This investigation dealt with locating and measuring x-ray absorption of radiographic images. The methods developed provide a fast, accurate, minicomputer control, for analysis of embedded objects. A PDP/8 computer system was interfaced with a Joyce Loebl 3CS Microdensitometer and a Leeds & Northrup Recorder. Proposed algorithms for bone location and data smoothing work on a twelve-bit minicomputer. Designs of a software control program and operational procedure are presented. The filter made wedge and limb scans monotonic from minima to maxima. It was tested for various convoluted intervals. Ability to resmooth the same data in multiple passes was tested. An interval size of fifteen works well in one pass.

The purpose of this thesis is to study Thailand's foreign relations. The specific argument will be that, to a large extent, Thailand was able to keep her independence because of her rulers' ability to adapt the country's policy to the changing circumstances in foreign affairs. Therefore, it was imperative for policymakers to look at the threats to the country's security from the local point of view and to develop appropriate policies for dealing with them accordingly. The thesis is organized into six chapters. After the introductory chapter, the second and third chapters examine the historical development and the general features of the foreign relations of Thailand, respectively. Chapter Four deals with the change in the direction of foreign policy after the Second World War. In contrast to the traditional foreign policy, the government under military dictatorship gradually moved in the direction of the Western, especially American, position. The positive and negative consequences of the pro-American policy are treated in Chapter Five, It is pointed out that this policy contributed to the sharp increase in activity of Communist insurgents in various parts of the country. By comparing the post-war foreign policy with the traditional policy prior to that time, a conclusion …

The following research questions were investigated: (a) Can the age-mates scales from the Dales developmental task scales be used with southwestern-urban adolescent populations? (b) Are there any systematic differences between northeastern-nonurban and southwestern-urban subject populations on the response to these scales? The subjects consisted of 884 adolescents, 11 through 15 years, evenly divided by sex. Subject responses were analyzed by sex and age groups using Guttman scalogram analysis. Goodman's test of significance revealed that the results could have occurred by chance (p > .05). The instrument in its present form was not found useful'-for an urban population. Lack of reproducibility made comparison of the performance of urban and nonurban adolescents unjustified.

Factors which influence severity of moral judgement in men and women were investigated in this study with 94 male and 89 female undergraduate students as participants. Effects of "sex of judge," "sex of transgressor," and "value orientation" variables were examined across five diverse story conditions. A measure of identification was also obtained. As hypothesized, a significant main effect was found for "value orientation," but not for "sex of judge" or "sex of transgressor" variables. The hypothesized disappearance of a "sex of judge" by "sex of transgressor" interaction was found. Hypotheses concerning a permissive trend and the effects of degree of identification were not confirmed.

As a painter, I have been working the past few years to develop a mature pictoral image and the concepts of space that were flexible enough for me to produce what I believed was a valid art statement. I have investigated several avenues for improving my work, i.e., acquiring certain technical painting skills, reading more to broaden my concepts and imagination, and visiting various art galleries and museums. During an earlier critique it was realized that the majority of my paintings were all very similar in scale. I decided to approach my work on a much larger scale than previously attempted in the hopes of discovering a better, or at least different painting concept.

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.

This study investigated relationships involving peer acceptance, mathematics achievement, and birth order among 74 fifth-grade students. The children were administered a standardized achievement test and a sociometric measurement in one sitting. They were then listed in rank order on the basis of number of choices received for each of two areas-- Social- and Work-acceptance. A comparison of High and Low Social- and Work-acceptance groups in terms of mean mathematics-achievement scores indicated a significant positive interaction between peer acceptance and mathematics achievement. No significant difference was evidenced between mean mathematics-achievement scores of males and females. As expected, birth order was not shown to interact significantly with Social- or Work-acceptance for either sex. Results indicate the importance of utilizing various techniques such as sociometrically determined work groups and seating arrangements in order to improve the peer climate of the classroom.

This thesis includes two background chapters based largely on secondary works; Chapters I and II trace the historiography of black participation in American military engagements from the American Revolution through the Korean conflict. Chapter III, based largely on primary sources, places emphasis on black resistance and attitudes toward the Vietnam crisis. Evidence indicates that the Vietnam era of black protest was not unique but was an evolutionary process that had its roots in other periods in American history. Some blacks questioned their involvement in each American military conflict from the American Revolution to Vietnam.

The problem was to design and construct the necessary equipment to cut and fasten short stock end to end using finger-joints. The study was divided into five chapters: I contained the introduction to the problem; II was concerned with the design and construction of the equipment; III detailed the operation of the equipment; IV contained the presentation of the data; and V covered the summary and findings. The study concluded that the equipment could be constructed inexpensively, and would perform a useful service. Also, a student using waste wood salvaged through use of this equipment could expect a smaller bill for materials than if he purchased new wood.

This study is concerned with the dramaturgic use of the fools of five of Shakespeare's plays. After the Introduction, Chapter II investigates the fool as a historical figure and establishes his credibility. Chapter III examines the comic methods and techniques of the fools. Chapter IV is an investigation of the use of the fool in his capacity as choric voice to present a particular viewpoint on the play. Chapter V is a study of how the fool fits into the action as a character, and Chapter VI investigates the ways in which he may be used in structural duties. The study concludes that the Shakespearean fool is an effective device due to his historical credibility and his recognized position as an entertainer.

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.

Responses of 111 doctoral clinical psychology students to Garfield and Kurtz' (1973) Testing Attitude Scale were subjected to a 2 x 2 factorial analysis. Attitudes toward psychodiagnostic testing were found to be related both to academic versus nonacademic professional expectations (academics scoring more negatively, M = 32.69, than nonacademics, M = 37.19), F (1, 107) = 5.994, p < 0.016, and to internship training exposure (non-interns scoring more negatively, M = 34.64, than interns, M = 38.80), F (1, 107) = 10.321, p< 0.002. Results paralleled previous research on academic and nonacademic working psychologists' attitudes. Similarities in students' and role models' attitudes were discussed in terms of Kelman's (1953; 1958), Festinger's (1957), and Bem's (1970) attitude theories. Results seemed to imply continued controversy over both the desirability of producing psychodiagnostically oriented clinicians, and also traditional paradigms of psychodiagnostic training.

The thesis states that the confidant in the tragedies of Jean Baptist Racine evolves from the traditional servant figure to a sophisticated intimate of the principal character. The confidant's identity becomes synonymous with that of the principal character: he appears as his alter ego. The sources used are six of Racine's secular tragedies, in addition to critical works and essays of his writings. The tragedies included in this study are La Thebaide, whose secondary characters serve as a comparison to the more developed confidants as found in Andromaque, B /r/nice, Mithridate, Britannicus, and Phedre. Racine presents a variety of tragic characters whose multifaceted personality emerges through the intervention of their confidant. Representing one side of the protagonist's character, or his "other self, " the confidant becomes Racine's dramatic tool to portray the internal struggle in all its aspects. Racine's preoccupation with moral issues and his desire to instruct his audience pervade his writings. It is thus possible to trace the development of the confidant from his part as self-effacing messenger to his role as alter ego to the principal figure where he dramatically demonstrates the tragic, inner division of man.

Gut contents of 2,500 stonefly nymphs, comprising 10 species, from the Gunnison and Dolores Rivers, Colorado were examined from Dec., 1974-Oct., 1975. Perlidae species were carnivorous feeding primarily on chironomids, mayflies and caddisflies. Seasonal patterns of ingestion and preference varied among species and predator sizes and between rivers. Early instar polyphagous species utilized detritus in the fall, eventually shifting to carnivorous habits as they grew through winter-spring. Pteronarcids fed predominantly on detritus. Dietary overlap of predators was greatest in the Gunnison River, with subtle mechanisms such as prey species and size selectivity, temporal succession and seasonal shifts to detritus-plant material in some, providing reduction of competition. A more complete partitioning of prey resources was evident in the Dolores River.

This thesis attempts to discover the basis of Chesterton's theories and the link between his religion and politics. The main sources for this paper are the religious and political non-fiction works by Chesterton and his collaborators. The first chapter brings G. K. from his birth in 1874 to 1908 and the publication of Orthodoxy. The second chapter describes his conversion to Roman Catholicism, and the third discusses his distinctive Christian theology. The fourth outlines G. K.'s political solution for Englands economic and social ills and how his theory--distributism-- fit into British intellectual tradition. The conclusion identifies G. K.'s romance with the Middle Ages as the link between his religious beliefs and his political utopia.

This study was made to find the effects of noise on the human body, to measure sound levels that exist in school power laboratories, and to design and evaluate the effectiveness of two noise control devices. An accurately calibrated testing device was used to measure sound levels in an attempt to determine if excessive noise exists in school power laboratories and to find the extent to which such noise can be reduced by shielding or enclosing the engine test area. It was found that noise has undesirable physical and psychological effects on the human organism. Sixty-two and one-half per cent of the engines tested registered sound levels above 90 dBA; even so, simple, inexpensive noise control devices do control the noise levels generated in the school power laboratories.

In early Victorian England, the new philosophy of social democracy challenged the bourgeois creed of laissezfaire. An important aspect of this struggle, which historians have neglected, is the campaign (1831-1853) for a shorter and regulated factory workday. This study concludes that during the Parliamentary debates on factory legislation, Britain's leaders, regardless of party affiliation, decided that the Government, indeed, had an obligation to assist the victims of social and economic injustice, a decision which meant the end of laissez-faire.

Drumming was recorded for 11 of 13 Nearctic stonefly species, representing 4 families. Both male and female signals were obtained from 5 species, and were either 2-way or 3-way communications. Signals were species-specific; those of males and females varied from 3-39 and 1-14 beats/ signal, respectively. Duration of male signals varied from 105-8,016 ms; those of females, except Perlinella drymo (1 beat), varied from 402-1318 ms. Signals among related taxa showed greatest similarities. Duration of male signals of Perlinella drymo became progressively shorter at each of 4 temperatures from 7-29 0C. Females of Perlinella drymo would only repeatedly answer male signals recorded at near their own temperature, and would not repeatedly answer recorded male signals of 8 other species.

The purpose of this study was to test the applicability of the theories of selective perception and selective exposure among ethnic minority viewers of the satirical, ethnic humor of the television program, "All in the Family." This study statistically related the Dogmatism Scale responses to selected program opinions among Jewish and non-Jewish high school students. The results of this survey were inconclusive. None of the hypotheses presented were supported by the evidence of the study; however, unexpected data were found that suggests previously unexplored interpretations of the program.

This is an original, serious, three-act play for eleven characters. The drama focuses on a group therapy situation involving three women patients, two men patients, and their therapist. Flashbacks are utilized to provide knowledge of the characters' pasts. Role playing, dream analysis, and behavior modification are some of the tools employed by the counselor. While the therapist does utilize these techniques adequately, his own personal problems prevent him from being as effective as he might be. Consequently, at least two of the characters are propelled to their own destruction, possibly as a result of the therapist's failure. Of course, the possibility does remain that they would have chosen the same paths without the counselor's influence.

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 questions arising over the deterioration of the 0BD have brought this topic to the attention of the public. This thesis will discuss the Central Business District of D311a5 and its decline.

The purpose of this paper is to establish a need for more accessible fine arts courses offered to adults and more specifically in music, to design a series of programs that would give an introduction to beginning functional piano through the use of educational television. The paper includes ten lesson outlines for thirty minute program segments including a pilot script. This educational television series is designed to stimulate the student's continued playing of the piano with guided instruction through class or private lessons. A particular method of piano pedagogy used for educational television is explored. Procedures followed in order to be able to film the project are also covered, It is suggested that a survey in the particular viewing audience area be conducted and tests given to a cross-section of adults before implementation of the program.
