Physiological Studies of the Bdellovibrio-Host Interaction

Description: The purpose of this study was to focus attention on the physiology of the bdellovibrio-host interaction and to determine the metabolic requirements for this reaction. Since bdellovibrio is an aerobic organism, direct measurements of respiration, turbidity, and viable cell counts are reliable indications of the metabolic activity of the cells. It was determined that the metabolic requirements for the parasitic interaction are constituents from either metabolically active host cells or cells which are capable of at least some metabolic activity. The nutritional requirements of host-independent bdellovibrios suspended in buffer are not met by the presence or absence of viable or nonviable Enterobacter aegnes. Unlike the HD bdellovibrios, the HI bdellovibrios lack the ability to make economical use of their self-digesting processes.

The Posthumous Narrative Poems of C. S. Lewis

Description: The purpose of this study is to introduce the three posthumous narrative poems of C. S. Lewis. Chapter One is an introduction to Lewis's life and scholarship. The second chapter is concerned with "Launcelot," in which the central theme of the story explores the effect of the Quest for the Holy Grail on King Arthur's kingdom. Chapter Three studies "The Nameless Isle," in which Celtic and Greek mythic elements strongly influence both characterization and plot. The fourth chapter is an analysis of The Queen of Drum and its triangular plot structure in which the motivating impetus of the characters is the result of dreams. Chapter Five recapitulates Lewis's perspectives of life and reviews the impact of his Christianity on the poems. The study also shows how each poem illustrates a separate aspect of the cosmic quest.

Project Redeployment: A Financial Innovation, a Case Study of LTV

Description: The purpose of this study was to examine the aspects of redeployment in general terms, and then to present a case study of a specific redeployment program to analyze its effectiveness as a corporate financial tool. The first four chapters discuss the general and financial definitions of redeployment, as well as the objectives, benefits, and alternate methods of the operational asset form of redeployment. The specific redeployment program analyzed is the case study of Ling-Temco-Vought's use of the operational asset form of redeployment. The purpose of the case study was to determine if Ling-Temco--Vought achieved their stated objectives. An analysis of these objectives shows that redeployment was a success.

Relationship Between Personality Characteristics of Incarcerated Juvenile Delinquents as Measured by the MMPQ and Specific Behavior Criteria

Description: The purpose of the present study was to determine whether or not significant correlations could be obtained between raw scores on fifty-three scales of the Mini-Mult Prison Questionnaire (MMPQ), a personality test, and nine selected behavior variables for a group of thirty-two institutionalized male delinquents. A correlation matrix using Pearson's r revealed that seven MMPQ scales correlated at the p = .05 level of significance with the behavior criteria. Thus, four of the five hypotheses formulated were supported. However, caution was emphasized in interpreting the results due to sample size, sample homogeneity, and the dissimilarity of the adolescent sample from the adult prison population on which the MMPQ was developed.

A Self-Control Approach to Weight Control

Description: A strategy for facilitating post-treatment weight maintenance was examined. Subjects were matched for age, sex, and amount of weight that they desired to lose and were then assigned to one of two groups. Both groups were under contracts and had individually designed self-control programs for weight loss, but subjects in the experimental group lost weight in small steps and subjects in the control group lost weight continuously. The experimental group was predicted to have better weight maintenance after treatment because of a greater number of reinforcements for weight loss. Two-month follow-up data was obtained on the ten subjects who completed the study, and the experimental group was found to have regained significantly less than the control group after treatment ended. The implications of these results for obesity research are discussed.

Serological Relationships of Azotobacter Species

Description: In order to clarify the taxonomic problems which exist among the group azotobacter by serological method, 24 cultures of Azotobacter including 9 species were tested as antigens in Ouchterlony plates against 3 different antisera obtained from rabbits immunized with A. chroococcum ACl6, A. macrocytogenes St.M. and A. vinelandii 12837, respectively. The results showed more cross reactivity in intraspecies reactions than in interspecies ones and indicated the presence of a common immunogenic determinant. This work presents the results which suggest the effecient classification of Azotobacter by Ouchterlony comparisons of corresponding antigens in different species.

A Study of George Canning's Sustained Campaign for the Recognition of Latin America from 1822-1826

Description: This thesis analyzes George Canning's persuasive campaign to gain British recognition of Latin America. The modification of an exigence capable of change through persuasion was emphasized, and the audiences which had the power to bring about the change were identified. The campaign was broken into seven discernible, but dependent, stages which were examined to test the progress of the campaign. Canning was the prime mover of the campaign, and through a series of petitions, speeches, and press releases plus other strategic maneuvers, gained the necessary public and political support to successfully achieve his goal.

A Study of the Attitudes of Journalism Students in Dallas High Schools Toward Journalism Careers

Description: The purpose of this study was to examine the attitudes of journalism students in Dallas high schools toward the meanings and images of journalism careers. Eleven out of eighteen Dallas high schools participated. A total of 211 respondents, 145 females and 66 males, completed the questionnaire. The first part of the analysis involved the comparison through percentage tables illustrating the similarities and differences of the groups. The second part of the analysis involved the semantic differential scales and the mean profile comparisons for the groups. Although the seven branches of journalism did differ significantly from one another, the male and female subjects did not differ significantly in their meanings of the concepts.

A Study of the Impact of Junior High or Middle School Forensic Training on High School Forensic Programs in the Dallas-Fort Worth Metroplex

Description: The purpose of this thesis is to determine the impact of intermediate school forensics on high school forensic programs in the Dallas-Fort Worth metroplex. First, the thesis records student and instructor evaluations of both the intermediate school and high school forensic programs. Second, it compares the evaluations by students with intermediate forensics and students without intermediate forensics. Third, it discusses the impact of intermediate forensics on high school forensic programs. This study reveals that intermediate forensics is beneficial to high school forensics. Previously trained students teach and interest others in high school. They are more confident, have more initiative and win more than other students.

A Study of the Relationships Between Grip Strength, Wrist Flexion, Arm Length and the Velocity of a Thrown Baseball in Male High School Varsity Baseball Players

Description: This study analyzed the relationships present between grip strength, wrist flexion, arm length, partial and total, and throwing velocity. Thirty-one subjects were tested to obtain the data on these variables. A multiple linear regression equation produced a significant F ratio for the relationship between grip strength and throwing velocity. Neither wrist flexion nor arm length obtained a significant F ratio to throwing velocity. A stepwise multiple regression equation again displayed a significant F ratio for grip strength and throwing velocity. Wrist flexion and arm length did not produce a significant F ratio for their relationships to throwing velocity. This study concludes that of the variables tested, only grip strength displayed a significant relationship to throwing velocity. This study indicates that throwing velocity can be predicted at a moderate level from the measurement of grip strength.

Symbolism in Afro-American Slave Songs in the Pre-Civil War South

Description: This thesis examines the symbolism of thirty-five slave songs that existed in the pre-Civil War South in the United States in order to gain a more profound insight into the values of the slaves. The songs chosen were representative of the 300 songs reviewed. The methodology used in the analysis was adapted from Ralph K. White's "Value Analysis: The Nature and Use of the Method." The slave songs provided the slaves with an opportunity to express their feelings on matters they deemed important, often by using Biblical symbols to "mask" the true meanings of their songs from whites. The major values of the slaves as found in their songs were independence, justice, determination, religion, hope, family love, and group unity.

Theories Contrasted: Rudy's Variability in the Associative Process (V.A.P.) and Martin's Encoding Variability

Description: A paired-associate list of three-word stimuli and one-word responses comprised the first list of an A-B, A-Br paradigm. Each of the three words from the first-list three-word stimuli was singly re-paired with first-list responses to make up three of the second-list conditions. The fourth second-list condition used the first-list stimuli plus re-paired first-list responses. Results obtained were that: (a) nine of the sixteen subjects spontaneously shifted encoding cues from first to second lists, (b) evidence of significantly greater negative transfer occurred only in the A-B, A1 2 3-Br condition, and (c) although not attaining significance level, across all A -Br conditions there were more errors on second-list learning for those not shifting encoding cues from first to second list. For those who did shift, performance was only slightly lower than the A-B, C-B control condition. Neither the encoding variability nor the associative variability theory was entirely supported. A gestalt interpretation was suggested.

Treatment of Migraine Headache Utilizing Cerebral Electrostimulation

Description: Cerebral electrostimulation (CES) as a treatment for migraine headache was investigated. Eighteen participants recorded data on headaches for two baseline weeks. Six were assigned to each of three groups--an active treatment group receiving CES, a placebo group receiving a simulated version of CES, and a no-treatment control group placed on a waiting list during the study. The CES group evidenced a significant reduction in headache duration and intensity relative to the placebo group. The waiting list control group did as well as the CES group. A number of hypotheses were put forth in an attempt to account for the unexpected finding.

The Use of Closed Circuit Television as an Implement of Industrial Security

Description: The problem of this study was to determine to what extent industry was making use of closed circuit television as an implement of industrial security. The data for this study were provided by a group of thirty-two security chiefs of industry, and by another group of fifteen law enforcement officials in the Dallas and Fort Worth Metropolitan area. Of those industrial concerns making use of closed circuit television as an aid to security, a majority use the medium for surveillance of controlled access areas, with theft control and control of plant access following closely behind. For the most part, all surveyed thought that closed circuit television was very efficient.

The Wallman Spaces and Compactifications

Description: If X is a topological space and Y is a ring of closed sets, then a necessary and sufficient condition for the Wallman space W(X,F) to be a compactification of X is that X be T1 andYF separating. A necessary and sufficient condition for a Wallman compactification to be Hausdoff is that F be a normal base. As a result, not all T, compactifications can be of Wallman type. One point and finite Hausdorff compactifications are of Wallman type.
