This study examines the consequences of interdependence between Saudi Arabia and the United States from 1960 to 1978 as it relates to the concepts of cooperation and conflict. Research on interdependence focuses primarily on relations among Western countries and on whether interdependence is increasing or decreasing between them. It has rarely addressed relations between countries with different levels of economic development or the consequence of interdependence for international relations in terms of conflict and cooperation. Specifically, this study examines the following question: Does the level of interdependence between Saudi Arabia and the United States have any affect on the level of bilateral conflict and cooperation between the two countries? The hypotheses are tested using regression analysis. The primary conclusion is that increases in bilateral interdependence between Saudi Arabia and the United States from 1960 to 1978 produced increased cooperation as well as conflict.

Five chemicals indigenous to the dental office environment that may cause toxic effects are formaldehyde, phenol, acrylic, mercury, and nitrous oxide. These chemicals create abnormal stress on physiological and psychological systems of the body resulting in symptomatology and pathology when the body defenses can no longer maintain homeostasis by adaptation. This study demonstrated serious behavioral consequences of chemical and heavy metal exposure. This study provided evidence that a significant percentage of dental office personnel who are exposed to the dental office chemicals show psycho neurological dysfunction. It was concluded that these individuals suffer adverse reactions to the chemicals in their work environment. The problem areas included perceptual motor difficulty in cognitive functioning, concern with bodily functions, despondency, and interpersonal problems.

This dissertation discusses the complicated relationship (known as the comitatus) of kings and followers as presented in the heroic poetry of the Anglo-Saxons. The anonymous poets of the age celebrated the ideals of their culture but consistently portrayed the real behavior of the characters within their works. Other studies have examined the ideals of the comitatus in general terms while referring to the poetry as a body of work, or they have discussed them in particular terms while referring to one or two poems in detail. This study is both broader and deeper in scope than are the earlier works. In a number of poems I have identified the heroic ideals and examined the poetic treatment of those ideals. In order to establish the necessary background, Chapter I reviews the historical sources, such as Tacitus, Bede, the Anglo-Saxon Chronicle, and the work of modern historians. Chapter II discusses such attributes of the king as wisdom, courage, and generosity. Chapter III examines the role of aristocratic women within the society. Chapter IV describes the proper behavior of followers, primarily their loyalty in return for treasures earlier bestowed. Chapter V discusses perversions and failures of the ideal. The dissertation concludes that, contrary …

Ten caucasian male quadriplegics were compared with eight sedentary caucasian male controls in regards to left ventricular dimensions and mass obtained from echocardiograrns. The interventricular septum (IVS), left ventricular posterior wall (LVPW) and left ventricular internal diameter (LVII) were within normal limits for both groups. However, the INS in the SCI were significantly thicker than controls (p <0.05). Myocardial thickness was larger in SCI subjects (p <0.05). Absolute left ventricular mass (LVM) and total left ventricular volume was not different ( p > 0.05), but SCI subjects had significantly greater LVM to lean body mass ratios. Echocardiographically, SCI patients demonstrate concentric hypertrophy. This suggests adaptive response to chronic increase in afterload pressure secondary to their daily activities and muscle spasticity.

In two separate experiments, weight adjusted doses of nocodazole and acrylamide were injected intraperitoneally at various time intervals into twelve week old female mice. Within the nocodazole experiment, the doses were injected at varying time intervals before and after mating. On day seventeen of gestation, the female mice were sacrificed and their uterine contents examined. Nocodazole induced a significant increase in reproductive pathology per total implants when administered one hour after mating to the (SECxC57BL)F, stock: 5.00% total deads, 70.23% moles, and 3.41% abnormal fetuses. Acrylamide treatment produced a significant reduction in live births when administered six hours after mating: 50.86% moles and 46.46% living fetuses per total implants.

The present research incorporated the content of basic statistics into the Artificial Intelligence Physics Tutor (ARPHY), which was used as the expert system shell, and investigated the effects of the Artificial Intelligent Statistics Tutor (ARSTAT) as a supplement to learning statistics at the college level. Two classes of an introductory educational statistics course in the Department of Educational Foundations, University of North Texas, were used in the study. The daytime class was used as the experimental group and the evening class was used as the control group. The experimental group's lecture/discussion was supplemented with ARSTAT, and the control group received only lecture/discussion. A one-way analysis of covariance was used to compare students' test scores. No significant difference was found; however, the adjusted mean score of the experimental group was slightly higher than that of the control group. A two-way analysis of covariance showed no significant main effect or interaction between gender and study technique. A second two-way analysis of covariance showed no significant interaction between the students' attitude toward statistics and the study technique used. However, the students with a statistics-positive attitude scored significantly higher on the test than students who had a negative attitude toward statistics. This study concluded …

Different family structures and levels of parental and financial stress were investigated in relation to children's overtly expressed fears, and secondarily, covertly measured fears and concerns. The family structures consisted of divorced and remarried families divided into those divorced less than two years and those divorced greater than two years. Intact families were used as the control group. One-hundred-twenty-one children from six to eleven years of age and their biological mothers from a semirural, southwestern town comprised the sample. The children were administered five instruments assessing overt fears, covert fears/concerns, and positiveness in family relationships. Mothers were given eight self-report measures which included a questionnaire, a report of their child's overt fears, and an indication of the positiveness in family relationships. Results indicated that the children of divorced, single mothers tended to report greater overt fears than remarried and intact families. Indications of covert fears of death and separation were also suggested. This was especially true for those single mothers divorced less than two years. Children of intact families did not generally differ from remarried groups although there were implications that remarriage too soon after divorce may impact covert fears as well as positive feelings toward the stepfather. Children of …

This study examines the relationships among student socioeconomic status, school district enrollment, minority enrollment, district expenditure per pupil, and the teaching experience of faculty as these variables influence the achievement scores of secondary students in Texas. Data from a total of 1,061 Texas school districts were used to determine the effects of the indicated district-level predictor variables on three criterion variables: reading, mathematics, and writing scores for the 11th-grade Texas Education Assessment of Minimum Skills (TEAMS). The study led to the following conclusions: 1. Low socioeconomic status of students in Texas, as in the rest of the United States, insures that test scores will be lower if all other variables are held constant. 2. Large minority populations are strong predictors of low test scores, especially in mathematics and reading. 3. Students in districts whose faculty had a high average of years of teaching experience also scored high in achievement tests, especially in mathematics and writing. 4. High average district expenditure per pupil predicts high test scores, especially in reading. 5. School district size or enrollment has low predictive value of test scores. Among several specific recommendations, this study advises that further study be done concerning the most effective ways to …

This research study examined the perceptions of school administrators and of historic site directors toward the function of the sites in the public school curriculum. In-depth, personal interviews were conducted, tape-recorded, and transcribed at six selected sites, representing the various ethnic historic settlements of Texas, a variety of population densities, each of the major physical geographic regions, and different economic levels in the state. Data analysis involved careful study of the taped interviews, comparisons of responses given by people of similar roles, and comparisons of responses regarding the same site. Documentation of elements of the historic sites, of programs offered, of participation of the local school district in programs, and of written school policies were examined. The perceptions of the interviewees along with recommendations for changes were noted. Responses varied from expressed impression of students who are steeped in local history and are bored with their heritage, to enthusiastic positive opinions that the prosperity of the community is directly related to the strong identification of the citizens with its local history. The role of local history and of specific sites in the curriculum of the public schools is not consistent in Texas. This research study suggests that positive gains are …

This work includes two unrelated areas of research. The first portion of this work involved combusting densified refuse derived fuel (dRDF) with coal and studying the effect that Ca(0H)2 binder had on reducing polycyclic aromatic hydrocarbon (PAH) and polychlorinated biphenyl (PCB) emissions. The second area of work was directed at developing nondestructive infrared techniques in order to aid in the analysis of postage stamp adhesives. With Americans generating 150-200 million tons a year of Municipal Solid Waste (MSW) and disposing of nearly ninety percent of it in landfills, it is easy to understand why American landfills are approaching capacity. One alternative to landfilling is to process the MSW into RDF. There are technical and environmental problems associated with RDF. This work provides some answers concerning the amount of PAH and PCB emissions generated via the combustion of RDF with coal. It was found that the Ca(OH)2 binder greatly reduced both the PAH and the PCB emissions. In fact, PAH emissions at the ten-percent level were reduced more by using the binder than by the pollution control equipment. If the Ca(0H)2 binder can reduce not only PAH and PCB emissions, but also other noxious emissions, such as acid gases or dioxin, …

In this study, a computerized marriage enrichment program that gave couples instruction on communication skills and problem-solving was developed and tested. Couples completed the marriage enrichment courseware together on a computer. Forty couples from a metropolitan area in North Texas volunteered to complete the marriage enrichment courseware. Ten couples were randomly assigned to each of the following four groups: an experimental group that received the pretest followed by treatment and a post-test, a control-wait group that completed pre- and post-tests, an experimental group that received treatment followed by a post-test, and a post-test only control-wait: group. Three hypotheses were generated predicting that experimental subjects would significantly increase their marital communication skills following the treatment and that wives in the pre-test and experimental groups would achieve higher marital communication scores than would husbands. The dependent variable was the score on the Marital Communication Inventory (Bienvenu, 1970). Analyses of variance did not reveal any differences between husbands, wives, and couples at the pre- or post-tests. A three way analysis of variance revealed a significant main effect for treatment (p < .04), but no interaction effects were found. In related findings, a t-test on the post-test minus pre-test difference for wife's scores was …

The University of Piano was a private, liberal arts college with a campus in Piano, Texas and an extended campus in Frisco, Texas. The University was incorporated in 1964 under the original name of the University of Lebanon. Classes began in temporary space in downtown Dallas in 1964 and continued on its campuses in Piano and Frisco until the summer of 1976. The University of Piano was comprised of two separate schools within the University: the School of Developmental Education and the Frisco College of Arts and Sciences. This study explores the curricula of both schools and the students and faculty who participated in both programs. This study focuses on the establishment, development and final closing of a wholly privately supported university which accepted both traditional college students and students whose basic academic skills or neurological development prevented their acceptance into traditional college programs. It addresses the history of the University, the roles of its leaders, and the lasting effects of its programs.

This study had two objectives: to achieve suspension cultivation of Sf1Ep cells and to develop procedures for achieving the replication of T. pallidum in those cell cultures. Sf1Ep cells have been the sole cell line used for the in vitro cultivation of T. pallidum. A study was undertaken to determine if other cell lines can support growth of T. pallidum. Rabbit skin fibroblasts (RAB-9), nude mouse ear (NME) cells, and normal rebbit testis fibroblasts (RT) were compared to Sf1Ep cells for their ability to support in vitro multiplication of T. pallidum. RAB-9 cells supported multiplication of treponemes equal to that of Sf1Ep cells. NME and RT cells also supported growth but to a lesser extent than Sf1Ep cells. Utilization of alternative cell lines may lead to improved in vitro growth of T. pallidum including possible serial passage.

This research is part of an effort to develop non-mammalian surrogate immunoessays with the earth worm Lumbricus terrestris to assess immunotoxic potential of xenobiotics to mammals. The objective was to determine if earthworm immunoessays, namely E- and S- rosette formation and phagocytosis, are sensitive to a known mammalian immunotoxin, the PCB Arclor 1254. Results are presented in terms of PCB exposure and tissue concentrations during uptake/depuration.

The use of arguments containing increasingly technical materials has grown significantly in the recent years. Specifically, arguments that are used to justify military expenditures or to allege violations of international agreements are becoming more sophisticated. This study examines the dissemination and use of technical argument in claims made by the United States government that the Soviet Union violated chemical and biological treaties in Southeast Asia and Afghanistan. This study employs the Jowett-O'Donnell method for analyzing propaganda to determine the extent and effectiveness of the government's claims. The study concludes that propaganda was used extensively by the government in order to justify new weapons programs and that the propaganda campaign was effective because of the technological orientation of its claims.

This document identifies elements of a stylistic change which occurred in several of the pieces Rachmaninoff wrote during the last years of his life. These elements reflect a progressive trend in his music, which certainly maintained in spite of the change, its characteristic sound. The Variations on a Theme of Corelli, Op. 42 illustrate these new developments in their lean, angular unison sonorities, stripped of chordal padding and virtuosic display, in their percussive, staccato and incisive ostinato rhythmic figures, astringent chromatic harmony and modern air of detachment. The Rhapsody on a Theme of Paganini, Op. 43 confirms this stylistic development in its remarkable similarity to the Corelli Variations. In the last twenty-six years of his life in exile from his homeland, making his way around the world as a concert pianist, Rachmaninoff wrote only six major works. Perhaps his increasing age, separation from homeland, and the musical revolutions surrounding him in the Western world produced this stylistic development.

Two-dimensional electrophoretic protein profiles of in vivo and in vitro propagated T.pallidum subsps. pallidum Nichols strain were analyzed and compared. This comparative analysis revealed two in vitro synthesized, cytoplasmic cylinder-associated polypeptides with molecular masses 29.5 and 34.7 kDa, pI 5.62, and one in vitro "lost" polypeptide with molecular mass 34.7 kDa, pI 5.34. integral membrane proteins of in vitro and in vivo propagated T. pallidum was identified by phase partitioning with the nonionic Triton X-114, and twelve outer membrane-associated, antigenic proteins were identified in western blots probed with pooled human secondary syphilitic sera. The solubilization of the outer membrane of T. pallidum with Triton X-114 were monitored by electron microscopy. Treatment of freshly harvested 35S labeled T. pallidum with 1% Triton X-114 resulted in solubilization of the outer membrane and reduction of the diameter of the treponemes from .14 +/- .02 micrometers to .095 +/- .003 micrometers. Examination of thin sections of untreated organisms showed integrity of outer and cytoplasmic membranes. In contrast, thin sections of Triton X-114-treated trponemes showed integrity of the cytoplasmic membrane but the loss of the outer membrane. The cytoplasmic cylinders generated by detergent treatment retained their periplasmic flagella, as judged by electron microscopy and immunoblotting. …

The purpose of this study was to describe factors affecting the use of instructional ideas by secondary teachers in the academic year following a series of staff development sessions designed to present information on effective teaching practices. The research questions addressed the characteristics of information selected for use in classroom practice and the characteristics and relative degree of influence of salient factors affecting the use of ideas. Ten teachers from a large suburban school district in North Texas were selected for this study. Qualitative techniques were used to collect data. Each teacher was interviewed three times and observed in the classroom setting. Documents such as lesson plans were analyzed as a third source of data. Several factors evolved from the data. In varying degrees, these factors predicted teacher use of new instructional practices. Some factors dealt with the teacher's level of understanding and internalization of the information. These factors were labeled as instrumentality, congruence, and analytical thinking. Two other factors which were fairly strong predictors were labeled cost and intrinsic motivation. Cost concerned the amount of time or effort required to implement new ideas versus the perceived benefit to either teacher or student. Intrinsic motivation concerned the personal desire a …

This study presents a topical and chronological analysis of the published works of Fritz Perls with particular attention to specified theoretical continua. The theoretical continua specified are: 1. Determinism vs. Free Will, 2. Unconscious vs. Conscious, 3. Monism vs. Dualism, A. Physical vs. Mental, 5. Nativism vs. Environmental ism, 6. Elementalism vs. Holism, 7. Reactive vs. Proactive, 8. Subjective vs. Objective, 9. Responsibility vs. Helplessness, 10. Thinking vs. Feeling, and 11. Heterostasis vs. Homeostasis. Each continuum is analyzed in reference to Perls' published thought and his stated beliefs are described and reported. Large sections of the dissertation are devoted to the intellectual, philosophical, and emotional influences that led Perls to write the theory of Gestalt therapy. The dissertation concludes with the report of Perls' position on each defined continuum, with discussion of empirical studies, Gestalt therapy and other major theories of counseling that hold parallel theoretical positions, concluding with a discussion of the limitations of the theory of Gestalt therapy and of this dissertation.

The purpose of this study was to investigate job satisfaction among physical education instructors at Teachers Colleges in Thailand by using the Faculty Job Satisfaction/Dissatisfaction Scale developed by Olin R. Wood, which was translated into the Thai language by Vatthaisong. The investigation was based on the 10 facets of job satisfaction selected from Herzberg's Motivation-Hygiene theory: achievement, growth, interpersonal relations, policy and administration, recognition, responsibility, salary, supervision, the work itself, and working conditions. The questionnaire consisted of 68 items. A 6-point rating scale was used for the 10 facets of job satisfaction. A total of 169 physical education instructors from 36 Teachers Colleges in Thailand, or 86.22% of the population, participated in this study. For this investigation, frequencies, percentages, one-way ANOVA, and the Scheffe method were used for data analysis. Significance was established at the .05 level. From the findings of this study it could be concluded that physical education instructors were satisfied with their jobs. The major sources of satisfaction were ranked as follows: interpersonal relations, the work itself, achievement, recognition, responsibility, working conditions, growth, policy and administration, supervision, and salary. The gender variable did not contribute significantly to job satisfaction, while region, age, level of education, work position, …
