A Comparison Of The Effects Of Two Exercise Programs On Children's Self-Concept, Locus Of Control, And Mood, Lynne Blanken Einhaus

Theses and Dissertations

The effects of two physical fitness programs on children's self-concept, locus of control and mood were investigated in this study. It was expected that children who participated in a vigorous running program would demonstrate reduced depression and anxiety but a more internal locus of control and an increase in self-concept than children in a routine exercise group.

Participants in the Running Group were three fifth grade classes of a public elementary school in Richmond, Virginia (N = 60). Participants in the Routine Exercise Group were three fifth grade classes from a comparable public elementary school in the same district (N …

The Relationship Between Oral Contraceptives And Intraepithelial Neoplasia Of The Uterine Cervix, Barbara Jeannette Fox

Theses and Dissertations

The purpose of this study was to determine the relationship between specific oral contraceptive use and cervical intraepithelial neoplasia (CIN), and to determine if duration of use and content of oral contraceptives were related to CIN. The hypotheses tested in this study were: (1) norgestrel-containing oral contraceptives are associated with more severe levels of CIN, and (2) longer duration of oral contraceptive use is associated with more severe CIN.

Data was collected from 52 clinical records of clients who attended a colposcopy clinic during a four month period. Clients included in the study were utilizing one of five specific oral …

Use Of An External Inhibition Procedure In The Treatment Of Spider Phobic Subjects, Jerome D. Gilmore

Theses and Dissertations

This research represented an extension of previous work on the therapeutic application of the external inhibition phenomenon, and sought to examine the effects of such a procedure on the verbal- cognitive, motoric, and physiological components of the anxiety response. To accomplish this, subjects were selected and treatment effects evaluated on the basis of changes elicited in each of the three response modalities by a specific fear stimulus, The relative effectiveness of the external inhibition treatment in modifying the multiple components of the anxiety response was examined by a comparison with procedures controlling for expectancy effects and repeated exposure to the …

A Comparison Of Spanish Language Proficiency As Related To Location And Length Of Stay In A Foreign Language Environment, Karen Minnette Dawson Mckenna

Theses and Dissertations

This study examined the relationship of Spanish language proficiency as related to location and length of stay in a foreign language environment. The participants took a Spanish diagnostic test that measures Spanish proficiency through grammar principles and then answered a questionnaire concerning their language learning experiences, location and length of stay in a Spanish language environment.
It was found that Spanish language proficiency increased with longer lengths of stay in the Spanish language environment. No conclusive data were found to support the hypothesis that those in one Spanish-speaking environment attain a higher language proficiency than those in another Spanish-speaking area. …

Thomas Mann's Doktor Faustus: The Synthesis Of Success And Failure In Adrian Leverkuhn's Struggle For Truth As It Is Found In His Use Of 12-Tone Music And In His Application Of The Music-Philosophical Theories Of Theodor Wiesengrund Adorno, James F. Gurney

Theses and Dissertations

The two powers of Adrian Leverkuhn's life's struggle in Thomas Mann's Doktor Faustus, his hunger for and failure to rationally obtain truth as well as his unabating truth-ignoring need for artistic production, eventually cause a tremendous dissonance within him which ultimately leads to his insanity. This struggle, though destined for dissonant failure, nevertheless becomes a successful expression of Leverkuhn's oneness both with all humanity's struggle for truth and with modern humanity's consciousness of its failure to find truth. Leverkuhn's lifelong struggle is best represented in the novel through Leverkuhn's musical compositions and in them, through his fictional development and use …

Personality, Sex, And The Neuropsychology Of Attention, Peter A. Williamson

Theses and Dissertations

The influences of sex and personality on attentional style were examined in two neuropsychological studies in which perfor mance and event-related potentials (ERP's) were employed. Pribram and McGuinness1 (1975) conceptions of Activation and Arousal were recast in a lateralized framework in which the former was seen as characteristic of left hemisphere function while the latter was identified more closely with the right hemisphere. Four equal groups of nine subjects were selected on the basis of sex and ex treme extraversion scores (I-E), while controlling for neuroticism, to participate in two lateralized attentional tasks. The first, a vigilance task designed to …

Annular Flow In A Low - Pressure Steam - Water System, Arnfinn Borch Lund

Theses and Dissertations

Two-phase annular flow is an important aspect of two- phase flow. Three different models, Ghosal, Wallis, and Levy models, were used to calculate the pressure drop in an nular two-phase flow. The calculated pressure drop was com pared with a set of experimental data. The pressure range of the data was 350 to 850 kPa. Steam quality varied from 4.0 to 52.7 percent, while the total mass flux varied from 245.4 to 2303.7 kg/m^,s.

The predictions of the Wallis model were found to agree best with the data. This model appears to be well developed with respect to the hydrodynamic …

Forecasting Grain Equipment Sales, Russel R. Campbell

Theses and Dissertations

The purpose of the study was to identify and discuss variables that have an effect on the sale of grain handling equipment. A case study format was used to present the analysis. The problem addressed in the study is the inability of the case study company to forecast sales. It was hypothesized that sales could be predicted using data from previous years. Multiple regression was preformed using two independent variables: the number of acres of corn harvested for grain, and the government loan rates for on farm storage facilities, with past sales of the company being the dependent variable. Other …

Test Task And Item Similarity Factors Affect Memory And Eye Movements During Picture Recognition, David Paul Lommen

Theses and Dissertations

The purpose of this study was to explore how recog nition memory for pictures and eye movements vary depend ing on the type of test and the nature of the "related" distractor items. Prior research suggested that manipula tion of test type and distractor similarity both influ ence recognition memory. The present study crossed test type and composition (kind of distractors) in a 2 X 2 design.

Forty-eight undergraduates viewed an input list of 58 scenic, color photographs of cityscapes and landscapes. The memory test was composed of 12 "Same Photo" items, each identical to input list photographs; 12 "Related" …

Stochastic Estimation Applied To The Land Speed Of Sound Record Attempt By A Rocket Car, David A. Reinholz

Theses and Dissertations

Optimal linear smoothing theory is applied to the data from the Speed of Sound record attempt of a three-wheeled rocket car on 17 December 1979. A forward-backward estimation method is used which employs a seven state forward-running extended Kalman filter and a Meditch-form backward recursive 'fixed-interval' smoothing algorithm. Data for this analysis is supplied by a longitudinal accelerometer mounted on the vehicle and tracking radar measurements of range, azimuth, and elevation. States of interest include two components of vehicle position and velocity, accelerometer time-correlated error, and radar range and azimuth bias errors. Two iterations of the forward-backward smoothing algorithm provide …

Two-Dimensional Computer Modeling Of Joints And Fractures In Continua, Royd R. Nelson

Theses and Dissertations

This thesis presents a numerical formulation which incorporates the effects of joints, cracks, and fractures into a mathematical mode used to in an existing finite element code. Two separate crack definitions were incorporated, one involving a discrete crack model, and the other a continuum approach defining a new material with regularly spaced joints. Several examples are also presented demonstrating the use of this capability.

Terrain, Climate, And Vegetation In The Badlands Of The Little Missouri River In North Dakota, Paula Himmelheber Lee

Theses and Dissertations

The climate of southwestern North Dakota is typical for the Great Plains of the central and west-central United States. The Rocky Mountains influence the climatic condi tions by providing an orographic obstacle to air circula tion. Statistical analysis through correlation and regres sion of 30 years of climatic data from southwestern North Dakota and nearby stations in South Dakota and Montana is consistent with climatic relationships that have been de fined by previous research. The influence of the Rocky Mountains is quantified through a variable that represents the linear distance from each weather station to the front range.

An Evaluation Of Bacterial Flagella Staining Procedures, Dan Dalan

Theses and Dissertations

Five currently used flagella stains and staining procedures have been studied and evaluated. A staining method that is simplest, most reliable, and highly reproducible, especially for beginning students and technicians has been assembled and recommended.

Four important variables necessary for successful flagella staining were stressed. These variables are: growth of organisms, smear pre paration, staining procedure, and reagent stability.

Two important procedures which are part of some, but not all of the flagella staining methods studied are strongly recommended. One is the practice of enclosing a smear with wax pencil and adding a known, constant volume of dye. An effective …

Cognitive Ability And Cognitive Style In The Comprehension And Expression Of Emotion, Carole H. Hayne

Theses and Dissertations

This research investigated the ability to comprehend and express affect by non-verbal means. Darwin (1872) suggested that the non-verbal communication of emotion had a biological basis. Hughlings-Jackson (1879) emphasized the relationship between cerebral functioning and the ability to communicate affect. Neuropsychological research suggests that a major neuronal network located in the right hemisphere supports non-verbal communication. The evidence indicates the localization of expressive skills in the anterior cortex and comprehensive skills in the posterior cortex.

In the present study 31 behavioral tasks comprised a scale to assess the ability to communicate affect by non-verbal means. The tasks assessed the comprehension …

Protecting The Medium-Sized Business Computer, Michael J. Doonan

Theses and Dissertations

Computers were first introduced into our lives in 1944, when the first one was designed and built for the Army. They were able to process simple information faster than man, allowing him to concentrate on more difficult problems. Progress came quickly and the first commercial use of the computer was in 1954.

Today, computers are recognized as having a tremendous influence on our daily lives. They have been successfully incorporated into almost every aspect of human endeavor.

Release Of Histone Lysine Methyltransferases From Rat Brain Chromatin By Nuclease Digestion, Dale V. Onisk

Theses and Dissertations

The histone lysine methyltransferases catalyze the transfer of methyl groups from S-adenosyl-L-methionine to specific ε-N-lysyl residues in the N-terminal regions of histones H3 and H4. These enzymes are located exclusively within the nucleus and are firmly bound to chromatin. The chromosomal bound enzymes do not methylate free or loosely bound histones. However, histones H3 and H4 associated within the nucleosomes are methylated.

The enzymes were extracted by limited digestion (12-16%) of chromosomal DNA from rapidly proliferating rat brain chromatin with micrococcal nuclease. The enzymes were further purified by gel filtration, ammonium sulfate fractionation and DEAE-cellulose chromatography. The histone methyltransferases were …

Argumentation In Romans 1-11, Mary Margaret Walker

Theses and Dissertations

This study addresses some of the problems of the Book of Romans in Koine Greek as a source text for a translation, particularly into non-Indo-European languages which do not share common cultural, grammatical or rhetorical conventions with the original audience for which Romans was written. A basic question broached was, "What is argumentation - as a discourse genre, as an act, as a pattern of grammatical reflexes?"

The discourse grammar model of Dr. R. E. Longacre was the main point of departure. Important secondary sources were the work of Teun A. van Dijk on macrostructure; the semantic structure analysis method …
