Ignorance of the basic principles of music reading was one of the primary obstacles to the improvement of congregational singing in nineteenth-century America. Six separate numeral notation systems arose to provide a simple way for the common man to learn the basic principles of music. Hartley Day developed his own numeral notation system and published six tune-books that enjoyed modest success in the New England area. This thesis examines Day's numeral notation system as it appeared in the Boston Numeral Harmony (1845), and the One-Line Psalmist (1849). It also studies Day's periodical, The Musical Visitor, in which he continually attacked Lowell Mason, possibly leading to Mason's dismissal as Superintendent of Music of Boston's public schools.

Fifteen nonsmoking and fifteen smoking females 19 to 36 years of age were evaluated on measures of signal-to-noise ratio (SNR), jitter, shimmer, and speaking fundamental frequency (F0). The results indicated that: 1) there is a significant difference between female smokers and nonsmokers on measures of SNR, mean, and maximum F0 and, 2) there is no significant difference between female smokers and nonsmokers on measures of jitter, shimmer and minimum F0 . The SNR was found to be a powerful tool which is capable of distinguishing subtle vocal characteristics between the subject groups. It would appear that cigarette smoking may have an impact on the voice before distinct laryngeal pathologies are present.

Using the framework set up by rhetorical critic Thomas M. Lessl in his article "Heresy, Orthodoxy, And The Politics Of Science", this study examines the ways in which heretical discourse defines community boundaries and shapes perceptions of right belief. Specifically, this study analyzes the historic conflict in the Lutheran Church-Missouri Synod which produced the doctrinal statement "A Statement of Scriptural and Confessional Principles". Comparison is made between this event and other "heretical" conflicts in other discourse communities. This study concludes that community boundaries must be drawn, and that a doctrinal or policy statement is a useful rhetorical tool to accomplish such a task. Rhetorical critics may assist in this by examining heretical conflicts as historical trends, rather than emotional dissonance.

The problem of this study was to document the history of radio station WKY, Oklahoma City, and to locate its place within the development of American radio broadcasting. This thesis divides WKY's history into two periods: 1920 through 1925, the years it was operated by Earl Hull, and 1926 through 1989, after it was acquired by E. K. Gaylord. The purpose of this study was to record the history of the oldest radio station operating west of the Mississippi River, its effect on the broadcast industry in general, and its effect on Gaylord Broadcasting Corporation, the parent organization. The study also explored the innovations. in both programming and engineering that caused the station to grow into one of the most popular radio stations in the Southwest, as well as its decline in recent years.

The purpose of the present study was to evaluate the reliability of parallel-forms of the Comprehensive Neuropsychological Screening Device (CNS). Forty-five subjects ranging in age from 16 to 69 were administered Form A and Form B of the CNS at two week intervals. Results indicated that the CNS has adequate test-retest reliability. The results suggest the applicability of using the CNS as a screening device for brain dysfunction.

Two interviews were conducted with 20 participants from a Mental Health and Mental Retardation (MHMR) crisis house. Subjects were classified as good or poor premorbid level of functioning using a case history form and information from their social history charts. The study employed a self-narrative method to direct self disclosure. In the first interview, participants were asked to describe themselves. In the second interview they were asked to identify what they would change about their histories and to describe how this would make a difference in how their lives turned out. Support was not found for the hypothesis that those with the higher premorbid functioning would be better able to shift perspectives and use more positive self constructs. Methodological, theoretical and future research areas are discussed.

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.

The biosynthesis of pyrimidines in Pseudomonas putida was investigated. In this study, pyrimidine requiring mutants were isolated by conventional mutagenesis and enrichment. The strains required exogenously supplied pyrimidines for growth and were found by enzyme assays to be deficient for the product of the pyrB gene encoding the enzyme aspartate transcarbamoylase. None of the intermediates of the pathway could supply the auxotrophic requirement of the strain; only preformed pyrimidines, metabolized via salvage pathways could suffice. Pyrimidine limitation in the mutant caused a slight but significant fifty per cent increase in expression of all the de novo biosynthetic enzymes. Pyrimidine starvation's effect on nucleotide pool levels was examined in the mutant and caused a marked swelling of the purine nucleotide pools.

Research estimated toxicity of refuse-derived fuel fly ash (RDF-FA) on two earthworms species, Lumbricus terrestris and Eisenia foetida. Specific objectives were to: (1) Compare their 14-day LC50s under light and dark conditions; (2) separate toxicity due to osmotic, pH and physical factors from that of heavy metal contaminants; (3) compare relative differences of artificial soil and commercial soil as exposure media for evaluating toxicity to earthworms. The 14-d LC50s for L. terrestris in dark and light were 57.0 and 48.34 % RDF-FA, and 59.25 and 41.00 % RDF-FA for E. foetida using artificial soil. All of the toxicity resulted from heavy metals within the RDF-FA. Using L. terrestris, the LC50s for artificial soil and commercial soil were 52.30 and 64.34%.

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.

A method for assaying poly (ADP-ribose) polymerase (PADPRP) activity in lymphocytes of systemic lupus erythematosus (SLE) patients has been developed. Using this method, PADPRP activity has been studied in lymphocytes from 15 patients and 13 controls. The mean activity in SLE lymphocytes was significantly lower than that in controls and 60% of the SLE patients demonstrated activities below the minimum of the control population. Possible mechanisms for this altered metabolism were investigated. The Km app of PADPRP for NAD; size distribution, branch frequency, and rates of turnover of polymers; competition for substrate; and number of PADPRP molecules were studied. The data demonstrated that SLE lymphocytes have a decreased synthetic capacity rather than alterations in the substrate or in turnover of the product.

Sleep, emotions and pain are intimately connected, physiologically, by their location and utilization of the same brain centers and neurotransmitters. Sleep disturbances have been clinically observed in chronic pain populations; yet, no treatment program has formally addressed this aspect of patient care. It is hypothesized that a pain population (PN) will differ significantly from a non-injured workforce (WF) when reviewing quantitative and qualitative sleep data. This study strongly supports that sleep disturbances and socioeconomic decrements exist in chronic pain patients. Forty-seven variables were surveyed and 13 were found to show significant differences between the groups and seven were found to discriminate between the PN and WF groups at less than the .0001 level. A discriminant analysis was performed to determine the smallest model which could efficiently classify cases, according to successive root variables. The major discriminators are pain levels, medication, amount of sleep obtained and number of awakenings.

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.
