Merlin Classifier System (open access)

Merlin Classifier System

There is a natural tendency for biological systems to change as their environments change. The fittest in the biological systems survive, adapt to their environment, and multiply while the weakest in the environment diminish. There have been attempts in computer science to model the processes of natural selection and survival which occur in biological systems in order to obtain more efficient and effective machine-learning algorithms. Genetic algorithms are the result of these attempts.

Transcendence and Paradox: A Question of Female and Male (open access)

Transcendence and Paradox: A Question of Female and Male

For the problem in lieu of thesis, a series of ten works were created in which a male image replaced the female image; I continued to utilize the same materials, format, and centralized frontal figure. A record of the work was accomplished by maintaining a written and visual journal on progress and outcome. Some research was made into topics related to the work, and the findings from the literature comprise chapter two of the paper. In executing this body of work and researching related topics, I hoped to better understand my conscious and unconscious processes and motivations in creating both the self-portrait series and the new series.

An Investigation of the Packaging and Display of Jewelry as Image and Concept (open access)

An Investigation of the Packaging and Display of Jewelry as Image and Concept

Just as packaging in its most mundane, pragmatic sense refers to the commercial and traditional aspects of jewelry, so also does display. In addition to being a mere vehicle for presentation, the idea of display creates an intriguing set of design and conceptual problems which seem to be a natural extension of my current and ongoing concerns.

Between Seeing and Knowing (open access)

Between Seeing and Knowing

I intended to create a body of work using a variety of media and a combination of imagery that is both subjective and objective in regards to representation. I incorporated into the work, words and phrases which are not related to the imagery. This has allowed the work to be variously interpreted. I wanted certain elements of the work to appear simultaneously very old and very new.

The Mutation of a Fiddler Crab (open access)

The Mutation of a Fiddler Crab

For a year I have tried to be as far away from painting (painting in a strict sense, i.e., two-dimensional, canvas, glazes, washes, etc., as possible. I successfully built a quality body of work that was formally sound and conceptually sophisticated, far surpassing my original "fiddler crab period." Now, having grown my other claw I wanted to approach painting in a comparative relation to my other body of work. Specifically, I wanted to show the valuable visual possibilities ready to be investigated in my paintings. For this reason I did not want to completely abandon painting, nor did I consider halting production of my three-dimensional pieces.

The Creation of New Metaphors Out of Symbols From the Past

In order to become more aware of valuable characteristics that may be unique to the paintings and/or the books, I proposed to execute a body of work consisting of four sets, each set containing one painting and one book. I continued using religious icons as subject matter and the motif of the layered pentimento of the fresco as a metaphor for self-investigation.

Owen Glendower and the Welsh Fight for Independence (open access)

Owen Glendower and the Welsh Fight for Independence

Owen Glendower led the last military struggle of the Welsh against the English crown for Welsh independence and nationalism. The failure of the Glendower rebellion established the supremacy of English rule over Wales. For six hundred years the status of Wales as a principality of the crown has not been seriously challenged. This paper will show how widespread the idea of "Welshness" was in 1400 and how much support existed for Wales as an independent nation. Welshmen sought to move from the status of a medieval, tribal principality to a position of an independent nation capable and ready to stand with other national in the world. The role of leadership that Owen Glendower assumed in the final rebellion against the English king, Henry IV, lifted him from a popular Welsh prince to an historical legend.

Organizational Commitment in a Self-Managing Work Team Environment (open access)

Organizational Commitment in a Self-Managing Work Team Environment

This study examines the determinants of organizational commitment in a self-managing work team setting. The data used in the study are from a sample of 313 employees in an electronics manufacturing plant. Chapter one introduces the reader to the topic of self-managing work teams and explains the relevance of commitment to this organizational structure. Chapter two is a review of the literature which focuses on commitment, its determinants, and two theories used to explain the relationship between them. The remaining chapters describe the methodology used in the study, explain the findings and draw conclusions. Of all the factors analyzed, only perceived organizational support and autonomy were found to influence commitment in this sample. The relevance of these findings for business and academia is discussed.

A Comparison of Measures of Signal-To-Noise Ratio, Jitter, Shimmer, and Speaking Fundamental Frequency in Smoking and Nonsmoking Females (open access)

A Comparison of Measures of Signal-To-Noise Ratio, Jitter, Shimmer, and Speaking Fundamental Frequency in Smoking and Nonsmoking Females

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.

Heresy vs. Orthodoxy: The Preus/Tietjen Controversy (open access)

Heresy vs. Orthodoxy: The Preus/Tietjen Controversy

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 Effects of Long Term Moderate Ethanol Intake on the Immune Response in Rats (open access)

The Effects of Long Term Moderate Ethanol Intake on the Immune Response in Rats

Using a rat model, the effects of a single dose or six to twelve months of daily oral administration of ethanol on the immune system were determined. The rats were challenged with sheep red blood cells after the various dosing periods to elicit an immune response. Immune system responsiveness was determined by means of white blood cell counts and differentials, antibody titers, and T-cell numbers. No deleterious effects of the ethanol on the immune response were seen, while the female alcohol-fed rats showed a significant increase in T-Cell numbers, white blood cell counts, and lymphocytes over the sham group.

Studies on Poly (ADP-ribose) Synthesis in Lymphocytes of Systemic Lupus Erythematosus Patients (open access)

Studies on Poly (ADP-ribose) Synthesis in Lymphocytes of Systemic Lupus Erythematosus Patients

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.

Molecular Cloning and Functional Analysis of Transposable Mercury Resistance Genes Encoded by the OCT Plasmid (open access)

Molecular Cloning and Functional Analysis of Transposable Mercury Resistance Genes Encoded by the OCT Plasmid

Translocation of a 17.1 kilobase region of the OCT plasmid encoding mercury resistance (mer) in Pseudomonas putida was shown to occur in a recombination-deficient host with plasmid PP1 serving as a recipient replicon. The frequency of transposition in Pseudomonas was estimated at 10^3 -10 -^2, but undetectable in Escherichia soli. ' DNA comprising all of mr as well as subregions there of were cloned and subjected to DNA sequence analysis. Like other transposons, mer was found to contain inverted repeat sequences at its termini. These were similar to, but not identical to the inverted repeat structures found in the prototypical mercury resistance transposon Tn501 from E. aeruginosa.

Whitman's Failures: "Children of Adam" in the Light of Feminist Ideals (open access)

Whitman's Failures: "Children of Adam" in the Light of Feminist Ideals

Walt Whitman was a feminist, and this assertion can be supported by excerpts from his prose, poetry, and conversation. Furthermore, the poet's circle of associates, chronology, and place of residence also lend credence to the hypothesis stating Whitman's subscription to feminist credos. A pro-feminine attitude is evident in much of Whitman's work, and his ties to the women's rights movement of the nineteenth century do influence the poet's portrayal of women. But the section of poems titled "Children of Adam" proves to be an anomaly in Walt Whitman's feminist attitudes. Instead of portraying women as equals, able to walk a path of equanimity with males, the women of "Children of Adam" are often obscured in linguistic veils or subjugated to the poet's Adamic rhetoric.

Job Rating and Satisfaction of Radio Station General Managers in the Institutional Climate of Deregulation (open access)

Job Rating and Satisfaction of Radio Station General Managers in the Institutional Climate of Deregulation

This study tested the job satisfaction of major market radio station general managers in the aftermath of deregulation. The study consisted of two phases, a quantitative, anonymous, mail survey utilizing the nationally recognized Job Descriptive Index (JDI); and a qualitative follow-up telephone interview. Of 246 general managers solicited, 144 returned usable JDI surveys. The JDI consisted of six separate scales, each measuring satisfaction on a different aspect of the job. The followup telephone interview comprised seven questions designed specifically to explore the effects of broadcast deregulation on the respondents. Two hypotheses were tested. The hypotheses tested for differences in job satisfaction scores between radio station general managers and the normative scores of individuals of similar education and job tenure in other industries. In most of the subscales tested there was no significant difference between the two groups. The qualitative telephone survey found widespread dissatisfaction with the effects of deregulation on the broadcast medium.

"Eyre," a Three Movement Instrumental Work for Small Chamber Ensemble (open access)

"Eyre," a Three Movement Instrumental Work for Small Chamber Ensemble

"Eyre" is a composition of approximately sixteen minutes duration for an instrumental ensemble consisting of two flutes, oboe, B𝄭 clarinet, bassoon, guitar, and cello. It is inspired by a large seasonal lake basin in South Australia of the same name. The piece is divided into three movements; the first is fast and quasi sonata-allegro form without the recapitulation; the second is slow and through-composed; and the third, essentially the missing recapitulation from the first movement. Much of the motivic material for the piece is derived from the initial progression of triads. Harmonic and melodic development of this material contains some modal tendencies. While the overall effect tends toward equal weighting of the instrumental forces, there is some featuring of the guitar and an interplay between the woodwind and string instruments.

Circulatory and Respiratory Responses to Cycle Ergometry at Different Pedal Rates (open access)

Circulatory and Respiratory Responses to Cycle Ergometry at Different Pedal Rates

The effects of moderate workload exercise at different pedal rates on circulatory and respiratory parameters were studied. Five subjects performed seven discontinuous constant-load cycle ergometer tests of 30 minutes duration at pedal rates of 40, 50, 60, 70, 80, 90 and 100 rpm. Oxygen uptake and carbon dioxide production were determined by standard open circuit spirometry, while heart rate was recorded by electrocardiograph. The CO₂ rebreathing procedure was administered during the exercise bout in order to determine cardiac output. Blood pressure was determined for each test, and total peripheral resistance was calculated. The findings indicate that progressive increases in pedal frequency during discontinuous constant-load cycle ergometry produce progressive increases in cardiovascular, respiratory and metabolic responses and a decrease in gross exercise mechanical efficiency. The results indicate that oxygen uptake, cardiac output, heart rate, ventilation and arterial-venous oxygen difference increases curvilinearly as pedal rate increases, possibly as a result of increases in recruitment of muscle fibers and/or muscle groups. These findings suggest that circulatory and respiratory responses are due to "central command" which sets the basic efferent response pattern. However, this effector pattern is modulated by afferent input originating from the legs during progressive increases in pedal rate.

Comparative Toxicity of Refuse-Derived Fuel Fly Ash on Two Species of Earthworms, Lumbricus terrestris and E. foetida, Using an Artificial Soil Exposure Protocol

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%.

Premorbid Level of Functioning and Perspective Taking During Self-Narratives

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.

Diplomacy Rhetoric and the Human Rights Appeals of Jeane J. Kirkpatrick and Vernon A. Walters (open access)

Diplomacy Rhetoric and the Human Rights Appeals of Jeane J. Kirkpatrick and Vernon A. Walters

This thesis investigates the extent to which Ambassador Kirkpatrick's and Ambassador Walters' United Nations discourses on human rights reflects the rhetorical themes of "prophetic dualism" and "technocratic realism." A metaphoric analysis of six speeches reveals that both Kirkpatrick's and Walters' arguments were framed through an ideological division between Democracy and Communism. The presence of "prophetic dualism" in Kirkpatrick's and Walters' discourses is explained as an extension of President Reagan's bipolar rhetoric on world affairs. The presence of "technocratic realism" in Walters' discourse is described as resulting from a unique set of political and rhetorical factors. The exacting nature of "prophetic dualism" may make it ill suited as a method of argument in the realm of diplomacy.
