data, or try and capture someone else’s enthusiasm for a topic. When this is not available however, altering a writing environment can help. Open the blinds, let some sunshine in, or maybe even close them and try writing by candle light. These are ways that can improve if not the writing environment itself, at least the writer’s mood. Hanging inspiring paintings or photos on the wall may or turning on music that suits the feelings we are trying to convey may also be helpful. Sometimes writers have to be as creative with their environment as they are with their words. Thus far we have seen that a writer’s environment touches on their senses and perceptions, altering their mood and also their writing; thus adding to their strengths and weaknesses, and giving their words the vibrancy and hues they need to paint their â€Å"canvas†.   I have only minimally explored and shared with you what my environment means to me and how I can improve it if needed. However, I hope that you as the reader have gotten a glimpse of where and why I create my art the way I do. I believe that each of us is inspired by the environment around us, whether it be the crashing of a thunderstorm or the slow steady roll of the ocean waves lulling us to sleep.

Democracy played a vital role in the Philippines. The Americans introduced this kind of government to us when they got our country from the Spaniards 112 years ago. The Philippine Presidents taking oath after the rule of American regime implemented the same form of government until a dictator emerged In the personality of President Ferdinand E. Marcos. President Marcos declared Martial Law on September 23, 1972 by virtue of Proclamation No. 1081 . Marcos, ruling by decree, curtailed press freedom and other civil liberties, closed down Congress and media establishments, and ordered the rrest of opposition leaders and militant activists, including his staunchest critics. senators Benigno Aquino, Jr. ,Jovito Salonga and Jose Diokno. The declaration of exiled in the U. S for three years, the Filipino opposition activist Benigno Aquino was assassinated on the tarmac of Manila airport on 21 August 1983, moments after his return to the country to challenge the rule of long-term president, Ferdinand Marcos. That was also the day Maria Corazon Sumulong CoJuangco-Aquino stopped being, in her words, Just a housewife. Before we go further, lets know more about Ninoys Wife first. Corazon CoJuangco was born the sixth of eight children in Tarlac, a member of one of the richest Chinese-mestizo families in the Philippines. She was born to Jose CoJuangco of Tarlac and Demetria Sumulong of Antipolo, Rizal. Her ancestry was one-eighth Tagalog in maternal side, one-eighth Kapampangan and one-fourth Spanish in her paternal side, and half-Chinese in both maternal and paternal sides. She was sent to St.  Scholasticas College Manila and finished grade school as class valedictorian in 1943. In 1946, she studied high school for one year in Assumption Convent Manila. Later she was sent overseas to study in Ravenhill Academy in Philadelphia, the Notre Dame Convent School in New York, and the College of Mount Saint Vincent, also in New York. She worked as a volunteer in the 1948 United States presidential campaign of Republican Thomas Dewey against President Harry Truman. She studied liberal arts and graduated in 1953 with a Bachelor of Arts in French Language, with a minor in mathematics. She intended to become a math teacher and language interpreter. Aquino returned to the Philippines to study law at the Far Eastern University, owned by the family of the late Nicanor Reyes, Sr. , who had been the father-in-law of her older sister Josephine. She gave up her law studies when in 1954, she married Benigno Servillano Ninoy Aquino, Jr. the son of a former Speaker of the National Assembly. They had five children together: a son, Benigno Simeon Aquino Ill, who was elected as the 1 5th President of the Philippine Republic in May 2010, and four daughters, Maria Elena A.  Cruz, Aurora Corazon A. Abellada, Victoria Eliza A. Dee, and actress-television host Kristina Bernadette A. Yap. Aquino had initial difficulty adjusting to provincial life when she and her husband moved to Concepcion, Tarlac in 1955, after her husband had been lected the towns mayor at the age of 22. The American-educated Aquino found herself bored in Concepcion, and welcomed the opportunity for she and her husband to have dinner inside the American military facility at nearby Clark Field. Benigno Aquino soon emerged as a leading critic of the government of President Ferdinand Marcos of the Nacionalista Party, and there was wide speculation that he would run in the 1973 presidential elections, Marcos then being term limited. However, Marcos declared martial law on September 21, 1972, and later abolished the 1935 Constitution, allowing him to remain in office. Aquinos husband was among those arrested at the onset of martial law, later being sentenced to death. During his incarceration, Aquino drew strength from prayer, attending daily mass and saying three rosaries a day. As a measure of sacrifice, she enjoined her children from attending parties, and herself stopped from going to the beauty salon or buying new clothes, until a priest advised her and her children to instead live as normal lives as possible. In 1980, Aquinos husband was released from Jail in order to undergo heart Harvard University for the next three years. His family lived with him in the Boston rea and his wife described the time as the best years of her life. In 1983 supporters of the anti-Marcos factions persuaded Aquinos husband to return to the Philippines and to lead their cause. When his plane landed on the tarmac of the Manila International Airport on August 21, 1983, Aquinos husband was assassinated. Cory Aquino returned to the Philippines a few days later and led her husbands funeral rites, where more than two million people were estimated to have participated, the biggest ever in Philippine history. From the moment of Ninoy Aquinds assassination, Corazon Aquino became an acclaimed public figure. The shy woman learned to address huge rallies. There was so much rage in her. It did not seem difficult to speak her mind out before thousands of people and to become gadfly her husband had been. She prodded into action against the Marcos government, to demand an honest investigation into her husbands murder. Marcos claimed the assassin was Galman, whom he described as a Communist. Somehow, Galman had slipped through the security cordon with a weapon and shot Aquino before guards killed him. A Marcos-appointed commission came to the same conclusion. More likely, Galman was set up as the fall guy and then killed to ensure is silence. Subsequent investigations revealed that Galman was a petty criminal with links to the police. His family said that days before his death, Galman left his house in the company of several police and soldiers. Public pressure for Justice was strong. General Fabian Ver, Marcoss chief of staff, and twenty-five others were tried for the murder but were acquitted in December 1985. This incident pushed the limit to Mrs. Aquino. After the death of Ninoy, a group later known as the Convenors, held their first meeting in October 1984, at the home of Cory Aquinds mother in the ealthy Dasmarihas Village subdivision in the town of Makati in the metropolitan Manila. The convenors decided that three of their number would screen candidates and would choose one after consultation. The three were Ongpin, Cory Aquino and Lorenzo Tanada, venerable elder statesman of the opposition movement. During the convenors deliberations, Cory Aquino began to emerge as a political force in her own right, no longer simply the widow of Ninoy. At first, her role was to lend moral authority to the convenors, but Tanada and the others, despairing of the alternative, egan to see Aquino as the only candidate capable of uniting the opposition. They needed a candidate with a reputation for personal integrity who could appeal to conservative communists, left-leaning progressives, and the broad masses. They also needed a candidate acceptable to Washington, which exerted broad influence in the Philippines, and which had long supported Marcos of a dearth of alternatives. Aquinds seeming lack of personal ambition and deep-seated ideology made her perfect for the task. l am Just one of the thousands and millions of victims of the Marcos Regime, Cory would tell the crowds who came to hear her speak. am not the victim who has suffered the most, but perhaps the victim who is best known. I look around me and I see a nation that is sinking deeper and deeper into despair. I sense a growing feeling of helplessness and a creeping belief that no matter what abuse may be thrown at our faces, we are powerless to do anything about it. And since the Philippines needed an unequivocal change from the twenty-year rule of him for presidency. More than anyone, Cory Aquino knew the hard work, planning, meetings, and campaigning required. Like Ninoy, she was now away from home and the family for sixteen hours a day. She campaigned like a trouper, answering nasty remarks with simple retorts. To the comment that she had no experience, she replied, It is true that I have no experience in lying, cheating, stealing and killing. I offer you honesty and sincerity in leadership. To the others she promised, if elected, not to live in Malacanang. I will open it up to the people. She spoke before women, peasants, workers, and students as well as upper-class civic groups. To them all, she was a symbol of an uncorrupted woman, a woman they could trust. She made no great promises about immediately solving the staggering problems of the bankrupt country. It seemed enough, at the moment, to topple a brutal dictatorship, to restore civil rights and liberties, to open up democratic space, as she called it. Only with patience, and through peace and reconciliation, would the country be able to move forward. Her popularity reached a high point when one million people showed up at a post-election rally in Luneta Park in Manila on February 16. On February 25, Corazon Aquino was sworn in as the seventh president of the Philippines in a political upset that has been called historic. The New Year began with smiles and accolades. President Aquino, a woman, was honored by Time Magazine as its Man of he Year for 1986. On January 19, she won the Martin Luther King Award for nonviolence. We are finally free, and we can truly be proud of the unprecedented way we achieved our freedom, with courage, with determination, and most important, in peace. A new life starts for our country. But making that new life work was proving extremely difficult, as the woman in charge of what everyone called the Cory government rolled up her sleeves and got down to work. Her first act after taking office was to appoint a presidential cabinet of seventeen advisers. All of them had been opposed to President Marcos. Thirteen of them were lawyers, and five had attended Harvard University or Yale. Whatever their individual differences, the cabinet members got right down to work, too. Their first project was fguring how to run the government without having to abide by the structure set up by Ferdinand Marcos. Intent on upholding civil and human rights, she reestablished the writ of habeas corpus suspended by Marcos in 1971. Once again people were given protection against illegal imprisonment. She removed restraints on freedom of the press and on the rights of labor. Fulfilling a campaign promise, she announced the nconditional release from Jail of some five hundred political prisoners, including communists, an act that drew both applause and criticism. By mid-March, the president created the Committee on Human Rights, abolished the old National Assembly filled with Marcos followers, and adopted a provisional Freedom Constitution. The opening up of democratic space was not only to benefit the people but necessary for the president herself. She is deeply committed to the democratic process, for through freedom of expression she can hear a broad range of popular opinion.

Biography of Robert Mugabe, President of Zimbabwe

Biography of Robert Mugabe, President of Zimbabwe Robert Mugabe has been the president of Zimbabwe since 1987. He attained his job after leading bloody guerrilla warfare against the white colonial rulers of what was then Rhodesia. Birthdate Feb. 21, 1924, near Kutama, northeast of Salisbury (now Harare, the capital of Zimbabwe), in what was then Rhodesia. Mugabe quipped in 2005 that he would remain president until he was a century old. Personal life Mugabe was married to Ghanian national Sally Hayfron, a teacher and political activist, in 1961. They had one son, Nhamodzenyika, who died during childhood. She died of kidney failure in 1992. In 1996, Mugabe married his onetime secretary, Grace Marufu, who is more than four decades younger than Mugabe, and with whom he had two children while his wife Sallys health was failing. Mugabe and Grace have three children: Bona, Robert Peter Jr., and Bellarmine Chatunga. Political affiliation Mugabe leads the Zimbabwe African National Union – Patriotic Front, a socialist party founded in 1987. Mugabe and his party are also heavily nationalist with left-wing ideology, favoring land seizures from white Zimbabweans while claiming that doing so counters the nations imperialist past. Career Mugabe holds seven degrees from South Africas Fort Hare University. In 1963 he was secretary general of the Maoist Zimbabwe African National Union. In 1964, he was sentenced to 10 years in prison for subversive speech against the Rhodesian government. Once released, he fled to Mozambique to launch a guerrilla war for independence. He returned to Rhodesia 1979 and became prime minister in 1980; the next month, the newly independent country was renamed Zimbabwe. Mugabe assumed the presidency in 1987, with the prime minister role being abolished. Under his rule, annual inflation has soared to 100,000%. Future Mugabe has faced probably the strongest, most organized opposition in the Movement for Democratic Change. He accuses the MDC of being Western-backed, using this as an excuse to persecute MDC members and order the arbitrary arrest of and violence against supporters. Instead of striking terror into the citizenry, this could further galvanize opposition against his iron-fisted rule. Action from neighboring South Africa, deluged by Zimbabwean refugees, or world bodies could also pressure Mugabe, who relies on the war veterans militia to help him keep his grip on power. Quote Our party must continue to strike fear in the heart of the white man, our real enemy! - Mugabe in the Irish Times, Dec. 15, 2000

Biography of Humphry Davy, Prominent English Chemist

Biography of Humphry Davy, Prominent English Chemist Sir Humphry Davy (December 17, 1778–May 29, 1829) was a British chemist and inventor who was best known for his contributions to the discoveries of chlorine, iodine, and many other chemical substances. He also invented the Davy lamp, a lighting device that greatly improved safety for coal miners, and the carbon arc, an early version of the electric light. Fast Facts: Sir Humphry Davy Known For: Scientific discoveries and inventionsBorn: December 17, 1778 in  Penzance,  Cornwall, EnglandParents: Robert Davy, Grace Millet DavyDied: May 29, 1829 in Geneva, SwitzerlandPublished Works: Researches, Chemical and Philosophical, Elements of Chemical PhilosophyAwards and Honors: Knight and baronetSpouse: Jane ApreeceNotable Quote: Nothing is so dangerous to the progress of the human mind than to assume that our views of science are ultimate, that there are no mysteries in nature, that our triumphs are complete and that there are no new worlds to conquer. Early Life Humphry Davy was born on December 17, 1778, in  Penzance,  Cornwall, England. He was the eldest of five children of parents who owned a small, less-than-prosperous farm. His father Robert Davy was also a woodcarver. Young Davy was educated locally and was described as an exuberant, affectionate, popular boy, intelligent and having a lively imagination. He was fond of writing poems, sketching, making fireworks, fishing, shooting, and collecting minerals; he was said to wander with one of his pockets filled with fishing tackle and the other overflowing with mineral specimens. His father died in 1794, leaving his wife, Grace Millet Davy, and the rest of the family heavily in debt because of his failed mining investments. The death of his father changed Davy’s life, making him determined to help his mother by quickly making something of himself.  Davy was apprenticed to a surgeon and apothecary a year later, and he hoped eventually to qualify for a medical career, but he also educated himself in other subjects, including theology, philosophy, languages, and the sciences, including chemistry. About this time he also met Gregory Watt, son of the famous Scottish inventor James Watt, and Davies Gilbert, who allowed Davy to use a library and chemical laboratory. Davy began his own experiments, mainly with gases. Early Career Davy began preparing (and inhaling) nitrous oxide, known as laughing gas, and carried out a series of experiments that almost killed him and may have damaged his long-term health. He recommended that the gas be used as anesthesia for surgical procedures, though it was half a century later before nitrous oxide would be used to save lives. An article Davy wrote on heat and light impressed Dr. Thomas Beddoes, an eminent English physician and scientific writer who had founded the Pneumatic Institution in Bristol, where he experimented with the use of gases in medical treatment. Davy joined Beddoes institution in 1798, and at age 19 he became its chemical superintendent. While there he explored oxides, nitrogen, and ammonia. He published his findings in the 1800 book Researches, Chemical and Philosophical, which attracted recognition in the field. In 1801, Davy was appointed to the Royal Institution in London, first as a lecturer and then as a professor of chemistry. His lectures became so popular that admirers would line up for blocks to attend them. He had earned a professorship five years after reading his first chemistry book. Later Career Davy’s attention turned to electrochemistry, which became possible in 1800 with Alessandro Voltas invention of the voltaic pile, the first electric battery. He concluded that the production of electricity in simple  electrolytic cells  resulted from chemical action between substances of opposite charges. He reasoned that  electrolysis, or the interaction of electric currents with chemical compounds, offered a way to decompose substances to their elements for further study. In addition to using electrical power to conduct experiments and isolate elements, Davy invented the carbon arc, an early version of the electric light that produced light in the arc between two carbon rods. It didnt become economically practical until the cost of producing the power supply became reasonable years later. His work led to discoveries regarding sodium and potassium and the discovery of boron. He also figured out why chlorine serves as a bleaching agent. Davy did research for the Society for Preventing Accidents in Coal Mines, leading to his 1815 invention of a lamp that was safe to use in mines. Named the Davy lamp in his honor, it consisted of a wick lamp whose flame was enclosed by a mesh screen. The screen allowed for the mining of deep coal seams despite the presence of methane and other flammable gases by dissipating the flames heat and inhibiting ignition of  the gases. Later Life and Death Davy was knighted in 1812 and was made a baronet in 1818 for contributions to his country and to mankind; especially the Davy lamp. In between, he married rich widow and socialite Jane Apreece. He became president of the Royal Society of London in 1820 and was a founding Fellow of the Zoological Society of London in 1826. Beginning in 1827, his health began to decline. Davy died at Geneva, Switzerland, on May 29, 1829, at age 50. Legacy In Davys honor, the Royal Society has awarded the Davy Medal annually since 1877 â€Å"for an outstandingly important recent discovery in any branch of chemistry.† Davys work served as a guide and inspiration encouraging many to study chemistry, physics and other fields of science, including Michael Faraday, his lab assistant. Faraday became famous in his own right for his contributions to the study of electromagnetism and electrochemistry. It has been said that Faraday was Davys greatest discovery. He also was known as one of the greatest exponents of the  scientific method, a mathematical and experimental technique employed in the  sciences, specifically in the construction and testing of a  scientific hypothesis.
