Research paper - Essay Example There are two ways to classify fuels. Firstly, on the basis of the physical state they exist in, either being solid, liquid or gas and secondly, how they are obtained: either naturally or are manufactured. Fuels existing naturally include Wood, Coal, Petroleum and Natural gas whereas manufactured fuels include Coke, Charcoal, Alcohols and Water gas to name a few (Types of Fuels and Their Characteristics 37-38). Solid fuels for example Coal have been widely used throughout and have a number of advantages. Their transportation is easy and also there is no risk of a spontaneous explosion. They also do not possess a very high temperature for ignition. However, their content of ash is great which is harmful for the environment (Types of Fuels and Their Characteristics 38). Around 80% of the coal is used for generating electricity. It is also utilized in furnaces for steel production. The refined coal is called ‘coke’ and it does not pollute the environment. When coal is heated in the absence of the air, coal tar and coal gas are removed which are its impurities (Walker 11). Out of all the fossil fuels, coal has the highest number of reserves around the world and is obtained through mining. Huge number of ‘coal basins’ are present in the Northern hemisphere of the Earth, like in the countries England, China and Australia to be specific (Spliethoff 25). The liquid fuels like Petroleum can be classified as natural or crude oils and also as manufactured or artificial oils. The advantages of liquid fuels include easy storage and transport, requirement of less space and no production of dust or ash upon heating. On the other hand their use carries some disadvantages as well. They give off a bad odor, special tanks are required for their transportation and the extremely inflammable and volatile nature of these liquids pose great hazards (Types of Fuels and Their Characteristics

Phase Contrast Imaging Thesis Example | Topics and Well Written Essays - 3750 words

Phase Contrast Imaging - Thesis Example The traditional approach is reliant on X-ray absorption as a mere source of contrast, and also outlines chiefly on ray optics to define and interpret the formation of image. As suggested by Yacobi et al, Phase contrast is the most challenging and complicated mechanism for a beginner to imagine, however, at the same time, it is the most powerful mechanism for generating images with ultra-high resolution (Yacobi et al, 1994). Phase Contrast imaging, which is informally known as High Resolution or HR imaging, is a process of imaging in Transmission Electron Microscopy, and is one of the chief components that discriminates Transmission Electron Microscopy from traditional optical microscopy. Nevertheless, phase contrast imaging is often interpreted as synonymous to high-resolution TEM (Williams and Carter, 1996). Moreover, phase contrast microscopy produces high-contrast images of transparent samples such as cells or micro-organisms (Murphy, 2002). This ability commences from the fact that the atoms in a substance disseminate electrons as they pass through them, thereby, giving rise to diffraction in contrast, along with the distinction that is already prese nt in the transmitted beam. Phase-contrast imaging contributes to the maximum imaging technology that has ever developed, and can also enable for resolutions ranging less than one angstrom, thus, allowing the straight viewing of lines of atoms in a crystalline substance. As suggested by Wilkinson and Schut, in phase contrast microscopy, the differences in refractive index are converted into differences in the image intensity (Wilkinson and Schut, 1998). The explanation of phase-contrast images is usually not a clear-cut task by any means. As viewed by Zhang, phase contrast images usually exhibit periodic contrast transformations or reversals (Zhang, 2001). The uncoiling of the differences viewed in the High Resolution image in order to identify the features as a result of which the atoms in the substance can hardly be performed with the naked eye. As an alternative, for the reason that the merger of contrasts as a reason of the multiple diffracting constituents as well as planes and the transmitted beam is diverse, the computer replications are brought in to use so as to identify what kind of distinct disparate structures may create in a phase-contrast image. As a point in fact, a sensible amount of information regarding the sample is required to be comprehended prior to the interpretation of a phase contrast image, for example a speculation about the constituents of the

An analysis of the Feminism Theory

An analysis of the Feminism Theory Belief in the social, political and economic equality of the sexes, the movement organized around this belief. Feminist theory is an outgrowth of the general movement to empower women worldwide. Feminism can be defined as a recognition and critique of male supremacy combined with effort to change it. Simply saying: Feminist fights for the equality of women and argue that women should share equally in societys opportunities and scare resources. Goals of Feminism: To demonstrate the importance of women. To reveal that historically women have been subordinate to men. To bring about gender equity. Historical Perspective: Three Waves of Feminism First Wave (19th through early 20th centuries). Second Wave (1960s-1980s). Third Wave (1990s-Present) First Wave Feminism: First-wave feminism refers to a period of feminist activity during the nineteenth century and early twentieth century. It focused primarily on gaining the right of womens suffrage. The term, first-wave, was coined retrospectively after the term second-wave feminism began to be used to describe a newer feminist movement that focused as much on fighting social and cultural inequalities as further political inequalities. Second Wave Feminism: The second-wave of the Womens Movement began during the early 1960s and lasted throughout the late 1970s. Whereas first-wave feminism focused mainly on overturning legal (de jure) obstacles to equality (i.e. voting rights, property rights), second-wave feminism addressed a wide range of issues, including unofficial (de facto) inequalities, official legal inequalities, sexuality, family, the workplace, and, perhaps most controversially, reproductive rights. Third Wave Feminism: Third-wave feminism began in the early 1990s, arising as a response to perceived failures of the second wave. and also as a response to the backlash against initiatives and movements created by the second wave. Feminist leaders rooted in the second wave like Gloria Anzaldua, bell hooks, Chela Sandoval, Cherrie Moraga, Audre Lorde, Maxine Hong Kingston, and many other feminists of color, sought to negotiate a space within feminist thought for consideration of race-related subjectivities. Types of Feminism: Liberal Feminism: All people are created equal and should not be denied equality of opportunity because of gender. Liberal Feminists focus their efforts on social change through the construction of legislation and regulation of employment practices. Inequality stems from the denial of equal rights. The primary obstacle to equality is sexism. Marxist Feminism: Division of labor is related to gender role expectations. Females give birth. Males left to support family Bourgeoisie=Men Proletariat=Women Radical Feminism: Male power and privilege is the basis of social relations. Sexism is the ultimate tool used by men to keep women oppressed. Women are the first oppressed group. Womens oppression is the most widespread. Womens oppression is the deepest. Socialist Feminism: Views womens oppression as stemming from their work in the family and the economy. Womens inferior position is the result of class-based capitalism. Socialist believes that history can be made in the private sphere (home) not just the public sphere (work). Feminism and the Media: The mass media have played an important role in the dilution of feminist goals and ideals. They often ignore, trivialize, or belittle the principles of feminism. The media employs several techniques or strategies that contribute to the negative representations of women and feminism, which are also damaging to the central goals of feminism. Women are often represented as sexual spectacles, as being on display for men. Patriarchal society dictates that women be constructed as an object for the gaze of the male spectator. Women are positioned as the passive object of the male gaze, rather than the subject in mainstream media and come to internalize this view (Dow, 1999; 1997; Wahers, 1992). Wahers (1992) describes the male gaze as the idea of men determining the specific vantage point of media depictions of women, as occupying a privileged space in the process-of contacting ways of seeing. Ways of seeing remains an important text for feminist cultural theorists who contend that women are forced to identify themselves within in a visual society constructed for male pleasure (Walters, 1999; 1992). Wolf (1992) suggests that womens attempts at achieving equality are negatively affected by images of women portrayed as sex objects. She discusses the concept of the beauty myth, which refers to how womens societal worth is based on physical appearance and youthful beauty. Walters argues that objectification of women is not an added-on attraction, but rather endemic to the very structure of image-making (Walters, 1999, p. 235). This is exemplified in media advertisements where women are frequently represented in what Wahers (1999) terms a fragmented way. Women are often signified by their specific body parts; their lips, legs, hair, eyes, etc., instead of being represented as a serious whole or subject. In advertisements women are urged to think of their bodies as things or parts that need to be molded and shaped into a male conception of female perfection. The fragmentation of the female body into body parts that women should then improve often results in women having self-hating re lationships with their bodies. Media Feminism in Pakistan: Muslim women form a highly diverse and complex group and assumptions about them are often ill-conceived, miss-informed and grossly miss-represented. This is often reflected in images of them, particularly in the West, as oppressed, powerless and victimized. The voices of Muslim women, striving to keep their religious identity in Western contexts, are seriously under-represented within academic research. In recent years there has been an increasing interest in Islamic culture as a fundamentalist and sensationalist phenomenon. Media coverage and Western scholarship often views Muslim women as an oppressed mute victim and asserts or implies that Islam itself oppresses women. Islamic Feminism and Its Role in Cinema is a study derived to counter react the portrayal of Muslim women by the media. Feminists and Muslim women activists have sought to determine the cause of discrimination against women by examining the effects on Muslim women of patriarchy, kinship and norms within Muslim and non-Muslim societies. 6 Overall trends in the published material focus on colonialism, Orientals and the media as the cause of discrimination against the Muslim womans identity. An extensive study of the research literature has failed to identify how Muslim women filmmakers represent Muslim women and whether they support feminist agenda. Critical Analysis: Movie Name: Dragon Seed (1944) Dragon Seed is co-directed by Harold S. Bucquet and Jack Conway. It received two Academy Award Nominations for Best Supporting Actress, Aline MacMahon, and for Best (Black-and-White) Cinematography, Sidney Wagner. The freewheeling plot has a heroic young Chinese feminist woman, Jade (Katharine Hepburn), who goes dressed as a man to lead her fellow peaceful farmer villagers in an uprising against the Japanese invaders. It opens in the spring of 1937 with patriarch Ling Tan (Walter Huston) and his family planting rice in the valley of Ling, China. The farmers are concerned about the recent Japanese invasion of the north, and take out their anger on Wu Lienas an angry student mob insists that he stop selling Japanese merchandise or else. When he refuses their demands, they destroy his store. Soon after the farmers observe Japanese airplanes bombing the nearby city. The pacifist Ling is shocked by the attack, but along with Lao San and eldest son Lao Ta (Robert Bice) decide to remain on their farm despite the anticipated dangers of a Japanese invasion. While Lao Er and Jade join a resistance group of refugees in the hills. Upon their departure the Japanese Army takes over the valley, and Lao Tas wife Orchid is raped and killed by the invading soldiers, who also kill Wu Liens elderly mother. Ling and his wife remain secure as they go into hiding. This cruelty drives the remaining sons of Ling to join the resistance. In the conclusion, Ling must accept that he must destroy his land so that he can sacrifice his present gains to ensure the future of his grandson. When Jade and hubby rejoin the resistance fighters in the hills to ensure a Free China, they leave their son the, seed of the dragon, in the care of his loving grandparents. The story of this movie showed that how the brave women struggles and fight for their country, she appears as a caring mother, a loving and trustworthy wife and a true patriot. The movie shows that how the heroic young Chinese woman leads her fellow villagers in an uprising against Japanese Invaders. This movie truly reflect the feminism theory.

What sparked WW1, How Did it End? :: World War I History

What sparked WW1, How Did it End? World War I was a war that took place I Eastern Europe during the years of 1914- 1918. This war involved the countries of Austria-Hungary and Serbia. The Serbians sparked these wars. In 1912, several Balkan states attacked Turkey. This sparked wars over these lands. Economic tension was also present. As international tensions grew, the great powers expanded their armies and navies. This gave the possibility of wars emerging at any time. Fear of war also gave military leaders great influence. British and German generals and admirals received the respect of the people and funding to build their forces. Serbia also wanted a South Slav empire, at this they would not stop for. A terrorist group called the Black Hand planned to kill the Archduke of Hungary Francis Ferdinand who planned to visit Sarajevo. On June 28th Gavrilo Princip assassinated Francis. Since he was under 20 years of age he was not executed. Instead he was sentenced to life in prison. He died in 1918 of tuberculosis. This severely angered the Austrians. They issued the Serbians an ultimatum. In it Austria stated to avoid war Serbia must end all anti-Austrian agitation and punish any Serbian officials involved in the murder plot. It must even let Austria join the investigation. Serbia agreed to most of the terms in the treaty, but not all. On July 28th Austria declared war on Serbia. Austria might not have declared war on Serbia if not for its longtime ally, Germany. In Berlin, Kaiser William II was horrified at the assignation of Francis Ferdinand and advised Francis Joseph to take a stand against the Serbia and assured him of German support. Instead of urging restraint, Germany gave Austria a "blank check." Serbia sought support from Russia. From St. Petersburg Nicholas II telegraphed William II. The czar asked William to urge Austria to soften its demands on the ultimatum. When this plea failed, Russia began to mobilize its troops. Russia then appealed to its ally, France. In Paris, nationalists saw this as a chance to avenge Frances defeat in the Franco-Prussian War. Italy remained neutral while Britain had to decide whether they should back their ally, France or remain neutral. Germany then decided to join the Russians and quickly defeat France in order to avoid a war on both sides of the country. This was their biggest fear.

Relaxation Destination

My day usually consists of doing homework in the morning, going to class at noon, then going to work after class. I go to class for two hours a day Monday through Friday, and work six hours a day seven days a week. A short drive to my lake house in Keystone, Florida is all it takes for me to get away. My lake house is my relaxation destination for when I need to get away from my everyday life. It only takes forty-five minutes for me to get there when driving a brisk sixty miles an hour.Just before I arrive at my lake house, I can catch a glimpse of the cobalt lake water shimmering in the sun, and begin to smell wood burning in the air. From this point on it feels as if time is standing still. When I get out of my truck, the smell of sweet bar-b-que ribs and wild flowers awaken my senses to the great outdoors. Just one look at my lake house and I am relaxed. The siding on my lake house is made of solid rough cut cedar panels. My lake house has two screened in porches; the one on the b ack of the house is used for entertaining and cooking.The second porch is on the front of the house. This is where we unwind in the hot tub, watch TV, enjoy exuberant sunsets, and listen to the melody of nature. Our porches are where I usually hangout and spend most of my time when I visit the lake house. The inside of my lake house is vividly rustic, with attractive antiques scattered throughout it. My lake house has two bedrooms, one bath, and is approximately fifteen hundred square feet. The yellow pine hard wood floors throughout the house give it a rustic feeling. All the walls in the house are painted pistachio with yellow pine trim.When I walk in the house the smell of home cooking makes my mouth water. The living room has an old cast-iron wood burning stove that comes in handy on chilly winter nights: I love to cuddle by it, and roast marshmallows with it. The living room, also called the family room is where we play board games, watch movies, and tell stories in the winter. The kitchen has Carmel colored granite counter tops and dark cherry cabinets with stainless steel handles. When I am at the lake house, it is always as peaceful as the night before Christmas that is why it is my most favorite place to go when I need to get away.

An Essay on Beowulf

Beowulf is a warrior who takes pride in fighting for others and others. Beowulf exhibits multiple characteristics of an epic hero. Beowulf is capable of things that most are not capable of during his time.   Beowulf is capable of deeds of great strength and courage. Beowulf has the courage and strength to challenge the monster Grendel despite Grendel's history and tendency to slaughter many warriors. Grendel is a giant monster that is unharmed by human weapons, forcing Beowulf to use nothing but his bare hands. This battle boosts Beowulf's resume proving that he has great strength and courage since Beowulf took on the challenge that most of the warriors were afraid of. Beowulf's strength is displayed when he uses bare hands to rip off Grendel's arm. Beowulf goes underwater to battle with Grendel's mother with the courage to pass through multiple sea monsters. This demonstrates Beowulf's courage since he went through what the other warriors were afraid to, knowing that his life could be taken by Grendel's mother or the sea monsters. Beowulf returns from his home to put an end to the dragon that has been terrorizing the Danes. Beowulf is of old age at this time but arrays great strength and courage by going to the dragon's home, with the help of only one other warrior, aware that he may not make it out alive. Beowulf's strength and courage set him apart from the average warriors. Beowulf faces supernatural foes in his battles. Beowulf faces Grendel, but Grendel is unharmed by any ordinary weapons. Beowulf's approach to fighting Grendel must be different than human battles. Grendel's supernaturalism is emphasized by the warriors' swords inability to harm him. Beowulf battles with the supernatural dragon that was terrorizing Hrothgar's men. The average warriors are not able to tame the dragon. The dragon possessed flames and poison that naturals did not own. Beowulf goes to Grendel's mother underwater lair to defeat her. Beowulf's natural sword cannot penetrate her skin since she is a supernatural evil foe. The sword that Beowulf attempts to use would penetrate the skin of an average person, but human weapons fail against Grendel's mother since she is supernatural. Beowulf partakes in battles and victories against foes with immortal abilities that regular or ordinary warriors cannot handle. Beowulf owns the credibility of a great warrior. Beowulf boasts stating, â€Å"I drove Five great giants into chains, chased All of that race from the earth. I swam in the blackness of night, hunting monsters out of the ocean and killing them one by one† (Lines 151-158). Beowulf has fought many sea monsters in the ocean giving him an accomplishment to support his boasting of ability. Not many, if any, of the warriors could overcome five great giants. Beowulf fought a swimming match with Brecca in the deepest and dangerous seas. Beowulf has the proof behind his boasting since no man could swim and fight off monsters in the seas like him. Beowulf is an established and accomplished warrior before he even fights his biggest battles for Hrothgar. Beowulf possesses characteristics and abilities that define him as an epic hero. Beowulf takes on tasks or challenges that the average warriors do not have the capability of doing. Beowulf solidifies his already impressive resume in his battles in Daneland.

Anchisaurus - Facts and Figures

Anchisaurus - Facts and Figures Name: Anchisaurus (Greek for near lizard); pronounced ANN-kih-SORE-us Habitat: Woodlands of eastern North America Historical Period: Early Jurassic (190 million years ago) Size and Weight: About six feet long and 75 pounds Diet: Plants Distinguishing Characteristics: Long, slim body; ridged teeth for shredding leaves About Anchisaurus Anchisaurus is one of those dinosaurs that was discovered ahead of its time. When this small plant-eater was first excavated (from a well in East Windsor, Connecticut, of all places) in 1818, no one knew quite what to make of it; the bones were initially identified as belonging to a human, until the discovery of a nearby tail put an and to that idea! It was only decades later, in 1885, that the famous American paleontologist Othniel C. Marsh conclusively identified Anchisaurus as a dinosaur, though its exact classification couldnt be pinned down until more was known in general about these long-extinct reptiles. And Anchisaurus was certainly strange compared to most dinosaurs discovered up to that time, a human-sized reptile with grasping hands, a bipedal posture, and a swollen belly populated by gastroliths (swallowed stones that aided in the digestion of tough vegetable matter). Today, most paleontologists consider Anchisaurus to have been a prosauropod, the family of svelte, occasionally bipedal plant-eaters of the late Triassic and early Jurassic periods that were distantly ancestral to the giant sauropods, like Brachiosaurus and Apatosaurus, that roamed the earth during the later Mesozoic Era. However, its also possible that Anchisaurus represented some kind of transitional form (a so-called basal sauropodomorph), or that prosauropods as a whole were omnivorous, since theres (inconclusive) evidence, based on the shape and arrangement of its teeth, that this dinosaur may occasionally have supplemented its diet with meat. Like many dinosaurs discovered in the early 19th century, Anchisaurus has gone through its fair share of name changes. The fossil specimen was originally named Megadactylus (giant finger) by Edward Hitchcock, then Amphisaurus by Othniel C. Marsh, until he discovered that this name was already preoccupied by another animal genus and settled instead on Anchisaurus (near lizard). Further complicating matters, the dinosaur we know as Ammosaurus may actually have been a species of Anchisaurus, and both of these names are probably synonymous with the now-discarded Yaleosaurus, named after Marshs alma mater. Finally, a sauropodomorph dinosaur discovered in South Africa in the early 19th century, Gyposaurus, may yet wind up being assigned to the Anchisaurus genus.

Free Essays on Gatsby

Symbolizing the American Dream F. Scott Fitzgerald’s classic novel The Great Gatsby examines the 1920s vision of the American dream. It shows how the American dream is corrupted by wealth and power. Gatsby is a firm believer in the American dream of self-made success. He has achieved this dream, but he also has a dream of being with Daisy. Gatsby is successful, but his success is through new money. There is a difference between old money and new money. The people with old money give no respect to the people with the new money. This is shown by Tom calling Gatsby’s car a â€Å"circus wagon† (128). The social flaw of being new money imprisoned Gatsby on an emotional island. The novel uses a major literary theme to show hidden meaning. The technique of symbolism is included into the novel. The author uses symbolism by showing how the American dream can be corrupted by wealthy people with little or no morals. Fitzgerald incorporates three symbols to prove this; they are the green light at the end of the Buchanan’s dock, the eyes of Dr. T. J. Eckleburg, and the valley of ashes. At the end of the Buchanan’s dock was a â€Å"single green light† that Gatsby reached toward (26). Green is a color that represents promise, hope, and renewal. This green light symbolizes Gatsby’s hope that the present will change to that of a great future, one where dreams come true and the where American dream is realized. His most important dream is his longing for Daisy. As Sulton said, â€Å"At this point in the novel, Gatsby can only reach longingly, from a distance toward a light he associates with his former lover.† Gatsby’s also sees the green light as a symbol of immense possibilities. Gatsby uses Nick Carraway as a window to the desperately needed green light. Nick is used as a gateway to Gatsby’s goal, Daisy. Gatsby has spent his whole life longing for something better. The green light stands for all of Gatsby’s hopes... Free Essays on Gatsby Free Essays on Gatsby The Great Gatsby, written by F. Scott Fitzgerald, is a specific portrait of American society during the Roaring Twenties. It tells the quintessential American story of a man rising from rags to riches only to find that his wealth cannot grant him the privileges of class and status. Although the central character of the novel is Jay Gatsby, a wealthy New Yorker known mostly for the lavish parties he throws every weekend at his mansion. The narrator, however, is Nick Carraway, a young mid-westerner from a prominent family who came to New York to enter the bond business. Even though Nick Carraway is involved in all of the events of the novel, he does not play a significant active role. Carraway’s characteristics of being responsible, honest, and fair makes him a reliable narrator. Nick's description of himself in the opening chapter holds true throughout the novel: he is â€Å"tolerant and slow to judge, someone with whom people feel comfortable sharing their secrets† (Fitzgerald 7). Carraway has this willingness to describe himself and the contours of his thoughts even when they are inconsistent or incomplete. Toward the end of the novel, his long musing makes him seem thoughtful and trustworthy. His discusses Gatsby’s dream of loving Daisy, but he tells it as Gatsby’s struggle to recreate the past in the future. He realizes failure, â€Å"the quality of distortion† that lures people to the East disgusts him (Fitzgerald 123). â€Å"Individuals must now struggle like rowboats against a current, as they move forward with their dreams into the future, but are borne back ceaselessly into a past they (like Gatsby) are doomed never to recreate† (Plotz 32). Nick Carraway’s position in relation to the other characters gives him a perfect vantage point from which to view the story. He is Daisy's cousin's old college friend, and Gatsby's neighbor. They all trust him and rely on him. Nick Car... Free Essays on Gatsby 1) The first party that takes place in East Egg at Daisy and Tom's mansion. Since Daisy is his cousin and Tom, a friend from Yale, Nick has the credentials to visit East Egg. Their house is "a cheerful red-and-white Georgian Colonial Mansion" overlooking the bay. And the owner is obviously proud of his possessions. We meet Tom who is presented as a powerful man in riding clothes sort of as a knight. We then meet Daisy and Jordan who seem like two princesses in white sitting on the sofa. Fitzgerald controls the whole scene through his use of colors white and gold mainly that suggests a combination of beauty and wealth. Jordan Baker is bored and discontented. She yawns more than once in this very first scene. Tom talks about a book he has read, The Rise of the Colored Empires by Goddard. It is a piece of pure Social Darwinism, advocating that the white race preserve its own purity and beat down the colored races before they rise up and overcome the whites. Daisy pretends she does not know is going on by teasing him about his size and the big words in his book. Then the telephone rings and Jordan sort of fills Nick in on what's going on about Tom and his "other woman". The rest of the evening is awkward and painful and both Tom and Daisy try and pretend nothing happened. The second Party takes place in New York and consists of Nick, Tom, Myrtle, Myrtle's sister Catherine, and a couple named McKee who live downstairs. Nick is really more of an observer than a participant. He tells us that he has been drunk just twice in his life, and the second time was the at afternoon. In any case, all the guests at the party seem to have something unnatural or wrong with them. Catherine, the sister, has "a solid, sticky bob of red hair, and a complexion powdered milky white. Her eyebrows had been plucked and then drawn on again at a more rakish angle." Mr. McKee is a pale, feminine man who has just shaved and left a spot of lather on his cheek. His wife...

Free Essays on Gatsby Gatsby’s Hopes and Dreams for his Future The Great Gatsby by F.Scott Fitzgerald is recognized in American Literature as one of his greatest achievements. Many of Fitzgerald’s works research the Jazz-Age for the single American dream of happiness and wealth (Poupard, Person 146). â€Å"Critics concur that The Great Gatsby rises above being a mere chronicle of a past American era, and most believe that the novel’s continued popularity demonstrates modern America’s fascination with the American dream† (Poupard, Person 147). In this book Fitzgerald uses Gatsby to compare the real American dreamer with what has become of the American society in the 1920’s. During the 1920’s America was unable to fulfill dreams and expose the blindness in Jazz-Age Americans. â€Å"The Great Gatsby is an exploration of the American dream as it exists in a corrupt period, and it is an attempt to determine the concealed boundary that divides the reality from t he illusions† (Bewley 38). Jay Gatsby is a builder as! well as a dreamer, and Gatsby puts his all into figuring out his â€Å"ethical dream† (Minter 82). The Great Gatsby was written in a poor society with no moral virtues. Dreamers in a healthy society are respected and encouraged. However, in the twenties these people weren’t treated with the respect they deserved. â€Å"Gatsby’s dream divides into three basic and related parts: the desire to repeat the past, the desire for money, and the desire for incarnation of ‘unutterable visions’ in the material earth† (Lockridge 11). In The Great Gatsby, Jay Gatsby will do anything to fulfill his hopes and dreams. Gatsby does not fulfill his hopes and dreams in his lifetime. No one knows where Gatsby comes from, what he does, or how he has become so wealthy. But in the middle of the novel Nick Carraway, the narrator discovers that Gatsby was born Jay Gatz in North Dakota. Gatsby also tell Carraway about his schooling. Gatsby says, â€Å"I am the son ... Free Essays on Gatsby â€Å"The Great Gatsby† By: F. Scott Fitzgerald In the â€Å"The Great Gatsby† by F. Scott Fitzgerald, although the book is named for James Gatz, the main character is Nick Carraway, who also acts as the novel’s narrator. The narrators of many novels are not significant to the plot and just serve the purpose of telling the story. Nick, however, is quite the opposite. Though he may not seem to be the main character next to Gatsby, Nick is the one person in the book who is linked to every character and in turn connects them all to each other. Although he is more of an observer than anything in this novel, and is inclined to reserve his personal judgments, he also tries to remain uninvolved and is reluctant to act upon what he perceives to be faults of others. After his return from War, Nick decides to move to New York in the summer of 1922 to learn about the bond business. He rents a house in the West Egg district of Long Island. One weekend Nick gets together with his cousin Daisy and her husband Tom Buchanan, a rich man who lives in West Egg who is having an affair with a woman named Myrtle, the wife of George Wilson, a Gas Station owner. On this night Nick is introduced to Jordan Baker, a friend of Daisy’s and an acquaintance of Gatsby Nick's neighbor in West Egg, who lives in a gigantic mansion and throws extravagant parties every Saturday night. Nick is invited to attend one of these parties and he and Jay soon become good friends. Both have things in common, one being they both know Daisy Buchanan.

Review - Article Example or agricultural usage, the resultant man caused fire event releases massive amounts of bio-mass particulates and aerosols into the atmosphere above Amazon. The pressing concern is how this pollution is affecting cloud formations and how the loss of those clouds may be causing a shift in the weather patterns that could threaten the entire Amazonian ecosystem. Scientists Ilan Koren, and Lorraine Remer from the Weizmann Institute collaborated with Karla Longo from the Brazilian Center for Weather Forecasting and Climate Studies to construct a research model to better understand how smoke changes clouds in the Amazon. Smoke changes the size and number of cloud droplets, which affects the cloud density and the visual â€Å"brightness† of cloud formation. In theory this smoke layer, stabilizes and creates layers within atmosphere that directly suppresses updrafts that fuel cloud formation. Clouds are better at reflecting sunlight back into space than smoke, the scientist’s hypothesis considers that fires in the Amazon likely allow more solar energy than normal to enter the Earth’s climate system and are contributing to far reaching examples of climate change. The scientists collected data from the Moderate Resolution Imaging Spectroradiometer (MODIS) system at NASA’s Goddard Space Center. The MODIS satellite data was compiled and analyzed over an 8 year period (from 1998 to 2006). The research initially focused on how smoke influenced clouds on a day to day basis. But, as the study progressed the scientists noted that since 2000, there were large fluctuations in the density and proliferation of smoke between the years. Some years were relatively clean, and in other years the atmosphere was being highly polluted by the smoke from the man caused fires. When this was noted the scientists bi-furcated the research and looked at additional MODIS data from AVHRR (Advanced Very High Resolution Radiometer) to look at look at the daily and monthly averages in the number of

Fashion Buying and Merchandising - Essay Example The paper "Fashion Buying and Merchandising" concerns the process of Fashion Buying and Merchandising. The United Colors of Benetton have missed the fashion colors for the spring / summer collection of 2011, specifically because of the colors which aren’t bright or fashion forward. To change this, a capsule can be created to fulfill the gap and change the way in which the approach is taken. The capsule will not only consist of the changes in colors, but will also continue to include the ideal of comfort that the United Colors of Benetton approached toward the season The result will be the ability to combine the current parts of the fashion which was noted to have a better approach with the trends of the season based on colors. The focus for this particular capsule will be to expand on the shapes and key features which have already been introduced by the United Colors of Benetton. While there was a lack of the right coloring, there were some elements which could be considered w ith the clothing, specifically with the styles and shapes that were included in the various pieces of clothing. The capsule created will combine new types of fabric and colors with the shapes and styles which were currently introduced by the United Colors of Benetton for the Spring / Summer collection.

How to make current handgun control laws stronger, and more Research Proposal

How to make current handgun control laws stronger, and more enforceable - Research Proposal Example Instead it offer an umbrella protection to everyone by making laws which are definitely worth their weight in gold but are not actually imposed by all states. The gaps between state and federal gun control laws make the problem even worse. Federal gun control policy is simple: firearms must not reach irresponsible or dangerous people. This approach is particularly uncontroversial and hence approved by most quarters. Some of the key laws in this regard are the 1968 law passed in response to the killing of Robert Kennedy, the federal law prohibiting sale of firearm without background check, and prohibition on sales to illegal aliens. These laws should have been good enough to stop some incidents like the Virginia Tech massacre but the reason they failed lies in gaps existing between state and federal laws. Due to these gaps, Seung-Hui Cho was never reported to the federal police as he has already been termed mentally ill. According to 1968 federal law, people who are "adjudicated as a mental defective" are prohibited from possessing firearms. This is probably the most significant piece of legislation on gun control in last 50 years. Even though attempts have been made to pass other laws too, none have been as significan t in their impact as the Gun Control Act of 1968. The main objectives of the Act were as follows: (1) Eliminating the interstate traffic in firearms and ammunition that had previously frustrated state and local efforts to license, register, or restrict ownership of guns. (2) Denying access to firearms to certain congressionally defined groups, including minors, convicted felons, and persons who had been adjudicated as mental defectives or committed to mental institutions. (3) Ending the importation of all surplus military firearms and all other guns unless certified by the Secretary of the Treasury as "particularly suitable for ... sporting purposes."2 The country needs stricter gun control laws but a recent US Supreme Court decision may give another message. In June 2008, US Supreme court gave an emphatic nod to firearm owners when it overturned a Washington DC ban on possession of guns. No other recent decision was as vital in significance as this one since it offered an interpretation of the Second Amendment and also explained how constitution treats the subject. In writing the majority opinion, Justice Scalia, ruled that the Constitute does not infer "the absolute prohibition of handguns held and used for self-defense in the home.3" For this reason gun control laws are definitely one of the most controversial issues in the country. Even though we acknowledge the need for stricter gun control laws, the Supreme Court interpretations of the Constitutions and other rights, often create a hurdle for the implementation and passing of these laws. Jenson (2007) writes: "Gun control legislation has had a long and inconsistent history in the United States. Congress first passed laws controlling firearms in the early 20th century. Throughout the past century, the issue has been debated frequently by opponents and proponents. Each side has used a different interpretation of the Second Amendment of the Constitution, a provision giving citizens the right to bear arms, to boost its arguments for or against gun control.

Homework #6 - Essay Example The ideology is driven from the whole concept of use-value, exchange-value and commodity. Marx defines the Fetishism ideology into themes. He first states that the exchange-value of a commodity depends major on the labor used in its production process. When determining the value of a product one will tend to use the commodity to compensate the labor. The commodity in his ideology is dependent since it relays on what efforts invested in terms of labor. He also explains the social relation between producers and eternal factors. He shows how different producers relate despite their difference in commodities they offer in the market(Wood, 1970). He uses the relativity of the products to create a personal concept of the market. For instance, one who makes tea and sells directly relates to who bakes cakes and bread. He finally states laboring activities controls the activities of a product. In a real life scenario, the exchange of commodity follows the concept of Money- Commodity- money. This means that one sells a product in order to generate more money and utilize it to make offers and expand productivity. Karl Marx on the other hand explains that money is replaced in its commensurability with human labor (Wood, 1970). Thus, his structure is Commodity- money- commodity. Different from this the fetishism ideology with real life is the fact that labor used while producing does not necessarily reflects the product. In that while, producing one may fall ill and hence spends resources in treating himself hence the final product will not reflect the amount of resources used in the production. Socially it clearly shows how the people relations in the production line as were the case of the tea maker and the cake baker clearly shows a contrasting relation different from what Marx stated. They fail to relate in terms of the exchange value in that they independently fix the value without considering what the other person will react (Wood, 1970). In this

Stress and Coping Mechanisms of First Year Principals Dissertation

Stress and Coping Mechanisms of First Year Principals - Dissertation Example Explaining the fundamental basis of stress as a reaction towards demands on the body, the Mountain State Centers for Independent Living (2010) expresses the view that stress involves the release of body chemicals that â€Å"give people more energy and strength, which can be a good thing if their stress is caused by physical danger.† However, it is alarming that in a particular group of people, the levels of stress recorded among them should be rated as high. This is because high levels of rising stress impacts the victims in several ways including the work they do and their health (Foxall et al, 1990: 580). This argument says a lot about why principals are stressed most of the time. Having noted that a person’s duties could determine the level of stress to be experienced by the person, it is just right to state that principals are often stressed because their work comes with a lot of mental demands that requires them to use their brains very often. Knowing that principa ls undertake a lot of academic responsibilities that strain their brain, stress is thus inevitable for them. In a typical educational institution, principals are expected to among other things supervise the activities of other teachers, initiate academic itinerary, organize school examinations and in some cases serve as examiners. They also go an extra mile to execute other duties including being in charge of every sector of the school development; ranging from meeting the educational needs of students to providing the necessary materials and supplies for the teachers to implement the curriculum. They do this under strict monitoring by the stakeholders, board members, the superintendent, and the state and national educational leaders. New mandates are frequently imposed on already high expectations. A mountain of meeting, queries and complaints from parents, playground and lunchtime duties are also the order of the day for most the principals. All these are roles that are expected t o be executed with perfection and accuracy. In a bid to do all these, principals; especially first year (inexperienced) principals who are mostly new on the job end up stressing themselves badly. The work of the principal is one that is associated with a lot of physical and mental pressure. This is even worse because most principals (both inexperienced and experienced) are involved in academic based professions and occupations that involve the strenuous use of the brain rather than physical strength. Examples of these professions include medicine, nursing, law, teaching, pharmacy, writing and the like. Among this group also, teachers, including lecturers have been found to be one of the worse hit (Lee, 2003). It is worth noting that the work of lecturers and educators, especially those on higher ranks like principals involves a lot of demanding tasks that include multi-complexities. For instance there is mental application of knowledge, physical application of strength and regular i nter-personal interactions. In a typical school environment or school situation, principals (inexperienced and experienced) take the role of academic overseers over student, as well as the administrative activities. The year principal are, therefore, almost all the time involved in one kind of engagement or the other. In most situations, the situation of principals is worsened when they have other responsibilities other than academic roles to play. Some of these

Giant Panda and Wildlife Conservation Essay Example for Free

Giant Panda and Wildlife Conservation Essay Wildlife conservation is the most important things in the world. And people have made a lot of progress in this field. In wildlife conservation, people try their best to protect endangered plants and animals, as well as their habitats. The purpose is to make sure that future generations will have enough space to survive and develop well. Countries all over the world have different agencies for wildlife conservation and plenty of nonprofit organizations also take part in the process of this activity. Various kinds of subjects are involved in the process of wildlife conservation. For example, people must use the knowledge in the field of biology and other sciences to recognize the species that are in danger, and to study those species to learn more about their needs. Economics is also involved in wildlife conservation, because the conservationists are trying to find out the most efficient solutions. Apart from these, the protection of wildlife also depends on education very much, using different methods to teach people about the importance of animal habitat conservation. However, the Earth is warming, and humans are using more water than ever before. It is important to know how people save wildlife around the world especially conservation in China, the U. S . and then when happens after conservation especially the governments role in the process to protect wildlife, as well as the effects of these measures. Conservation in China China has a vast variety of species, with the number of mammal species ranking second all over the world. In terms of reptiles and amphibians, China’s ranks are the fourth and sixth respectively. Although China only ranks eighth when it comes to its bird species, there are still about 1,244 types of birds in this country. A lot of these bird species are native to China, and that is why China has the responsibility to protect their future existence. There are sixteen primate species living in China. However, in the northern part of the tropical area, China has precious species such as the Sichuan golden monkey, which can also be found in Hubei as well as Sichuan provinces, and the Yunnan golden monkey, which lives in high-latitude places covered by snow of about 4,270 m. (Harris, 2007).. Golden monkeys, tigers, and pandas are rare and protected animals in China. In China, however, the most famous endangered species of wild animal is definitely the panda The panda is an endangered species of wild animals, and it can only be found in China. So people can say that panda is Chinas unique wild animal, so the protection of this animal is essential. The habitat of pandas lies in the provinces within China’s â€Å"Great Opening of the West†. The place is so fragile and unique that people can only run tourism on a small scale as the only economic activity. Therefore, it is extremely essential to create more nature reserves for the protection of pandas, even though some of them are not working effectively. If we do not pay most of the attention to allocating these areas as habitat for pandas, these places will definitely be used for producing wood and or agricultural crops. Recent survey in 2004 found that many threats including deforestation and persistent poaching interfere with the long-term survival of this endangered species. (Harris, 2007). For instance, Western development for pandas makes Chinese poachers see business opportunities and their harmful behaviors have seriously affected the survival of this precious animal. Human development has affected wildlife survival environment. Because of the population explosion and unsustainable use of natural resources, the panda habitat is also rapidly losing. Pandas adhere to living in a large area of natural forests, which can also be used for agriculture, timber and firewood. Because of Chinas dense population, many of the giant panda population is isolated in no more than 1093-1312 yards wide narrow belt of bamboo. Because of immigration, the pandas habitats are continuing to disappear. In more than 20 pandas range, there are many habitats fragmentation into isolated areas. In these areas, a network of nature reserves exist to protect more than half of the panda population. Because of the requirement for habitat, the giant panda cannot migrate, so they have lost a lot of flexibility as they are not able to find new feeding areas. (Calhoun, 2005). In China, humans’ over-exploitation of trees and the destruction of environment have also caused a large number of pandas to disappear. Moreover, China has no ability to build adequate reserves to protect the panda. Conservation in the United States America is a country with a focus on animal protection and people there treat animals as their close friends. The country of United States has a broad geographical location and there are many kinds of views in the United States, from the polar ice to tropical rain forests, from moderate rain forests to prairies, from mountain summits to desert and coral reefs. There are some places to live, comprising the most richest land on the Earth, such as the lower Mississippi River and the western salt marshes which are some of the most barren areas. Wonderful and various kinds of animals live in many places of this country, such as elk, wolverine, bison, grizzly bear, bald eagle, musk ox, caribou, wolf ,mountain lion, polar bear, and moose, which are booming in these areas. It is also the habitat of thousands of amphibians, fish, bird and reptiles. (â€Å"Wildlife Conservation Society,†n. d. ). Americans attach great importance to the protection of animals and people in the United States to give animals a lot of living space and a good natural environment. In order to ensure the survival of wildlife in the United States, people have founded a vast area of nature reserves. In terms of conservation innovation, the U. S. has a rich history. The U. S. created Yellowstone, the crown jewel of parks in 1872, establishing the concept of national parks. And then in 1932, the first International Peace Park, Glacier-Waterton National Park along the border with Canada was created. Even with a vast system of public lands which provides protection for the wild places in the country, including national parks and wilderness areas for fishing and wildlife refuges and state lands, there are still some conservation challenges caused by management activities on the public lands. Usually, more efficient private lands are a vital component of long-term success in conservation. (â€Å"Wildlife Conservation Society,†n. d. ). The Yellowstone national park is one measure to guarantee the protection of their animals, since the place gives wildlife enough living space. Yellowstone national nature reserve gave wild animals more opportunities and space. People also try their best to protect wolves in the United States. In March 2003, the U. S. fish and wildlife service issued a rule, significantly reducing federal protection for wolves and set the stage to liminate them from the endangered species act (ESA) protection completely. Until now, in terms of the recovery in the number of wolves in the 20th century, the U. S. fish and wildlife service has done a great job. People take wolves into the Yellowstone national park and central Idaho. This protection is considered by many to be one of the great achievements. (Calhoun, 2005). The United States fish and animal protection administration also obtained remarkable achievements in protecting the wolf population. After Conservation After the management of protection on animals by volunteers, the joint efforts of the China panda protection finally result. Recently, the world natural foundation has helped the Chinese government in the field of national habitats of giant panda and its protection program. This program has made significant progress: China now has 33 of the giant panda reserves, and the giant panda habitat reaches around more than 6177 square miles of area. According to a survey in 2004, there were 1600 pandas in the wild. (Calhoun, 2005). With the help of the animal protection association of America and China, multiple reserves are established. China needs more reference to the United States in protecting wild animals. Wildlife protection is the responsibility of people around the world. Chinese and Americans need to learn from each other about how to protect endangered wildlife better in the future. China should, for example, learn from the United States some new ideas of animal protection and the responsibilities of ordinary people when it comes to animal protection in the wild. Through the study of wildlife conservation concept, people in China can improve their animal protection measures, reduce cutting down trees and causing environmental damage any longer. Strengthening the reserve management and reducing the poaching practice, these measures will better protect endangered wild animals. The United States in the field of conservation philosophy occupies a leading position in the whole world. For instance, American people created Yellowstone national park and the international peace park. These huge areas provide plenty of living space for wild animals. China also has an extensive area, so there are a lot of important lessons China can learn from the United States, such as creating national parks and nature reserves in the areas which are suitable for specific kinds of animals. In the meanwhile, if necessary, China may also seek some help as well as advice from the United States. Conservationists work all over the world. To determine the species need to aid and protect them. The subject usually include animals and raise them. Capture prisoner ensure still large and diverse population at the same time environmentalists work establish territorial animals, so they can have a safe place in the field. Wildlife conservation needs also need to be balanced with other desires, because many countries value forms of entertainment like hiking in the wilderness, camping, hunting and makes it impossible to set aside land makes wild animals live. In this respect, China only attaches great importance to the development and demand of human beings. Ignored, the environment and wild animals, and other important factors.

Impact of Weather on Dengue Disease

Impact of Weather on Dengue Disease Dengue is the most tropical infectious disease that is transmitted by the Aedes aegypti mosquito. The dengue disease incidence rises as a serious public health problem with 2.1 billion people at risk. In Malaysia, the dengue disease over the last 40 years has become worst epidemic in the countrys history. This study aimed to analyses relationship between weather parameters and increase of dengue incidence among university Putra Malaysia students, to identify the direct or indirect effect of weather on dengue incidence and to determine the relationship of dengue disease located in UPM (SERDANG). The objective of this study was to assess the effect of meteorological parameters variation on the dengue virus transmission between UPM students. We obtained data on monthly weather parameters including relative humidity and median mean temperature and rainfall amount and monthly dengue cases. Analysis was conducting by employing correlation and regression, plotting. A total of 7 years of den gue occurrences since 2005 to 2011 were plotted, 2005 and 2010 were the highest years with dengue cases rates while, 2006 and 2007 were the lowest dengue incident rates. Analysis of monthly mean temperature data for UPM indicated that the months which having very warm days has higher dengue rates while, the precipitation months has more direct effect on these rates. On the other hand, humidity is the most factors have highest impact on dengue incidence between UPM students. Keywords:  Weather impact, dengue incidence, UPM students. INTRODUCTION Dengue fever (DF) and Dengue hemorrhagic fever (DHF) possess recurred as 1980s and rapidly come to be a main epidemiological menace worldwide; especially in South East Asia and Western Pacific Region. Dengue fever is rampant in more than 120 countries alongside approximated 2.4 billion populations at the chance and annual dengue infection of 52 million cases according to World Health Organization, (WHO, 2005). Of this, Asia Pacific Area shares the biggest burden of dengue alongside approximated above 75% of the 2.5 billion populaces at chance living in the region. As yet, the particular causes for the re-emergence of dengue are not completely comprehended. Though, the U.S. centers for Disease Control and Prevention has recognized factors such as weather factors and accelerated urbanization, poor areas, increased global excursion, and lack of competent vector manipulation arrangement as a few of the main determinants that possess gave globe rise of DE/DHF as a main area condition burd en (U.S. C.D.C.P,2007). In Malaysia Dengue considered as endemic disease with four serotypes of dengue viruses. Dengue is the most threaten disease to public health in Malaysia. Around the world 50 million cases are reported each year about the dengue disease infection (WHO, 1999). Dengue is endemic in Malaysia the first case was recognized in Penang 1902, while the first dengue hemorrhagic fever outbreak was reported in 1962, likewise in Penang (Ska, 2006). . In the year 2005 MALAYSIA experienced the worst past outbreak of dengue incidence alongside 326.5 cases each 100,000 populations. The overall dengue cases in Malaysia augmented from (39,597 person) and (84 person deaths) in 2009 to (45,037 person) and (133 person deaths) in 2010 (HM, 2010). It is notifiable that Selangor state has the highest (dengue cases) followed by (Johor and Sarawak) for 2010 (MOH, 2010). The urban and also rural areas of Malaysia are the greatest predominant habitations for the spread of the (yellow fever mosquito) species which is Aedes aegypti (Mohd et al., 2006). The mosquitoes of yellow fever can be found in the area of stagnant water and also in severe drainage (Mohd et al., 2006). The patients of dengue will suffer symptoms include vomiting, rashes on the skin, headache, nausea and muscle pain (NCID, 2005). Recent Studies have shown that temperature could have an impact on feeding characteristics, population size, maturation period and survival rate of Aedes mosquitoes and pupae, and larvae mature female mosquitoes mortality rate as a function of temperature Between 11  °C and 42 °C. (Hii, Y et al .2009). Many Studies shown that the high temperature have an impact on the population magnitude and maturation period, the survival rate of Aedes mosquitoes and the Feed characteristics. Aedes mosquitoes on temperature which ranging from 16 °C to 31 °C, experience lower mortality rates , a study in French Guiana illustrated that at favourable environment condition Aedes mosquitoes capable to live 76 days . On the other hand, heavy rain decrease survival rate of female mosquitoes and destroys larvae in short time but in long term, it creates plentiful breeding resources. Simultaneously, Aedes mosquitoes at a higher temperature 32 °C rises feeding frequency more than twofold compared to the temperature at 24 °C. Extremely Low rainfall rates will increase surroundings temperature, usage of water storage and water and air-coolers may serve as breeding habitats. Finding the relationship between weather factors mainly (temperature, rainfall, humidity) It can be useful for prioritizing prevention in public health sector decision making.. A threat prediction of dengue outbreak can be produced so local health officials can expect the number of cases and make proper strategy to control it. Example The dengue disease epidemic has become more serious problem in serdang with increasing about 14 percents for 2011 (Mstar, 2011). Selangor state recorded highest cases of dengue incidence compared to other states (MOH, 2010). For Seri Kembangan area, the dengue disease epidemic noted the 75 cases on 2009 while for year 2010, a total of 158 cases were reported (Mstar, 2011). The major source of Aedes mosquito breeding is in factories, abandoned housing projects, from the construction sites and vacant plots land (Thammapalo et al., 2001). The aim of this study an association amid dengue incidence and mean temperature, humidity and rain also more discuss how meteorological conditions impact on the rise of dengue in Universiti Putra Malaysia across the period 2005-2011 and to identify the most high risk years with dengue incidence. The result of this study will be highlighting the connection between dengue cases and weather parameters within Seri kambangan 2005 2011. Health sector planners and policy makers benefit from this kind of studies as it generates useful information which further can be used for the creation of schematic approaches for disease prevention, interceptive studies and control programmes. This study is important as it can help in delaying or reducing the incidence of disease and its related socioeconomic implications at the individual and the community level as a whole. Results achieved were used to recognize the patterns of dengue cases and the degree of dependence of dengue incidences on the weather parameters. In this study, we tried to provide additional details on relationship between dengue rates with weather parameters. Attention was focused on four years with lowest dengue incidence (2006 and 2007) also the highest two years with dengue cases (2005 and 2010) were inspected, and statistical analysis has been done to find evidence on the degree of correlation between the dengue and climate factors (precipitation, relative humidity ,temperature). METHODOLOGY 2.1 Study area Universiti Putra Malaysia is a public school which is approximately 22 km south of capital city Kuala Lumpur by road which located at latitude of 2 °59 ´57Ë  N and longitude of 101 °42 ´28Ë  E. The main campus of UPM is located at Serdang, Selangor state which cover an area of 1,200 hectares of spectacular natural landscape and the topography is between 49m to 52m above sea level (figure 1). Universiti Putra Malaysia has a population of 29,724 in first semester of 2011/ 2012 session. The staff population is 6,100 that include academic, non-academic and sporting staff while that of student is 23,624 which include post graduate and undergraduate students. Out of the total population of students, only 14,108 are residing on campus while others stay off campus. The Malaysian peninsula has a typical equatorial climate characterized by constantly high annual temperature and heavy rainfall. Temperature range is practically the same all over Malaysian peninsula throughout the year and is only governed by the height of the land above sea level; there are important differences in the amount and seasonal distribution of the rainfall in different part of the country. An average mean rainfall is about 2489mm which distributed throughout the year, with the bulk of the rain concentrated in the month of October and November, and its rains comparatively less in May to September (dry season) than October to April (wet season).Monthly average temperature are high on the month of April and May while December and January are the months with the low average temperature. Mean daily dry season (May to August) temperature range from 31 °C to 34 °C and the mean daily wet season (November to February) temperature range from 29 °C to 32 °C. 2.2 Data Source The Weather parameters data of UPM (2005- 2011) was obtained from Malaysian meteorological department (MMD). Temperature had estimated This data was distributed into monthly data per year. This parameters which include (rainfall, humidity, mean maximum temperature) has been used to understand degree of dengue fever dependence on weather parameters (Morrison et al., 1998). Dengue epidemiological data monthly basis and annually was obtained from UPM PUSAT KESIHATAN from (2005 to 2011). dengue haemorrhagic fever (DHF) or dengue fever (DF) were recognized as clinical dengue cases with confirmed laboratory blood tests of dengue viral infection of any serotypes Under the Infectious Diseases Act in Malaysia, it is needed for all medical practitioner must inform all confirmed or recognized dengue cases within 24 hours to the Ministry of health. (Infectious Disease Prevention and Control Act 1988). The only data which obtained from UPM PUSAT KESIHATAN were number of monthly and annual cases. 2.3 statistical analyses All the dengue cases were plotted in the graph by using Minitab 16 version. Calculating and investigating the variability of rainfall, humidity and temperature indices, creating scatter plots and charts of Dengue fever cases against meteorological conditions variables, correlation analysis.( Amarakoon et al.,2004). Here we analysed the association of rainfall and temperature, Humidity alongside dengue transmission in every single year in University Putra Malaysia. We only exclude 3 years owing to the very small dengue cases. The cases of dengue disease were examined includes geographic distribution and spatial gender distribution (Srivastava et al., 2009). The purpose of geographic distribution is to determine the distribution of dengue cases among Kuantan district. Apart from that, the gender distribution was categorized into two groups which were male and female. The statistical significant between both gender were analyzed by using t-test. 2.3.1 Spatial distribution The spatial distribution of dengue incidence within concession of Kuantan was observed. The spatial autocorrelation method measures the relationship among values of variable according to the spatial arrangement of the values (Chang, 2010). The Morans I method was selected to test whether the dengue cases within Kuantan district is spatially correlated or not (Er et al., 2010). The area units where numerical ratio or interval data were available were the area where the Morans I normally applied (Nakhapakorn Jirakajohnkool, 2006). It considers both point locations and variation of an attribute at the location and finally it can evaluate whether the pattern of dengue cases within Kuantan district were clustered, dispersed or random. The Morans I measure can be compute by (Er et al., 2010): Where N is the number of cases, is the mean variables, is the variable value at particular location I, Xj is the variable value at another location j, and Wij is a weight indexing location of I relative to j. in Morans I range, a strong negative spatial autocorrelation is in the range of -1 and a strong positive autocorrelation is in the range +1. The value 0 means it is spatially random pattern. 2.3.2 Distance Analysis The Average Nearest Neighbour (ANN) is one of the techniques for point distance analysis. It was used to analyzed the distance between each point, to determine whether the point pattern is clustered, random or regular (Clark Evans, 1994). In this study, the ANN was tested to predict whether the dengue incidence is cluster or not. The ANN analysis predicts the distance between each feature centroid and its nearest neighbour centroid. If the average distance is less than 1, the point pattern was considered clustered whereas if the average distance is greater than 1, the point was considered dispersed. The average nearest method is computed by: (1) Where is the observed average distance between each feature and their nearest neighbour. is the expected average distance for features given a random pattern. The average neighbour analysis also can produce the ZANN score, which indicates the likehood that the pattern could be a result of random chance. The ZANN score is computed by: (2) Where: (3) 2.3.3 Buffer analysis Buffering is a system operation that generates zones that consist of area within the specific distance with selected features (Chang, 2010). In this study, buffering was conducted to determine the extended neighbouring buffering method is used. The 500 meter radius of buffer were carried out from the dengue disease cases point as the mosquitoes flies at the maximum distance of 600 meter from the breeding site (Madanayake et al.,2010). A study conducted by de Freitas and de Olivera (2009) found that 50%-90% of female A. Aegypti flew up to 350 meter and 500.2 meter and their maximum displacement was 690 meter. 2.3.4 Hot Spot Prediction The Kernel density estimation interpolation was used to predict the hot spot locality (Jeefoo et al., 2011). Kernel density estimation is one of the method that applied to identify high risk areas within point patterns of disease incidence and also can defines the level of the high risk of that area (Bithell, 1990). Kernel density estimation is an interpolation that compatible for single point locality. The Kernel density estimation is the better hot spot identifier than cluster analysis. It can measures the density of point feature in each of the output raster cell .This method has been applied in previous study on spatial mapping on dengue disease to locate hot spot for dengue cases in the district of Hulu Langat (Er et al., 2010). Jeefoo et al, (2011) has used the kernel density to locate the spatio-temporal diffusion of dengue pattern and prove that the hot spot area have an influence on the spread of an infectious disease. RESULTS AND DISCUSSION 3.1. annual Dengue incidence years (2005-2011). During the study time, dengue cases (Fig. 1) increased from 37 cases were reported in year 2006 to 75 cases reported in 2009, after which, annual reported dengue cases have amplified alongside greater temperature and humidity alongside record of 52 cases in year 2008 and peaked in year 2005 alongside 159 cases. The incidence next cut to 40 cases in 2007 and resurged in 2011 alongside 48 cases. In the study period the highest dengue cases were described in August of year 2010 with 44 cases. The extremely months with high dengue occurrence were between July December. Results obtained in this discover are given in tables 1 to 4, and figures 1 to 12. Tables contain results for correlation of dengue occurrences alongside meteorological conditions parameters. While, figures show relationship between weather factors and dengue cases. reveals period sequence of weekly meteorological conditions predictors and dengue cases. Singapore experienced the highest weekly mean temperature of 30.48C in year 2005 followed by 30.38C in year 2002. The highest weekly mean temperature in the discover era was recorded in week 17 of year 2005 alongside zero weekly cumulative precipitation. As the most extended dry spell of 40 dates transpired in the early two months of 2005, highest weekly cumulative precipitation was recorded as 388 mm in week 51 of year 2006. Overall, weekly mean temperature for year 2000-2003 fluctuated from 25.7 to 30.38C; as the scope was 25.530.48C for 20042007. Concurrently, weekly cumulative rain in years 20002003 fluctuated from 0 to 260 mm alongside average 42 mm and the scope was 0388 mm alongside average 44.5 mm for years 20042007. Our results of this study indicates that precipitation and temperature were positively associated with monthly dengue cases informed in University Putra Malaysia (Table 1) which mean they seems to have played an important role in increase of dengue cases . Although, humidity hazy days and foggy days were have suspicious association with dengue cases occurrence but still not powerful as other parameters. 3.2 Correlation and Regression coefficients. Both Humidity and Temperature display positive role in cases number and the humidity shows suspicious response with high significant effect (P-value Correlation results are very significant in relation to mean maximum temperature (P-value = 0.860) and dengue occurrences. It is clear that rainfall associated with dengue cases (R ² = 85.5) which mean 85.5 % rainfall associate with dengue cases. In particular mean median humidity seems to have moderate positive role in dengue transmission compared to the other variables with (P-value = 0.779) and (R ² = 60.7) Figure 1, simplify rainfall amount for year 2006, shows that the precipitation playing very strong contributor factor for increase and decrease of dengue cases, while box plot confirms table 1 results (p-value) which is represents the percentage of total rainfall vs. dengue occurrence. Even though rainfall scale has increased over the last seven decades precipitation does show statistically significant (r square = 92.0 and p- value = 0.970). As shown in Fig. 2, dengue rate has increased linearly with monthly mean temperature at January and December with 7 and 6 cases as temperature increasing; plot confirms that temperature is participating factor of transmission of dengue virus owing to the positive relationship between temperature and dengue cases . Simplify relationship between humidity and dengue cases. As Fig3 illustrated humidity play doubtful contributor of increasing dengue diseases occurrence. From 70.1 % to 71.1% only one case has been recorded, while percentage of fogy months increased cases of dengue rises instantly. At 74.1 per cent 4 cases were informed and 7 dengue cases when humidity reached 76.3%. CONCLUSION The weather factors that affected the rising of dengue disease incidence have been identified, which were the temperature and humidity and rainfall. The study showed that the most weather conditions factors which contributed to the high incidence of dengue cases within UNIVERSITI PUTRA MALAYSIA area among seven years 2005-2011 were rainfall and temperature which were have very strong correlation with dengue cases. The result of the graphs plot shows that the three studied weather elements where positively associated with increase of dengue cases among students of UNIVERSITI PUTRA MALAYSIA area and The data presented in this study are important because it give baseline information on the main factors contributed of transmitting dengue virus for a particular zone. It is recommended that collecting forecasting data for the three specific factors to predict potential future cases to make efficient plan to control dengue transmission in case of epidemic and expect the number of dengue occurrence. When these strategies are implemented, the diverse costs associated with dengue cases will decrease. All of these results should be considered in the future patterns prediction of dengue transmission. Early warnings of dengue epidemics based on climate information are effectively communicated to public health decision makers and Climate accounts for some variation in dengue risk, Important to account for confounding factors. For future work incorporate better understanding of disease transmission process. The lack of information about specific factors which playing main role of high dengue disease incidence will lead to improper Vector surveillance and control management in case of dengue outbreak in specific zone and may loss many of lives. Understand connection between weather and dengue transmission will develop capability of national dengue management and diagnostic and impacts assessment of dengue mosquito vectors. The spatial distribution of dengue incidence within Kuantan district for 2011 has been mapped included geographic distribution and gender distribution. The geographic distribution has shown the highest distribution of dengue cases in Kuantan. The gender distribution has revealed that male population has the higher incidence of dengue cases. The buffer analysis was conducted to see the most high risk area for dengue fever incidence. It was identified that the high risk area were 500 meter radius from the dengue cases incidence. By using the statistical analysis, the pattern of spatial distribution of dengue incidence can be determined by spatial autocorrelation and was supported by distance analysis. The hot spot locations for dengue incidence were located by using kernel density estimation. As a conclusion, the Geographic Information System (GIS) provided a very useful tool in the health mapping. Furthermore, the GIS has played an important tool for effective surveillance and prediction of the dengue outbreak in order to reduce the number of dengue cases.

Dorothy Day- Short Biography :: essays research papers fc

Dorothy Day (1897-1980)   Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  Born in Brooklyn, New York on November 8th, 1897 Dorthy Day was a very influential person in the catholic economic lifestyle. Her father, John Day was out of work when she was little, which gave her empathy for other then, and later on in life because she also knows what its like to be there. When she moved to Chicago her life turned for the better, Her father became sports editor of a major Chicago newspaper. In 1914 she recieved a scholarship for the university of Illinois in Urbana. She wasent very social in school, keeping mostly to herself. Two years later she dropped out to move to new yourk and become a newspaper reporter. In 1917 she was arrested for protesting womens exclusion from the electorate outside the capitol and was thrown into prison only to be released soon after. This was first of many arrests in Dorothys future.   Ã‚  Ã‚  Ã‚  Ã‚  As a child Dorothy went to an Episcopical Church from time to time. She also attended St.Josephs in New York sometimes, but definatley not regularly.She was really interested in the catholic church and what it had to offer but she really didnt know much about it. She had a few catholic friends who she hung out with and stuff during college and afterwards.   Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  When she had a kid named Tamar, she decided to make her a catholic. She had Tamar baptised and then she herself was baptised, deciding to devote her life to good things. She met Peter Maurin wheo was twenty years older and was an experienced forrmer catholic brother. They talked and listened, and Peter said Dorothy should start a paper to publish all her ideas and stuff. So she took his advice and went and bought a printing press and set it up in her kitchen. She charged a penny for a copy and called it The Catholic Worker. Everyone loved it, and after a while homeles people started to show up at the door. Because of the writings in the paper the wanted to stay with Dorothy and Peter and of course they let them stay. So many people came to stay they opened up these houses all around the country to provide

The Cyclooxygenase-2 Essay -- Health, Diseases

The cyclooxygenase-2 (COX-2) is a key enzyme in the conversion of arachidonic acid to prostaglandins, which promote cell proliferation, angiogenesis and metastasis, and inhibit apoptosis. Unlike COX-1, which is constitutively expressed isoform, COX-2 is an inducible isoform of cyclooxygenase and which may participate in inflammatory responses and contribute to inflammation and cancersthe development of colorectal cancer as well as other human cancers (1). COX-2 is not detectable detected in most normal tissues. However, it but is rapidly induced when stimulated by in response to mitogens, cytokines and tumor promoters, which leads to the leading to increased accumulation of prostanoids in neoplastic and inflamed tissues (2). COX-2 is highly expressed at high levels in intestinal tumors in rodents and humans (1). For example, Mmore than 80% of all colorectal tumors were shown to overexpress COX-2 (3-5). Epidemiologic studies have shown that taking aspirin or other nonsteroidal anti-i nflammatory drugs on a regular basis could reduce mortality from colorectal cancer by 40-50% compared with those who not taking these drugs (1). One characteristic shared by all of these drugs is their ability to inhibit COX activity and/or expression (1). Although COX-2 is expressed in 80-90% of human colon carcinoma specimens, not all colorectal cancer cell lines constitutively expressed COX-2. Constitutive expression of COX-2 was only detected in a relatively small number of established colorectal carcinoma cell lines (6). For example, human colon adenocarcinoma cell lines, HCT116 and SW480, have been described as COX-2 negative, since they did not express COX-2, neither at mRNA nor at protein level (7). COX-2-derived prostaglandin E2 (PGE2) ... ...t as well as when the conditioned medium will be collected, with multiple parameters in which not only COX-2 mRNA and protein as well as PGE2 levels will be observed, but also other relevant molecular markers or factors like those mentioned above. Not only paradoxical observations of COX-2 expression and the functional activity in human colon cancer cell line have been documented, the role of PGE2 on inflammation seems also paradoxical. Although PGE2 is a potent mediator of inflammation (55), it was suggested that PGE2, endogenous COX products, also inhibit acute allergic inflammation (56). Thus, PGE2 may produce both pro- and anti-inflammatory effects (57). More extensive well-designed experiments are needed to help us to unveil the secret of COX-2 expression and the functional activity as well as their roles in physiological and pathophysiological conditions.

Cognitive competence is defined as the ability to perform adequately those cognitively complex tasks considered essential for living on one's own in this society. Willis SL. (1996). Everyday cognitive competence in elderly persons: conceptual issues and empirical findings, Oct;36(5):595-601) 2. The ability to develop and apply the cognitive skills of self-talk, the reading and interpretation of social cues, using steps for problem-solving and decision making, understanding the perspective of others, understanding behavioral norms, a positive attit ude towards life, and self –awareness. (The W. T. Grant Consortium on the School-Based Promotion of Social Competence (1992: 136)) 3. Academic and intellectual achievement. include the ability to use logic, analytic thinking, and abstract reasoning) (Catalano, R. F. , Berglund, M. L. , Ryan, J. A. M. , Lonczak, H. S. , ; Hawkins, J. D. (2002). Positive youth development in the United States: Research findings on evaluations of positive youth development programs. Prevention and Treatment, 5 (15), 1-106. ) This three definitions are little bit different. The third one is too narrow as it just mentioned academic and intellectual achievement. The second one, on the other hand, is not specific enough. In my understanding, I think cognitive competence is best defined using the first two definitions. Cognitive competence is defined as the ability to perform adequately those cognitively complex tasks considered essential for living on one's own in this society. It also includes unde rstanding the perspective of others, understanding behavioral norms, and self –awareness. † Theory Hui & Sun’s model (2007) This model divides cognitive competence into three types of thinking: 1. Creative thinking, a way of looking at problems or situations from a fresh perspective that suggests unorthodox solutions (which may look unsettling at first). 2. Critical thinking, which includes reasoning, making references, self-reflection, and coordination of multiple views. Critical thinking has been described as â€Å"the process of purposeful, self-regulatory judgment, which uses reasoned consideration to evidence, context, conceptualizations, methods, and criteria. † (Facione, Peter A. Critical Thinking: What It is and Why It Counts, Insightassessment. com) 3. Rational thinking refers to logical or reasoning being involved in the thought process. It refers to providing reasons or rational behind thoughts or ideas. It adds an element of calculation and planning to a steam of thoughts rather than basing them on emotion or personal opinion. It is a kind of objective process of thinking and an analytic approach to any problem. Rational thinking is based on reasons or facts and is hence much more calculating and realistic. Geiwitz’s model This model divides cognitive competence into three steps of thinking: 1. Know what, to know what is the problem 2. Know how, to know how the problem can be solved 3. Know why, to know why choose particular method to solve the problem, or to evaluate the method currently used. What How Why In Hui and Sun’s model, creative thinking is the innovative way of thinking. It allows people to invent new things or idea. Critical thinking is used when commenting on something, e. g. in writing editorials. As for rational thinking, it is used when analyzing. In my opinion, the second model is easier to understand. And it shows progressive levels of cognitive competence, whereas the first model only divides our thinking into three different ways. Therefore, I would further explain cognitive competence using the second model for reference. Take the example of inventors of the world’s first airplane – the Wright brothers, Orville and Wilbur. This is an good example to illustrate the concept of cognitive competence and the Geiwitz’s model. Applying the Geiwitz’s model, the Wright brothers’ aim was to create a â€Å"flying machine†, this is the â€Å"know what† level of cognitive competence. They then started to think and design this machine, and this is the â€Å"know how† level of cognitive competence. Finally they evaluated the products (what’s good and not good about it) and thought how to improve further. The â€Å"know how† and â€Å"know why† steps repeated. And finally an mature airplane was invented. Start Know what: to invent a flying machine Know how: How to built a better flying machine Know why: Why this model is good/not good enough Repeat A satisfatory model is invented Another example to illustrate is the development in high jump styles. The styles used in high-jumping has changed from initially scissors style, to straddle style, and finally the Fosbury style which is still using nowadays. Start Know what: to jump high Know how: What jumping style Know why: Why this style is good/not good enough Repeat A satisfatory syle is invented Factors affecting cognitive competence I think the factors affecting the development of one’s cognitive competence can be divided into intrinsic factors and extrinsic factors. Intrinsic factors are those confine to yourself, while extrinsic factors are those influenced by the environment. For intrinsic factors, I think there are: intelligence, personalities, knowledge and past experience. For intelligent, I think it is not difficult to imagine that it is important for high cognitive competence. Intelligence is particularly important for the â€Å"know how† and â€Å"know why† stage. Only if you are wise enough can you think of a new way to solve problem that no one has ever think of or find out what is the problem of existing method being used by other people. Moreover, intelligence is kind of inborn; therefore, cognitive competence is also inborn to a certain extent. As for personality, I think people with different personality may affect his/her performance in problem solving and the presentation of his cognitive competence. For example, if a person lacks confidence and likes to deal with problem in a low risk aspect, he/she may not abandon the existing widely used method to tackle the problem and use new methods even though he is clever enough to think of many other new potential methods. They may only attempt the new ways when they are 100% more effective and safer than the existing ones. Knowledge and past experience are very similar. They both can be regarded as memory. They are very important factors that affect cognitive competence. When tackling problems, memory always acts as your â€Å"reference†, it gives you basic information and background about the problem. And help you to figure out the solution in relation to this â€Å"reference†. Like the case of the Wright brothers, when they tried to invent a flying machine, their knowledge in engineering gives them basic information of how to build it. It is interesting to notice that sometimes past experience may hinder our cognitive performance. For example, when you are dealing with a project you are very familiar with, you might too much into your experience and knowledge and think that it is impossible to explore new methods. For extrinsic factors, there are: Environment (e. g. family background, situation of the problem) and the nature of problem Environment is the major extrinsic factor affecting one’s cognitive competence. It determines many of intrinsic factors including past experience, knowledge and even personality. Environment can also affects ones attitude to deal with the problem, thus performance of cognitive competence. For example, the due date of your proposal is tomorrow morning and now is already three o’clock in the morning and you haven’t even started yet. I am sure you may feel desperate and will not spend much time to think of the new ideas. Moreover, family socialization also affects cognitive competence and intelligence of people. (Grundmann, M. ; Teo, Thomas; Socialization, intelligence, and cognitive competence (1997)) Another one is the nature of the problem. It determines one’s past experience and knowledge are useful or not. It is because the past experience and knowledge can not apply to all situation. Importance of cognitive competence in leadership Cognitive competence is important in leadership. A research points out that cognitive skills were found to be directly correlate with high-level of leadership performance in a MLE (Military Leadership Exercises) research. (Marshall-Mies et al. , 2000) Often included intelligence, general skills, crystallized skills (e. g. oral and written expression and comprehension), and creative or divergent thinking capacities are cognitive capabilities that should influence leadership performance. (Connelly, Gilbert, Zaccaro, Threlfall, Marks & Mumford, 2000). I also agree that cognitive competence is important in leadership. First of all, leader with higher level of cognitive competence can deal with different kinds of problems with his own way of thinking. That means they can find out his own most effective way to tackle the problem without copying others method. This gives the leader independency that he does not need to rely on others too much. It also gives them maturity that they can have their own way of thinking. Independency and maturity surely are the important factors of a leader. This makes people happy and feeling safe to follow you. Secondly, leader with high level of cognitive competence can have great contribution to the team. They can give out a lot of useful ideas that no one has thought of before. This already makes them the strongest ones or the most unique ones in the team. People would love to follow leaders which are stronger than them. Again, this makes them feel safe. Finally, leaders with high level of cognitive competence can have a clear mind and know what is wrong in the team. They know what the team should do (goal). And they evaluate the performance of the team, and find out what should be improved. That means they are not only using cognitive skills in problem solving, but also in team management. It is because â€Å"team management† itself is already a task. People with higher cognitive competence usually have higher IQ and are conflicts encountering (Heydenberk R. A. and Heydenberk W. R. , Increasing Meta-Cognitive Competence through Conflict Resolution(2005)) Ways to enhance the level of cognitive competence Before discussing how to enhance the level of cognitive competence, I think we should first identify what cannot be changed or be improved. They are called constrains. Through understanding what are the constrains, we can focus on what can and what should be improved. The constrains include family background, intelligence and personality. These factors are sort of fixed, or can only have little change. So, to raise the level of cognitive competence, I think it is effective that we try to learn as much as possible. This is to enhance our knowledge and enrich our experience. As mentioned, knowledge and past experience are two important factors affecting one’s cognitive ability. This is because they are our own sources of information about the problem being coped. We can make use of this information to find a way to solve the problem. We may not figure out any new method, at least we know how people deal with it previously. In Janet E, Et Al, The Role of metacognition in Problem Solving, four steps of thinking is also mentioned to guide people to solve problems. They are: 1. Identifying and defining the problem 2. Mentally representing the problem 3. Planning how to proceed 4. Evaluating what you know about your performance This way of thinking can help people to organized their thoughts, so that they can deal with the problem step by step. I think it is a quite useful way to improve cognitive performance because it makes people organized and focus on one job at a time. This prevents them from being interrupted from different sources. Furthermore, it helps people to think logically. Part 2 Self-reflection Hong Kong students are known to be a copycat. We are blamed to have low level of creativity and afraid to try new things. People always say that we just copy things from others or textbooks without digesting them. But I think it is not totally my case. I am not a stupid student. I used to be very creative in primary school. Others describe me as naughty. It is because all my creativity is used in inventing new ways to play tricks on my classmates. I remember one time I played a game in an activity class. My teacher ask my group to use a deck of playing cards to build a tower as high as we can. Then we started. Other groups are using the traditional method (see left). Obviously it requires high technique. Therefore they can only built towers with few floors high. But I figured out another method. I folded up two cards, turned them sideway to make two â€Å"L† shape walls, put them facing each other to make a square wall, on top of it I placed a flat card. And I repeated to do this. Of course, my team built the highest tower. But guess what happened next. My teacher told us that was against the rules. Playing cards are not supposed to be folded (She didn’t tell us before the game). We lose that competition at the end. I think, after this event, my creativity started to slowly bury in my heart deeply. When I recall this event, I discover one important thing. That is our creativity is often being restricted by our teachers, and our education system. Teachers set all the projects, homework with rules and restrictions, trying to make them easier to mark and compare. But this made our assignments all looking the same. Examination questions have all the model answers, this made our student the same person who can only memorize answers without digesting the questions and answer them in their own way. Not that I don’t have critical thinking and creativity. It is just because they have to be thrown away to survive in HK’s education system. Take the example of A-level exams, the curriculum is very tight that teachers even cannot have time to teach us all the topics included. How would I have time to individually explore all the topics taught? Instead, in order to get high grades in this exam, I spent most of the time on memorizing past paper’s model answers. I know it would not help my cognitive development, but getting into a good university is more important to me. I believe this is also the problem of many students. Now, when I am given a problem to solve, I still try my best to explore the alternatives. May be this is due to my personality. I just don’t like to be the same with others. I like to be unique. But I think I am not creative as I was small anymore. Apart from the reason about the restrictions set by teachers just discussed, another possible reason may be due to my own knowledge and experience. As I mentioned in part 1 of this report, knowledge and experience, although can help to solve your problem, they sometimes hinder your cognitive performance. Sometimes this happens to me. I just rely too much on the knowledge and experience, and cannot think out of the box. But the major reason is still because of the education system in HK. But in the university, a place to train student’s critical thinking and creativity, I think that this problem would become less severe. To improve my cognitive abilities, I think the best way is to train to have independent critical thinking. Don’t rely too much on knowledge from any sources and my own or others’ past experience. Always try my best to look for other possible alternatives. Although this might spend a lot more time and at the end there may not come up any new things. But I think the process can also help me to develop my cognitive skills. Although it might hinder my cognitive performance, I think it is still important to enrich my knowledge and broaden my horizon. This is because learning more can let me compare different theories and thus train my independent critical thinking. They are also my valuable first encountered source when any problem comes to me.
