A Study of the Effects of a Systematic Program of Instruction in Helicopter Technology on Student Preferences for Kinds of Learning Experiences
The problem of this study was to compare two methods of instruction in helicopter pilot ground training in terms of cost of training and support services and customer satisfaction upon completion of training. The purpose of the study was the evaluation of a specialized program of instruction taught on videotape by comparison with conventional instruction. The significance of the study was related to savings in costs of instruction per trainee. Research questions for the study sought significant differences between mean scores achieved by students receiving the two treatments. Data providing information on specific characteristics of the learners were gathered as a preliminary step to establish similarity of the students in the two groups compared. A table of random numbers was used to select subjects from the population of student pilots entering training for the Bell model 206B helicopter during the months of March, April and May 1981. Upon completion of the course, all students were asked to complete an evaluation opinionaire relating to satisfaction with selected aspects of the instructional program.

The Use of Imagery for the Control of Experimentally Induced Pain: Prescribed Versus Individualized Imagery
Measures of pain tolerance and threshold were obtained for 100 male and female subjects in a pretest treatment posttest experiment using the cold pressor test. Subjects were divided into five treatment groups with an equal representation of males and females in each group. In addition each group was divided into high and low locus of control, resulting in a 2 X 5, locus of control-by—treatment, experimental design. Treatment groups received one of the following five sets of instructions: prescribed pleasant imagery, prescribed angry imagery, self-generated pleasant imagery, self-generated angry imagery, and expectancy control. Credibility checks were obtained on all groups, and an ANOVA revealed no significant differences in credibility ratings among the groups.

Operator Gauge Transformations in Nonrelativistic Quantum Electrodynamics
A system of nonrelativistic charged particles and radiation is canonically quantized in the Coulomb gauge and Maxwell's equations in quantum electrodynamics are derived. By requiring form invariance of the Schrodinger equation under a space and time dependent unitary transformation, operator gauge transformations on the quantized electromagnetic potentials and state vectors are introduced. These gauge transformed potentials have the same form as gauge transformations in non-Abelian gauge field theories. A gauge-invariant method for solving the time-dependent Schrodinger equation in quantum electrodynamics is given. Maxwell's equations are written in a form which holds in all gauges and which has formal similarity to the equations of motion of non-Abelian gauge fields. A gauge-invariant derivation of conservation of energy in quantum electrodynamics is given. An operator gauge transformation is made to the multipolar gauge in which the potentials are expressed in terms of the electromagnetic fields. The multipolar Hamiltonian is shown to be the minimally coupled Hamiltonian with the electromagnetic potentials in the multipolar gauge. The model of a charged harmonic oscillator in a single-mode electromagnetic field is considered as an example. The gauge-invariant procedure for solving the time-dependent Schrodinger equation is used to obtain the gauge-invariant probabilities that the oscillator is in an …

Conflict Management of the Organization of African Unity in Intra- African Conflicts, 1963-1980
The purpose of this dissertation is to examine and evaluate the role of the Organization of African Unity as an international organization in the solution of intra-African conflicts. For the purpose of this paper, eight conflicts from 1963 to 1980 were investigated. Utilizing these cases, the paper (a) examines four assumptions: (1) that regional actions promote settlements by isolating soluble local conflicts from more complex ones; (2) that intrastate conflicts are more difficult to resolve by regional organizations than interstate or border disputes; (3) that most of the boundary disputes in Africa are due to the arbitrary colonial boundary demarcations; and (4) that most of the causes of the ineffectiveness in its conflict resolution is as a result of poor administrative set-up, lack of resources, and failure of its commissions to operate effectively; (b) it answered the following questions: (1) Did the O.A.U. stop, help stop, or fail to stop the fighting; (2) Did the O.A.U. settle, help settle, or fail to settle the conflict; and (3) Was there super power intervention, and if so, to what effect? The methodology used is primarily case study method. Most attention is given to the way the O.A.U. handled the conflicts.

Photoconductivity Investigation of Two-Photon Magneto-Absorption, PACRH, and Deep Levels in n-InSb
A high resolution photoconductivity investigation of two 13 -3 photon magneto-absorption (TPMA) in n-InSb (n - 9 x 10 cm ) has been performed. This is the first time that two-photon absorption in a semiconductor has been studied with cw lasers only. With a stable cw CC>2 laser and a highly sensitive sampling and magnetic field modulation technique, a minimum of 4 2 transitions in the TPMA photoconductivity spectra can be observed. Most of these transitions are a result of the usual spherical approximation TPMA selections rules (An =0, ±2; As = 0 for e ⊥ B and Δn = 0; Δs = 0 for e || B) . However, some transitions, in particular several near the TPMA band edge, are not explained by these rules. The TPMA spectra have been found to depend upon crystallographic orientation. This has not been previously observed. The temperature variation of the fundamental energy gap Eg between 2 and 100° K is also obtained from TPMA experiments.

The Traité d'harmonie of Charles-Simon Catel
With the founding of the Paris Conservatory in 1795, a diversity of instructional methods for the teaching of harmony were used. Each theory instructor insisted upon using his own system; some relied heavily upon the theories of Rameau, while others used ideas based on eighteenth century German or Italian theorists. The Conservatory administration, realizing the need to unify theoretical instruction into a single method, formed a committee to evaluate the different harmonic systems available. After considering several treatises, including the theories of Rameau, the committee chose the Traité d'harmonie of Catel as the work best suited for their purposes. This investigation deals with Catel's synthesis of various theoretical principles, concentrating on his concise, often simplistic approach to harmonic theory. The major contribution of the Traité is the classification of chords into two categories: "natural harmony" and "artificial harmony." Catel believed that only one chord exists in harmony, the dominant ninth chord, which he derived from the first nine partials of the overtone series. From this chord, he formed the basic triads of "natural harmony," describing these chords as suspensions ("prolongations") of "natural harmony."

Gateaux Differentiable Points of Simple Type
Every continuous convex function defined on a separable Banach space is Gateaux differentiable on a dense G^ subset of the space E [Mazur]. Suppose we are given a sequence (xn) that Is dense in E. Can we always find a Gateaux differentiable point x such that x = z^=^anxn.for some sequence (an) with infinitely many non-zero terms so that Ση∞=1||anxn|| < co ? According to this paper, such points are called of "simple type," and shown to be dense in E. Mazur's theorem follows directly from the result and Rybakov's theorem (A countably additive vector measure F: E -* X on a cr-field is absolutely continuous with respect to |x*F] for some x* e Xs) can be shown without deep measure theoretic Involvement.

A Paradoxical Treatment Technique Versus a Behavioral Approach in Treatment of Procrastination of Studying
The present study investigated the relative efficacy of paradoxical, behavioral, and reflection-support treatments among college students who complained about procrastination of studying. Although there is much literature describing successful use of paradoxical treatment, there has been little substantive research. Paradoxical techniques offer more complex theoretical explanations than behavioral therapy even though in practice the procedure of each are often quite similar. Subjects were selected by their response to an ad in the school newspaper that offered free treatment for students who had problems with procrastination. Further screening of participants was done through clinical interviews. Thirty-three subjects were selected for treatment of procrastination with three clients randomly assigned to each of 11 advanced psychology graduate students who served as therapists. Each therapist provided all three types of treatment, one type of treatment to each of their three assigned clients.

An Evaluation of an Individualized Biology Program
The problem of this study was to compare the achievement and attitude of students in an individualized biology program, modeled after parts of the Proposed Texas Science Framework, with the achievement and attitude of students in conventional biology classes. The subjects used for the study were tenth grade, first year biology students in three high schools in a large North Central Texas city. Each of the three high schools was selected to represent a particular category of high schools. The categories were based upon the mean achievement scores for the students within a school. The categories of schools were above average, medium low, and very low. In each of the schools the classes and teachers in the experimental group and the control group were matched as closely as possible.

An Investigation of a Zen Meditation Procedure and Its Effect on Selected Personality and Psychotherapeutic Variables
The purpose of the investigation was to determine the effectiveness of Zen meditation practice in facilitating positive change on the personality variables time competence, inner direction, locus of control, and field independence, as well as to investigate the subjective experiences of novice meditators. Two population groups were included in the study: a student group and a clinical group. The student-population group consisted of forty-six undergraduate college students. The student subjects were randomly assigned to one of three groups: experimental group (Zen meditation group taught to focus attention on the breath, as well as a formal Zen posture), placebo group (formal Zen posture only), or control group (no treatment). The clinical-population group consisted of thirty-seven in-patient volunteers from the alcoholic-drug unit of a psychiatric state hospital. The clinical subjects were randomly assigned to either an experimental group (Zen meditation group which practiced focused attention on the breath, as well as a formal Zen meditation posture) or a control group (no treatment).

Chemically Active Odorants as Olfactory Probes
The initial step in odor recognition by the nose is the binding of odorant molecules to receptor sites embedded in the dendritic membranes of olfactory receptor cells. Despite considerable interest and experimentation into the nature of these receptor sites, little is known of their specificity to different types of odorant molecules. This lack of knowledge partially stems from the fact that the nature of receptor proteins is most effectively studied when specific and irreversible inhibitors are available for use as chemical probes, yet no such agents have been discovered for use in the olfactory system. A series of alkylating agents and other chemically active odorants were tested to determine whether they might react with specific odorant receptors and modify olfactory responses. Electroolfactogram (EOG) recordings were obtained before, during, and after treatment of the olfactory mucosae of grass frogs (Rana pipiens) with a chemically active odorant.

Retail Image Dimensions: An Empirical Analysis
The goals of this dissertation were to determine the salient cognitive dimensions of retail image in the perceptions of consumers and the image attributes related to those dimensions. This study took advantage of multidimensional scaling techniques (MDS) to create dimensioned perceptual maps based on nonpredetermined attributes. Similarities data about five Dallas shopping centers, gathered by questionnaires from a sample (n=181) of women shoppers interviewed at the centers, were analyzed to discover the perceived dimensions of image. Similarities data were also collected on fifteen attributes previously found to be significant. MDS configurations of the attributes were compared with the retail image configuration by means of a matrix fitting technique. These comparisons categorized the attributes according to the dimensions with which they were congruent. Evaluation of these groups provided a means for identifying and naming the primary perceptual dimensions. Saliency of the perceived dimensions was tested by congruency matching respondent preferences to perceptions.

An Investigation of the Management Accounting Framework for Performance Evaluation in American Multinational Enterprises
The development of adequate performance evaluation techniques for appraising foreign subsidiaries and their managers in an environment different from their domestic ones has been suggested as an area where management accounting should be extended. This study concerned the performance evaluation of foreign subsidiary managers with the following objectives: (1) to examine the relationships among environmental factors and foreign subsidiary performance, (2) to develop a multinational enterprise (MNE) environmental model to evaluate the performance of subsidiary managers on the basis of controllable factors only, and (3) to test the model in American multinational enterprises for the existence of association among environmental factors and measured performance of foreign subsidiaries. The research method employed in this study was to test for association between noncontrollable environmental factors of a particular foreign country and measured performance of the foreign subsidiary (in terms of ROI) in that particular country. Major noncontrollable factor groups used were economic, political-legal, educational, and social environmental constraints.
