Copper (II) Complexes with Deprotonated N-(2-hydroxyethyl)ethylenediamine

Description: This thesis reports the synthesis and characterization of two new copper(II) halide complexes with deprotonated N-(2-hydroxyethyl)ethylenediamine behaving as a bidentate. The magnetic properties of the new copper(II) complexes were studied from room temperature to liquid nitrogen temperatures. The magnetic data show that both complexes exhibit antiferromagnetic interactions with a singlet ground state and a thermally accessible triplet excited state. Magnetic data and infrared spectra indicate the complexes are halogenbridged. Deprotonation at an amine nitrogen is based on the presence of a hydroxyl stretching band in the infrared spectra. Electronic spectra and infrared spectra indicate the complexes are square planar. Elemental analyses, infrared spectra, electronic spectra, electron spin resonance spectra, and magnetic data are reported and discussed.

The Correlation Between Carbon-Proton and Proton-Proton Coupling Constants

Description: The correlation between the carbon-proton and proton-proton coupling constants have been studied in various 13 systems. Isocrotonic acid-carboxyl-3C, crotonic acid- 13 13 carboxyl-3C, and 5-norbornene-2-carboxylic acid-carboxyl-3C- 1,5,6,7,7-hexachloro were synthesized and their carbonproton coupling constants were analyzed. Nmr studies showed the magnitudes of the carbon-proton coupling constants to correlate well with analogous protonproton coupling constants, although the values of the couplings were larger than expected. The geminal olefinic couplings were considerably larger than all other couplings, but they were self-consistent. The signs of the carbon-proton coupling constants also were in agreement without exception with the signs of analogous proton-proton coupling constants.

The Crusade Against Lynching

Description: The problem with which this study is concerned is that of determining the methods and effectiveness of those persons and organizations attempting to stop the crime of racial lynching within the United States from the 1880's through the 1930's. Material for the study is compiled from a synthesis of secondary sources, congressional records, and newspaper accounts. The thesis is organized into five chapters dividing the crusade into five stages. These stages are; (1) establishing an institution, (2) the beginnings of discontent, (3) the crusaders unites, (4) co-operation from the North, (5) the South submits. The study concludes that the success of the crusaders is found in their ability to change the public sentiment from one supporting lynch law to one supporting anti-lynching spirit.

Denaturation, Renaturation and Other Structural Studies on Phosphoglucose Isomerases

Description: Structural properties of phosphoglucose isomerases isolated from a variety of species have been compared by peptide fingerprinting, predicted amino acid sequence homologies and by denaturation and renaturation studies. The enzymes are more readily denatured in guanidinium chloride than in urea, and the isomerase isolated from yeast is more stable toward acid pH than the rabbit muscle enzyme. The rates of guanidinium chloride-induced denaturation are markedly increased by ionic strength and decreased by substrates, competitive inhibitors or glycerol. The enzyme can be renatured, but only in the presence of glycerol. The renaturation process is dependent on protein concentration and temperature and provides a method for the formation of mixed species heterodimers.

A Descriptive Study of Value Systems Within the National Guard

Description: The purpose of this study was to determine the various values that may be contaminating the military's communication and to describe the predominant levels of psychological existence. The design of the study involved a National Guard battalion that was composed of 432 personnel. The sample drawn was 280. Data was collected through the use of a values test. Comparisons of the differing scores of demographic variables formed the bases of the conclusions drawn in the study. The results were highly significant at the .0001 level. The data indicate much support to the past research done in the field of Value System Analysis. Much research is yet needed to fully describe the value levels in all military organizations. This investigation is the beginning.

A Determination of Recreation Activities of Greatest Interest to Members of Senior Centers in Texas

Description: The purpose of this study was to determine what recreational activities were of greatest interest and appeal to members of nine senior centers in Texas and according to their age and sex. The nine senior centers were randomly selected from the forty-two centers in Texas. A minimum of twenty-five members at the selected centers were asked to respond to a questionnaire concerning their recreational activity interest. A total of two hundred seventy-four respondents completed the questionnaire, of which seventy-nine were males and one hundred ninety-five were females. The questionnaire consisted of nine recreational activity categories. These categories were designed to cover a wide range of recreational interest. Table games were the activities indicated by the respondents (88 per cent) to be of greatest interest. The activity that was indicated to be of least interest was dancing (47 per cent). Activities that included social contact had the greatest interest to the respondents. A recommendation was made that senior centers should stress those activities of a social group nature. The centers should also provide more outdoor life activities.

The Diagnostic Suitability of Goldberg's Rule for the Mini-Mult

Description: This study was undertaken to determine whether the Mini-Mult is able to function as well as the MMPI for a limited clinical purpose, the discrimination of psychosis and neurosis by Goldberg's rule. The smaller size of the Mini-Mult (71 items) allows conservation of time .and energy by subjects and professionals. Thirty male residents of the Austin State Hospital completed two standard MMPIs and one oral Mini-Mult. A fourth set of scores was obtained by extracting Mini-Mult from the first MMPI. Correlations and tests of significance were computed for raw scores and Goldberg's index scores. Results indicate no significant differences in the discrimination of psychosis and neurosis between the MMPI and the Mini-Mult.

The Effect on Group IQ Test Performance of Modification of Verbal Repertoires Related to Motivation, Anxiety, and Test-Wiseness

Description: To investigate the efficacy of a cognitive approach applied to problems of motivation, anxiety, and test-wiseness in a group test situation, programmed texts were used to Condition a repertoire of verbal responses relevant to each of these problems. Five sixth grade classes composed of 118 Students total were administered Otis-Lennon Mental Ability Tests in a pretest-posttest design. For the five groups, ANCOVA demonstrated a significant effect on raw scores, but not on IQ. Significant IQ and raw score gains were found for the combination group over the control group. Due to treatment lower IQ level students of the combination group made greater raw score gains than upper IQ level students.

Equivalent Sets and Cardinal Numbers

Description: The purpose of this thesis is to study the equivalence relation between sets A and B: A o B if and only if there exists a one to one function f from A onto B. In Chapter I, some of the fundamental properties of the equivalence relation are derived. Certain basic results on countable and uncountable sets are given. In Chapter II, a number of theorems on equivalent sets are proved and Dedekind's definitions of finite and infinite are compared with the ordinary concepts of finite and infinite. The Bernstein Theorem is studied and three different proofs of it are given. In Chapter III, the concept of cardinal number is introduced by means of two axioms of A. Tarski, and some fundamental theorems on cardinal arithmetic are proved.

Establishing a Special Interest City Magazine: D, the Magazine of Dallas

Description: The problem of this study was to determine how, and to what degree, a representative contemporary special interest magazine projected editorial, advertising, circulation, and financial obligations prior to publication and during its infancy. In essence, how did a representative nonsubsidized city magazine identify a marketable audience, resolve advertising and circulation policies, and meet financial obligations? Specifically, this study explored--in six chapters--the mechanics of pre- and post-publication planning at D, The Magazine of Dallas, which began publication in October, 1974. This study determined that twelve common denominators are essential, but are not necessarily a guarantee, for the success of a planned or newly introduced nonsubsidized special interest magazine.

Evolutionary Genetics of Three Semispecies of Wood Rats--Neotoma Albigula, Neotoma Micropus, and Neotoma Floridana

Description: Electrophoretic variation in 18 proteins encoded by 20 autosomal loci was used to compare the genetic relationships of 19 natural populations representing three species of the subgenus Neotoma. Of the 20 loci examined nine were monomorphic and fixed for the same allele in all populations. No more than seven loci were polymorphic within a single population. Genetic variability was expressed as the proportion of loci heterozygous in the average individual of a population. Heterozygosity in the three species of Neotoma studied averaged 0.078, a value within the range reported for other rodents. Although the levels of heterozygosity seen in Neotoma could not readily be explained, the variation may be attributed to ecological factors. The three species of Neotoma were compared on the basis of genetic similarity and found to form a close taxonomic unit, probably semispecies. Divergence times were obtained for the three species and found to compare well with divergence times obtained from fossil data. In general, the three species have diverged within the last 112,000 years during the Wisconsin glacial period.

From Theory to Practice: an Analytical Study of Sartre's Fiction

Description: The purpose of this study is to ascertain the major aspects of the theoretical structure of Sartrian existentialism and to examine the portrayal of these in Sartre's fiction. The theoretical investigation is based largely on Sartre's "L'Être et le néant" and "L'Existentialisme est u humanisme." The fictional works are "La Nausée," the trilogy "Les Chemins de la liberté," and "Le Mur." The study is prefaced by an examination of the term existentialism and a brief historical comparison of essentialist and existentialist philosophy. The aspects of Sartrian existentialism discussed are: the question of the existence of God and its importance to Sartre's philosophy; the premise of existence preceding essence; the fact of contingency on absurdity and its attendant nausea; the doctrines of freedom and responsibility; the dilemma of choice, anguish, and commitment; and the themes of authenticity, transcendence, and death.

Genic Differentiation and Evolution in the Ground Squirrel Subgenus Ictidomys (Spermophilus)

Description: The genetic structure of 26 natural populations of three species (S. tridecemlineatus, S. mexicanus, and S. spilosoma) of the Ictidomys subgenus of ground squirrels was analyzed using chromosomal and electrophoretic techniques. Chromosomal variation was not observed in S. mexicanus, and only slight karyotypic variation was found in the other two species. Chromosomal evidence indicated hybridization between S. tridecemlineatus and S. mexicanus, placing these species within the classical definition of semispecies. Analysis of electrophoretic variation at 29 genetic loci indicated close genetic relationships between these species. Evolution in Ictidomys appears to be linked with Pleistocene events, and speciation appears to have occurred within the last 155,000 years.
