A Stress-Inoculation Treatment Procedure for Test Anxiety in Elderly Students
The major purpose of this study was to evaluate the efficacy of a stress-inoculation treatment and an equally credible attention-placebo control in alleviating self-reported test anxiety and in facilitating intellectual performance in nontraditional (aged 50 and over) college students. Many studies have demonstrated the efficacy of cognitive-behavioral approaches in the treatment of test anxiety among young college students. The literature suggests that persons returning to school after a long absence who have subsequently enrolled as college students experience greater test anxiety and decrements in test performance in evaluative situations than their younger counterparts.

A Suite for Double Bass Transcribed From Pièces à une et à deux Violes, by Marin Marais: A Lecture Recital, Together with Three Recitals of Selected Works of J.S. Bach, Karl Ditters von Dittersdorf, W.A. Mozart, and Others
The music of Marin Marais, a major figure among the French Baroque bass viol composer-performers, is seldom played today. His compositions which are artistically and historically significant, should be available to instrumentalists of this century. Marais published five volumes of bass viol compositions. Seven movements were transcribed from the Second Suite of Marais' first volume. The first chapter is an introduction to Marais; the second chapter pertains to the bass viol and its styles of performance, and the final chapter illustrates the editing required for the transcription. The problems encountered were those of adapting the melodic, harmonic, and contrapuntal styles of the seven-stringed bass viol to the double bass which is normally monophonous. Melodic elements were unchanged, chords were simplified, and contrapuntal lines were retained by giving the second voice to the continuo bass.

Synthesis and Reactions of Some N-Nitrosamines
Nucleophiles react with the α-acetoxy derivative of α-hydroxybenzylbenzylnitrosamine at the carbonyl carbon of the acetoxy moiety followed by fragmentation to the very same intermediates formed by oxidative metabolism. Since α-acetoxybenzylbenzylnitrosamine has been shown to be able to acylate nucleophiles and since the nucleic acids are nucleophiles, then it is possible that this compound may cause mutations by an acylation pathway instead of or in addition to the more common alkylation pathway. The data in Part I of this dissertation should be considered in any further biological investigations of N,N-dialkylnitrosamine induced mutagenesis or carcinogenesis. The study of the synthesis, reactions, mutagenicity, and the possible correlation to compound liposolubility of cyclic N-nitrosamines was also investigated.

Theoretical and Experimental Linewidth Parameters in the Rotational Spectrum of Nitrogen Dioxide
Contributions to the second order collision efficiency function S ⁽²⁾ (b), used in semiclassical perturbation approaches to pressure broadening of microwave and infrared spectra, due to several leading terms, dipole and quadrupole components, in the expansion of the intermolecular interaction energy are derived by method of irreducible spherical tensor operators for molecules of arbitrary symmetry. Results are given explicitly in terms of dipole and quadrupole line strengths. General expressions for dipole moment line strength in the asymmetric rotor basis as well as quadrupole moment line strength for the special case of molecules with two independent quadrupole moment components are derived. Computer programs for calculating linewidth parameters in the rotational spectrum of ¹⁴NO₂ based on Anderson and Murphy and Boggs theories are presented.

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."

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.

Validation and Investigation of the Four Aspects of Cycle Regression: A New Algorithm for Extracting Cycles
The cycle regression analysis algorithm is the most recent addition to a group of techniques developed to detect "hidden periodicities." This dissertation investigates four major aspects of the algorithm. The objectives of this research are 1. To develop an objective method of obtaining an initial estimate of the cycle period? the present procedure of obtaining this estimate involves considerable subjective judgment; 2. To validate the algorithm's success in extracting cycles from multi-cylical data; 3. To determine if a consistent relationship exists among the smallest amplitude, the error standard deviation, and the number of replications of a cycle contained in the data; 4. To investigate the behavior of the algorithm in the predictions of major drops.

The Wind Was There
The Wind Was There is a setting for soprano voice and orchestra of two poems by Bravig Imbs (1904-46). Imbs was an American writer active in France for most of his career. He was also a violinist and amateur composer. The piece is in two movements, with a total duration of approximately twenty-five minutes. Each movement represents a different stylistic approach to the musical material. Movement one represents the spirit, though not the harmonic language, of the early twentieth century. The second movement shows the influence of Lutoslawski and Lugeti. This eclectic approach was chosen due to the quite different moods imparted to me by the two poems.The relationship between the soprano and the orchestra is not one between soloist and accompaniment, but is more in the nature of a symphonic dialogue.

Multiple-Quantum NMR in Solids
Time domain multiple-quantum (MQ) nuclear magnetic resonance (NMR) spectroscopy is a powerful tool for spectral simplification and for providing new information on molecular dynamics. In this thesis, applications of MQ NMR are presented and show distinctly the advantages of this method over the conventional single-quantum NMR. Chapter 1 introduces the spin Hamiltonians, the density matrix formalism and some basic concepts of MQ NMR spectroscopy. In chapter 2, {sup 14}N double-quantum coherence is observed with high sensitivity in isotropic solution, using only the magnetization of bound protons. Spin echoes are used to obtain the homogeneous double-quantum spectrum and to suppress a large H{sub 2}O solvent signal. Chapter 3 resolves the main difficulty in observing high MQ transitions in solids. Due to the profusion of spin transitions in a solid, individual lines are unresolved. Excitation and detection of high quantum transitions by normal schemes are thus difficult. To ensure that overlapping lines add constructively and thereby to enhance sensitivity, time-reversal pulse sequences are used to generate all lines in phase. Up to 22-quantum {sup 1}H absorption in solid adamantane is observed. A time dependence study shows an increase in spin correlations as the excitation time increased. In chapter 4, a statistical theory …

NMR Studies of Liquid Crystals and Molecules Dissolved in Liquid Crystal Solvents
This thesis describes several studies in which nuclear magnetic resonance (nmr) spectroscopy has been used to probe the structure, orientation and dynamics of liquid crystal mesogens and molecules dissolved in liquid crystalline phases. In addition, a modern high field nmr spectrometer is described which has been used to perform such nmr studies. Chapter 1 introduces the quantum mechanical formalisms used throughout this thesis and briefly reviews the fundamentals of nuclear spin physics and pulsed nmr spectroscopy. First the density operator is described and a specific form for the canonical ensemble is derived. Then Clebsch-Gordon coefficients, Wigner rotation matrices, and irreducible tensor operators are reviewed. An expression for the equilibrium (Curie) magnetization is obtained and the linear response of a spin system to a strong pulsed r.f. irradiation is described. Finally, the spin interaction Hamiltonians relevant to this work are reviewed together with their truncated forms. Chapter 2 is a deuterium magnetic resonance study of two 'nom' liquid crystals which possess several low temperature mesomorphic phases. Specifically, deuterium quadrupolar echo spectroscopy is used to determine the orientation of the liquid crystal molecules in smectic phases, the changes in molecular orientation and motion that occur at smectic-smectic phase transitions, and the order …

Time-domain multiple-quantum NMR
The development of time-domain multiple-quantum nuclear magnetic resonance is reviewed through mid 1982 and some prospects for future development are indicated. Particular attention is given to the problem of obtaining resolved, interpretable, many-quantum spectra for anisotropic magnetically isolated systems of coupled spins. New results are presented on a number of topics including the optimization of multiple-quantum-line intensities, analysis of noise in two-dimensional spectroscopy, and the use of order-selective excitation for cross polarization between nuclear-spin species.

Hydrogen and Deuterium NMR of Solids by Magic Angle Spinning
The nuclear magnetic resonance of solids has long been characterized by very large spectral broadening which arises from internuclear dipole-dipole coupling or the nuclear electric quadrupole interaction. These couplings can obscure the smaller chemical shift interaction and make that information unavailable. Two important and difficult cases are that of hydrogen and deuterium. For example, the homonuclear dipolar broadening, HD, for hydrogen is usually several tens of kilohertz. For deuterium, HD is relatively small; however, the quadrupole interaction causes a broadening which can be hundreds of kilohertz in polycrystalline or amorphous solids. The development of cross polarization, heteronuclear radiofrequency decoupling, and coherent averaging of nuclear spin interactions has provided measurement of chemical shift tensors in solids. Recently, double quantum NMR and double quantum decoupling have led to measurement of deuterium and proton chemical shift tensors, respectively. A general problem of these experiments is the overlapping of the tensor powder pattern spectra of magnetically distinct sites which cannot be resolved. In this work, high resolution NMR of hydrogen and deuterium in solids is demonstrated. For both nuclei, the resonances are narrowed to obtain liquid-like isotropic spectra by high frequency rotation of the sample about an axis inclined at the magic angle, {beta}{sub …

The Analysis of the Effects on Student Cognition of the Filmstrip Series, Introduction to Economics, Unit I, Microeconomics, When Used as a Supplement in a Principles of Microeconomics Class
Two teachers with two classes each participated in the research, which used a modified Campbell and Stanley equivalent time series design. Each class was randomly assigned four of eight filmstrips. Both experimental and control classes heard lectures on a module, the experimental group viewed the filmstrip, and both were posttested. Independent variables controlling for student differences, module difficulty, student attitudes, and the critical independent variable, viewing of the filmstrip (View), were regressed on student cognition. In the analysis, significant at the .001 level, View exerted a significant positive influence on cognition scores. No relation was discovered between student attitudes toward filmstrips and increased cognition.

Analysis of the Housing Status of the Elderly
Quality of housing was examined in relation to living arrangement, race, socioeconomic status, age, gender, income, health, and renter-owner status. There appeared to be differences in housing quality for those of younger ages, females, and owners. White subjects occupied good quality housing while Blacks occupied fair quality housing. Proportion of income allocated to housing was examined by renter-owner status, race, gender and living arrangement. Renters allocated an average of 34 per cent compared to 17 per cent for owners. Females living alone occupied good quality housing, committed the highest proportion of income to housing, and one-third had incomes below the poverty threshold while two-thirds were near poverty. Subjects allocated more for utilities than others over sixty-five, nationally.

An Analytical Survey of Educators' Attitudes Toward Competency Testing
This study addresses the attitudes of counselors, teachers, and administrators toward competency testing programs in their districts. ten districts from each of the four states --Arizona, California, Michigan, and Oregon-- were randomly selected to participate in the study. A total of 247 educators responded to the survey. The following conclusions were made on the basis of the findings: (1) The competency programs have the support the teachers, counselors, and administrators who work with them; (2) They are perceived as being effective in identifying students in need of remediation; (3) They are perceived as being most beneficial to the deficient student, but the setting of minimum standards had not lowered the expectations of the average and above average student; (4) They have not eliminated any programs or courses from the curriculum; (5) They have not limited the parameter of course content guides to concepts covered in the competency test; (6) They are perceived as nor being expensive to the district; (7) The competency program does add a burden of extra paperwork for the groups surveyed, especially the counselors; (8) Most competency programs involve teachers, counselors, and administrators in the planning; (9) Improvements in the quality of education and in student learning …

The Anthem in America: 1900-1950
During the first half of this century, a wealth of anthem literature was published and performed in the United States that, as a result of the deluge of new publications since those years, has been either forgotten or is unknown to modern church musicians. The purpose of this study is to make the best of this music known, for much of it is still both suitable and desirable for contemporary worship. The research is grouped into six chapters that are entitled: The Quartet Anthem, "Anthems in the Anglican Tradition," "Prominent Choral Ensembles and the Dissemination of the Anthem," "Anthems by Prominent Music Educators," "Anthems in the Russian Style," and "The Negro Spiritual."

Assessment Center Ratings as a Function of Personality Factors, Sex and Rating System
The purpose of this study was to examine the differences between the traditional global rating scale and a new behavioral rating scale in a university-based assessment center. It was hypothesized that personality factors, as measured by the 16PF and associated with the global ratings of performance would differ from those associated with the behavioral ratings of performance. It was further hypothesized that the associated personality factors would also differ for males and females. These hypotheses were ^confirmed. Pearson correlations were computed for ratings of males, females, and all subjects combined on both global and behavioral rating scales.

An Assessment of the Effect of News Announcements on Stock Prices of Oil and Gas Producing Companies
This empirical study is concerned with the extent to which news announcements affect the performance of common equity securities of oil and gas producing companies. The market effects of news announcements are considered to be of importance in resolving two issues. One concerns financial statement disclosure and the second concerns examination of prior oil and gas industry-related accounting research. This dissertation assumes capital market efficiency and addresses two research questions: do news announcements concerning activities of nonintegrated oil and gas producing companies affect the companies' common stock prices, and are announcements concerning nonintegrated oil and gas companies' financial, personnel, explorational, and developmental and operational activities used equally by investors in their decision-making?

The Attitudes of Edward Bok and the Ladies' Home Journal Toward Woman's Role in Society, 1889-1919
Edward William Bok, the Ladies' Home Journal's editor from 1889 to 1919, remained a confirmed proponent of Victorian womanhood. Yet, dramatic changes in American society made his perceptions increasingly anachronistic and, recognizing this, he reluctantly permitted his magazine's portrayal of woman to change with the times. The first part of the dissertation examines Edward Bok's Victorian attitudes toward woman's role in society. According to him, woman's intellectual, emotional, and physical inferiority and her moral and intuitional superiority harmonize perfectly to define a special sphere for her--the home—where she fulfills her roles as wife, mother, and homemaker. Outside the home, Bok permitted only a narrow range of activity for woman—church and club activities and even employment outside the home if finances required it. The second part of the dissertation illustrates how the Journal's image of woman changed during Bok's tenure, especially during the second decade of the twentieth century. At the outset, all departments of the Journal reinforced the editor's concept of woman, but by the time Edward Bok retired, in 1919. the magazine's image of woman contrasted sharply with Bo'k's personal views.

Carlos Seixas: The Development of the Keyboard Sonata in Eighteenth-Century Portugal. A Lecture Recital Together with Three Recitals of Selected Works of Johann Sebastian Bach, Samuel Barber, Ludwig van Beethoven, Fréderic Chopin, César Franck, Sergei Prokofieff, and Alexander Scriabin
This presentation demonstrates the significance both historically and aesthetically of the obscure Portuguese composer Carlos Seixas, (1704-1742), to the development of the keyboard sonata during the transitional period between the Baroque and Classic eras. The relationship between Seixas and his better-known colleague Domenico Scarlatti is explored and particular musical styles and techniques generally assumed as innovations of the latter composer are shown to exist in keyboard works of Seixas which probably pre-date those of Scarlatti. Thematically-related multi-movement sonatas and structural techniques anticipating the ternary single-movement sonata design are illustrated in several of Seixas1 sonatas. In addition to the recorded performance of selected sonatas by Seixas, this dissertation includes three tape recordings of selected piano works by J. S. Bach, Barber, Beethoven, Chopin, Franck, Prokofieff, and Scriabin.

Changes in Body Composition, Plasma Alanine, and Urinary Nitrogen in Rats Subjected to Negative Caloric Balance Through Diet, Diet/Exercise, and Exercise
Male Fischer rats (n=43) were used in a diet-diet/ exercise design to investigate the apparent protein sparing effects of exercise. The animals were divided into five groups: INITIAL (baseline), SEDENTARY (control), DIET, DIET/EXERCISE, and EXERCISE. Carcasses were analyzed for body composition, the blood for plasma alanine concentration and the urine for urea nitrogen concentration. The results showed no significant differences between groups in urinary urea nitrogen, plasma alanine, body weight, or carcass weights. The EXERCISE group had a significant increase in percent protein and a significant decrease in percent fat and grams of fat when compared to all other groups (p <.05).

The Chevalier de Saint-Georges: An Exponent of the Parisian Symphonie Concertant
The symphonie concertante, a product of the late eighteenth-century Parisian concert societies, provided a vehicle for display of the virtuoso style sought by contemporary audiences. The works of the Chevalier Joseph Boulogne de Saint-Georges, one of its chief exponents, served as strong influences on the development of the form and its diffusion throughout Europe. The symphonies concertantes of Opus VI, No. 1 and Opus X, No. 2 (according to thematic numbering of Barry S. Brook) date from ca. 1775 and 1779 respectively. A complete set of parts for each is to be found in the private collection of M. Andre Meyer in Paris (Opus VI) and in the Universitetsbiblioteket at Lund (Opus X). The thesis contains background material on contemporary Parisian musical society and the life of Saint- Georges, and a modern scoring of the above symphonies concertantes with analysis and conclusions.
