Although President Theodore Roosevelt intervened in the Dominican Republic in 1905 to prevent European creditor nations from securing a foothold at the Atlantic entrance to the Panama Canal, the idea persists among certain historians that Roosevelt's motives for intervention were primarily economic, not political. A close examination of Dominican economic history from the inauguration in 1882 of the tyrannical President Ulises Heureaux, combined with a study of American diplomacy toward the Dominican Republic to the initiation of the customs receivership in 1907, demonstrates that American policy attempted to thwart outside intervention, not promote economic subversion. Best primary sources are the State Department's Diplomatic Instructions, 1801-1906; the Despatches, 1883-1906; and Jacob H. Hollander's "Report" and "Exhibits." Excellent secondary sources are Dana G. MIunro's Caribbean studies.

This study is concerned with describing and analyzing the factors that led to the election and subsequent defeat of Salvador Allende. The research information was selected from leading books, periodicals, government documents, archives, and newspapers. The thesis presents the political history of Allende's rise to power, the social structure that made his victory possible, the development of major programs that facilitated his ascension and that made his decision inevitable, and, finally, an analysis of his administration with observations as to why he failed. The importance of the lower class, the middle class, the military, and the United States are presented as factors contributing to Allende's victory and later accelerating Allende's fall from power.

This study examines and analyzes the treatment accorded Alger Hiss by the American press from August 3, 1948, to January 25, 1950. Information sources included the forty-one newspaper articles submitted by Hiss's attorneys in their motion for a change of venue at the second trial, and those sections of books, newspapers, and magazine articles relative to the press's coverage of the case. Six chapters cover the changing press image of Hiss, newspaper articles submitted in evidence, and the relationships of Richard M. Nixon and Whittaker Chambers to the press. The study analyzes historically the differing attitudes toward Hiss and concludes that since the press reflected the nation's fears that its leaders had Communist ties, press coverage of the case lessened Hiss's chances for a fair trial.

The problem investigated is that of determining if there are differences in the ability of mentally retarded persons over age 21 to learn motor skills as opposed to those under 21. Data were gathered at the Denton State School on 110 subjects. The first chapter is concerned with the theoretical background, purpose, and the hypothesis. The second chapter contains information on subjects, materials, method, and statistical treatment. The third chapter covers presentation and discussion of the data, and the fourth chapter includes the summary, conclusions and recommendations. Results of the study indicated that there were few differences between the two groups. Future studies should be run with samples from individual age groups extending from 6 through 21. This would be realistic in establishing a motor learning curve for this population.

The problem of this study was to determine the professional preparation, playing experience, and involvement in professional organizations of secondary school coaches in Northeast Texas. This information was presented in such a manner that comparisons might be made with recommendations for certification of high school coaches by the American Association for Health, Physical Education and Recreation. The findings of the study seem to warrant several basic conclusions. Degree requirements, playing experience, and professional activities of the coaches appeared adequate. The coaches' professional preparation in physical education seemed inadequate according to the recommendations for certification.

This investigation attempts to uncover a unity of both meaning and technique as reflected in eight of Katherine Anne Porter's best known and most characteristic stories-- "Old Mortality," "Noon Wine," "Pale Horse, Pale Rider," "Flowering Judas," "A Day's Work," "The Cracked Looking-Glass," "He," and "Holiday." An analysis of each story reveals that the core of Katherine Anne Porter's work is a "delicate balancing of rival considerations" specifically and deliberately designed to reveal to the reader the complexity and ambiguity of any situation or human relationship. The ambiguity within her stories is therefore deliberate. The final chapter, "The Open End and the Acceptance of Paradox," asserts that Katherine Anne Porter's technique is determined not by her classical conception of literary form, but by her philosophy of life.

Thirty-one college age females enrolled in aerobic dance conditioning classes were subjects. The purposes were to determine if aerobic dance is sufficiently vigorous to elicit a heart rate capable of producing a training effect and to determine whether a training effect heart rate level can be maintained. The narco-biosystems telemetry was used to monitor heart rates. Each subject performed one aerobic dance at three trials. Twelve-minute run/walk pretests and post-tests were given to assign fitness levels. Results of the study indicate that aerobic dance is an effective cardiovascular training program. Resting heart rates decreased, fitness levels improved, and training intensity heart rates were elicited and maintained at each of the trials.

This investigation deals with the underlying motivation of Oswald Spengler in The Decline of the West. Sources include the published and translated works of Spengler: books, essays, and selected letters. Contingent areas of exploration, arranged in separate chapters, are the philosophy of history, using the works of Dilthey and Herder; philosophy, using the concepts of Husserl's Phenomenology, Bergson's Time and Free Will, and Goethe's Conversations with Eckermann; the contemporary human potential psychology of Abraham Mazlow and Rollo May, and the contemporary philosophy of Alan Watts and Ortega y Gasset. R. G. Collingwood as critic of Spengler is dealt with. The conclusion is drawn that Spengler did not attempt a system of history except as a vehicle for expressing a directive to live fully in the eternal now.

This study compares the May, 1974 and May, 1975 editions of suburban daily newspapers in the Dallas-Fort Worth metroplex. The purposes of the study were to determine how, when, and why suburban daily newspapers in the metroplex altered their editorial content and to evaluate the effects of the changes on circulation. The thesis is organized into four chapters. Chapter I introduces the study. Chapter II gives a historical overview. Chapter III analyzes the data. Chapter IV contains some conclusions. Some conclusions that emerged from this study include: 1. Suburban newspapers have small editorial staf fs. 2. Eight of the newspapers altered their content. 3. The changes helped them maintain or increase their circulation. 4. All of the editors responding to the questionnaire said that local news and sports are their primary goals.

This research demonstrates that experience with uncontrollable reinforcement, here defined as continuous non-contingent positive feedback to solution attempts of insoluble problems, fails to produce the proactive interference phenomenon, learned helplessness, while uncontrollable aversive events, here defined as negative feedback to solution attempts of insoluble problems, produces that phenomenon. These results partially support the "learned helplessness" hypothesis of Seligman (1975) which predicts that experience with uncontrollable reinforcement, the offset of negative events or the onset of positive ones, results in learning that responding is independent of reinforcement and that learning transfers to subsequent situations. This research further demonstrates that experience with controllability, here defined as solubility, results in enhanced competence.

This study analyzes the themes of victimization and self-sacrifice as they appear in the life and works of Oscar Wilde. "Victimization" is defined as an instance in which one character disregards, damages, or destroys another's well-being; "self-sacrifice" is an instance in which one character acts to his own detriment in order to help another or through dedication to a cause or belief. Chapter I discusses the way in which these concepts affected Wilde's personal life. Chapters II-VI discuss their inclusion in his romantic/decadent dramas, social comedies, various stories and tales, novel, and final poem; and Chapter VII concludes by demonstrating the overall tone of charitable morality that these two themes create in Wilde's work as a whole.

This thesis reports the synthesis and characterization of two new copper(II) halide complexes with deprotonated N-(2-hydroxyethyl)ethylenediamine behaving as a bidentate. The magnetic properties of the new copper(II) complexes were studied from room temperature to liquid nitrogen temperatures. The magnetic data show that both complexes exhibit antiferromagnetic interactions with a singlet ground state and a thermally accessible triplet excited state. Magnetic data and infrared spectra indicate the complexes are halogenbridged. Deprotonation at an amine nitrogen is based on the presence of a hydroxyl stretching band in the infrared spectra. Electronic spectra and infrared spectra indicate the complexes are square planar. Elemental analyses, infrared spectra, electronic spectra, electron spin resonance spectra, and magnetic data are reported and discussed.

Greatest common divisor domains, Bezout domains, valuation rings, and Prüfer domains are studied. Chapter One gives a brief introduction, statements of definitions, and statements of theorems without proof. In Chapter Two theorems about greatest common divisor domains and characterizations of Bezout domains, valuation rings, and Prüfer domains are proved. Also included are characterizations of a flat overring. Some of the results are that an integral domain is a Prüfer domain if and only if every overring is flat and that every overring of a Prüfer domain is a Prüfer domain.

The synthesis and characterization of two new Schiff base copper(II) complexes are reported. These are Cu(acac: 2-amino-l-phenylethanol) and Cu(acac:2-amino-l-butanol). The ligands, derived from acetylacetone and the appropriate aminoalcohol, are dibasic tridentates with 0,N,O donor atoms. The magnetic properties of the complexes were studied at several temperatures between 78 OK and 296 OK. The magnetic moment of Cu(acac:2-amino-l-phenylethanol) varied little with temperature, and that of Cu(acac:2-amino-lbutanol) increased as the temperature was lowered. This is in contrast to the magnetic moment of Cu(acac:ethanolamine), which decreases as the temperature decreases. Molecular weight data, infrared spectra, magnetic data, electronic spectra, and electron spin resonance spectra of both complexes are reported and discussed.

The Purpose of this study was to investigate the relationship of the repression-sensitization dimension and leisure preferences, specifically threatening versus nonthreatening physical activity and television program preferences. The hypotheses were that sensitizers would prefer threatening (violent) television programs and threatening (competitive) physical activities to a significantly greater degree than repressors. Sixty college undergraduates were designated repressors, sensitizers, or middle group by their scores on Byrne's Repression-Sensitization Scale. Preference sheets determined subjects' preferences for threatening and nonthreatening television programs and physical activities. Simple analyses of variance revealed no significant differences in repressors', sensitizers', or middle group's preferences for threatening television programs or physical activities, and thus the hypotheses were rejected. Non-significant tendencies in the data, in hypothesized directions, suggest further research.

A procedure in which the S- was prevented from being responded to, by electro-magnets, was used to establish color discriminations. The procedure was modified in Situation 1, to include the prevention of responses to the S+ if the S- was responded to first. The original procedure and modified procedure were used in Situation 1, with only the modified procedure being used in Situations 2 and 3. The procedure of reinforcing responses to the S+ and extinguishing responses to the S-, through nonreinforcement, was used in Situation 4. Data recorded consisted of the number of trials, the number of reinforcements, and which stimulus was first responded to. Criteria for the acquisition of a discrimination was 100 first responses to the S+. Results indicated that the modified procedure was much more effective in establishing the discriminations, than the original procedure or the procedure of reinforcing responses to the S+ and extinguishing responses to the S-. The modified procedure enhanced the establishment of stimulus control, reduced the number of errors and eliminated stereotyped responses.

Rates of primary production and community metabolism were monitored over a one year period using the diurnal oxygen method. Certain physico-chemical parameters were also measured, and autotrophic standing crops were estimated. An in-depth study was made of the phytoplankton community and various diversity indicies were calculated. Simple correlations were run between all parameters measured (biotic and abiotic), and their inter-relationships examined. Multiple linear regression analyses were used to develop equations predictive of production and community metabolism. Bluegreen algae were the dominant phytoplankters with blooms occurring in late summer and fall. Yearly mean production was approximately 21 kcal per meter square per day with a mean photosynthetic efficiency of 1.2 per cent. Of the various parameters measured turbidity and water temperature were most important in determining rates of primary production.

This study is concerned with drug knowledge and drug abuse attitudes of a sample of pre-adolescent schoolchildren, 90 from an urban community and 204 from two rural communities. The seven hypotheses tested compared drug knowledge levels and drug abuse attitudes with the variables of community of residence, sources of information, racial identity, acquaintance with drug users, and church affiliation. High levels of drug knowledge were found to be related to rural residence, perceived parental disapproval of drug use, frequency of church attendance, and, to a minor degree, to acquaintance with peer group drug users. The sample held negative views of drug abuse and intolerant drug attitudes correlated significantly with rural residence, parental interest in talking about drugs, church affiliation, and frequency of church attendance. High drug knowledge levels and intolerant drug abuse attitudes were related to only the .20 level of significance.

William Blake's prophetic works are made up almost entirely of a unique combination of symbols and imagery. To understand his books it is necessary to be aware that he used his prophetic symbols because he found them apt to what he was saying, and that he changed their meanings as the reasons for their aptness changed. An awareness of this manipulation of symbols will lead to a more perceptive understanding of Blake's work. This paper is concerned with three specific uses of serpent imagery by Blake. The first chapter deals with the serpent of selfhood. Blake uses the wingless Uraeon to depict man destroying himself through his own constrictive analytic reasonings unenlightened with divine vision. Man had once possessed this divine vision, but as formal religions and a priestly class began to be formed, he lost it and worshipped only reason and cruelty. Blake also uses the image of the serpent crown to characterize priests or anyone in a position of authority. He usually mocks both religious and temporal rulers and identifies them as oppressors rather than leaders of the people. In addition to the Uraeon and the serpent crown, Blake also uses the narrow constricted body of the serpent …

This work presented the question: to what extent did each period and its events have on the development of the various schools of thought concerning Niccolo Machiavelli. The age of Reformation in its quest for theological purity gave birth to the myth of the evil Machiavelli. The Enlightenment, a period which sought reason and science, founded the myth of the scientific Machiavelli. The eruption of nationalism in the nineteenth century created Machiavelli, the patriot, and this was quickly followed in the twentieth century, an age of unrest, by the rebirth of all previous interpretations. These schools of thought developed as much from the changing tide of events as from the scholarly research of the writers. One of the reasons for the diversity of the Machiavellian literature was that each writer sought his antecedents on the basis of myth rather than where it might realistically be found. Machiavelli and Machiavellianism were abused and misused because modern man did not know himself. He viewed his origin incorrectly and thus could rest on no one explanation for himself or -Machiavelli. Machiavellianism developed from a collection of myths, each started in an attempt to explain the unexplainable, man. Not Machiavelli's politics, but what man …

The purpose of this study was to investigate recruitment practices used .in industrial arts education programs and to identify factors which influence students in deciding to prepare for teaching industrial arts. Findings led to these conclusions: 1. Teacher-respondents were mostly unaware of or apathetic to the -problem of recruiting for the future. 2. Teachers used three types of recruitment practices: (a) presentations about industrial arts teacher education; (b) motion pictures and slides on industrial arts; and (3) articles in periodicals written about teaching and college activities.

This interpretative study attempts to ascertain why the Nazi movement gained the support of German voters by examining its persuasive strategies. The growth of the movement was divided into three periods. In each period, the verbal and non-verbal rhetorical strategies were explored. It was found that the movement's success stemmed largely from the display of party unity, the display of power through the Storm Troopers' use of violent street rhetoric, and the spread of Nazi ideals through speeches at meetings, on tours, and especially at the Nuremberg Party Rallies. Their communication capitalized skillfully on the conditions in Germany between 1919 and 1933. Hopefully, the findings of this study add to our knowledge of the role of rhetoric in creating mass movements.

By the early 1900s, ambitious business leaders were transforming Dallas, Texas into a rising commercial metropolis. However, the problems created by rapid urban growth spawned demands from all classes of citizens upon local government for more public improvements and services. When city government failed to meet these demands, many citizens began to seek a more responsive governmental system. Their search led to the establishment of a commission government which, like the modern business corporation, delegated authority to competent, well-paid administrators. Civic reformers hoped that the new system would represent overall community interests. However, Dallas business leaders, believing that continued urban expansion depended upon a city government attuned to business interests, organized a political movement which won them control of the city commission.

The study conducted consisted of an interview with forty-eight varsity baseball coaches of the University Interscholastic League high schools within the Dallas-Fort Worth metroplex. Overall the coaches were found to be a highly qualified group of physical educators. Findings of the study included data on the playing experience, coaching experience, and educational backgrounds of the coaches. Physical education/ coaching areas investigated included: 1) medical-legal, 2) sociological and psychological, 3) kinesiological, 4) physiological, and 5) theory and techniques of coaching. Recommendations included continued professional involvement of coaches, further studies on professional preparation, a course in legal liability, and implementation of a "coaching endorsement".
