Determination Of Homology Between The Arsenic Resistance Plasmids R45 And R773 In Escherichia Coli, Joshua T. Clark

Dissertations and Theses

The resistance transfer factor R45 from Escherichia coli confers inducible arsenate and arsenite resistance in that bacterium. The genes for these resistances were cloned into the EcoR1 - Sph1 multiple cloning site of PGEM3 Blue vector (Promega) to produce a 4.9 kilobase plasmid, pJC1. This recombinant plasmid, pJC1, conferred IPTG induced resistance to arsenite and arsenate. In addition, pJCl was tested for homology with the E. coli plasmid R773, which encodes for arsenic resistance in that bacterium as well.

Through DNA-DNA hybridization the arsenic resistance determinants of R45 and R773 were compared. Under stringent hybridization conditions, R45 demonstrated DNA sequence …

Boudica: An Illustrated Narrative, Robin A. Ator

Dissertations and Theses

I study painting and composition for its own sake, and in this program I am pursuing it from a narrative or pictorial stance, much as did earlier artists, and doing so in contemporary terms. Distinguished examples of illustrators could include such artists as Raphael, Michelangelo, Rembrandt and Rubens, and modern practitioners such as Wyeth and Baskin.

The illustrator needs not only control of his means, but also other qualities in addition to those of a studio painter. He needs an imagination that will allow portrayal of scenes and viewpoints that can't be arranged in a studio. The artist's memory and …

Spontaneous Coherent Pulsations In Standing-Wave Laser Oscillators, Lee W. Casperson

Electrical and Computer Engineering Faculty Publications and Presentations

Spontaneous pulsation phenomena in xenon lasers are now well known, and related effects have been observed with other laser types. Most theoretical analyses of such pulsations are formulated for unidirectional ring lasers, whereas most experiments involve standing-wave resonator geometries. Described here are rigorous semiclassical models governing the spontaneous pulsation instability in standing-wave laser oscillators. The standing-wave results are more complex and closer to experimental observations than the ring results for operation in the Lambdip region near line center.

John Chrysostom, On The Statues: A Study In Crisis Rhetoric, Douglas B. Radke

Dissertations and Theses

The name of John Chrysostom has historically been held in high esteem by the Christian Church. John was born, circa A.O. 350, in the Syrian city of Antioch. His rhetorical career led him to the apex of religious power as bishop of Constantinople. As a result of his verbal harangues of the political and religious leaders, he was sent into exile, where he died in A.O. 407. During his life time he was recognized both for his eloquence and his controversial style. Since the fifth century he has been remembered by the epitaph "Chrysostom," a tribute to his oratorical abilities, …

Identifying Pedophiles With The Mmpi, Margaret M. Seits

Dissertations and Theses

The present study investigated the validity of the Pe (Toobert, Bartelme, & Jones, 1959) and Sexual Deviancy (Marsh, Hilliard, & Liechti, 1955) subscales, developed from the MMPI, to determine if the scales would discriminate convicted sexual offenders from nonsexual offenders.

From 'The Help Of Grave And Modest Women' To 'The Care Of Men Of Sense': The Transition From Female Midwifery To Male Obstetrics In Early Modern England, Karen L. Smith Adams

Dissertations and Theses

Until the sixteenth century, childbirth in England was the exclusive domain of women and was orchestrated by the female midwife. By the end of the seventeenth century, university-educated and church-approved male physicians were systematically beginning to usurp the midwife's role in the lying-in room and to gradually assume authority and power over the process of childbirth. Ultimately doctor-dominated childbirth threatened, and in some places accomplished, the displacement of the midwife. No one factor was responsible for the shift in delivery room personnel nor was the transition from female midwives to male obstetricians a "natural" one. This thesis looks at three …

Residential Care Facilities: Resident Characteristics And Public Policy, Sharon Anice Baggett

Dissertations and Theses

Residential care is a rapidly growing form of housing and service provision for older adults. Residential care policy is defined by historical and cultural influences in social welfare and by the history of policy development and regulation in long term care, specifically for nursing homes. These influences have played a large role in the growing regulatory environment for residential care.

This study examines the characteristics of elderly residential care facility (RCF) residents and examines these through the lens of current state and federal regulations concerning the type of care given in these facilities. It is hypothesized that the lack of …

An Experiment Testing The Bolinger Principle To Teach Gerunds And Infinitives, Juliet Rosemarie Vawser

Dissertations and Theses

Gerunds and infinitives persist in being a major problem for students of English as a Second Language. Therefore, Bolinger's (1968) principle appeared to be an attractive alternative to teaching gerunds and infinitives as opposed to the usual way of list memorizing.

A group of 101 ESL learners ranging in the mid to upper intermediate level was randomly distributed among two groups--experimental and control. They were given three tests prior to the experiment and three tests after treatment. Both groups were given the same contextualized materials. However, the experimental group was taught gerunds and infinitives using the Bolinger principle whereas the …

A Comparison Of Three Methods For Measuring The Attenuation Provided By Insert-Type Hearing-Protective Devices, Lois Jeanne Gaier

Dissertations and Theses

To effectively implement an occupational hearing conservation program, employers must know the amount of attenuation (noise reduction) provided by the hearing protective devices used by their employees. Currently standardized test methods, performed under laboratory conditions, cannot be easily implemented in industrial settings, and previously proposed field methods have depended upon the use of special headphones which are not typically available in the workplace. These problems have led many occupational hearing conservationists to use standard audiometric headphones to evaluate the attenuation provided to employees using insert-type hearing-protective devices. There has, however, been little research into the validity of using standard audiometric …

Eeny, Meeny, Miny, Mo: Self And Close-Other Selection Of Personality Test Interpretations, Sheela Word

Dissertations and Theses

In a study investigating the ability of subjects and their close friends or relatives (close-others) to recognize subject personality test results under conditions which controlled for the Barnum effect, 64 male and female undergraduate psychology students were administered the California Psychological Inventory (CPI). Each subject later attempted to choose his or her own unidentified CPI profile from among three, and a close-other of the subject independently made the same selection. It was found that 57.81% of subjects and 45.31% of close others were able to correctly identify subject profiles; these results were significant at the .0001 and .05 levels respectively. …

Febrile Response And Activity In The Crayfish, Pacifasticus Leniusculus Trowbridgii, Kenneth A. Fletcher

Dissertations and Theses

Poikilothermic and endothermic animals demonstrate febrile response to infection with bacteria or to injection with endogenous pyrogen extract of Prostaglandin E₁. Febrile response is measured in endotherms as a relative change in metabolically achieved body temperature and in poikilotherms as an increase in selected temperatures relative to previously established preferred temperatures. Final preferendum change with environmental factors or associated physiological states.

Crayfish Pacifasticus leniusculus trowbridgii were injected with 0.2 ml suspension of alcohol-killed gram-negative Aeromonas hydrophila bacteria in 0.9% saline. Injections were into the coxopodite of the cheliped. The crayfish were monitored in an aquatic thermal gradient by …

The Unveiling, Elizabeth Heron

Dissertations and Theses

The method I use in creating abstract sculpture presented the question that became the subject of my Master's thesis. Only occasionally will I create from a pre-conceived concept. The sculptures evolve through a process of addition and subtraction of material to something that simply pleases me. This method, really no method at all, seemed contradictory to my original intentions. My artistic goals were purposeful; I wanted to create sculpture that would provoke a reaction first, not a judgment of features. I wanted the viewers emotional and psychological involvement to be the basis for content and meaning in the work.

A New General Purpose Systolic Array For Matrix Computations, Hai Van Dinh Le

Dissertations and Theses

In this thesis, we propose a new systolic architecture which is based on the Faddeev's algorithm. Because Faddeev's algorithm is inherently general purpose, our architecture is able to perform a wide class of matrix computations. And since the architecture is systolic based, it brings massive parallelism to all of its computations. As a result, many matrix operations including addition, multiplication, inversion, LU-decomposition, transpose, and solutions to linear systems of equations can now be performed extremely fast. In addition, our design introduces several concepts which are new to systolic architectures:

- It can be re-configured during run time to perform different …

Mmpi And The Juvenile Sex Offender Russell Funk, Russell Funk

Dissertations and Theses

This study examined the effectiveness of the MMPI in identifying juvenile sex offenders. This study examined the hypothesis that previously identified subscales of the MMPI (i.e., Toobert et al. (1959) Pe scale and Dolan (1986) Ic scale) could be used in discriminating juvenile sex offenders (n=l 02) (and subgroups of juvenile sex offenders i.e., pedophiles n=79, and incest perpetrators n=41) from a control group of 40 juvenile offenders who had been adjudicated for non-sex related crimes. The study yielded results which indicate that the Pe subscale was not effective in discriminating pedophiles from non-pedophile sex offenders or from the control …

Two Dimensional And Three Dimensional Path Planning In Robotics, Hyun Suk Kim

Dissertations and Theses

A methodology for 2D and 3D collision free path planning algorithm in a structured environment is presented. The isolated free convex areas are represented as a nodes in a graph, and a graph traversal strategy that dynamically allocates costs to graph path is used. Modification of the algorithm for small computational time and optimality is discussed. The 3D path planning is done in the three orthogonal two-dimensional projections of a 3D environment. Collision checking to increase the optimality for 3D paths is done in each of the three orthogonal two-dimensional subspaces.

Die Rolle Der Hexe In Den MäRchen Der BrüDer Grimm Und Ludwig Bechsteins, Karin Ulrike Herrmann

Dissertations and Theses

Fairy Tales have been an important part of peoples' cultural heritage since time immemorial. From a very early age on, children hear stories about witches, giants, dwarf's, and magicians which make up their first entry into the literary world. Only recently have scholars begun to research just how much influence these stories have on children and how they might have a different impact on girls than on boys. This thesis will investigate the world of fairy tales in relation to their historical context and their differing relevance for male and female readers. I will examine the fairy tales of the …

A Contextualized Grammar Proficiency Test Using Informal Spoken English, Sally Wellenbrock Hinrich

Dissertations and Theses

Intensive college-level ESL programs typically focus on building students' academic skills in English. Yet many ESL students leave the intensive programs only to find that they cannot sufficiently comprehend conversations with native English-speaking classmates or understand freshman-level lectures. While the students frequently perceive the problem as relating to the rapid speech tempo used by native speakers, an integral part of the comprehension problem is the pervasive use of modified forms of English, commonly called reductions, contractions, and assimilations.

The present research investigates whether comprehension of certain modified forms of spoken informal English can be used to measure students' level of …

Off-Axis Multimode Light Beam Propagation In Tapered Lenslike Media Including Those With Spatial Gain Or Loss Variation, Anthony Alan Tovar

Dissertations and Theses

The propagation of light beams in inhomogeneous dielectric media is considered. The derivation begins with first principles and remains general enough to include off-axis asymmetric multimode input beams in tapered lenslike media with spatial variations of gain or loss. The tapering of lenslike media leads to a number of important applications. A parabolic taper is proposed as a model for a heated axially stretched fiber taper, and beams in such media are fully characterized. Other models are proposed by the concatenation of a parabola with other taper functions.

Syntactic Complexity, Error And The Holistic Evaluation Of Esl Student Essays, John S. Sparks

Dissertations and Theses

This study was designed to test five hypotheses in order to answer the following general research questions: 1) Are measures of syntactic complexity valid indices of ESL writing quality as measured by the holistic rating of student essays? 2) Would a measure of frequency and seriousness of error reflect evaluators' perceptions of ESL writing quality?

The Study Of National Character In The Post War Era : The Work Of Erich Fromm, David Riesman, And David Potter, Adam Rittenberg

Dissertations and Theses

This thesis examines the study of national character through the work of the psychologist Erich Fromm, the sociologist David Riesman, and the historian David Potter. Above all Intend to provide a critical exegesis of the three thinkers will relate them to one another by discussing the Interconnections In their thought, beginning with Fromm's social psychological theory of character, turning to Riesman's theory of sociology and, finally, Potter's theory of American history. Each, I argue, must be studied in the context his time--above all the climate of horror and uncertainty at mid-century.
