Training Condom Use Skills for Sexually Active College Students

Description: 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.

Electron Density and Collision Frequency Studies Using a Resonant Microwave Cavity as a Probe

Description: Electron densities and collision frequencies were obtained on a number of gases in a dc discharge at low pressures (0.70-2mm of Hg). These measurements were performed by microwave probing of a filament of the dc discharge placed coaxially in a resonant cavity operating in a TM₀₁₀ mode. The equipment and techniques for making the microwave measurements employing the resonant cavity are described. One of the main features of this investigation is the technique of differentiating the resonance signal of the loaded cavity in order to make accurate measurements of the resonant frequency and half-power point frequencies.

The Effect of Giving Class Time for Reading on the Reading Achievement of Fourth Graders and the Effect of Using a Computer-Based Reading Management Program on the Reading Achievement of Fifth Graders

Description: This study investigated the problem that educators have throughout the state of Texas. The problem educators have is that reading scores continue to fall short of state expectations. This study investigated the effectiveness of 90 minutes of class time given for reading to students who use the Electronic Bookshelf Program and the effectiveness of the Electronic Bookshelf Program, which is being sold to school districts throughout the nation. The literature review focused on the effectiveness of independent reading on reading achievement, and the effectiveness of using computer-based reading programs to increase reading achievement.

Effects of Music on Vividness of Movement Imagery

Description: The purpose of the investigation was to determine the effects of music on self reported vividness of movement imagery. Eighty-four undergraduate kinesiology majors (42 males; 42 females) were subjects. Based on identical perceptions of precategorized music (classical and jazz), selected subjects were randomly assigned to one of three music treatment conditions (sedative, stimulative, and control) and administered the Vividness of Movement Imagery Questionnaire. A 3 x 2 x 2 (Treatment x Gender x Perspective) ANOVA with repeated measures on the last factor was employed. The results revealed that the two music conditions significantly enhanced the vividness of internal and external imagery perspectives when compared to the no music condition, and that music facilitated the vividness of males and females equally.

Chemical Equilibria in Binary Solvents

Description: Dissertation research involves development of Mobile Order Theory thermodynamic models to mathematically describe and predict the solubility, spectral properties, protonation equilibrium constants and two-phase partitioning behavior of solutes dissolved in binary solvent mixtures of analytical importance. Information gained provide a better understanding of solute-solvent and solvent-solvent interactions at the molecular level, which will facilitate the development of better chemical separation methods based upon both gas-liquid and high-performance liquid chromatography, and better analysis methods based upon complexiometric and spectroscopic methods. Dissertation research emphasizes chemical equilibria in systems containing alcohol cosolvents with the understanding that knowledge gained will be transferable to more environmentally friendly aqueous-organic solvent mixtures.

Susceptibility of College Students to Alcohol Abuse and Alcohol Related Problems: the Impact of Family Environmental Factors

Description: The purpose of this study was to examine the impact of parental divorce, level of family conflict, and family history of alcoholism on the alcohol use patterns of college students. Gender differences were also explored. Multivariate Analysis of Variance revealed mixed results. Parental marital status was found to have no significant effect on college students' alcohol behavior. High family conflict had a significant impact on both level of current alcohol use and level of alcohol related problems. A positive family history of alcoholism was found to have effects on the level of alcohol related problems encountered by students. Gender played a significant role, with males reporting higher levels of alcohol-related problems. No significant interactions were found. Results, contributions and limitations of the study are discussed.

Creating a Mythistory: Texas Historians in the Nineteenth Century

Description: Many historians have acknowledged the temptation to portray people as they see themselves and wish to be seen, blending history and ideology. The result is "mythistory." Twentieth century Texas writers and historians, remarking upon the exceptional durability of the Texas mythistory that emerged from the nineteenth century, have questioned its resistance to revision throughout the twentieth century. By placing the writing of Texas history within the context of American and European intellectual climates and history writing generally, from the close of the eighteenth century to the beginning of the twentieth, it is possible to identify a pattern that provides some insight into the popularity and persistence of Texas mythistory.

Nicotinic Acetylcholine Receptor α3 mRNA in Rat Visual System After Monocular Deprivation

Description: In situ hybridization was used to examine effects of monocular enucleation on nicotinic acetylcholine receptor subunit cc3 mRNA in the rat dLGNand visual cortex. After 28 days postoperative, there were no significant differences in α3 mRNA density between the contralateral (deprived) and ipsilateral (non-deprived) sides. The lack of obvious effects of visual deprivation on α3 mRNA density suggests that other factors, possibly intrinsic to dLGNand visual cortex, govern the postnatal expression of α3 mRNA.

Increasing Differentiation on Vocational Assessments among Gifted High School Students

Description: Multipotentiality makes career counseling with gifted students difficult. High-flat vocational profiles give the impression that gifted students can develop a wide range of abilities to an equally high level. High-flat vocational profiles may be due to assessments that consider abilities and disregard interests and values, and ceiling effects from the use of age-appropriate, rather than cognitively-appropriate measures. Subjects included 170 gifted students from a residential, early college entrance program (M=15.9 yrs., SD=.361). Subjects completed the Scholastic Aptitude Test, Self-Directed Search, and Study of Values. McNemar's Test of Correlated Proportions shows the proportion of multipotential profiles decreases significantly when cognitively-appropriate measures of interests and values are considered, in addition to abilities. Pearson Chi-square shows no ethnic differences.

Participation in Student Financial Aid Programs during the Freshman Year and Persistence in a Private University

Description: The study determined the overall persistence rate of first-time full-time entrants into a mid-sized private university during the fall semesters 1989 to 1991 to the 2nd year (1990 to 1992). The study compared the retention rate of recipients and nonrecipients of a variety of financial aid programs. Included is a comparison of groups receiving various types of financial assistance and whether or not there are differences between the groups with respect to types of assistance, gender, ethnicity (African American, Hispanic, Anglo), high school grade point average, and national test scores (SAT, ACT). The types of assistance studied were categorized by academic scholarships, university-operated student employment, need-based grants, activity awards, entitlements, and loans. The question of whether renewal, elimination, or reduction in assistance relates to retention was also studied.

Unique applications of cultured neuronal networks in pharmacology, toxicology, and basic neuroscience

Description: This dissertation research explored the capabilities of neuronal networks grown on substrate integrated microelectrode arrays in vitro with emphasis on utilizing such preparations in three specific application domains: pharmacology and drug development, biosensors and neurotoxicology, and the study of burst and synaptic mechanisms. Chapter 1 details the testing of seven novel AChE inhibitors, demonstrating that neuronal networks rapidly detect small molecular differences in closely related compounds, and reveal information about their probable physiological effects that are not attainable through biochemical characterization alone. Chapter 2 shows how neuronal networks may be used to classify and characterize an unknown compound. The compound, trimethylol propane phosphate (TMPP) elicited changes in network activity that resembled those induced by bicuculline, a known epileptogenic. Further work determined that TMPP produces its effects on network activity through a competitive inhibition of the GABAA receptor. This demonstrates that neuronal networks can provide rapid, reliable warning of the presence of toxic substances, and from the manner in which the spontaneous activity changes provide information on the class of compound present and its potential physiological effects. Additional simple pharmacological tests can provide valuable information on primary mechanisms involved in the altered neuronal network responses. Chapter 3 explores the effects produced by a radical simplification of synaptic driving forces. With all synaptic interactions pharmacologically limited to those mediated through the NMDA synapse, spinal cord networks exhibited an extremely regular burst oscillation characterized by a period of 2.9 ± 0.3 s, with mean coefficients of variation of 3.7, 4.7, and 4.9 % for burst rate, burst duration, and inter-burst interval, respectively (16 separate cultures). The reliability of expression of this oscillation suggests that it may represent a fundamental mechanism of importance during periods of NMDA receptor dominated activity, such as embryonic and early postnatal development. NMDA synapse mediated activity produces a precise ...

Applications of Reductive Analytical Techniques in the Phrygian Settings of the Orgelbüchlein by J.S. Bach

Description: 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.

Language Policy, Protest and Rebellion

Description: The hypothesis that language discrimination contributes to protest and/or rebellion is tested. Constitutional language policy regarding administrative/judicial, educational and other matters is measured on three separate scales developed for this study; the status of each minority group's language under its country's policy is measured by another set of scales. Protest and rebellion variables are taken from Gurr's Minorities at Risk study. Findings include an indication that group language status contributes positively to protest and rebellion until a language attains moderate recognition by the government, at which point status develops a negative relationship with protest and rebellion, and an indication that countries with wider internal variations in their treatment of language groups experience higher levels of protest and rebellion on the part of minority groups.

Light Spectra Distributions in Temperate Conifer-Forest Canopy Gaps, Oregon and in Tropical Cloud-Forest Canopy, Venezuela

Description: Light spectra distributions were measured in two different montane forests: temperate and tropical. Spectral light measurements were made in different sized canopy gaps in the conifer forest at H. J. Andrews Experimental Forest in Oregon, USA. Researchers at Oregon State University created these gaps of 20 m, 30 m, and 50 m in diameter. In the tropical cloud forest, spectral light measurements were made in two plots that were permanently established at La Mucuy Parque Nacional in Venezuela, in collaboration with researchers at Universidad de Los Andes. In both studies, spectra and distributions of physiologically active light were analyzed: red, far-red, R/FR ratio, and blue light.

An Exploratory Investigation of the Origins and Regulatory Actions of the United Kingdom's Financial Reporting Review Panel

Description: In 1990, the accounting profession and the British government worked together to establish a new regulatory framework for financial reporting in the United Kingdom (UK), the Financial Reporting Council (FRC) and its two subsidiaries, the Accounting Standards Board (ASB) and the Financial Reporting Review Panel (FRRP). The FRRP enforces companies' compliance with the ASB's accounting standards and the accounting provisions of the UK Companies Act. Only one study, Brandt et al. (1997), has examined the activities and effectiveness of the FRRP. This dissertation attempts to extend Brandt et. al (1997) and add to understanding of the origins and regulatory actions of the FRRP.

The Role of a Point Loss Contingency on the Emergence of Derived Relations in the Absence of Original Relations

Description: 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.
