Serological Relationships of Azotobacter Species

Serological Relationships of Azotobacter Species

Date: December 1976
Creator: Chang, Chyan-chuu
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

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

Date: December 1976
Creator: Prior, John B.
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

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

Date: December 1976
Creator: Cates, Judy M.
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

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

Date: December 1976
Creator: Ballard, Lynda Dyer
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

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

Date: December 1976
Creator: Richardson, Willie R.
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

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

Date: December 1976
Creator: Sebastian, Jeannie Chaney
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

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

Date: December 1976
Creator: Fuhr, Susan R.
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

Treatment of Migraine Headache Utilizing Cerebral Electrostimulation

Date: December 1976
Creator: England, Ronald R.
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

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

Date: December 1976
Creator: Kirkpatrick, Edwin F.
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

The Wallman Spaces and Compactifications

Date: December 1976
Creator: Liu, Wei-kong
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.

El amor como fuerza motivadora en la vida y obra poética y dramática de Gertrudis Gómez de Avellaneda

El amor como fuerza motivadora en la vida y obra poética y dramática de Gertrudis Gómez de Avellaneda

Date: May 1977
Creator: Milián, Marta Lucrecia
Description: This thesis presents a study of events in the life of Gertrudis Gómez de Avellaneda, a lyric poetess and dramatist during the Romantic period, as motivating forces in her literary career. As might be expected in the case of a true representative of the Romantic period, Avellaneda's passions and personal life are reflected in all of her works. She uses human and divine love as the main themes throughout all of her literary production, especially in her lyric poetry and the four tragedies chosen for this study: Munio Alfonso (1844), El Príncipe de Viana (1844), Saúl (1849), and Baltasar (1858).

Analysis and Evaluation of the Role of Public Relations in Leasing Dallas Petroleum Center

Date: May 1977
Creator: Ainsworth, Doris Stewart
Description: The problem in this study was to discover if the public relations program of the Dallas Petroleum Center was useful in leasing and if the program played a significant role in a leasing increase. The study was carried out by describing the development of the building project, by analyzing the planning and execution of the public relations program, by testing the program's effectiveness, and by drawing conclusions about the program and by making recommendations for this specific program and for office leasing in general. The effectiveness of the program was tested by questionnaires and interviews. The public relations program proved to be an effective tool in leasing office space; and a similar program was recommended for other buildings.

An Analysis of Community Attitudes Toward the "Bowie News" as a News-Advertising Medium

An Analysis of Community Attitudes Toward the "Bowie News" as a News-Advertising Medium

Date: May 1977
Creator: Whitfield, James Daniel
Description: This study measured attitudes of newspaper staff members, advertisers, subscribers, and power structure members toward the Bowie News as a news and advertising medium. Three hypotheses were tested: that members of the power structure would have a more favorable attitude toward the Bowie News than other readers; that the Bowie News would play an active role as an instrument of the power structure; and that all four publics would differ in their perception of the newspaper's role in getting information to the community. The hypotheses were tested by a t test and rejected. Publics' attitudes were homogeneous. It was concluded that the Bowie News reflects consensus opinion within the community and is a trusted news source.

The Applications of Regression Analysis in Auditing and Computer Systems

The Applications of Regression Analysis in Auditing and Computer Systems

Date: May 1977
Creator: Hubbard, Larry D.
Description: This thesis describes regression analysis and shows how it can be used in account auditing and in computer system performance analysis. The study first introduces regression analysis techniques and statistics. Then, the use of regression analysis in auditing to detect "out of line" accounts and to determine audit sample size is discussed. These applications led to the concept of using regression analysis to predict job completion times in a computer system. The feasibility of this application of regression analysis was tested by constructing a predictive model to estimate job completion times using a computer system simulator. The predictive model's performance for the various job streams simulated shows that job completion time prediction is a feasible application for regression analysis.

Association of Masculinity Scores with Five Measures of Adjustment at the Gainesville State School for Delinquent Youths

Association of Masculinity Scores with Five Measures of Adjustment at the Gainesville State School for Delinquent Youths

Date: May 1977
Creator: Kurtz, Howard A.
Description: The problem with which this investigation is concerned is that of determining the effects of masculinity on achievement. The California Psychological Inventory Fe Scale is used to measure masculinity. Results from this scale are compared with results on five measures of adjustment; Wechsler I.Q. scores, the Gainesville State School point system, and three scales constructed for this study to measure aspects of adjustment. The findings of this study fail to support the proposition that masculinity affects adjustment. The instrument used in this study to measure masculinity may be culturally biased. Further research is needed in this area using a number of measures of masculinity to determine masculinity's effects on adjustment.

Automated Testing of Interactive Systems

Automated Testing of Interactive Systems

Date: May 1977
Creator: Cartwright, Stephen C.
Description: Computer systems which interact with human users to collect, update or provide information are growing more complex. Additionally, users are demanding more thorough testing of all computer systems. Because of the complexity and thoroughness required, automation of interactive systems testing is desirable, especially for functional testing. Many currently available testing tools, like program proving, are impractical for testing large systems. The solution presented here is the development of an automated test system which simulates human users. This system incorporates a high-level programming language, ATLIS. ATLIS programs are compiled and interpretively executed. Programs are selected for execution by operator command, and failures are reported to the operator's console. An audit trail of all activity is provided. This solution provides improved efficiency and effectiveness over conventional testing methods.
