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 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 Unpublished and published government documents, official records, manuscript collections, memoirs, diaries, and newspapers provide the data.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.

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 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 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.

Time-compressed speech discrimination of children grouped as high and low risk on a reading-readiness test was examined. Children were grouped according to performance on a measure of reading-readiness skills. All passed a hearing screening at fifteen decibels for octave frequencies 250-4000 Hz. The Word Intelligibility by Picture Identification (WIPI) comprised the time-compressed speech task, in a sound field at seventy decibels Sound Pressure Level and zero degrees azimuth. The protocol for administration of the time-compressed speech task was sixty per cent time compression, then zero per cent time compression. Significant effects appeared for time compression ratio and test group. Average difference was twelve per cent and approximately eight per cent at zero.

The purpose of this paper is to compare a group of adolescents with the learning disorder of dyslexia and a group of adolescents without dyslexia in regard to their ability to make realistic drawings. Subjects selected for the study were from a suburban junior high school in which a random sample was taken of both dyslexic and non-dyslexic students. Each was given three standardized drawing tasks, including a still-life drawing, a contour drawing, and a perspective drawing. The drawings were judged by five evaluators on a continuum of realistic to non-realistic. The ratings were then analyzed by the application of the Mann-Whitney U-Test, which indicated that there are no significant differences in the abilities of the two groups to render drawings realistically.

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.

This study investigated the effects of environmental consequences and data 'collection in a behavior contracting procedure for obesity. Also, a validity study examined the GSR as a subject-independent-monitoring technique. Sixteen subjects matched on sex and percent overweight were assigned to one of three contract conditions or to a no-treatment condition. The Data Only Contract Group received consequences for data collection. The With Consequences Contract Group received consequences for data collection and behaviors relevant to weight loss. The Without Consequences Contract Group received no consequences for data collection or behaviors relevant to weight loss. The With Consequences Contract Group lost significantly more weight ( p ≤ .05) than the No Treatment Group. Specific effects were not determined. The results of the validity study suggest that the GSR may not be a valid instrument as a subject-independent-monitoring technique. Factors affecting the galvanic skin response's- effectiveness were discussed.

The purpose of the study have been: (1) to provide an explanatory, descriptive, and analytic viewpoint of the functions and structure of crisis intervention centers (2) to provide an intensive investigation of counseling and treatment practices in crisis intervention centers and (3) to relate the experiences that the writer has encountered as a resident counselor at Help House Inc. (twenty-four hour drug and crisis intervention center in Denton, Texas) to sociological, psychological, social psychological and philosophical constructs that deal with or pertain to crisis intervention, particularly in the area of drug use. The study indicates how participatory observation serves as an aid in acquiring insight into sociological areas such as crisis intervention centers. The role of the participatory observer is most important because concepts and theories arise out of actual situations.

Azotobacter and various fungi were grown together in nitrogen-free media. Maximal fungal growth in the medium used was possible only at the expense of Azotobacter cells and growth was always accompanied by acid production. When the medium reached a pH of 2, the bacterial cells were aggregated on fungal hyphae and the culture fluid appeared to be free of Azotobacter. Aspergillus niger grew well at the expense of viable bacteria and other fungi grew well on heat-killed cells of A. vinelandii. Members of the genus Hormodendrum, although not causing significant decrease in pH, were also able to clear turbid cultures of Azotobacter. However, clearing, which involved the attachment of bacteria to fungal hyphae, was dependent on acid production by the fungi. Bacterial aggregation was followed by hyphal attachment, bacterial inactivation, and finally, bacterial cell lysis.

This thesis investigates the political career of Stephen Dorsey, an Ohio industrialist who moved to Arkansas in 1871. Dorsey was elected to the U.S. Senate from Arkansas in 1873, served as secretary of the Republican National Committee for. the election of 1880, and was tried twice, in 1882 and 1883, for the Star Route postal frauds. Although Dorsey was acquitted, the Star Route frauds ended his political career. Separate chapters treat each phase of Dorsey's career. Major sources included the D41 Arkansas Gazette, the Congressional Record, the Garfield Papers, and the official transcripts of the Star Route trials. The thesis concludes that Dorsey's career was, the product of Ulysses S. Grant's influence within the Republican party in. the Gilded Age.

In this investigation, a content analysis was made with eleven lexicographical sources and three basal reading series to determine if art and art-related words were present. The analysis was made with the use of two charts, in which each was divided into eight categories of word context. The Composite Chart contained 6,576 words found in six lexicons, five word lists and forty-two readers, and the Reader Chart contained 407 words found only in the readers. The analysis revealed: dominant categories and percentages, word and cumulative word frequencies, high and low frequency words, and the percentage of words found in the basal readers as compared to the lexicographical sources.
