The differential impact of several teaching strategies upon the integration of economic concepts into the mathematics curriculum

Description: This investigation focuses upon two major problems. The first problem is to determine what effect the inclusion of economics in the mathematics curriculum will have upon student attitudes toward and understanding and retention of economics and mathematics. The second problem is to determine whether different methods of instruction will result in significantly different levels of student attitudes toward and understanding and retention of economics and mathematics.

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.

Induction of 16α Hydroxylase in Human Cultured Lymphocytes

Description: A method is presented for 160hydroxylase (SAH) induction in cultured human lymphocytes. SAH, a microsomal-associated enzyme, effects the oxidative conversion of 17pestradiol to estriol, which competes for cytoplasmic binding sites. 17,-estradiol and estrone are known mammary carcinogens, while estriol and its epimers have been suggested to have anticarcinogenic properties. To substantiate genetic variations of hydroxylase activity, an analysis of estrogen-induced cultured human lymphocytes was conducted to evaluate the frequency distribution of low, intermediate, and high SAH activity. Frequency analysis indicated that the control population distribution of SAH activity does not corroborate a proposed trimodal expansion of human SAH activity. A log normal distribution of SAH activity does exist, which suggests a polygenic mode of genetic control. SAH activity in a population of breast cancer patients and relatives of breast cancer patients showed no statistical difference from the SAH activity in the control population.

Infant-Caregiver Attachment and Separation: Single vs. Multiple Caregivers

Description: This study investigates (1) whether infants cared for by a single caregiver exhibit more attachment behaviors than do infants cared for by multiple caregivers and (2) whether sex differences are found in these behaviors. Twenty-six Black infants, nine to twenty-three months of age, in a day-care center, were observed during one brief low-stress separation from a caregiver. Data were taken using six indices of attachment: maintaining proximity, visual regard, touching, protesting, seeking proximity, and greeting. Where subjected to a two-way analysis of variance, the obtained results showed no significant differences in the effects of the two types of care. However, visual regard and greeting behaviors were observed significantly more frequently in females than in males.

Kinetics and mechanism of substitution reactions of tungsten carbonyl complexes containing bidentate sulfur ligands

Description: Previous investigation of the kinetics and mechanism of the substitution reaction of bidentate substituted transition metal carbonyl complexes with Lewis bases (L') to yield the cis distributed bidentate substitution product, where M=Cr, Mo, or W and S-S = DTO (2,2,7,7-tetra-methyl-3, 6-dithiaoctane) or DTN (2,2,8,8-tetramethyl-3,7-dithianonane) have suggested that this reaction proceeds via a mechanism involving initial reversible dissociation of one end of the bidentate sulfur ligand followed by rapid attack of L' on the resulting five-coordinate intermediate.

Linear Operators

Description: This paper is a study of linear operators defined on normed linear spaces. A basic knowledge of set theory and vector spaces is assumed, and all spaces considered have real vector spaces. The first chapter is a general introduction that contains assumed definitions and theorems. Included in this chapter is material concerning linear functionals, continuity, and boundedness. The second chapter contains the proofs of three fundamental theorems of linear analysis: the Open Mapping Theorem, the Hahn-Banach Theorem, and the Uniform Boundedness Principle. The third chapter is concerned with applying some of the results established in earlier chapters. In particular, the concepts of compact operators and Schauder bases are introduced, and a proof that an operator is compact if and only if its adjoint is compact is included. This chapter concludes with a proof of an important application of the Open Mapping Theorem, namely, the Closed Graph Theorem.

Machiavelli and Myth

Description: This work presented the question: to what extent did each period and its events have on the development of the various schools of thought concerning Niccolo Machiavelli. The age of Reformation in its quest for theological purity gave birth to the myth of the evil Machiavelli. The Enlightenment, a period which sought reason and science, founded the myth of the scientific Machiavelli. The eruption of nationalism in the nineteenth century created Machiavelli, the patriot, and this was quickly followed in the twentieth century, an age of unrest, by the rebirth of all previous interpretations. These schools of thought developed as much from the changing tide of events as from the scholarly research of the writers. One of the reasons for the diversity of the Machiavellian literature was that each writer sought his antecedents on the basis of myth rather than where it might realistically be found. Machiavelli and Machiavellianism were abused and misused because modern man did not know himself. He viewed his origin incorrectly and thus could rest on no one explanation for himself or -Machiavelli. Machiavellianism developed from a collection of myths, each started in an attempt to explain the unexplainable, man. Not Machiavelli's politics, but what man appeared to be in them, was the drawing power of Machiavelli's work. What Machiavelli meant to say or did not mean to say was unimportant when compared to what scholars believed him to have said.

Macro Control Structures for Structured Programming in ALC

Description: This thesis describes a set of computer program control structures which permits the application of certain structured programming techniques to the IBM/360 assembly language (ALC). The control structures are implemented by programmerdefined instructions known as macros. A history of computer software is presented, providing a basis for the emergence of structured programming. A survey of the major concepts of structured programming with special attention to control structures and their significance to structured programming follows. The macros developed in this study include DO, ENDDO, LEAVE, CASE, and ENDCASE. They provide a looping control structure, a loop-escape construct, and a selective control structure. Examples of usage are given.
