The purpose of this study is to examine historically the presidential administration of John Christopher Stevens at Abilene Christian University from 1969 to 1981. During this time the institution grew in enrollment, faculty, facilities, endowment, and quality of educational opportunity. Limited to selected experiences and accomplishments, this dissertation examines Stevens' personal and administrative characteristics through interviews with him and those who worked with him. Materials were also used from Stevens' Presidential Archives in the Callie Faye Milliken Special Collections of the Herman and Margaret Brown Library at Abilene Christian University.

The University of Texas of the Permian Basin (UTPB) is a public university that serves over 4,500 undergraduate and graduate students as a branch of the University of Texas system located in Odessa, Ector County, Texas. The UTPB was established as an upper-division and graduate school on February 4, 1969, and first opened its doors to students in September, 1973. This historical study focuses on the development and progress of the UTPB from its inception until it was elevated from an upper-level institution to a four-year university twenty-two years later. The formation, mission, and curriculum are examined as well as are faculty and student characteristics and support. This study addresses the background history of higher education in the region, the role of community and college leaders in the UTPB's creation and struggle for four-year status, and the UTPB's unique features. The study was conducted by collecting data from available primary and secondary sources. The written data were then subjected to both external and internal criticism to determine the authorship and meaning of the documents. To explain events and put the written documents in context, oral histories, given by participants, were used. The educational opportunities offered by the UTPB have enriched …

The Mexican Revolution probably affected Texas more than any other state. As the Revolution intensified, Texans responded with increased efforts to shape the Mexican policies of the Woodrow Wilson administration. Some became directly involved in the Revolution and the U.S. reaction to it, but most Texans sought to influence American policy toward Mexico through pressure on their political leaders in Austin and Washington. Based primarily on research in the private and public papers of leading state and national political figures, archival sources such as the Congressional Record and the Department of State's decimal file, major newspapers of the era, and respected works, this study details the successes and failures that Texans experienced in their endeavors to influence Wilson's Mexican policies.

Depression is an independent risk factor for morbidity and mortality in patients with coronary artery disease (CAD). Altered autonomic nervous system (ANS) activity, a common feature of depression, is also a risk factor for cardiac events in patients with CAD. Heart rate variability (HRV) reflects ANS activity, and reduced HRV predicts morbidity in cardiac populations. The purpose of this study was to determine whether differences in HRV exist between depressed and nondepressed patients with CAD. Twenty-one depressed inpatients, with angiographically documented CAD were retrospectively matched to 21 nondepressed CAD patients by sex, age, and smoking status. Demographic, medical, psychological interview data, and 24-hour ECG recordings were obtained. Depressed subjects had significantly lower HRV, or trends toward lower HRV, than nondepressed subjects, even after controlling for severity of CAD. Subject groups did not differ on left ventricular ejection fraction, history of myocardial infarction, or any other relevant medical variable assessed. These results suggest that depression is associated with decreased HRV in patients with CAD, and may help to explain the increased rates of cardiac events observed in CAD patients with depression.

The Schedule for Affective Disorders and Schizophrenia-Change Version (SADS-C), the Social Adjustment Scale-Patient Version II (SAS-PATII) and the Command Hallucination Questionnaire (CAQ) were administered to 86 psychotic inpatients to investigate the relationship between command hallucinations, aggressive behavior, and compliance. Two SADS-C items ("severity of hallucinations" and "depersonalization") were useful as indicators of command hallucinations. Ninety-two percent had complied with their command at least once in the past month. Three SADS-C variables related to compliance with command hallucinations were identified: middle insomnia, the belief that the voice was acting in your best interest, and overt irritability. The patients' level of distortion of reality did not appear to influence compliance rates. Results also indicated that patients who experience command hallucinations were not significantly more or less dangerous than other psychotic inpatients.

To date, no research exists examining criterion-related validity of alternate, computerized forms of the Category Test. The intent of this study was to address criterion-related validity of three full forms of the Category Test. In that, the goal was to examine equivalency of each version in their ability to differentiate brain-injured from non-brain-injured individuals. Forty-nine (N = 49) healthy adults and 45 (N = 45) brain-injured adults were tested using three versions of the Category Test, the BDI, and the WAIS-R NI. ANOVA indicated no significant differences between versions of the Category Test or an interaction between Category Test version and group membership on the total error score. MANOVA performed between versions of the Category Test and Subtest error scores indicated significant differences between versions on Subtest 3 and Subtest 6. Group membership (brain-injured v. non-brain-injured) produced a significant main effect on all subtests of the Category Test except Subtest 2. Several exploratory analyses were performed examining the relationship between neuropsychological impairment, group membership based on Category Test error scores, and the WAIS-R NI. Clinical applications, such as the use of serial testing to index neurorehabilitation gains, were discussed.

Salvage of pyrimidine nucleosides and bases by S. griseus and the regulation of aspartate transcarbamoylase (ATCase) were studied. The velocity-substrate curve for S. griseus ATCase was hyperbolic for both aspartate and carbamoylphosphate. The enzyme activity was diminished in the presence of ATP, CTP, or UTP. The synthesis of ATCase was repressed in cells grown in the presence of exogenous uracil. The specific activity of cells grown with uracil was 43 percent of that for cells grown in minimal medium only. Maximal ATCase and dihydroorotase activities were found in the same column fraction after size-exclusion chromatography, suggesting that both activities could reside in the same polypeptide. The pyrimidine salvage enzymes cytosine deaminase and uridine phosphorylase were identified in S. griseus using HPLC reversed-phase chromatography.

Using the Defense Mechanism Manual (Cramer, 1991), Thematic Apperception Test (TAT) stories of 29 sexually abused female subjects and 28 non-abused female clinical control subjects were rated for the frequency of use of denial, projection, and identification.

The Comanche Indians presented a major challenge to the Republic of Texas throughout its nine-year history. The presence of the Comanches greatly slowed the westward advancement of the Texas frontier, just as it had hindered the advancing frontiers of the Spaniards and Mexicans who colonized Texas before the creation of the Republic. The Indian policy of the Republic of Texas was inconsistent. Changes in leadership brought drastic alterations in the policy pursued toward the Comanche nation. The author examines the Indian policy of the Republic, how the Comanches responded to that policy, and the impact of Texan-Comanche relations on both parties.

Social support needs have neither been formally addressed nor assessed in prior research with parents of children of special needs. Typically, behavioral management skills, specific knowledge about the disorder/illness/handicap, parents' self-perception, and participants' evaluation of program effectiveness have been measured. Research information collected to date supports the exploration of social support as a treatment intervention. Therefore, the purpose of the present study was to examine perceived social support for parents of children with ADHD who completed a parent training program. The program, entitled "ADHD Parent Training," included information about ADHD, behavior management strategies, child advocacy, and a social support component. Upon completing the ADHD Parent Training program, parents were expected to perceive a significantly greater amount of social support than they did prior to treatment. In addition, the relationship between change in perceived social support and the more traditionally assessed outcomes of parent training was examined (parent's satisfaction with treatment, parent's perception of child's progress, and teacher's perception of child's progress).

It has been hypothesized that a disproportionate percentage of the blind population are learning disabled. In the past, norms and technology were not available to assess in a cost effective manner the blind client's neuropsychological functioning. Norms for the Wide Range Achievement Test - Revised (WRAT-R2) are now available for a blind population without any neuropsychological dysfunctioning. This study utilized the adapted WRAT-R2 and the Comprehensive Vocational Evaluation System (CVES), a neuropsychological test battery adapted for the blind, to investigate the possibility that learning disabilities are present in the adult blind population. Suspected learning disabled, blind subjects were compared with normal blind subjects. There were significant neuropsychological differences between the two groups.

Using a sociolinguistic and post-colonial approach, I analyze Irish dramas that speak about language and its connection to national identity. In order to provide a systematic and wide-ranging study, I have selected plays written at approximately fifty-year intervals and performed before Irish audiences contemporary to their writing. The writers selected represent various aspects of Irish society--religiously, economically, and geographically--and arguably may be considered the outstanding theatrical Irish voices of their respective generations. Examining works by Alicia LeFanu, Dion Boucicault, W.B. Yeats, and Brian Friel, I argue that the way each of these playwrights deals with language and identity demonstrates successful resistance to the destruction of Irish identity by the dominant language power. The work of J. A. Laponce and Ronald Wardhaugh informs my language dominance theory. Briefly, when one language pushes aside another language, the cultural identity begins to shift. The literature of a nation provides evidence of the shifting perception. Drama, because of its performance qualities, provides the most complex and complete literary evidence. The effect of the performed text upon the audience validates a cultural reception beyond what would be possible with isolated readers. Following a theoretical introduction, I analyze the plays in chronological order. Alicia LeFanu's The …

The use of scales on the Personality Assessment Inventory (PAI) to detect defensiveness in criminal and nonclinical samples was evaluated. Forty-five male inmates of a county jail and 38 male undergraduate psychology students were provided with incentives to complete the PAI under two conditions: standard instructions and experimental instructions to feign a specific, positive role. The sequence of instructions was counterbalanced in both samples for the purpose of examining ordering effects. A repeated measures multivariate analysis of variance (MANOVA) was performed, yielding significant main effects of condition, group and order. Additionally, a step-wise discriminant function analysis significantly predicted group membership (i.e., subjects under honest and faking conditions) with a hit rate = 84.4%. Finally, a more effective cutting score for the Positive Impression scale was recommended.

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.

This dissertation breaks new ground. It examines the perceptions of older adults towards AIDS prevention. Using the National Health Interview Survey, 1988: AIDS Knowledge and Attitudes Supplement, a modified Health Belief Model is developed. Despite the low number of older adults 55+ with AIDS, some extenuating circumstances increase their risk of AIDS contraction. Older adults have lower levels of knowledge about AIDS, weaker immune systems and receive more blood transfusions. Societal influences include educational neglect at the hands of physicians, healthcare workers and social service personnel. The first stage of the dissertation involved establishing older adults as an at-risk population through an extensive literature review. Next, the data was described utilizing frequencies, correlations and factor analysis. Frequencies clearly indicated that older adults in the data set had low levels of AIDS knowledge and did not view themselves at risk for AIDS contraction. Correlations between the variables were minimal. A modified Health Belief Model was developed and tested. Multiple regression determined that minimal variation in the two dependent variables, "Perceived Effectiveness of Effective Methods to Prevent AIDS Contraction" and "Perceived Effectiveness of Ineffective Methods to Prevent AIDS Contraction" was accounted for by the independent variables. Although F ratios allowed rejection of …

This study investigated the influence of age and health status on verbal and visual memory and attention. The objective was to select subjects resembling participants in normative studies, and to contrast the genuinely healthy component with the "contaminants." A rigorous and detailed self-report of health status plus a standard neurological examination were used to screen and divide subjects into two health status groups: normal and super healthy. It was speculated that the strong effect of age on memory and attention commonly found among the elderly would be diminished with more restrictive control over health status.

It has been suggested that the use of standardized intelligence tests is biased against minorities. This study investigates the newly revised Wechsler Intelligence Scale for Children-III in which Wechsler states that the new scale has eliminated biased items. Comparisons of the scores on the WISC-R and the WISC-III of a clinical population of sixteen African American and eighteen Caucasian males, ages ten to sixteen, revealed significant differences between the two groups on the WISC-III. The minority scores decreased predictably from the WISC-R to the WISC-III, but the Caucasian scores increased rather than decreasing. The findings of this study do not support the predictions and goals of revision as stated in the manual of the WISC-III.

The Bill J. Priest Institute for Economic Development is an entity created in the Dallas County Community College District to serve the community in workforce and economic development. The history of the Priest Institute over the last ten years parallels and illustrates the commitment of community colleges nationally to workforce and economic development. The history also reflects similar goals and trends within the state of Texas and, particularly, in the city of Dallas. The Priest Institute is made up of three distinct entities. One entity is the Edmund J. Kahn Job Training Center; another is the Business and Professional Institute, which provides consulting and training services to business clients. The final service area is the complex made up of the regional North Texas Small Business Development Center and its several related local service operations. This study provides an analytical history of each of these components and the process by which they came together in a model facility in Dallas. This study also describes perceptions of persons within the Institute regarding its present mission and purposes and the efficacy of the current organizational structure both internally and within the district operation as an appropriate structure enabling the Institute to meet its …

This study compared the social cognition and object relations of 39 physically abused children to a clinical group of 39 children with no recorded history of abuse.

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.

The Usenet is a global computer conferencing system on which users can affix textual messages under 4500 different categories. It currently has approximately 4,165,000 readers, and these .readers have appropriated language by adapting it to the Usenet's culture and medium. This thesis conceptualizes the Usenet community's appropriation of language, provides insights into how media and media restrictions cause their users to appropriate language, and discusses how future media may further cause users to appropriate language. With the Usenet we have a chance to study a relatively new community bound by relatively new technology, and perhaps we can learn more about the appropriation process by studying the two.

This study was conducted to examine the experience of unwanted sexual aggression from both the male and female perspectives. Questionnaires were distributed to 325 students, and of these, 142 wrote free-response narratives describing their most sexually aggressive experience. Two raters scored and analyzed the narratives on the basis of 19 categories for male responses and 16 categories for female responses. Differences between the male and female perception of the experience of unwanted sexual aggression were found on several categories. The results of this study suggest that date rape awareness and prevention programs should emphasize the point that dating and sexual encounters can easily be fraught with miscommunication and misinterpretation, and encourage clearer communication and better understanding.

Acclimation temperature had a significant effect on the lethality of copper to fathead minnows in replicated 96-hour lethality tests. Lowest median lethal copper concentrations (LC50) were recorded at 12 and 22°C, with LC50s at 5 and 32°C at least 140 μg/1 higher. This research found LC50 copper concentrations in the 300 to 500 μg/1 range and a polynomial relationship between LC50s and acclimation temperature. Following a 24-hour exposure to three sublethal concentrations of copper, critical thermal maxima (CTMax) were tested in minnows acclimated to four temperatures. Sublethal exposure to copper significantly decreased the CTMaxs relative to controls at three of the four temperatures. Control CTMaxs ranged from 28.6 to 40.4°C and increased 0.46°C for each 1°C increase in acclimation temperature.

The enzyme that catalyzes the committed step in pyrimidine biosynthesis, aspartate transcarbamoylase, has been compared in selected endospore-forming organisms and in morphologically similar control organisms. The ATCases and pyrimidine salvage from Sporosarcina ureae, Sporolactobacillus inulinus, Lactobacillus fermentum, and Micrococcus luteus were compared to those of Bacillus subtilis. While the ATCases from Sporosarcina ureae, Sporolactobacillus inulinus, and L. fermentum were found to exhibit characteristics to that of Bacillus with respect to molecular weight and kinetics, M. luteus ATCase was larger at approximately 480 kDa. Furthermore, pyrimidine salvage in Sporosarcina ureae and M. luteus was identical to those of B. subtilis, while pyrimidine salvage of Sporolactobacillus inulinus and L. fermentum resembled that of the pseudomonads.
