Many Nineteenth century writers experienced the withdrawal of God discussed by Miller in The Disappearance of God. Robert Browning and Charles Dickens present two examples of "Fra Lippo Lippi" and Great Expectations model effective alternatives to accepting God's absence. Conversely "Andrea del Sarto" accepts the void the other two heroes shun.

This thesis investigates various theorems on polynomials over the rationals, algebraic numbers, algebraic integers, and quadratic fields. The material selected in this study is more of a number theoretical aspect than that of an algebraic structural aspect. Therefore, the topics of divisibility, unique factorization, prime numbers, and the roots of certain polynomials have been chosen for primary consideration.

Objectives were to: (1) assess toxicity of polychlorinated biphenyls on Eisenia foetida, in terms of survival (LC5O/LD5O), and suppression of coelomocytes to form secretory (SR) and erythrocyte rosettes (ER) with, and to phagocytize rabbit erythrocytes; and (2) compare results with those of Lumbricus terrestris to assess relative sensitivities to PCB. Using 5-d filter paper contact exposure protocol, LC50 and LD50 were 30.4 cg/cm2 and 4450 cg/g dry mass, respectively. Nominal PCB exposure concentrations of 5.0 and 10.0 pg/cm2 resulted in tissue levels of 1389 and 2895 pg/g dry mass causing a significant reduction in SR formation by 18 and 52%, respectively. ER formation and phagocytosis were reduced significantly (52 and 61%) only at the higher tissue concentration. Compared to reported data on lethality and immunomodulation in L. terrestris, E. foetida appears to be more resistant.

The evolution of the State was a process which went through many stages. Analysis of the modern State tends to begin with the Enlightenment; however, Dante Alighieri, Niccolo Machiavelli, and Martin Luther each represented early phases of this evolution. The theories of these men were closely tied to their evaluation of man's nature. Their main objectives were separation of the State from the Church and the definition of the rulers obligations to his subjects. Although humanism influenced all of them to varying degrees, each developed unique views of the State. Elements of these views can be detected in more modern theorists.

The purpose and scope of this paper is to discuss the emergence of the individual in the eleventh and twelfth centuries in light of the societal changes occurring at the time, and to establish the fact that this beginning of individualism can be seen particularly in the arts of the time. The evidence presented gives rise to the supposition that the society of the eleventh and twelfth centuries can be defined as humanistic, given that humanism implies a concern with and a concentration upon life on earth as opposed to life in heaven.

Although the graying of the American society has been well documented, the question as to whether the elderly populace will indeed become a political factor has yet to be determined. Some studies indicate that the elderly will soon develop the consensus needed for political action; other studies counter that the elderly will never be a viable political factor. Among the determinants listed as influencing the political participation equation are standard socioeconomic variables (e.g., race, social status, education, and income). These factors have been studied extensively (Campbell 1960; Key 1950; Milbrath 1965; Nagel 1987; Rose 1965). Trela recently added an item that could possibly influence the political activism of the elderly: membership in age-graded associations. This study addresses the questions raised by Trela (1971), namely, whether age-graded associations influence the political activity of senior citizens, and if so, in what direction elderly participation is swayed. Unlike previous reports, the preliminary data gathered for this study suggest that the age-graded associations of the elderly cannot accurately predict their political activism.

The primary purpose of this study was to determine the relationship between the effects of winning percentage and specific demographic data on the perceived burnout of varsity male head high school football coaches within the public secondary schools of Texas. Data were obtained from 226 varsity head high school football coaches during the 1990-1991 school year in Texas. Instruments used were the Maslach Burnout Inventory and a personal demographic data sheet. A one-way analysis of variance (ANOVA) and Pearson's product-moment correlation coefficient were used. Significance was set at .05. A relationship was found between burnout and career winning percentage, age, years as a coach, salary, coaching preparation, and school enrollment.

Duke Humphrey of Gloucester is often given credit for the renaissance of English learning in the fifteenth century. It is true that the donations of books he made to Oxford, his patronage of English and Italian writers, and his patronage of administrators who had humanist training resulted in the transmittal of humanist values to England. But is it also true that these accomplishments were mainly the by-product of his self-aggrandizing style, rather than a conscious effort on the duke's part to promote learning. The duke, however, does deserve recognition for what he unwittingly may have done.

The purpose of this study was to analyze the factor structure of items pertaining to health on the Minnesota Multiphasic Personality Inventory (MMPI2) for chronic back pain patients in comparison to a control group. The results may be used as groundwork for developing an MMPI2 subscale to describe this population. The groups differed in the sequence of the resulting factors and the percentage of variance accounted for by each factor. The factors extracted when evaluating the control group were titled in order: Poor Physical Health, Digestive Difficulties, Equilibrium, Depression/Malaise, and Multiple Somatic Complaints. Resulting factors for the pain group were: Depression/Malaise, Digestive Difficulties, Multiple Somatic Complaints, Headaches/Dizziness, and Neurological Reaction/Poor Physical Health.

The purpose of this study was to investigate the depiction of rainbows in the art of Frederic Church in relation to mid-nineteenth century scientific developments in order to determine Church's reliance on contemporary concerns with light and color. An examination of four Church paintings with rainbows, three oil sketches, and nearly a dozen pencil drawings shows that Church's rainbow art represents a response to mid-century cultural values connecting science and art. Changes within Church's rainbow depictions occurred as the artist explored the visual representations of light, synthesizing the scientific knowledge of light and color available to him, and reconciling that information with the requirements of art.

Little scholarly analysis has been devoted to the hypothesis that antebellum Texas women generally married within their own socioeconomic (slaveholding) class, and thus had only limited choice in the selection of marriage partners. This quantitatively based investigation suggests that the popular image should be carefully qualified. This study reveals that although a majority of Texas women who married during the early 1850s chose men who had the same slaveholding status, a significant minority crossed class lines. By using marriage records of the period in correlation with information gleaned from the census, conclusions were reached. Contemporary women's diaries, letters and reminiscences were investigated, in addition to a historiography of marriage in the South, which created the background for this study.

A powerful and efficient algorithm has been designed to deal with the critical timing problem of the MIDI messages. This algorithm can convert note events stored in a natural way to MIDI messages dynamically. Only limited memory space (the buffer) is required to finish the conversion work, and the size of the buffer is independent of the size of the original sequence (notes). This algorithm's real-time variable properties suggest not only the flexible real-time controls in the use of musical aspects, but also the expandability to interactive multi-media applications. A compositional environment called MusicSculptor has been implemented in terms of this algorithm.

ADP-ribose polymer metabolism has been studied in human cells derived from a patient with Glutamyl Ribose Phosphate Storage Disease (GRPSD) and in mouse C3H1OT1/2 cells following oxidative stress induced by hydrogen peroxide (H202 ). It has been postulated that GRPSD resulted from an abnormality in ADP-ribose polymer metabolism. This study has shown that these cells exhibit reduced poly(ADP ribose) polymerase activity which is proposed to result from modification of the enzyme with ribose phosphate groups. The modification in the polymerase is proposed to be secondary to a defect in either ADP-ribosyl proteinlyase or an overproduction of a cellular phosphodiesterase. The metabolism of ADP-ribose polymers was rapidly altered by H202 and there were independent effects on adenine nucleotide pools. The results suggest that ADP-ribose polymer metabolism is involved in cellular defenses to oxidative stress.

From the television advertisements made by presidential candidates from 1952 to 1976, this study analyzed the 131 advertisements that contained women. The analysis used the following descriptors: Number of Women's Roles, Age, Occupation, Marital Status, Locale, Concerns, and Status Relative to the Candidate. The results indicate that women are most likely to be shown as physically present although not speaking, in the 18 to 30 age group, belonging to a non-business atmosphere yet outside the home, and of an unknown marital status, and will not be shown in the same frame as the candidate. Womens' images in these advertisements were most commonly associated with issues involving the cost of living, taxes, pro-Nixon, and social security.

A description of the nature of the transition state structure for phosphoryl transfer in the cAPK reaction requires a measurement of the primary 180 isotope effect at the serine hydroxyl acceptor. Since it is difficult to obtain primary 180 isotope effect directly, the 15N/1 4N ratio of the a-amine of the C-terminal glycine in the peptide Leu Arg-Lys-Ala-Ser-Leu-Gly (when serine is phosphorylated) was used to represent on the phosphorylation at serine. 15N Glycine, ' 4N-Glycine and 180 serine were synthesized and used to synthesize two peptides, one containing 1 80-serine/' 5 N glycine and second 1 60-serine/1 4N-glycine. Methods were developed for hydrolyzing the peptides and quantitatively isolating glycine. Partitioning results suggest that catalytic rate was slow compare to substrate dissociation. The 180 primary isotope effect will be determined in the near future using the method developed herein.

Documentation of social impacts resulting from the construction of Lake Ray Roberts is to be incorporated into a two year post-impoundment study. Research objectives are to: 1) locate current residences of landowners and previous landowners who were displaced; 2) determine social impacts resulting from construction of Lake Ray Roberts; 3) document degree of satisfaction with current living conditions; 4) document landowners' degree of satisfaction associated with COE negotiations; 5) document landowners' observations. Landowners were identified by telephone and sent a mail-back questionnaire. Respondents were generally happy with current residences and communities. While courtesy and sufficient information were provided by the COE, respondents would have preferred for property settlements to be more consistent and timely.

The thesis speculates upon the source of Scriabin's pitch selection in several of his atonal works, concluding that Scriabin's "principle" stems from his own "mystic chord," its inversion at the major third, and the transposition of these two chords at the tritone. These four chords share the same invariant harmonic basis, Scriabin's characteristic French-sixth sonority. The quartet of chords combine to form two nine-note scales, each containing as a subset the octatonic scale. The thesis demonstrates how Scriabin composed his works in harmonic blocks, utilizing only the notes from these scales. The thesis traces Scriabin's atonal style back to his tonal period. His fascination with tritone adjacencies and relationships is discussed, and serves to support the theory. Other harmonic and linear theories are discussed. Also, the thesis shows how Scriabin used these scales structurally in his works.

Metabolic differences in the strategies used for pyrimidine base and nucleoside salvage were studied in the pseudomonads and enteric bacteria. Fluoro--analogs were used to select mutant strains of E. coli, S. typhimurium, P. putida, and P. aeruginosa blocked in one or more of the uracil and uridine salvage enzymes. HPLC analysis of cell-free extracts from wild-type and mutant strains examined the effectiveness of the selections. Evidence was found for cytidine kinase in Pseudomonas and for an activity that converted uracil compounds to cytosine compounds. Using media supplemented with 150 μg of orotic acid per ml, P. putida SOC 1, a Pyr, upp mutant which utilizes orotic acid as a pyrimidine source was isolated for the first time in any study.

This study analyzed the effects of estrogen replacement therapy (ERT), ethnicity, marital status, education level, maternal status and financial security on the perceived life satisfaction of women over fifty. Information was collected from 125 subjects at an independent school district. The instrument was adapted from a life satisfaction scale originally developed by B. Neugarten. Eight demographic items included ERT use, age, menopause status, marital status, educational level, ethnicity and perception of financial security. Statistical analysis consisting of one way analysis of variance, Student Newman-Keuls ad hoc procedure and multiple regression indicated an independent correlation between financial security and education level to life satisfaction scores. Neither ERT nor menopause status was correlated with perceived life satisfaction score of respondents.

Delphic Suite is a composition for orchestra that depicts specific events narrated in Homer's epic tale, Odyssey. For the purpose of this thesis the second movement, Raid on Ismarus, has been omitted so as to focus on the melodic, rhythmic, and harmonic structures of the first movement, Lament from Troy, and the third movement, Ruler of the Winds. Each of these musical parameters will be analyzed in order to illustrate the Suite's imitation of compositional techniques exemplified in the music of Homer's era, and the musical results obtained by juxtaposing those parameters upon a twentieth-century tonal scheme that provides the Suite with an eclectic ambience.

Small weight percentages of certain high-molecular weight polymers added to liquids in turbulent flow through conduits can result in dramatic friction reduction. Although many current and potential uses of the drag reduction phenomenon exist, there is a fundamental problem: drag reduction efficacy decreases rapidly with flow time due to the mechanical degradation in flow of the added polymer. In this thesis study, dilute aqueous solutions of polyacrylamide were tested under turbulent flow conditions in an attempt to determine where mechanical degradation in flow occurs.

The purpose of this study was to gain a better understanding of sexually aggressive behavior through the examination of humor appreciation among male undergraduates. As compared to nonaggressive males, sexually aggressive males showed a significantly greater appreciation for humor which negatively stereotyped females, portrayed prejudicial views of rape-and rape victims, and contained content related to male sex drive and virility. Differences in humor appreciation were also found for males with high sex drive. Additional findings included correlations between aggressive drive and sexually aggressive status, as well as between sex drive and likelihood to rape.

This study is concerned with the artistic use of classical rhetorical figures in Shakespeare's I Henry IV.After the Introduction, Chapter II examines the history of rhetoric, focusing on the use of the rhetorical figures in Ancient Greece, Ancient Rome, and Medieval Europe. Chapter III investigates rhetorical principles and uses of the rhetorical figures during the English Renaissance and examines the probable influence of rhetoric and the figures on William Shakespeare. Chapter IV discusses themes, characterization, structure, and language in I Henry IV and presents the contribution of the rhetorical figures to the drama's action and characterization. Chapter V considers the contribution of the figures to the major themes of I Henry IV and concludes that the figures, when used with other artistic elements, enhance meaning.

The purpose of the present study was to test a specific path model. It was hypothesized that the relationship between the impact (amount and valence) of stress and an outcome (expressing violence toward a partner) would be mediated by an individual's cognitive appraisal of stressful events. Multiple regression procedures were used to test the model. Standardized beta coefficients indicated the strength of the relationships among the variables. Significant findings indicated that the strength of specific relationships among the ten variables (impact of events, three types of primary appraisal, four types of secondary appraisal and the expression of threats and acts of physical violence toward a partner) differed depending upon subject sex and whether the impact of the events was perceived as positive or negative.
