This paper provides a thematic approach to three major United States government document series relating to topics of early United States diplomatic relations with Mexico; treaty negotiations, the Santa 'Fe trade, the Texas question, and claims. The document series examined are .the United States presidential papers, United States Congressional documents , and the National Archives Record Group 59, diplomatic dispatches from United State Ministers to Mexico. Historians must make an evaluation of all: documentary evidence available for an accurate assessment of historical events. Inadequate analysis of these major United States document series has limited this necessary assessment in the area of United States Mexican diplomatic relations, 1821-1846.

This historical study examines the career of George I. Sanchez, New Mexican educator, who led many political and educational battles in New Mexico and Texas to improve educational opportunities for Spanish-speaking children. Archival materials from the State Records' Center of New Mexico, the papers of Senator Bronson M. Cutting, the Rockefeller Foundation Archives, the papers of President Lyndon Baines Johnson, Sanchez's private papers, unpublished materials at the University of Texas in Austin, oral history, and published materials were used in this study. The author used oral history and archival materials to gather much of the information for this work. The author extends special thanks and appreciation to Mrs. George I. Sanchez for making Sanchez's private papers available for study. The author also wishes to thank Dr. Hector Garcia, Senator Ralph Yarborough, Judge Carlos Cadena, Tom Sutherland, Arthur Campa, J. W. Edgar, Ed Idar, Jr., John Silber, and Connie Sprague, Sanchez's daughter, for their help.

This study examines the efforts of Radicals (Republicans) to establish a state-wide public school system in Texas between 1870 and 1873. Primary sources cover the chronological fringes of the period being examined. This study follows a chronological narrative with the four chapters examining first, educational trends in the southern states and Texas prior to Reconstruction, followed by examination of the Radical system in Texas, and, finally, its destruction by Conservative Texans. The final chapter focuses on immediate and long range results of Radical education. In examining the Radical educational program, an attempt has been made to dispel ideas popularly held by present-day Texans who believe that the Radical school program was simply another "carpetbagger" scheme for raiding the state treasury and building Radical patronage. This paper contends that the Radicals established as good a public school system as could be created at the time, and that it was administered in an honest and efficient manner. The system was destroyed by politicians and a grass roots revolt of taxpayers who had no faith in its methods, goals, or administrators.

This study investigated the incidence of peripheral hearing loss in sickle cell anemia and the possibility of central auditory nervous system involvement. Nine Black subjects with sickle cell disease and nine with normal hemoglobin were administered an auditory test battery. There appeared to be no correlation between number of crisis episodes, duration of symptoms, severity of symptoms, and audiologic manifestations. Acoustic reflex testing suggested the possibility of "aired neural function in the sickle cell group. Whether impaired function was due to peripheral VIIIth nerve or to central brain stem involvement could not be determined. Results of the central auditory test battery suggested the possibility of impaired or reduced central auditory function in subjects with sickle cell anemia.

This study analyzes the procedures and operations of the Quartermaster, Ordnance, Commissary, and Medical Departments during Scott's campaign to determine the efficiency of the prevailing logistical system. Unpublished and published government documents, official records, manuscript collections, memoirs, diaries, and newspapers provide the data. The first chapter describes the logistical departments interworkings; the remaining chapters detail the operations of the bureaus during the expedition's assembly and campaign against Mexico City. The evidence revealed organizational deficiencies which caused severe shortages, particularly in transportation, for Scott's army. The shortages severely hampered the expedition. Because of .the numerous victories over 'Mexican forces, however,. American leaders ignored the organizational deficiencies, These shortcomings reappeared to .impede operations during the Civil War.

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.

Although in 1915 there was no drama education in Methodist colleges and universities in Texas, today all Methodist schools of higher education in Texas have at least course offerings in drama. Southern Methodist University was one of the first Methodist schools to offer such courses which began with the hiring of Mary McCord to teach public speaking in September, 1915. The problem of this study is to explain the contributions of Mary McCord to the development of drama education at Southern Methodist University. It is recommended that the development of the department after Miss McCord retired be examined, that the students taught by Miss McCord who chose theatre as their life's work be interviewed about the effect of her training on their careers, and that a thorough study of the McCord Theatre Collection be undertaken.

The problem of this study is to determine the feasibility of using an operant treatment procedure to ameliorate several manifestations of depression. The purpose is to apply contingent positive reinforcement to the detection of nondepressive thoughts and to examine the effects of this procedure upon the frequency of nondepressive thoughts, idiosyncratic depressive manifestations, and scores on the Depression Inventory.

The problem of this study was the analysis of the pectoralis major during six antigravity exercises using electromyographc techniques. Thirty male subjects were used for the investigation from physical education classes at North Texas State University during the spring of 1976.

Research was conducted on twenty-seven preoperative myringotomy patients to clarify the correlation between tympanometry type and the presence of middle ear effusion. Test results indicate that the relationship between tympanometry and middle ear effusion is dependent on the amount of fluid present. In impacted ears primarily Type B tympanograms were obtained whereas for less than impacted ears all tympanogram types were seen. Also suggested was that a combination of height of the tympanogram and the amount of negative pressure may be diagnostically more important than negative pressure alone as an indicator of effusion. It was recommended that other measures in addition to tympanometry be employed in the diagnosis of middle ear effusion and that further research is needed to achieve optimal use of impedance audiometry.

This study focuses upon the Texas congressional delegation from 1933 to 1938 in an attempt to determine the extent of southern insurgency within that group. Following an examination of the Redeemer-insurgent dichotomy in southern politics since Reconstruction, the thesis analyzes roll-call votes on New Deal legislation concerning agricultural, financial, relief, and labor reform issues to demonstrate that a spirit of southern insurgency existed in Texas politics in the 1930's. The study concludes that Morris Sheppard, Sam Rayburn, Maury Maverick, W. D. McFarlane, R. Ewing Thomason, and Lyndon B. Johnson were politicians in the tradition of southern insurgents. The influence of these men, especially Sheppard, Rayburn, and Maverick, on the passage of legislation reflecting insurgent demands is demonstrated to be significant.

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.

This study has a twofold purpose: to demonstrate the causes of and various responses (British domestic, Iranian, Arabian, American, and Soviet) to the British decision to withdraw and to illustrate the regional political consequences of that withdrawal. The British Labour Government decision resulted primarily from an economic crisis. The various responses to the decision seem to have been motivated by national self-interest. Some of the Gulf states-- Iran, Iraq, Saudi Arabia, and Kuwait--predicted that the consequences of the withdrawal would be desirable while others--Bahrain, Qatar, and the United Arab Emirates-- predicted that the consequences would not be beneficial. In some ways, both sides were correct in their predictions.

The present study sought to alleviate the response cost inefficiency of the behavioral approach to controlling classroom hyperactivity by increasing the observer-student ratio via behavioral-electronic technology. A portable, integrated-circuit, counting and timing device was developed to enable immediate time-sequenced data recording and reinforcing of eight target behaviors by a single observer. A multiple-baseline design, across matched individuals was utilized to demonstrate the reinforcing effects. The results indicated a significant increase over mean baseline frequency in attention-to-task behavior for the group of eight students. It was concluded that by utilizing the behavioral-technological intervention strategy applied in this study, one observer could accurately monitor and reinforce eight students simultaneously and subsequently increase task attentiveness.

This study was conducted to investigate whether cognitive variables (as measured by six self-report inventories) covaried with changes in behavior following group assertiveness training as postulated by several assertiveness training theorists and practitioners. Statistical analysis of the data did not support any of the hypotheses. No significant differences were found between the groups on any of the self-report measures or the behavioral ratings, although experimental group subjects consistently scored higher (in the predicted direction) on all self-report measures or were rated higher than placebo group subjects. The hypotheses that experimental group subjects would exhibit significantly higher levels of self-reported assertiveness, self-acceptance, self-esteem, and self-confidence than placebo group subjects were rejected. The hypothesis that the experimental group would exhibit a significantly greater shift toward self-reported internal locus of control than the placebo group was rejected. The hypothesis that the experimental group would exhibit significantly larger decreases in levels of self-reported anxiety than the placebo group was also rejected. Furthermore, no support was found for the hypothesis that experimental group subjects would exhibit significantly higher levels of objectively-rated assertive behavior than placebo group subjects. An examination of the data revealed substantial improvements on each of the six self-report measures for subjects in …

This work is a study of the origins, development, and contributions of the black religious colleges of East Texas. The central purpose of the study is to reexamine the role Wiley, Bishop, Texas, and Jarvis colleges have played in black higher education. Although prior to 1960 most studies of Negro institutions of higher education described such schools as total failures in their effort to uplift American Negroes, since that time many scholars have published works which pointed up the achievements as well as the problems of those colleges. In addition to their efforts to provide the Negro community with capable leaders, the black religious colleges of East Texas also directed public service projects. Especially beneficial, these efforts, which included farm demonstration programs and home demonstration classes, were designed to help black people at whatever level needed. Wiley, Bishop, Texas College, and Jarvis have not been total failures. Although always academically weak, they have served the black community well. However, in spite of the valuable service they have rendered, unless these schools can generate new and larger sources of revenue, they stand little chance of remaining viable institutions. Each of these colleges desperately needs more money. Ironically, it may be that …

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.

Traditional personality research on accident behavior has produced conflicting opinions as to the traits that describe the "accident-prone" personality type. Other research has shown that psychosocial life stress, while partially determining the temporal onset of a variety of illnesses, may also be a factor contributing to increased accident liability. This study examined the role of temporary and stress-producing life changes in groups of accident-free and accident-involved industrial employees. The accident sample was found to have significantly higher stress over baseline during the period of accident involvement, but generally lower pre-accident levels than the non-accident sample. A cause-effect analysis of the data from within the accident-involved sample proved inconclusive. Several implications for future research and managerial actions to alleviate stress were also discussed.

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 problem with which this study was concerned was that of evaluating and comparing of locus of control scores and interpersonal distance among the institutionalized and non-institutionalized mildly retarded populations. The hypothetical assumptions specifically stated that the institutionalized retardates will be more externally oriented, will show a greater interpersonal distance towards stimuli with no specific expectancies. In view of the findings of the study, the following recommendations are offered: 1. Determination and evaluation of locus of control in retardates may be a useful technique in assessing their personality and understanding their psychological needs. Several investigators have been attempted with neurotics and subjects with character disorders, but none is reported with retarded populations. Such information may contribute to planning and programming for this particular group. 2. Determination of the retardates' interpersonal space may be an important approach in assessing their personality structure. Such studies have been conducted with the emotionally disturbed children, schizophrenics and normal subjects; however, none has been conducted with retardates. 3. The instruments used for this study have been designed for and standardized on samples of normal populations. To achieve more accurate results, these instruments should be designed for and standardized on a sample consisting of retarded subjects. …

The levels of total nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP), and their redox states were determined as the function of growth in S. cerevisiae. Cells growing in a medium containing 0.8% glucose exhibit two phases of exponential growth, utilizing glucose and ethanol, respectively. The NAD pool is 50% reduced during both stages of growth while the NADP pool is 67% reduced in glucose growth and 48% reduced in ethanol growth. The NAD/NADP ratio is constant during growth on glucose and a two-fold increase in the NAD/NADP ratio occurs upon exhaustion of glucose. The increased ratio is maintained during growth on ethanol. This alteration in the regulation of the relative levels of NAD and NADP may be due to a change in the regulation of NAD kinase and/or NADP phosphatase activities. These changes may be related to the redox state of the NADP pool.

The purpose of this study was to compare the effects of six- and twelve-second time intervals of eccentric strength training among college males. Thirty-eight students were used in two experimental groups and one control group. Subjects in the two experimental groups trained three days a week for seven consecutive weeks and were required to perform two sets -of eccentric exercise with three repetitions in each set for either six- or twelve-second intervals, depending upon the experimental group assignment. Results indicated that there was a significant differ ence between the experimental groups' mean strength gain and that of the control group. There was no significant difference between the two experimental groups.

This investigation, which was conducted on the post-secondary level and included vocational and academic students, was undertaken to develop an instrument to assess the attitude and knowledge of students concerning body language and to develop a module of instruction in body language to favorably influence their attitude and knowledge concerning body language. Hypotheses were formulated related to the differences in mean effective and cognitive scores of the experimental group who were taught body language and the control group. Additional hypotheses were formulated related to mean differences in the scores of students differing in age, sex, business experience, and prior exposure to body language. The findings of this study included first, the testing of the instrument; second, the testing of the validity of the research design and third, the testing of the hypotheses. The following conclusions are based on the findings of the study: the instrument seems to be acceptable for assessing the attitude and knowledge of post—secondary students concerning body language, the module of instruction in body language seems to be acceptable as a basis for influencing the attitude and knowledge of post—secondary students concerning body language, the mid-management and speech students were comparable in attitude and knowledge concerning body …

This investigation concerned teaching specific parent skills and improving parent attitudes. The purpose of this study was to compare the effectiveness of three techniques and combinations of techniques in teaching specific parent skills and improving parent attitudes. The techniques considered were microtraining, verbal reinforcement via immediate feedback, and traditional parent training.
