Looking For Literary Metaphor On Film: A Structuralist Study Of East Of Eden, Doctor Zhivago, And To Kill A Mockingbird, Charles D. Weaver

English Theses & Dissertations

A system based on existing research in semiotics and metaphor is developed and used to compare three novels with their film adaptations: East of Eden, Doctor Zhivago, and To Kill a Mockingbird. By grouping literary metaphors together in the novels, a subtext of meaning is revealed that can both aid in the understanding of the novel and serve as a tool for evaluating the faithfulness of the film adaptation. While none of the films studied completely followed this subtext, there were different levels of similarity between the novel and the visual metaphors used in the film. One reason for this …

A Comparative Analysis Of Pediatric And General Hospital Nurse Recruitment Practices, Rebecca Parsons Scott

Community & Environmental Health Theses & Dissertations

The focus of this study is a comparison of the National Association of Health Care Recruiter's annual recruitment survey with a duplicate survey that was sent to pediatriconly acute care hospitals. The goal was to determine differences between the recruitment and retention statistics found in all hospitals compared to those found in pediatriconly hospitals. Also, a major consideration was to find correlations among the variables in nurse recruitment and retention that might lead to a better understanding of what influences the recruitment budgeting process and how recruitment dollars might be spent most efficiently.

There was no significant difference found between …

Activation In Vitro Of Transfer Rna-Guanine Ribosyltransferase By Protein Kinase C, Panayota Eriotou

Chemistry & Biochemistry Theses & Dissertations

The purpose of this study was to isolate and purify the enzymes, transfer RNA-guanine ribosyltrasferase and protein kinase C, and to determine whether the phosphorylating enzyme activates the insertion enzyme in vitro. Transfer RNA-guanine ribosyltransferase lost activity within several days after isolation and total, complete reactivation was accomplished in the presence of protein kinase C. This demonstrated that ribosyltransferase's instability is related to the degree of its phosphorylation. It is proposed that modification of tRNA is controlled by protein kinase C. Deactivation of the insertion enzyme leads to hypomodified tRNA which in turn is associated with neoplasia. Potential use …

Integrated Control Of Thermally Distorted Large Space Antennas, Robert H. Tolson

Mechanical & Aerospace Engineering Theses & Dissertations

Studies on controlling the thermal distortion of large space antennae have generally investigated a single orbital position and have optimized actuator locations based on minimizing the RMS surface deviation from the original parabolic shape. One study showed the benefits of directly using far zone electric field characteristics as the performance measure; but, this approach resulted in a nonlinear programming problem. The objective of the current study is to develop an approach to designing a control system that (1) recognizes the time dependence of the distortion and (2) controls variables that are directly related to far field performance in a quadratic …

An Assessment Of The Utilization Of Permanent And Temporary Classrooms As It Relates To Cost And Efficiency In Selected School Divisions, E. Carlton Bowyer

Theses and Dissertations in Urban Services - Urban Education

In the mid-1900s there were over eighty thousand public school buildings in the United States housing approximately thirty-nine million pupils. Many were constructed thirty or forty years earlier and have approached the end of their useful life without requiring major retrofitting or replacement. Rising construction costs prompt school systems to investigate alternative means of housing rapidly growing student populations. This study traced the historical background of the school facility and the development of school construction relative to the function of education.

The focus of this study was to ascertain the current use of temporary and permanent housing in the fifty …

The Effectiveness Of Viscoelastic Damping Treatments On A Flexible Manipulator Subjected To Torsional Loads, Leah L. Remias

Mechanical & Aerospace Engineering Theses & Dissertations

The advent of new technology has led to an increasing number of missions in space. The space shuttle Remote Manipulator System (RMS) is a lightweight flexible manipulator currently used in NASA space missions. The future role of the RMS and similar flexible manipulators may include in-space construction and assembly tasks. Because these tasks require precise motion and short settling time of the end-point oscillations, effective vibration control schemes are being investigated.

Passive damping techniques have shown to provide a considerable amount of damping in controlling flexural vibrations. In this research passive damping via constrained viscoelastic damping treatments is explored as …

Development Of A Perturbation Generator For Vortex Stability Studies, John Edward Riester Jr.

Mechanical & Aerospace Engineering Theses & Dissertations

Theory predicts vortex instability when subjected to certain types of disturbances. It was desired to build a device which could introduce controlled velocity perturbations into a trailing line vortex in order to study the effects on stability. A perturbation generator has been designed and manufactured which can be attached to the center-body of an airfoil type vortex generator. Details of design tests and manufacturing of the perturbation generator are presented. The device produced controlled perturbations with frequencies in excess of 250 Hz. Preliminary testing and evaluation of the perturbation generator performance was conducted in a 4 inch cylindrical pipe. Observations …

Hydrogeology And Water Budget Analysis Of Two Interdunal Ponds Nags Head Woods Ecological Preserve, Dare County, North Carolina, Richard A. Hisert

OES Theses and Dissertations

Ground-water-fed interdunal ponds in Nags Head Woods Ecological Preserve lose as much as 7600 m³ yr^-1 of water through evaporation. This withdrawal of groundwater is sufficient to significantly alter flow patterns through the surficial aquifer on Bodie Island, N.C. Statistical analyses of evaporation estimates derived by various methods indicate a weak correlation, (r²=0.4-0.5) between pan evaporation data from Aurora, N.C. and pond evaporation at Nags Head Woods calculated by water budget analyses.

Results of stratigraphic and pedologic analyses in and around the ponds indicate that the ponds formed after development of multiple generations of dunes. This …

Trace Metals And Pyrite In Sediments Of Chesapeake Bay, Robert S. Kluckhohn

OES Theses and Dissertations

The formation and cycling of iron sulfides within anoxic sediments can affect the cycling of trace metals. The sediments at station CB-27 (near Annapolis, Maryland) in Chesapeake Bay were rich in FeS (39% of TS), low in greigite (3.6% of TS), and has a relatively constant pyrite concentration (50 - 60% of TS) with depth. The percent composition of total metals in pyrite were 25.7% cu, 11.8% Zn, 15.8% Fe, and non-detectable to 2.1% Cd. At Station CB- 28 (near the Choptank River), the sediments were low in FeS (1.7% of TS), richer in greigite (up to 14% of TS), …

Dynamics And Control Of Two Suspension Mechanisms For Ground-Based Testing Of Space Structures, Joseph E. Wilson

Two suspension systems which effectively simulate a gravity-free environment are presented. A single degree-of-freedom suspension system utilizing a specially profiled band mechanism in conjunction with a torsional spring is presented to show its feasibility and applicability for use as a ground-based testing device for flexible space structures. The second device, a two degree-of-freedom suspension system consisting of two springs and a folding linkage is presented to show the feasibility as a testing device for suspending space structures on earth.

Problems resulting in unwanted dynamic behavior due to deviations from the design parameters for both systems are addressed. A nonlinear controller …

From Aristotle To Ibm: Classical Rhetoric And The Teaching Of Technical Writing, Kathleen S. Scharf

English Theses & Dissertations

Over the past two decades, industry has placed increasing demands on higher education to produce students who can quickly adapt to a variety of writing situations. However, due to the relatively recent birth of technical writing as an academic discipline, technical-writing teachers tend to lack solid foundations on which to build their curricula. In their search for theoretical guidance, many teachers are turning to the classical rhetorical theories of Plato and Aristotle. Typically, teachers are applying Aristotle's notions of invention, arrangement, and style to the teaching of technical writing. Unfortunately, their approach tends to truncate Aristotle's five-canon system by deleting …

Interaction Between Amphetamine And Ethanol On Amphetamine-Produced Conditioned Place Preference, Cheryl Pelphrey-Weigand

Psychology Theses & Dissertations

Male Long-Evans rats were conditioned 6 days, alternating drug and non-drug conditions, using injections of .6 mg/kg d-amphetamine, amphetamine plus 60mg/kg ethanol, or amphetamine plus 120 mg/kg ethanol. These injections were given in a specific side of the shuttlebox to assess the development of a place preference or aversion. The amount of time spent in the drug-paired side was analyzed on 2 non-drugged test days. Rats spent significantly more time in the drug-paired side on Test Day 1 than on Test Day 2. When the ethanol groups were combined, these rats spent significantly more time in the drug-paired side than …

Relationship Of Dysphoria To The Recall Of Positive Negative And Neutral Words, Sarah Ellen Ware

Psychology Theses & Dissertations

This study investigated memory and cognitions in dysphoric and non-dysphoric individuals by examining reported thoughts and positive and negative word recall. Participants were female volunteers from Old Dominion University with 24 non-dysphoric subjects and 18 dysphoric subjects. Each subject was asked to read positive and negative life descriptions at separate times. After the descriptions had been read, 23 subjects were asked to suppress the description and 19 subjects were not given these instructions. Subjects then wrote down their thoughts for 6 minutes. Following the writing of thoughts, each subject was then asked to recall freely a list of 30 words. …

Measurement Of Thermal Noise In Condenser Microphones In A Vacuum-Isolation Vessel, Kim Chi Thi Ngo

Electrical & Computer Engineering Theses & Dissertations

The electrical noise generated by thermal agitation of the air molecules impinging upon the membrane of a condenser microphone and from its associated preamplifier has been studied analytically and experimentally over a wide bandwidth. These background noise levels constitute one of the most important specifications of a microphone for they determine the lowest sound pressure that can be detected. Therefore, a new method for measuring the thermal agitation noise within a bandwidth of 1-25600 Hz has been developed. The theoretical and experimental measurements of thermal agitation noise in a condenser microphone by enclosing the microphone in a vessel which is …

The Effects Of Two Polycyclic Aromatic Hydrocarbons Benzo[A]Pyrene And Naphthalene On Reproductive Success Embryological Development Larval Physiology And Mortality Of The Mud Crab Rhithropanopeus Harisii (Gould), Gregory V. White

OES Theses and Dissertations

Polycyclic aromatic hydrocarbons (PAHs) such as naphthalene (Nap) and benzo[a]pyrene (B[a]P) are common in the water column and sediments of estuarine and coastal areas. The mud crab Rhithropanopeus harrisii was exposed to varying concentrations of Nap or B[a]P to determine the effects on reproductive success, embryological development, larval physiology and mortality. Nap and B[a]P decreased hatching success and prolonged embryological development. Both pollutants produced high abnormality frequencies for egg exposed larvae. Molt frequency and respiratory rates of larvae from non-exposed eggs were more chronically affected by these pollutants than were egg exposed larvae. The EC₅₀ concentrations were determined for …

Optical And High Electric Field Effects In Bulk Gallium Arsenide Switches, Randy Roush

Electrical & Computer Engineering Theses & Dissertations

During the past few years, bulk, photoconductive switching has become recognized as a viable topic for future research on moderate and high power switches. The two-pulse, or BOSS, concept relies on an excitation laser pulse, and a separate de-excitation pulse in conjunction with silicon doped, copper compensated, GaAs to create a variable temporal electrical pulse width. The research contained in this document provides information concerning the feasibility of the BOSS concept, as the switch is scaled to larger sizes, and higher voltage and current. The major concern will be the high voltage and current effects. The absorption length for 1064 …

Root Biomass And Production In Four Communities Within The Great Dismal Swamp, Susan West Powell

Biological Sciences Theses & Dissertations

A biomass difference approach was used to measure biomass and production over eleven months in four different communities within the Great Dismal Swamp. On all sites, fine roots were the moat dynamic root component. Both biomass and production were highest on the mixed hardwood site, the least flooded site, and second highest on the cedar site, the site with the longest duration of saturation. The maple-gum and cypress sites had lower amounts of biomass and rates of production. Environmental parameters that influenced production included frequency and duration of flooding, density of the stand, and soil type.

A second method, an …

George F. Kennan And The Rebuilding Of Japan: The Second Phase Of Occupation Policy, Rhonda S. Beckham

History Theses & Dissertations

As head of the Policy Planning Staff of the Department of State, George F. Kennan had the opportunity to implement aspects of the containment policy which he had helped to create. In 1947, Japan became vital to United States national security interests in Asia but was threatened by Communist infiltration because of an unstable political and economic situation promulgated by the initial post-surrender policy immediately after the war. An investigation by Kennan led to the implementation of significant changes which were enumerated in a National Security Council Report. This thesis will examine Kennan's foreign policy philosophy, the containment theory, the …
