Dissertations and Theses

This study investigated the following questions: 1) What is the spectra of human heart sounds when transmitted to the listener's ear through amplified and acoustic stethoscopes? 2) How does the acoustic spectrum of normal heart sounds compare to the threshold of audibility for normal hearing sensitivity? 3) Do normal hearing listeners elect to listen to heart sounds at a higher intensity than the acoustic stethoscope is able to transmit?

Correlation Of Preschoolers' Performance On Three Language Comprehension Tests, Alissa Clare Nordlund

Dissertations and Theses

The purpose of this study was to determine the relationship between the Peabody Picture Vocabulary Test-Revised, (PPVT-R) and receptive subtest of the Preschool Language Scale (PLS), and between the PPVT-R and the Test of Auditory Comprehension of Language-Revised (TACL-R), as well as determine how the tests compare in identifying children in need of further evaluation in the area of receptive language. The reasoning behind the goal of this study was to determine that if the three tests showed a strong, positive correlation and identified the same children as needing further assessment, then perhaps the test which was easier and …

A Model Of Suicidal Behavior In Latency Age Children Based On Developmental Object Relations Theory, Stephen Henry Michaelis

Dissertations and Theses

This thesis attempts to explicate the manifestation of suicidal behavior in latency age children based on developmental object relations theory. It asserts that the susceptibility to suicidal behavior becomes part of the child's developing ego organization during the first three years of life as the result of deviant or distorted emotional development. These disturbances interfere with the normal internalizing processes of the separation individuation phases, including the development of psychological mechanisms.

To accomplish the purpose of the study, the thesis generally classifies object relations theory within the parameters of developmental psychopathology and specifically classifies it as a component of contemporary …

Things Seen And Remembered, Charlien Dee Fitzpatrick

Dissertations and Theses

This thesis project consists of twenty oil paintings and watercolors. It is a series of visual problems based on work from direct observation as opposed to work from imagination. The concern is to show how the works from observed nature affect the imaginary pieces and how the imaginary works lend unexpected elements to the observed works. With a particular interest in color, visual energy, and painterly form, the project shows how these two avenues of exploration start out separately and eventually blend.

Urban Service Delivery System And Federal Government Bureaucracy: A Structural Analysis Of Spatial Distribution Of Water Supply In A Suburban Community Of Metropolitan Lagos, Michael Udochukwu Mbanaso

Dissertations and Theses

This study identifies the prevailing scarcity of urban public services and the conceptual relations among service delivery, patronage, bureaucratic activities and structural factors in the Lagos Metropolitan region. It examines the extent to which clientelism, bureaucratic decision rules and structural theoretical models explain water service delivery patterns in Festival Town (Festac), a suburb of Lagos, Nigeria.

The unprecedented pace of growth of the Lagos Metropolis since the mid-twentieth century gave rise to the spectacular spatial expansion of the continuous built up region. Urban industrial and governmental institutions have not kept pace with the population growth rate of Lagos. This demographic …

Women Of The Tudor Court, 1501-1568, Carol De Witte Bowles

Dissertations and Theses

Writing the history of Tudor women is a difficult task. "Women's lives from the 16th century can rarely be constructed except when these women have had influential connections with notable men.This is no less true for the court women of Tudor England than for other women of the time.

The purpose of this thesis is to discuss some of the more memorable court women of Tudor England who served the queens of Henry VIII, Mary I, and Elizabeth I, 2 and to determine what impact, if any, they had on their contemporary times and to evaluate their roles in Tudor …

An Analysis Of The Inhibitory Effects Of Linolenic Acid Upon Photosystem Ii Of Higher Plants, Mark Edward Iven

Dissertations and Theses

This study utilizes steady state fluorescence measurements, flash-induced P680+ absorption transients, and DCIP reduction kinetics to study the inhibitory effects of linolenic acid (LA) upon Photosystem II (PSII) in whole spinach chloroplasts and insideout wheat thylakoids. It confirms the presence within PSII of LA-induced inhibition of energy trapping and/or primary charge separation (i.e., primary inhibition), in addition to donor side inhibition. The latter is diminished in the presence of 1,5-Diphenylcarbohydrazide (DPC) and probably takes place at the oxygen evolving complex. Primary inhibition, which is more controversial, probably occurs between Ph and QA, with a likely contribution at the level of …

The Physiology And Biochemistry Of Isolated Skeletal Muscle Mitochondria : A Comparative Study, Mark Lowell Wagner

Dissertations and Theses

The physiological limit to maximum aerobic capacity (VO₂max) in vertebrates has been attributed to cardiovascular oxygen delivery, to the ability of the muscle cells to consume oxygen, or to a fine-tuned development of all components of the respiratory system such that no single component can be shown to limit VO₂max. The above hypotheses have each been developed using different experiments with different animals. The comparative studies uniting these animals and methods are limited. In order to further our knowledge of the cellular limit to VO₂max, skeletal muscle mitochondria were isolated from species representing four …

As a result, the commonalities and differences among female school administrators in Oregon are identified. Identifying the factors that relate to upward mobility of tenured and nontenured female administrators provides insight and hopefully will promote …

Factors Affecting Persistence Of Non-Traditional Students In A Non-Traditional Baccalaureate Degree Program, Dixie Lee Lund

Dissertations and Theses

Limited theoretical research exists regarding attrition of nontraditional (older, part-time, commuter) students on American college and university campuses today. Thus, when colleges or universities seek to improve programs specifically designed for such students, there is no broad research base on which to rely. The present study sought to determine if there were differences, especially ones the institution could do something about, between non-traditional students who left such a program and those who completed it. A conceptual model of non-traditional student attrition, developed by adult educators/researchers, Drs. John Bean and Barbara Metzner, provided the theoretical base for the study. Data were …

A Study Of Oxygen Precipitation In Heavily Doped Silicon, Robert Kurt Graupner

Dissertations and Theses

Gettering of impurities with oxygen precipitates is widely used during the fabrication of semiconductors to improve the performance and yield of the devices. Since the effectiveness of the gettering process is largely dependent on the initial interstitial oxygen concentration, accurate measurements of this parameter are of considerable importance. Measurements of interstitial oxygen following thermal cycles are required for development of semiconductor fabrication processes and for research into the mechanisms of oxygen precipitate nucleation and growth. Efforts by industrial associations have led to the development of standard procedures for the measurement of interstitial oxygen in wafers. However practical oxygen measurements often …
