    ... arsenic and toxicology are interested in the pending crisis in India because of the wealth of information to be gained. It would be possible to discover what diseases arsenic causes and the information learned could help countries such as Taiwan, Chile, and Mongolia, where there are large problems with arsenic contamination. (Bagla and Kaiser 1996) Response from the Indian government to the crisis is low. They had approved a project that costs $25 million in 1995 that would supply piped water to the Malda district, but there has been scant improvement. In fact, the problem has grown more widespread. Tube wells that were not previously contaminated are now tainted and the federal governme ...

  • A Rose For Emily - 1,067 words
    A Rose For Emily "A Rose for Emily" In "A Rose for Emily," William Faulkner's symbolic use of the "rose" is essential to the story's theme of Miss Emily's self-isolation. The rose is often a symbol of love, and portrays an everlasting beauty. The rose has been used for centuries to illustrate an everlasting type of love and faithfulness. Even when a rose dies, it is still held in high regard. Miss Emily's "rose" exists only within the story's title. Faulkner leaves the reader to interpret the rose's symbolic meaning. Miss Emily was denied the possibility of falling in love in her youth, so subsequently she isolated herself from the world and denied the existence of change. Miss Emily was den ...

    A Rose For Emily The Symbolism and Characterization in A Rose for Emily by William Faulkner In the short story A Rose for Emily by William Faulkner, the macabre ending is foreshadowed by the story's opening with Miss Emily Grierson's death and funeral.

Her life, like the house which decays around her, suffers from lack of genuine love and care. The author also uses characterization to reveal the character of Miss Emily. He expresses the content of her character through physical description, throug ...

It is a story of the conflict between the old and the new South, the past and the presentwith Emily and the things around her steadfastly representing the dying old traditions and the present expressed mostly through the words of the narrator but also through Homer Barron and the new board of aldermen.

  • Abortion Is A Subject Of Perception To Find A Clear Cut Solution Would Be To Commit Suicide Doctors Say That Candy Is Not Bad - 1,958 words
    Abortion is a subject of perception; to find a clear cut solution would be to commit suicide. Doctors say that candy is not bad, so long as there is not a consumption of it at one time. All things in life must be viewed through a reasonable, clear mind. To say abortion is good or bad is to look at it blindly. Abortion is not like racism or oppression where to look at one incident is to miss the point. Or if we look at the big picture we see the crime, and abuse. Abortion is by far a twentieth century invention or discovery, the only thing modern about abortions is the procedure. During the time of ancient Greece and Rome there have been writings of abortions. Abortions may be dangerous no, b ...

  • Compare The Awakening To Madame Bovary - 1,203 words
    Compare The Awakening to Madame Bovary Kate Chopin's The Awakening and Gustave Flaubert's Madame Bovary are both tales of women indignant with their domestic situations; the distinct differences between the two books can be found in the authors' unique tones. Both authors weave similar themes into their writings such as, the escape from the monotony of domestic life, dissatisfaction with marital expectations and suicide. References to "fate" abound throughout both works. In The Awakening, Chopin uses fate to represent the expectations of Edna Pontellier's aristocratic society. Flaubert uses "fate" to portray his characters' compulsive methods of dealing with their guilt and rejecting of pers ...

  • Fall Of Emily - 933 words
    Fall of Emily Life is fickle and most people will be a victim of circumstance and the times. Some people choose not to let circumstance rule them and, as they say, time waits for no man. Faulkners Emily did not have the individual confidence, or maybe self-esteem and self-worth, to believe that she could stand alone and succeed at life especially in the face of changing times. She had always been ruled by, and dependent on men to protect, defend and act for her. From her Father, through the manservant Tobe, to Homer Barron, her life was reliant on men. The few flashes of individuality showed her ability to rise to the occasion, to overcome her dependency, when the action was the only solutio ...
