The Lieder of Beethoven: A Stylistic Analysis

Description: Beethoven is generally acknowledged to be the most important composer of the 19th century. However, many critics and musicologists dismiss Beethoven's Lieder as being of less musical value and sophistication than his more instrumentally conceived late vocal writings. The true musical sophistication of Beethoven's Lieder can be discovered by a careful study of the harmonic structure and the relationship between the vocal and the piano part in Beethoven's Lieder. In discussing Beethoven's Lieder style based on analysis, a number of aspects shall be examined: (1) the harmonic idiom and key relationships; (2) the role of the piano; and (3) other stylistic features.

Balance-of-Power Theory and the Ethiopian-Somali Conflict of 1977- 1978

Description: Balance-of-Power theory was tested by examining the 1977-1978 Ethiopian-Somali conflict and its outcome. The theory, according to Waltz (1979), claims to explain the international outcome arising from realpolitik or power politics, namely, the formation of balances of power. Given the close fit between the major developments leading to the eruption of conflict and the principal propositions of balance-of-power theory, the outcome of the conflict was expected to be consistent with that posited by the theory. This expectation was borne out by the study's finding which indicated that the conflict has produced a similar result. Confirmation of the theory was achieved by further subjecting the finding to the verification test established by Waltz.

Human Capital Investment in Taiwan

Description: This thesis attempts to analyze the relationship between economic growth and human capital investments in Taiwan. The study's general hypothesis is that increases in human capital investments will stimulate the growth of gross national product. The data were drawn from official Taiwanese publications from different sources. The first chapter emphasizes the importance of human capital investments. Chapter II reviews the related literature. Chapter III specifies the model and research methods. Chapter IV analyzes the impact of human capital investments on gross national product. The study is summarized and conclusions are drawn in Chapter V. Materials collected to analyze the above problem reveal that human capital investments have a positive and significant effect on economic growth. In fact, human capital investments and economic growth are mutually affected.

Relationship of Estrous Cycle to Herpes Simplex Virus Type 2 Susceptibility in Female Mice

Description: In CBA/NJ mice, splenic natural killer (NK) cell activity varies with stages of estrous. Susceptibility of ICR mice to intravaginal inoculation of herpes simplex virus type 2 (HSV-2) decreases with age. Susceptibility of female ICR and CBA/NJ mice to HSV-2 inoculated intravaginally and intraperitoneally was examined during the estrous cycle. In cycling ICR mice, greatest susceptibility to intravaginal inoculation was observed during diestrous and the least during metestrous. CBA/NJ mice were most susceptible to intravaginal inoculation of HSV-2 during diestrous. ICR mice were ovariectomized to mimic diestrous and found to be highly susceptible to intravaginal inoculation at all virus doses. No difference in susceptibility among phases of the estrous cycle was seen following intraperitoneal inoculation.

Perception of Timbral Differences Among Bass Tubas

Description: The present study explored whether musicians could (1) differentiate among the timbres of bass tubas of a single design, but constructed of different materials, (2) determine differences within certain ranges and articulations, and (3) possess different perceptual abilities depending on previous experience in low brass performance. Findings indicated that (1) tubas made to the same specifications and constructed of the same material differed as much as those of made to the same specifications, constructed of different materials; 2) significant differences in perceptibility which occurred among tubas were inconsistent across ranges and articulations, and differed due to phrase type and the specific tuba on which the phrase was played; 3) low brass players did not differ from other auditors in their perception of timbral differences.

The American Reception of Jane Austen's Novels from 1800 to 1900

Description: This thesis considers Jane Austen's reception in America from 1800 to 1900 and concludes that her novels were not generally recognized for the first half of the century. In that period, she and her family adversely affected her fame by seeking her obscurity. From mid century to the publication of J.E. Austen-Leigh's Memoir in 1870, appreciation of Austen grew, partly due to the decline of romanticism, and partly due to the focusing of critical theory for fiction, which caused her novels to be valued more highly. From 1870 to 1900 Austen's novels gained popularity. The critics were divided as to those who admired her art, and those who found her novels to be dull.

Back Pain Patients' Compliance with Vocational Rehabilitation: Use of the MMPI and HAT to Predict Outcome

Description: The use of the Minnesota Multiphasic Personality Inventory (MMPI) and the Health Attribution Test (HAT) for predicting referral compliance to a state vocational rehabilitation program was evaluated. Subjects included 53 patients (26 males, 27 females) who were chosen at random three to 18 months following discharge from an inpatient chronic and spinal pain center. Subjects were administered the MMPI and HAT upon hospital admission and seven outcome measures of referral compliance were obtained. A discriminant analysis was performed to test the hypothesis that certain items would best discriminate compliance. Most discriminative of compliance was the MMPI validity scale K (Wilks Lambda = .751, p ≤ .033). A regrouping of data into two groups, active and inactive, yielded ego strength (MMPI, ES) and ability to trust others (PA) as significant differentiating variables.

A Comparison of the Performance of the Radical and Conservative Models of Economic Development in the Carribean Basin

Description: The present study is an attempt to compare the performance of two competing models of economic development-- the conservative and radical models. The conservative model is represented by the Central American countries of El Salvador, Guatemala, and Honduras; the radical model is represented by Cuba. The following chapters focus on a comparison of these models as they have manifested themselves in the Carribean basin. The analysis of the performance of the models is conducted by comparing socioeconomic variables of the countries representing the models. The study looks at the time period 1960 - 1980 which coincides with the adoption of the two models in the respective countries.

"Fools for Christ": An Examination of the Ministerial Call in Three Novels by William Golding

Description: This thesis examines the ministerial call in three novels by William Golding, specifically The Spire, Darkness Visible, and Rites of Passage. The central character of each novel, a Christian minister, has a vision, or series of visions, which dominates his life. The call and vision(s) of Golding's ministers are examined in light of Jacques Ellul's The Humiliation of the Word, a work examining the differences between the word and the image. The ministerial call, in this thesis, is linked to Ellul's ideas about the word; the vision, in this thesis, is linked to Ellul's ideas of the image. As a result of following their vision(s) rather than their call, the ministers fail, and their lives end in despair and ruin.

Factors Affecting Perception of Fit of Jeans

Description: The purpose of this research was to determine if perception of fit in jeans will vary by target wearer, sex, educational background, political-social attitudes, and brand name. One hundred and sixteen usable questionnaires were completed by students enrolled in the 1987 spring semester at a university in North Texas. The questionnaire gathered data about perception of fit in jeans, social-political attitudes, clothing interest, and jeans consumption. No differences were found between perception of fit by sex or target wearer. Factors found to affect perception of fit were educational background, political-social attitudes, brand name, and clothing interest. Subjects indicated fit was the most important factor considered when purchasing jeans.

A New LC Column for the Separation and the Quantitation of Nucleotides

Description: A new column, Dionex AS4A, (polystyrenedivinylbenzene matrix) used for the separation of ribonucleotides and deoxyribonucleotides for the first time, and previously used for ion analysis was found superior to conventional silica columns because it separates ribonucleotides and deoxyribonucleotides. Resolution of dGTP was not possible with the Dionex column and CTP and GDP often co-eluted. Using conventional silica columns, monophosphates separated from diphosphates and diphosphates from triphosphates. Using the new Dionex column resolves all three simultaneously. The Dionex column resolved nucleotides with sharper peaks than silica columns, and the longer its retention time the better was the resolution. This Dionex column is stable, with 80 runs possible without cleaning while resolving ribonucleotides and deoxyribonucleotides to the picomole level.

Teratogenic and Mutagenic Potential of Triethylenemelamine, Ethyl Methanesulfonate, and N-Ethyl-N-Nitrosourea for Causing Fetal Anomalies in Mus Musculus

Description: In five separate experiments, weight-adjusted doses of TEM, EMS, and ENU were injected intraperitoneally into twelve week-old female mice six hours after mating. On day seventeen of gestation, the females were sacrificed and their uterine contents were examined. The effect of each agent was determined by its ability to cause malformations and death to the developing embryos. All treatment groups showed statistically significant elevated levels of malformations in comparison to their corresponding control groups. The reproductive damage induced in these experiments cannot be singularly attributed to teratogenesis or mutagenesis but a combination of the two.

Endogenous Nucleotide Pools in Growing Cells of Azotobacter Vinelandii

Description: The objective of this investigation was to examine the changes in the nucleotide pools of Azotobacter vinelandii during the growth cycle. Endogenous ribonucleotides were extracted from A. vinelandii using trichloroacetic acid (TCA; 12% w/v). The 5' mono-, di- and triphosphates of adenine, guanine, uracil and cytosine were separated and quantified by anion-exchange high performance liquid chromatography. Results indicated that the adenylate energy charge of A. vinelandii paralleled the growth rate during exponential phase and that it declined rapidly as the stationary phase was reached. In addition, the amount of each nucleotide in A. vinelandii tended to increase in the logarithmic phase and decrease in the stationary phase in a similar manner to the energy charge.

Relationship Between College Student Perceived Separation and Emotional Status

Description: This study explored whether depression was related to the way college students interact with their parents. A second purpose was to explore whether the emotional states of depression, anxiety, and hostility were associated with different types of adolescent dependence (Functional, Attitudinal, Conflictual, and Emotional) on each parent. A total of 108 undergraduate students from intact families completed self-report measures of depression, anxiety, hostility and psychological separation. A non-significant relationship was found between the way students relate to their parents and level of depression. However, subjects reporting angry or guilty feelings toward parents had significantly greater depression and hostility scores. Subjects reporting attitudes, values and beliefs that are not distinct from their parents also displayed significantly greater hostility scores. Furthermore, anxiety in the sample was significantly related to subjects' reports of dependence on approval, closeness and emotional support from parents.

Lord Acton and the Liberal Catholic Movement, 1858-1875

Description: John Dalberg Acton, a German-educated historian, rose to prominence in late Victorian England is an editor of The Rambler and a leader of the Liberal Catholic Movement. His struggle against Ultramontanism reached its climax at the Vatican Council, 1869-1870, which endorsed the dogma of Papal Infallibility and effectively ended the Liberal Catholic Movement. Acton's position on the Vatican Decrees remained equivocal until the Gladstone controversy of 1874 forced him to take a stand, but even his statement of submission failed to satisfy some Ultramontanists. This study, based largely on Acton's published letters and essays, concludes that obedience to Rome did not contradict his advocacy of freedom of conscience, which also placed limits on Papal Infallibility.

Stereotypes and Hiring Preferences Among Business Students as a Function of Psychologist's Attire

Description: To study what stereotypes exist regarding psychologists by the general public and determine whether and how this affects hiring preferences, 114 undergraduate business and non-business students at a large southwestern university were asked to participate. The Gough Adjective Check List was administered to determine what stereotypes are held by persons regarding psychologists. A study of visual perception/stereotype and hiring preference as a function of attire was also conducted. Three dress styles were used as stimuli. It was hypothesized that the groups would differ in their stereotypes of psychologists both cognitively and visually. There were no significant differences between the groups as a function of college major. However, a main effect for dress style was found. Possible explanations of findings are discussed.

A Parent Questionnaire Examining Learning Disabled and Non-Learning Disabled Children's Spatial Skills

Description: Investigations of children's spatial ability have typically looked at performance on laboratory tasks, and none have examined differences between learning disabled and non-learning disabled children. The present study surveyed sixty-seven parents of third and sixth grade children about the types of spatial activities children engage in everyday. Parents of learning disabled and non-learning disabled children were included. Results provided information about the types of spatial activities children engage in and the relationships between participation and performance. Major findings included differences between learning disabled and non-learning disabled children in navigational ability and in the strategies employed in difficult or ambiguous spatial situations. Findings were discussed in terms of the influence learning disabled children's negative self evaluations have on their performance.

Predicting the Site-Specific Bioavailability of Zinc Using the Indicator Species Procedure: A Case Study

Description: National Water Quality Criteria intended to protect aquatic life and their uses from the adverse effects of pollutants may not be appropriate due to site-specific factors that alter chemical bioavailability. The Indicator Species Procedure may be used to derive site-specific criteria in order to account for differences in site-specific bioavailability. This procedure was implemented using zinc for three chemically different site (river) waters. The purpose of this study was to quantify the bioavailability of zinc in each site water and correlate results to water quality parameters and/or zinc speciation. Results demonstrated that national criteria for zinc accurately predicted the experimentally derived site-specific values within a factor of two when adjusted for water hardness. Particulate forms of zinc were shown to be biologically unavailable under conditions tested.

Personality Enhancement and the Summer Camp Experience

Description: The study was undertaken to discover if the summer camp experience enhanced personality traits of participants in the camp program. The study was implemented at Greene Family Camp in Bruceville, Texas, during the summer of 1985. Utilized were analyses of variance and two types of factor analyses: principal-components analysis with varimax rotation and principal axis factoring with oblique rotation of factor matrices elicited. Five personality areas were analyzed--sociability, independence, achievement, environmental awareness, and spirituality. Spirituality emerged so strongly that it was removed from further analyses. Remaining personality areas emerged, but groupings of variables, especially those relating to achievement and independence, suggest an inherent commonality among the complex facets of personality. Based on these findings, the researcher recommends further investigation and careful replication.

Long-Term Effects of Quality Preschool for Disadvantaged Children

Description: The eleven studies which comprise the Consortium for Longitudinal Studies were described in order to determine long-term effects of preschool education on disadvantaged children. Research methods and results of the studies were evaluated and compared. An historical overview details the sociopolitical milieu from the time the eleven studies began in the 1960s to the present. Theories which impacted the preschool movement in the 1960s were also discussed, particularly those which concern the development of intelligence, the importance of early education and environmental impact on the development of intelligence. Demographic data were used to describe disadvantaged children's needs for quality early intervention programs. The results of the eleven Consortium studies indicate positive long-term effects for disadvantaged children enrolled in quality preschool programs.
