A study of the interaction of x-rays and acoustic, stress and shock waves in solids

Description: The primary emphasis of this thesis involves an investigation of techniques for the control and modulation of x-ray radiation through acoustic perturbation of solids. The use of x-ray diffraction and x-ray optical techniques for the study of acoustic fields and atomic motion was also investigated. Analysis of the basic properties of x-ray propagation in solids reveals that practical methods for x-ray control or modulation must involve changes in the spatial configuration of x-ray scatterers. Numerical methods for the study of x-ray propagation in acoustically perturbated crystals are formulated. In developing these methods special emphasis has been placed on Borrmann transmission in thick crystals. Modulation and shuttering (on a micro-second timescale) of x-rays are experimentally demonstrated. A quantitative investigation of the basic interactions used to produce modulation and shuttering is presented. Agreement between the experimental observations and the theoretical predictions is within experimental error. An analytical investigation of the basic potential and limitations of x-ray modulation shuttering and control devices is presented. Basic design criteria for x-ray modulation devices is formulated and applied to practical configurations.

Contingency of Parental Rewards and Punishments as Antecedents of Locus of Control

Description: The study investigated the relationships between perceived contingency of parental rewarding and punishing behaviors and locus. of control. Scores on Levenson's Internal, Powerful Others, and Chance locus of control scales were correlated with scores on Yates, Kennelly, and Cox's (1975) Perceived Contingency of Rewards and Punishments Questionnaire. Few significant correlations were obtained. Maternal non-contingent reward related negatively and significantly to internality for males. Paternal non-contingent reward related positively and significantly to males' perception of control by powerful others. And paternal contingent reward related negatively and significantly to females' perceptions of control by chance. Results are discussed relative to learned helplessness research interpretations.

A Descriptive Study of Value Systems within a School District in Texas

Description: The purpose of this study was to determine the various values that can be found in teachers of an open school system and how those values differed among various teacher groups within the school. The value systems (Tribalistic, Egocentric, Conformist, Manipulative, Sociocentric, and Existential) were based on the "Levels of Psychological Existence" developed by Clare W. Graves. A values test was utilized in order to collect data. The "Values for Teaching Test" was administered to 492 teachers and staff members of the school district. Specific hypotheses regarding value differences in selective teachers and staff groups were tested. The results were significant on the following levels-- existential, sociocentric, and conformist with relation to grade level taught, educational job profile, and sex of the respondent.

The Effect of Ethanol on Cardiac Activity and Brain Respiration in Chick Embryos

Description: This study concerned the effect of ethanol on cardiac activity and brain respiration in chick embryos. Ethanol dosages tested ranged from 1.0 mg to 4.0 mg/g weight. Each experiment lasted at least 150 minutes. Cardiac activity in terms of total waveform energies was integrated and printed out for plotting and analysis. The embryonic heart rates were simultaneously determined from physical graph tracings. The embryonic brain respiration was measured using a differential microrespirometer. The effect of ethanol on cardiac activity was one of slight (10 to 13), but statistically significant (p<.05) rate depression. The brain slices exhibited a marked, immediate, and irreversible decrease (39 to 89%) in oxygen consumption at both ethanol dosages. The data indicated that chick embryonic brain tissues were more susceptible to alcohol effects than cardiac tissue. Therefore, the mental abnormalities seen in the offspring of alcoholic mothers may be more cerebral in nature than cardiovascular.

The Hypothermic Perfusion of the Isolated Thyroid Gland and Its Release of T₃ And T₄

Description: Investigations have shown that the hypothalamus and pituitary respond to decreases in body temperature by stimulating thyroid release of T_3 and T_4 . This study was designed to bypass the control of the hypothalamus and pituitary gland and investigate the direct effect of temperature on the thyroid gland. Hypothermia was by an in vivo isolated perfusion of the thyroid gland. Radio-immunoassay was used to measure T_3 and T_4 concentrations. Significant increases were observed in animals perfused between 36º and 25ºc. These results indicate that the thyroid gland is directly effected by decreased temperature and that it is capable of exerting control over body temperature independent of the hypothalamus and pituitary gland. Lower perfusion temperatures produced no significant increases.

Relationship of Attitudes Toward Mathematics, School, and Teachers to Mathematics Achievement

Description: The present study was designed to investigate the interrelationships of various school-related attitudes and mathematics achievement in a sample of 104 fifth-grade students. A version of the Semantic Differential was used to assess student attitudes toward school, mathematics, teachers, and mathematics teachers. Achievement in mathematics was measured using the Wide Range Achievement Test and classroom grade in mathematics. Higher correlations between the attitude and achievement variables were obtained when classroom grade was used as the achievement measure. Weights generated for each of the attitude variables in multiple regression equations designed to predict each achievement measure were nonsignificant for males, females, and the total sample. Results were discussed and recommendations for future research were made.

The Effect of Response-Contingent Positive Stimulation of the Frequency of Intervals of Specified Fluent Verbal Behavior of Stutterers

Description: Intervals of specified fluent verbal behavior of two stutterers received response-contingent positive stimulation in the form of an accumulating points system, Assessment was made o the effect of experimental manipulation on the frequency of fluent speech intervals as well as on the frequency of subject-identified stuttering behaviors observed during the experimental session. The results indicated significant change in fluent interval frequency in the spontaneous speech of one subject. Effect of the experimental contingency was not demonstrated in the oral reading of a second subject. Stuttering. behavior data indicated that an indirect effect of the positive stimulation can change the frequency of behavior not being contingently stimulated.

Generating Machine Code for High-Level Programming Languages

Description: The purpose of this research was to investigate the generation of machine code from high-level programming language. The following steps were undertaken: 1) Choose a high-level programming language as the source language and a computer as the target computer. 2) Examine all stages during the compiling of a high-level programming language and all data sets involved in the compilation. 3) Discover the mechanism for generating machine code and the mechanism to generate more efficient machine code from the language. 3) Construct an algorithm for generating machine code for the target computer. The results suggest that compiler is best implemented in a high-level programming language, and that SCANNER and PARSER should be independent of target representations, if possible.

Dietary Treatment of Hyperactive Children

Description: This study investigated whether a salicylate-restricted diet (eliminating foods containing artificial additives and natural salicylates) could effectively reduce hyperactivity in children more so than a diet not restricting salicylates (ostensibly restricting foods containing refined sugar). Ten hyperactive children, nine boys and one girl, were matched on their pre-treatment activity rates and assigned to either a salicylate-restricted diet (Group I) or a diet not restricting salicylates (Group II). After approximately nine weeks, post-treatment activity rates were obtained, and a significant difference in favor of the salicylate-restricted diet group was found with this diet group exhibiting a significantly lower mean post-treatment activity rate in comparison to the group placed on a diet not restricting salicylates (p<.05). Implications for diagnosis and treatment of hyperactivity in children were discussed.

The Novelist as Critic: Thackeray's Concept of the Novel

Description: This study is primarily concerned with the formulation of Thackeray's theory of the novel through a thorough investigation of his various reviews and critiques of Victorian fiction which appeared in periodicals and by a careful examination of his letters, By evaluating the numerous comments on particular works of fiction and on the art of "novel-spinning" in general which came from Thackeray's pen, this study investigates the various Thackerayan ideas as to how novels should be written with regard to the function of the novel, the formulation of plot and character, realism and morality, the presentation of description, and the style in which novels were to be written. This investigation concludes that Thackeray's theory of the novel was that novels were to be written in a simple, straightforward style and were to present "living" characters who performed realistic, believable actions within tightly unified, logical plots in such a manner as to provide entertainment and to reaffirm the Victorian moral code.

The Development of an Art I Curriculum Guide for the Mesquite Independent School District

Description: This study reports on the development of a curriculum guide to insure some degree of experience uniformity in the first art course available to students in high schools in Mesquite, Texas. Current general education and art education literature as well as curriculum guides from American schools provided the behaviorally oriented framework and objectives, content, and teaching strategies. The guide reflects a balance between the ideal and the real physical environment in which the guide will be implemented. Conclusions include the concepts that teacher education in using behavioral objectives is necessary, that a behaviorally oriented guide will work in Mesquite high schools, that behavioral objectives will facilitate evaluation, and that the trend toward tri-part subject content will increase in art curricula.

La Temática Poética de Julián del Casal

Description: This thesis studies three of the most significant themes in the poetry of the Cuban Modernist, Julian del Casal. The poet's morbid fascination with death is characterized by an inability to adapt to his life environment, boredom, a strong self-destructive drive, and the concept of death as the ultimate joy and refuge. He reflects the Modernist aesthetic code in his cult of plastic and lyric beauty. An escapist, he sought refuge in an ideal world of perfection and elegance. This unobtainable goal resulted in deep melancholia and despair. The theme of love reflects a complete absence of passion and eroticism. The poet's categorical rejection of woman as a sensual object is accompanied by subtle insinuations concerning his own physical impotence and inability to love.

Irish Members of Parliament and the Home-Rule Bill of 1912

Description: This thesis examines speeches made by Irish members of the British House of Commons concerning the Government of Ireland Bill (1912). The most significant source use was the Parliamentary Debates of the House of Commons, 1912 to 1914. The organization of the Irish political parties is outlined in Chapter One. The next two chapters deal with their view of Irish history during the eighteenth and nineteenth centuries. The fourth chapter focuses upon the bill in committee, and the fifth chapter examines the more general debate on the bill. The conclusions of the final chapter suggest that advocates of the bill were motivated by Irish nationalism, while opponents were motivated by economic ties to Great Britain.

A Survey of Parental Decision-Making Regarding Preschool Programs for Four-Year-Old Children

Description: The study was an investigation of parental decision-making regarding preschool programs for their children. Data indicated that parents investigated a preschool program beyond a conversation with the preschool director and that non-educational aspects of preschool programs were important considerations in the selection of a preschool program by parents. Parents educational preferences tended to coincide with the educational programs of the preschools they selected, although parents indicated favorable opinions of more educational variables than any of the preschools surveyed offered. Levels of education attained by mothers appeared to have little effect on educational preferences, and parents whose first child was attending preschool had educational preferences similar to those of parents whose older children had attended preschool.

A Study of George McGovern's Rhetorical Strategy in Handling the Eagleton Affair

Description: The purpose of this study was to describe and analyze George McGovern's rhetorical strategies during the three-week period known as the "Eagleton Affair." First, the thesis describes the communications related to the selection of Thomas Eagleton as McGovern's running mate in 1972. Second, it analyzes the communications related to the disclosure of Eagleton's past medical history. Third, it explains McGovern's vacillating rhetorical strategies and the communications which led to Eagleton's withdrawal from the Democratic ticket. The results of this study show that McGovern's rhetoric reflected indecisiveness, inconsistency, and impulsiveness. The rhetorical errors greatly damaged his credibility as a serious presidential contender.

The Spinster and Flabby Lucy

Description: Many contemporary writers maintain that a prime requisite of poetry is autobiographical sincerity. They would have the poet commit himself to an openness with his audience that is usually reserved for only the most intimate relationships. The thirty-two poems of this thesis were written as a reaction to current confessional trends and postulate that the creation of fictions to live by is an intrinsic part of the human process. Central to the work is the idea that past fictions, traditions, and myths are no longer functional, and no workable fictions have yet been created. The overriding image of the work is that of a dance in a mirrored room where illusion and reflection are difficult to separate from reality and where the dancers move without knowledge of the meaning of their movement.

Employment of the Rorschach Inkblot Test with the Devries Suicide Inventory

Description: This investigation represents an attempt to employ the Devries Suicide Prediction Scale and the Rorschach Inkblot Test in a two-stage predictive model which was designed to decrease the high false positive rate associated with the Devries and to design a way in which the Rorschach could be used efficiently in suicide prediction in a large mental hospital setting. The Rorschach was not found to significantly improve the predictive ability of the Devries. An unexpectedly high percentage of mental patients in the study, thirty-eight percent, admitted to previous suicide attempts, raising the question of whether suicidal behavior is not more common than is usually thought.
