Finitness and Verb-Raising in Second Language Acquisition of French by Native Speakers of Moroccan Arabic
In this thesis, the three hypotheses on the nature of early L2 acquisition (the Full Transfer/Full Access view of Schwartz and Sprouse (e.g., 1996), the Minimal Trees view of Vainikka and Young-Scholten (e.g., 1996), and the Valueless Features view of Eubank (e.g., 1996)), are discussed. Analysis of the early French production by two native speakers of Moroccan Arabic is done to determine if the L1 grammar is transferred onto the L2 grammar. In particular, the phenomena of verb-raising (as determined by the verb's position vis-a-vis negation) and finiteness are examined. The results of this study indicate that the relevant structures of Moroccan Arabic do not transfer onto the emerging French grammar.

Cure Kinetics and Processing Parameters of Neat and Reinforced High Performance Epoxy Resins: Evaluation of Techniques
Access:
Use of this item is restricted to the UNT Community
Kinetic equation parameters for the curing reaction of a commercial glass fiber reinforced high performance epoxy prepreg composed of the tetrafunctional epoxy tetraglycidyl 4,4-diaminodiphenyl methane (TGDDM), the tetrafunctional amine curing agent 4,4Â’-diaminodiphenylsulfone (DDS) and an ionic initiator/accelerator, are determined by various thermal analysis techniques and the results compared. The reaction is monitored by heat generated determined by differential scanning calorimetry (DSC). The changes in physical properties indicating increasing conversion are followed by shifts in glass transition temperature determined by DSC and temperature-modulated DSC (TMDSC), thermomechanical (TMA) and dynamic mechanical (DMA) analysis and thermally stimulated depolarization (TSD). Changes in viscosity, also indicative of degree of conversion, are monitored by DMA. Thermal stability as a function of degree of cure is monitored by thermogravimetric analysis (TGA). The parameters of the general kinetic equations, including activation energy and rate constant, are explained and used to compare results of various techniques. The utilities of the kinetic descriptions are demonstrated in the construction of a useful time-temperature-transformation (TTT) diagram for rapid determination of processing parameters in the processing of prepregs.

Hospitality Students' Attitudes and Behavioral Intentions toward Learning and Using Computer Technology
Access:
Use of this item is restricted to the UNT Community
Following Ajzen/Fishbein's 1980 Theory of Reasoned Action, influences of hospitality students' external variables (age, gender, university classification, and work experience) on computer attitudes, and relationships between computer attitudes and intentions to learn and use computers were tested. A sample of 412 hospitality students completed two measurements: Loyd/Gressard's 1984 Computer Attitude Scale, and Behavioral Intentions to Learn and Use Computers. Males and females had positive computer attitudes. Graduates had more positive computer attitudes. No interaction effect existed between gender and classification. No relationships existed between age and work experience on computer attitudes. Computer attitudes positively correlated with intentions to learn and use computers. Results supported the Theory of Reasoned Action. External variables partially influence attitudes and attitudes influence intentions.

Development of a Coaxiality Indicator
Access:
Use of this item is restricted to the UNT Community
The geometric dimensioning and tolerancing concept of coaxiality is often required by design engineers for balance of rotating parts and precision mating parts. In current practice, it is difficult for manufacturers to measure coaxiality quickly and inexpensively. This study examines feasibility of a manually-operated, mechanical device combined with formulae to indicate coaxiality of a test specimen. The author designs, fabricates, and tests the system for measuring coaxiality of holes machined in a steel test piece. Gage Repeatability and Reproducibility (gage R&R) and univariate analysis of variance is performed in accordance with Measurement System Analysis published by AIAG. Results indicate significant design flaws exist in the current configuration of the device; observed values vary greatly with operator technique. Suggestions for device improvements conclude the research.

Techniques of Sensual Perception: The Creation of Emotional Pathways
Access:
Use of this item is restricted to the UNT Community
Some artists strive to create artwork that has aesthetic value. If a piece of artwork has the ability to capture the attention of an audience, it must contain strong sensual attributes. Thus, understanding how to design an art form to contain strong sensual attributes may increase the possibility of an aesthetic experience. Since aesthetics is an experience of sensations perceived when in contact with a creative form in any artistic discipline, it is necessary for an artist to understand the nature of the sensual experience. In understanding the sensual experience, artists may be able to create techniques to enhance the aesthetic experience of their work. My video piece, entitled Ararat is a study of methods to enhance the sensual experience. I hope to accomplish this by means of using techniques that optimize an audience's perceptual experience.

Underwater Optical Properties of Lake Texoma (Oklahoma-Texas) Using Secchi Disk, Submarine Photometer, and High-Resolution Spectroscopy
The underwater optical climate of Lake Texoma was measured at eleven fixed stations from August 1996 to August 1997. Secchi transparency and submarine photometry characterized seasonal and spatial values of secchi depth (SD), vertical attenuation coefficient (η''), and depth of euphotic zone (Zeu). Indices of Zeu:SD and η'' × SD were compared with universally applied values derived from inland and coastal waters. Turbidity explained 76% of the variation (p = 0.0001) of η'' among water quality parameters, including chlorophyll-α. Using a spectroradiometer, spectral signatures of chlorophyll-α and turbidity were located. Stations with low turbidity exhibited a distinct green reflectance peak around 590-610 nanometers, indicating presence of chlorophyll-α. Stations with high turbidity exhibited a reflectance peak shift towards the red spectrum, making it difficult to detect the chlorophyll signature. Derivative analysis of the reflectance signal at 590-610, and 720-780 nanometers allowed discrimination of this chlorophyll signature from those of turbidity (0.66 ≤ r^2 ≤ 0.99).

Personality Correlates of Anorexia Nervosa in a Nonclinical Sample
The purpose of this study was to examine the relationship between anorexia nervosa and several personality traits. Past research in this area has been contradictory for several reasons. Sociocultural theories have described the media's role in promoting eating disorders by portraying a thin body-type as the ideal. However, they have neglected to describe the personality ideal which our society promotes in women. It is proposed here that anorexics incorporate and oppose this ideal. Therefore, the anorexic personality is one filled with conflict.

Cloning of Carbonic Anhydrase from Cotton (Gossypium hirsutum L.)
Carbonic anhydrase is a ubiquitous zinc-metalloenzyme that catalyzes the interconversion of carbon dioxide and carbonate and has been found to play a wide range of roles in animals, plants and bacteria. Cotton genomic and cDNA libraries were screened for the plastidial isoform of carbonic anhydrase. The nucleotide sequences of two 1.2 Kb partial cDNA clones were determined. These clones exhibit high homology to carbonic anhydrases from other dicot plants and possess all the expected peptide motifs. For example, serine and threonine rich chloroplastic targeting peptide and conserved zinc binding residues are both present. These clones were utilized to isolate two carbonic anhydrase genes that were shown to encode different isoforms by PCR and RFLP analysis.

Applications of Reductive Analytical Techniques in the Phrygian Settings of the OrgelbĂĽchlein by J.S. Bach
This study aims to two problematic aspects of the Phrygian mode: a. the development of a harmonic pattern at the cadence that differs from that of the other modes and of the major and minor modes as well; b. the observation that the Phrygian scale inverts all of the intervallic properties of the Major scale. The result of these two observations is that when the reductive techniques of Heinrich Schenker are applied in the Phrygian repertory, melodic and harmonic properties are brought into conflict with each other. However, application of alternative models of the Ursatz developed by Lori Burns has certain benefits for demonstrating musical properties in the Phrygian repertory.

Effects of External Electric Fields on Light Transmittance in Isolated Crayfish Nerves
Acute effects of a pulsed external electric field (PEEF) at 20 V/cm and a d.c. EEF at 90 V/cm on light transmittance in an isolated compound crayfish nerve was measured. In a third series, the nerve was pre-treated with the Na+ channel blocker tetrodotoxin (TTX). A PEEF produced an irreversible increase in the variation of light transmittance in normal nerves but a reversible increase in TTX treated nerves. This data was statistically insignificant. The d.c. EEFs produced a reversible and statistically significant enhancement of variation in light transmittance in both untreated and TTX-treated nerves. The findings may be due to either (1) an alteration in the ion/fluid flux within the nerve or (2) a physical alteration of protein molecules in the membranes.

Training Condom Use Skills for Sexually Active College Students
Eighty-nine single, sexually active, heterosexual college students (ages 17-24) participated in one of two intervention conditions. Experimental groups were taught skills specific to condom use and sexual communication via a multimedia presentation. Control groups viewed a video on an unrelated topic. Individuals in the experimental conditions were expected to show higher levels of self-efficacy, greater knowledge concerning diseases, and improved attitudes about condoms immediately following the intervention. They were also expected to report safer sexual practices at the one month follow-up. Findings reveal that improved attitude and knowledge scores did not translate into behavioral changes.

Song of Pi-Pa
Sona of Pi-Pa is a composition set to a poem to be performed by soprano and mixed instrumental ensemble. The formal plan is through-composed and the organization of each individual piece is largely determined by the structure of the poetic text. The text, drawn from Song of Pi-Pa by Po Chu-i, depicts the story of how the poet became overwhelmed by the chance hearing of a virtuosic performance of a woman playing the pi-pa. The general characteristics of the work reflect the assimilation of certain non-western musical and philosophical influences. Traditional western compositional techniques are also employed in the treatment of thematic materials, musical form, instrumentation, and the developmental process. The total performance time for this composition is approximately twenty-six minutes.

An Assessment of College Students' Attitudes and Empathy toward Rape
The purpose of this study was to assess rape attitudes and empathy levels of students at a university in North Texas. The Attitudes Toward Rape questionnaire and the Rape Empathy Scale were administered to 387 undergraduate students. Dependent variables were attitudes and empathy and independent variables were prior knowledge or experience as a rape victim, having female siblings, gender, marital status, and age. Significance was found between rape-intolerant attitudes and both prior experience as a victim (p < .001), and gender (p < .001). Significance was also found between empathy and experience as a rape victim (p < .035) and gender (p < .032).

The Role of a Point Loss Contingency on the Emergence of Derived Relations in the Absence of Original Relations
The role of point loss for symmetrical relations introduced simultaneously with probe trials in the absence of original relations on all probe trial performances was evaluated. Training was completed after six conditional discriminations were established in two contexts. Point loss was introduced simultaneously with probe trials in the absence of original relations in the first context. Probe trials with no point loss in the absence of original relations were introduced in the second context. The simultaneous introduction of probe trials and the point loss contingency may in some cases prevent the emergence of an equivalence class in the context that contained the point loss as well as in the context where no point loss occurred.

Racial Differences in Female Achievement Motivation and Motivation to Work
In the present project racial differences in female achievement motivation and motivation to work were examined, and related this information to the theory that African American females, when compared to White females, are less likely to marry someone equal to themselves in the areas of education, employment, and earning potential because of an assumed shortage of suitable African-American males. It was hypothesized that African-American females would score higher on assessments of achievement motivation and motivation to work, and rate lower the likelihood of meeting and marrying a partner equal in education level, employment level, and earning potential than would White females. Data analysis supported all hypotheses. The results were discussed in the context of the female achievement motivation literature as well as the literature concerning female motivation to work.
