      • Love & Loneliness in Carson McCulleis Works : Particulary from her the Heart is a Lonely Hunter

        김영희 청주대학교 1981 국내석사

        RANK : 247471

        Carson McCullers,(Lula Carson Smith,(1917-1967)), born in Georgia, is one of the best authors in modern America. She belongs to the group of southern writers where southern fiction has been called the Gothic School because its contents are very grotesque and strange. I deal with Carson McCullers' first novel, The Heart Is a Lonely Hunter(1940), in this thesis. I think this fiction exemplifies her characteristic symbol of love and the loneliness of people, the main theme in her works. Specifically, I studied the relationship of love and loneliness, not merely the solitude, through John Singer and other characters. To work out her plots(theme) she uses two basic symbols, music and time. Also her use of physically deformed or psychologically warped characters represents a way of stressing the hopelessness of human plight. The two central figures of the story, the deaf-mutes, Singer and his friend, Antonapoulos, may be seen as embodiments of a general atrophy of communication in a wasteful, shortsighted society. The love that exists between these two, as between the other frustrated or disadvantaged "couples" who share some inner truth, becomes a form of liberalism from the social straightjacket. Carson McCullers thought every man has loneliness and anyone can't escape from it. So all her characters have reasons to be lonely even though the reasons differ from one another. But also the author said man doesn't want the situation of loneliness in his life, if possible, he searches for love to alleviate his loneliness. So her characters are seeking for love to escape their drab situations. So John Singer is surrounded by four disciples, with himself as the pivotal character. To love generates search for expression and spiritual integration with something greater than themselves. But because of their misplaced beliefs in Singer who Singer who loves Antonapoulos instead of them, the others are doomed to unrequited love. They never realize that Singer has a lover because he doesn't reveal his secret to anyone about Antonapoulos. In the relationships of them, Biff questions why everyone likes John Singer so deeply. At last he discovers the previous controlling role of Antonapoulos over Singer. Now that the Greek deaf-mute has gone, Singer assumes the controlling leadership of the group. Carson McCullers' theory of love is very unique. She stresses man loves everything and anything from lower to higher in his mind. Also she said love is a joint experience between two persons- but the fact that it is a joint experience does not mean that it is similar experience to the two people involved. There are the lover and the beloved, but these two not necessarlily the same. There is another kind of love, Biff's love for Mick. He thinks all things have dual sexuality so he has strong feelings of motherly love for her. McCullers never deals with normal romantic and erotic sex between male and female. The author uses the theme of anti-sex and pits both sexes in abnormal situations of life. So her love, broken or one-sided love, leads man into deeper loneliness. I dealed with love and loneliness of people separately in this thesis. But in fact, I think her theme is cause and effect each other, that is, everything has two-sides. Also her thought is suitable today as modern man continues to be lonely because society is too large to enable people to understand each other well. For these reasons, Carson McCullers is recognized as one of the best writers in modern America.

      • Individual and neighborhood socioeconomic status across the life course and subclinical atherosclerosis

        Carson, April Perry The University of North Carolina at Chapel Hill 2006 해외박사(DDOD)

        RANK : 247343

        Atherosclerosis is detectable very early in life, develops gradually as a subclinical condition over the life course, and contributes to the manifestation of clinical events. Parallel to the development of atherosclerosis, a host of socioeconomic status (SES) exposures and environments are experienced from childhood to adulthood, which may influence the atherosclerotic process. Yet, little is known about the association between SES and subclinical atherosclerosis. This study investigated the association between individual-level SES, neighborhood-level SES, and subclinical atherosclerosis [intima-media thickness (IMT), carotid plaque, and peripheral arterial disease (PAD)] among 12,332 participants in the Life Course Socioeconomic Status, Social Context and Cardiovascular Disease (LC-SES) Study (2001-2002). This study evaluated this relationship by first quantifying the association between individual-level and neighborhood-level cumulative SES and subclinical atherosclerosis and then the association between individual-level SES, neighborhood-level SES, and subclinical atherosclerosis at three time periods (childhood, young adulthood, and older adulthood) across the life course using multilevel analysis. In manuscript 1, lower individual-level cumulative SES across the life course was associated with a greater burden of subclinical atherosclerosis, as assessed by IMT and PAD, among middle-aged whites and African-Americans, while no association was apparent for carotid plaque. Lower neighborhood-level cumulative SES was also associated with subclinical atherosclerosis, although this association was no longer apparent after adjustment for individual-level SES. In manuscript 2, associations were found between SES over the life course, at both the individual-level and neighborhood-level, and subclinical atherosclerosis, but the SES measures and the magnitude of the associations differed by life epoch, and different associations were observed in African-Americans and whites. As cardiovascular disease (CVD) continues to be the leading cause of death in the United States, it is essential for research to explore the role of behavioral and environmental factors that are associated with subclinical measures of atherosclerosis to help identify avenues for the early prevention of CVD risk factors, development of vulnerable plaques, and the occurrence of clinical cardiovascular disease.

      • The preparation of fluorinated and water-soluble materials via heterogeneous polymerizations in carbon dioxide

        Carson, Terri Johnson The University of North Carolina at Chapel Hill 2000 해외박사(DDOD)

        RANK : 247343

        The use of carbon dioxide (CO<sub>2</sub>) as a polymerization medium offers numerous advantages over processes where organic solvents are employed. However, most hydrocarbon polymers have low solubility in CO<sub>2</sub> which necessitates the need for novel CO<sub>2</sub> amphiphiles. Atom transfer radical polymerization (ATRP) has been used in the synthesis of such materials. This process was performed using CO<sub>2</sub> as the reaction medium. The best results were achieved when a fluorinated ligand was applied to the system. Diblock and triblock copolymers were made incorporating fluorocarbon segments with either poly(dimethylaminoethyl methacrylate) (PDMAEMA) or poly(methyl methacrylate) (PMMA). The MMA ATRP dispersion process was also examined and resulted in the formation of spherical colloidal particles with controlled molecular weights and narrow polydispersities. Hydrophilic colloidal particles have also been made by several heterogeneous polymerizations in CO<sub>2</sub>. The dispersion polymerization of 1-vinyl-2-pyrrolidone (VP) in the presence of poly(1,1-dihydroperfluorooctyl acrylate) stabilizer resulted in the formation of nearly monodisperse spherical particles. This system was investigated as the stabilizer and VP concentration was varied and as the CO<sub>2</sub> pressure and reaction time changed. Temperature-sensitive colloidal particles based on poly(N-isopropyl acrylamide) (PNIPAAM) and poly(N-ethyl acrylamide) (PNEAM) were also prepared. These particles were produced by three different methods that include precipitation, dispersion, and suspension polymerizations in CO<sub>2</sub>. The particles range in size from 0.17 μm to slightly under 1 mm. Fluorocarbon polymers containing segments of PDMAEMA or a monomeric sugar moiety were used as stabilizers in these systems.

      • Fluvial responses to Holocene environmental change, Uinta Mountains, northeastern Utah

        Carson, Eric Christopher The University of Wisconsin - Madison 2003 해외박사(DDOD)

        RANK : 247343

        This research has shown that stream channels and streamflow in the Uinta Mountains of northeastern Utah are sensitive to climatic change, local geomorphology, and land use over timescales ranging from decadal to millennial. Analysis of U.S.G.S. annual duration flood series shows that magnitudes for annual flood peaks, when averaged for the Uinta Mountains gage sites, increased by 0.39 standard deviations for the period 1962 to 1998 compared to 1918 to 1961. This statistically significant break in the annual duration series agrees closely with a documented shift in the frequency and seasonality of El Niño-Southern Oscillation (ENSO) events recorded in hydrologic activity for other localities in the western United States. Evaluation and application of previously collected dendrochronologic data for the southern Uinta Mountains supports the idea that climate variations have been responsible for large temporal variation of streamflow over the past ∼350 years. For the reconstructed period A.D. 1637 to 1970, mean annual discharges on Ashley Creek exhibited statistically significant non-random clustering of values lower than the 10<super>th</super> percentile and greater than the 90<super> th</super> percentile of discharges. Quantitative reconstruction of former bankfull flood magnitudes based on morphologic dimensions of relict cut-off channels preserved in floodplains of the northern Uinta Mountains also indicate that shifts in climatic conditions have led to significant past episodic variations in magnitudes of high-frequency floods. Bankfull floods were 10 to 20% larger than modern from 1000 to 2800 cal yr BP and prior to 4600 cal yr BP, but were 10 to 15% smaller than modern from near present to 1000 cal yr BP and from 2800 to 4600 cal yr BP. Human-related activities have strongly influenced hydrologic processes since the late-19<super>th</super> century. For example, in the West Fork Black's Fork valley, overbank alluvial sedimentation since clear-cut logging in the late 19<super>th</super> and early 20<super>th</super> Centuries has contributed several centimeters of floodplain sedimentation whose specific local thickness is sensitive to local valley cross section morphometry. HEC-RAS modeling of floods of variable magnitudes indicates that local variations in valley cross section morphology strongly influence flood conveyance and floodplain sedimentation characteristics today and probably during past. Individual channels that are as old as 7080 ± 40 <super>14</super>C yr BP also exhibit evidence of colluvial and localized fluvial sedimentation. Radiocarbon ages from the Yellowstone River basin in the southern Uinta Mountains indicate that the deglaciation in the lower portion of the basin had begun by 9980 ± 100 <super>14</super>C yr BP, and was potentially occurring by ∼11,200 14C yr BP. Limiting radiocarbon ages from the headwaters of Yellowstone River within 1 km of the cirque headwall indicate deglaciation occurred by 7860 ± 60 <super>14</super>C yr BP (8550 to 8740 cal yr BP), and probably significantly earlier.

      • Region-based image querying and classification

        Carson, Charles Converse, Jr University of California, Berkeley 1999 해외박사(DDOD)

        RANK : 247343

        Retrieving images from large and varied collections using image content as a key is a challenging and important problem. While users would like to retrieve images containing particular <italic>objects</italic>, most current systems do not access the image at the level of regions that correspond to objects. In this thesis we present a framework for image retrieval based on automatically finding coherent regions of color and texture (“blobs”) and using the properties of these regions in order to perform image querying and classification. We have implemented a system which creates this “Blobworld” representation and uses it for user querying and automatic classification. We present experimental results indicating its performance on the general image retrieval task. Our segmentation algorithm is based on clustering pixels in a joint feature spare of color, texture, and position. We use the Expectation-Maximization algorithm to fit a mixture-of-Gaussians model to the pixel feature distribution. The results of the segmentation algorithm are quite good in most cases; the image regions generally correspond to objects or parts of objects. To each region we attach a description of its color, texture, and shape. We have constructed an interface for user querying. An important aspect of the system is that the user is allowed to view the internal representation of the submitted image and the query results. Similar systems do not offer the user this view into the workings of the system; consequently, query results from these systems can be inexplicable, despite the availability of knobs for adjusting the similarity metrics. We present results showing that queries for distinctive objects using Blobworld yield much higher precision than similar queries using global color and texture histograms. To facilitate queries in very large collections, we present techniques for indexing the Blobworld features in order to reduce the query time. Finally, we present results from a preliminary investigation into using the Blobworld representation to classify images automatically into a number of categories.
