Mercenaries in Service to America: The "More Flags" Foreign Policy of the United States
On 23 April 1964, five months after assuming the office of President of the United States, Lyndon B. Johnson launched the "More Flags" program as United States policy. While the publicly stated purpose of.the "More Flags" program was to obtain as much non-military free world aid for the Republic of Vietnam as possible, the program's principle goal centered around Lyndon Johnson's desire to obtain an international consensus for America's policies toward Vietnam and Southeast Asia. The "More Flags" program continued to serve both goals for the remainder of Johnson's presidency. Although started with high expectations of success, the "More Flags" program never succeeded in achieving the levels of international cooperation Lyndon Johnson desired. In fact, the program's significant lack of success necessitated a number of changes, during the program's first year, in both its stated goals and in the methods used to prosecute it's implementation. The most important of these changes would be Washington's use of the program's beneficent objectives to mask it's use as the means through which the United States would purchase mercenary troops to fight in South Vietnam. "Mercenaries in Service to America: The 'More Flags' Foreign Policy of the United States," presents the available history of …

Negative Psychological States: Predictors for Immunological Health
Relationships of negative psychological conditions with general status of cell-mediated and humoral immune systems were investigated. A unique approach was utilized in that indexes representing multiple aspects of each branch of the immune system were employed to better indicate general immunological status. Differences in emotion-immune interactions between males and females were demonstrated. Results indicated a positive relationship between Trait Anger and Cell-Mediated Immunological Index. Particular criticisms of previous psychoneuroimmunological research were met by addressing sex differences and differences in various conditions of anger and depression, as well as through assessment of cumulative effects of negative emotions on immune system status. Directions for future research in eddressing similar issues are suggested. In general, results provide support for validity of mindbody interactionism and imply the need for revision of standard medical and psychological treatment.

Nonlinear Optical Properties of GaAs at 1.06 micron, picosecond Pulse Investigation and Applications
The author explores absorptive and refractive optical nonlinearities at 1.06 [mu]m in bulk, semi-insulating, undoped GaAs with a particular emphasis on the influence of the native deep-level defect known as EL2. Picosecond pump-probe experimental technique is used to study the speed, magnitude, and origin of the absorptive and refractive optical nonlinearities and to characterize the dynamics of the optical excitation of EL2 in three distinctly different undoped, semi-insulating GaAs samples. Intense optical excitation of these materials leads to the redistribution of charge among the EL2 states resulting in an absorptive nonlinearity due to different cross sections for electron and hole generation through this level. This absorptive nonlinearity is used in conjunction with the linear optical properties of the material and independent information regarding the EL2 concentration to extract the cross section ratio [sigma][sub p]/[sigma][sub e] [approx equal]0.8, where [sigma][sub p](e) is the absorption cross section for hole (electron) generation from EL2[sup +] (EL2[sup 0]). The picosecond pump-probe technique can be used to determine that EL2/EL2[sup +]density ratio in an arbitrary undoped, semi-insulating GaAs sample. The author describes the use of complementary picosecond pump-probe techniques that are designed to isolate and quantify cumulative and instantaneous absorptive and refractive nonlinear processes.

Correlates of Body Image in University Women
The relationship between maturation rate, body image, depression and eating disorder tendencies was explored in a group of 251 college-age females in order to better understand the developmental progression of body image and related variables. Two aspects of body image were measured, namely, level of body satisfaction and amount of body distortion. Body dissatisfaction was found to be associated with early maturation, depression, and eating disorder tendencies. Body distortion was not found to be associated with any of the primary variables. The significant relationship which was found between maturation rate and level of body satisfaction in young adult females suggests that pubertal timing may have lasting effects on the body satisfaction of women. Body satisfaction and depression were found to contribute significantly to the variance in eating disorder tendency.

Higher Education in the United Arab Emirates: University of United Arab Emirates and its Development
The purpose of this study was to trace the development of education, including higher education, in the United Arab Emirates. In order to complete this study, a computer search of available literature in the English and Arabic languages was constructed. The findings of this study revealed that although education at all levels has been expanded and improved, enrollment in vocational education and science remains low at the secondary level. Students also seem to avoid science and education at the college level. Based on the results of this study, further research should be conducted to determine the perceptions of alumni educational experience, community involvement in education, the role of national and multi-national cooperations in education, and women's education in relation to their participation in the labor force.

Job Satisfaction Among Business Administration Faculty in Selected Iranian Universities
This study investigated job satisfaction/ dissatisfaction among business administration faculty at selected public Iranian universities. It also examined the relationship between faculty job satisfaction/ dissatisfaction and selected demographic and professional activity variables. Finally, the extrinsic and intrinsic factors associated with faculty job satisfaction were analyzed. It was also concluded that, despite a positive correlation of the intrinsic and the extrinsic factors, Herzberg's two-factor theory is a useful model in a faculty job satisfaction research. Furthermore, Hill's FJS was found to be reliable and valid for use in faculty job satisfaction studies in the colleges and universities in Iran.

Influence of Item Response Theory and Type of Judge on a Standard Set Using the Iterative Angoff Standard Setting Method
The purpose of this investigation was to determine the influence of item response theory and different types of judges on a standard. The iterative Angoff standard setting method was employed by all judges to determine a cut-off score for a public school district-wide criterion-reformed test. The analysis of variance of the effect of judge type and standard setting method on the central tendency of the standard revealed the existence of an ordinal interaction between judge type and method. Without any knowledge of p-values, one judge group set an unrealistic standard. A significant disordinal interaction was found concerning the effect of judge type and standard setting method on the variance of the standard. A positive covariance was detected between judges' minimum pass level estimates and empirical item information. With both p-values and b-values, judge groups had mean minimum pass levels that were positively correlated (ranging from .77 to .86), regardless of the type of information given to the judges. No differences in correlations were detected between different judge types or different methods. The generalizability coefficients and phi indices for 12 judges included in any method or judge type were acceptable (ranging from .77 to .99). The generalizability coefficient and phi index …

Studies on the Mechanism of Protection by Carotenoids Against Photodynamic Killing in Curtobacterium Flaccumfaciens Pathover Poinsettiae
The mechanism of protection by carotenoids against photodynamic killing in Curtobacterium flaccumfaciens pathover poinsettiae (C. poinsettiae) was studied using pigment mutants isolated by treatment with nitrosoguanidine and DNA gyrase inhibitors. Growth rates, pigment composition, pigment levels and the ultrastructure of the wild-type streptomycin resistant strain of G. poinsettiae (wt-str) and all mutants were compared. One mutant, NTG-1, lacked colored carotenoids, and another, NTG-2, was a slow growing mutant containing low levels (14%) of wild-type carotenoid pigments. Except for NTG-1, the other pigment mutants had different proportions of the same pigments found in the wild type as determined by high performance liquid chromatography (HPLC). Only NTG-2 was morphologically distinct at the ultrastructural level.

Hospitality Education Programs in Senior Colleges and Universities in the United States
The purpose of this study was to describe senior-level hospitality programs and assess hospitality administrators' opinions concerning specialized accreditation during the 1990-91 academic year. Overall, administrators characterized the typical full-time faculty member as: being in a small program (1-3 members); being a non-ethnic minority; having a minimum four years industry work experience; having attained a doctoral degree; and holding the rank of associate professor. Part-time faculty members were described as: being in a small program (1-3 members); being a non-ethnic minority; having at leas one to three years industry work experience; having attained a master's degree; and holding the rank of instructor. Administrators characterized their programs as: located at public institutions; beginning after 1970; requiring graduates to acquire work experience; expecting increased enrollments; having placement services available; and not offering continuing education courses. Administrators indicated they were seeking accreditation or were accredited currently. They agreed slightly that accreditation would improve program image, help them meet their programs' missions and objectives, and provide assistance in planning.

The Musica Practica of Bartolomeo Ramos de Pareia: A Critical Translation and Commentary
This dissertation contains the first complete Latin-English translation of one of the most controversial music theory treatises of the fifteenth-century: the Musica Practica (Bologna, 1942) of Bartolomeo Ramos de Pareia. its title as well as its content illustrate the Renaissance transformation from the abstract mathematical approach of "musica speculativa" to that of an emphasis upon the everyday demands of the practicing musician. Although Ramos provides traditional explanations of the modes, counterpoint, "musica ficta," and white mensural notation, his innovations in temperament, solmization, mutation, and the gamut set this treatise apart from other ffifteenth-century music treatises. Ramos's rejection of traditional Pythagorean-Boethian-Guidonian explanations, coupled with his strong polemic criticisms of the auctoritas, resulted in a treatise that remained at the center of heated debate well into the sixteenth century.

The Nature of Reading Instruction in a Literature-based Reading Program
The purpose of this study was to describe the nature of reading instruction in a program using children's trade books instead of basal readers, and to identify patterns resulting in hypotheses regarding the nature of instruction. The study informs practitioners by providing descriptions of actual instruction, enabling readers to envision how reading instruction is accomplished using children's trade books, and it informs the research community by developing grounded theory concerning the nature of instruction in one literature-based reading program. The study can help bridge the polarization between traditionalists and whole language advocates through the descriptions of how traditionally accepted academic domains of reading instruction were accomplished. Also, it provides a model of a successful way to structure instructional time so that students spend more time actually reading, and it documents the social dimensions of instruction as important domain of reading instruction.

The Effects of Music and Music Vibration Using the MVT™ on the Relief of Rheumatoid Arthritis Pain
The pain relieving efficacy of music listening combined with vibrotactile cutaneous stimulation was determined. Music with mechanical vibration (30min. session; average amplitude of 26μm; frequency range of 60-600Hz.) was applied to subjects with rheumatoid arthritis using the Music Vibration Table (MVT). Scores from pain relief visual analogue scales (VAS) and McGill Pain Questionnaires (MPQ) were compared to groups with music alone and placebo. ANOVA and post hoc analysis indicated that VAS scores from music with vibration were significantly greater than music alone or placebo. MPQ scores also indicated larger percentages of change in pain perception for the music with vibration condition. However, subjects receiving music alone showed a large percentage of change on the affective dimension of the MPQ. This investigation supports the application of music with a controlled, measurable music vibration for the relief of pain. The results of this study warrant further evaluation and development of treatment protocols using music and music vibration.

Steepest Descent for Partial Differential Equations of Mixed Type
The method of steepest descent is used to solve partial differential equations of mixed type. In the main hypothesis for this paper, H, L, and S are Hilbert spaces, T: H -> L and B: H -> S are functions with locally Lipshitz Fréchet derivatives where T represents a differential equation and B represents a boundary condition. Define ∅(u) = 1/2 II T(u) II^2. Steepest descent is applied to the functional ∅. A new smoothing technique is developed and applied to Tricomi type equations (which are of mixed type). Finally, the graphical outputs on some test boundary conditions are presented in the table of illustrations.
