The Association of Self-Directed Learning Readiness, Learning Styles, Self-Paced Instruction, and Confidence to Perform on the Job (open access)

The Association of Self-Directed Learning Readiness, Learning Styles, Self-Paced Instruction, and Confidence to Perform on the Job

Learning styles and readiness for self-directed learning were identified for 125 adult employees enrolled in self-paced training courses. The success of the self-paced instruction was measured by confidence to perform learned skills on the job. Confidence scores were compared across learning style types and self-directed learning readiness. It was concluded that self-paced training programs can be effective for a variety of learning style preferences. Additionally, adult employees who are highly self-directed will experience greater success in self-paced instruction than those less self-directed. The implication for businesses and academic institutions seeking to employ technology based, self-instructional programs is that a return on investment can be maximized by an examination of the target audience. Training programs which are self-paced may not generate the desired success which will translate into effective job performance for those adults who are not ready for self-directed learning.

The Relationship between Self-Reported Bulimic Behavior and Cardiovascular Reactivity to a Weight Stressor (open access)

The Relationship between Self-Reported Bulimic Behavior and Cardiovascular Reactivity to a Weight Stressor

This investigation sought to identify anxiety responses to weight measurement, assessed by verbal report and cardiovascular reactivity CCR3 (systolic blood pressure, diastolic blood pressure, heart rate), which might differentiate females with either high or low self-reported bulimic behavior. Secondar i ly,, the study attempted to examine specific autonomic nervous system (ANS) arousal patterns of each group over time. The Bulimia Test (BULIT), Body Dissatisfaction Scale (BD), and a demographic questionnaire were administered to 105 undergraduate females at The University of North Texas. Based on BULIT scores, females were divided into high or low bulimic behavior groups. Of the 105 females screened, forty participated in the experiment which consisted of four phases: relaxation, anticipation of weight measurement, weight measurement, and recovery. Subjects had no prior knowledge of the weight stressor until presentation during the experiment. Results showed that subjects' notion of ideal weight was substantially lower than measured weight. During weight measurement, all subjects reported increased anxiety although the high group reported significantly more anxiety. Contrary to prediction, no significant group differences in CR were found when repeated measures multivariate analysis of variance (MANOVA) was performed. Orthogonal polynomial trend analysis was done with pooled groups, resulting in significant within-subject trends for …

Kinetic and Chemical Mechanism of O-Acetylserine Sulfhydrylase-B from Salmonella Typhimurium (open access)

Kinetic and Chemical Mechanism of O-Acetylserine Sulfhydrylase-B from Salmonella Typhimurium

Initial velocity studies of O-acetylserine sulfhydrylase-B (OASS-B) from Salmonella typhimurium using both natural and alternative substrates suggest a Bi Bi ping pong kinetic mechanism with double substrate competitive inhibition. The ping pong mechanism is corroborated by a qualitative and quantitative analysis of product and dead-end inhibition. Product inhibition by acetate is S-parabolic noncompetitive, indication of a combination of acetate with E followed by OAS. These data suggest some randomness to the OASS-B kinetic mechanism. The pH dependence of kinetic parameters was determined in order to obtain information on the acid-base chemical mechanism for the OASS-B reaction. A mechanism is proposed in which an enzyme general base accepts a proton from α-amine of O-acetylserine, while a second enzyme general base acts by polarizing the acetyl carbonyl assisting in the β-elimination of the acetyl group of O-acetylserine. The ε-amine of the active site lysine acts as a general base to abstract the α-proton in the β-elimination of acetate. At the end of the first half reaction the ε-amine of the active site lysine that formed the internal Schiff base and the general base are protonated. The resulting α-aminoacrylate intermediate undergoes a Michael addition with HS‾ and the active site lysine donates its …

Population Policy Implementation and Evaluation in Less Industrialized Countries (open access)

Population Policy Implementation and Evaluation in Less Industrialized Countries

This study emphasizes the impact of family planning program components on contraceptive prevalence in less industrialized countries. Building on Lapham and Mauldin's "Program Effort and Fertility Decline" framework and policy evaluation's theory, the author developed two models to examine the impact of family planning programs on contraceptive prevalence and fertility under the constraints of socioeconomic development and demand for family planning. The study employed path analysis and multiple regression on data from the 1982 program effort study in 94 less developed countries (LDCs) by Lapham and Mauldin and 98 LDCs of the 1989 program effort study by Mauldin and Ross. The results of data analyses for all data sets are consistent for the most part. Major findings are as follows: (1) A combination of program effort and socioeconomic development best explains the variation of contraceptive prevalence. (2) Among socioeconomic variables, female literacy exerts the strongest direct and indirect influences to increase contraceptive prevalence and indirect influence to decrease total fertility rate. (3) Christianity performs a significant role in reducing contraceptive prevalence. (4) Among program effort components, availability and accessibility for fertility-control supplies and services have the most influence on contraceptive prevalence. (5) When controlling for demand for family planning, female …

Corporate Sale-and-Leaseback Transactions: An Examination of Corporate Incentives, Wealth Effects and Dealer Spreads (open access)

Corporate Sale-and-Leaseback Transactions: An Examination of Corporate Incentives, Wealth Effects and Dealer Spreads

There is a limited amount of research dealing with the wealth effects of sale-and-leaseback transactions, but previous research has focused predominantly on the tax effects of these transactions. The results of these studies have often been in conflict with one another. This dissertation shows that tax effects do play a role in determining the wealth effect of sale-and-leasebacks on stockholders, but there exists a framework of finance research that suggests several other factors could play a determining role as well.

The Disfigured Muse : Supreme Readers in the Poetry of Wallace Stevens (open access)

The Disfigured Muse : Supreme Readers in the Poetry of Wallace Stevens

In "Discourse in the Novel," Mikhail Bakhtin tells us that "Every discourse presupposes a special conception of the listener, of his apperceptive background and the degree of his responsiveness." My study of Wallace Stevens's poetry examines Stevens's "conception of the listener"—in the form of his intratextual readers, their responsiveness, and the shapes that responsiveness takes—and attempts to formulate out of that examination Stevens's theory of reading embodied in his canon of poems.

Mathematical Programming Approaches to the Three-Group Classification Problem (open access)

Mathematical Programming Approaches to the Three-Group Classification Problem

In the last twelve years there has been considerable research interest in mathematical programming approaches to the statistical classification problem, primarily because they are not based on the assumptions of the parametric methods (Fisher's linear discriminant function, Smith's quadratic discriminant function) for optimality. This dissertation focuses on the development of mathematical programming models for the three-group classification problem and examines the computational efficiency and classificatory performance of proposed and existing models. The classificatory performance of these models is compared with that of Fisher's linear discriminant function and Smith's quadratic discriminant function. Additionally, this dissertation investigates theoretical characteristics of mathematical programming models for the classification problem with three or more groups. A computationally efficient model for the three-group classification problem is developed. This model minimizes directly the number of misclassifications in the training sample. Furthermore, the classificatory performance of the proposed model is enhanced by the introduction of a two-phase algorithm. The same algorithm can be used to improve the classificatory performance of any interval-based mathematical programming model for the classification problem with three or more groups. A modification to improve the computational efficiency of an existing model is also proposed. In addition, a multiple-group extension of a mathematical programming model …

Self-Assessment of Literacy Growth in Young Children (open access)

Self-Assessment of Literacy Growth in Young Children

In this study, 78 kindergarten and first-grade children were interviewed about their writing to identify indicators of self-assessment. Writing samples for each participant were saved over a three month period, then compared and discussed by the child. Results indicated that these young children did engage in self:-assessment behaviors. The classroom teachers were asked to place the participants in their classes along a writing continuum known as a Writing Band. Graphs were presented to show the writing levels of the children by classroom. In addition, each classroom was surveyed to document events which promote literacy development within the framework of an integrated curriculum. Writing samples for each child were collected and kept in a portfolio. Participants were interviewed regarding the contents of the portfolio. Children in two of the kindergarten classes were interviewed using 5 samples collected over a 2 1/2 month time period, and all other participants were interviewed using 6 writing samples collected over a 3 month period. Findings indicated that not only did these young children recognize growth in their writing, but they also assessed that growth based on outward, physical features of their writing. The writing ability of each child at the beginning of the study did …

Edmund Spenser as Protestant Thinker and Poet : A Study of Protestantism and Culture in The Faerie Queene

The study inquires into the dynamic relationship between Protestantism and culture in The Faerie Oueene. The American Protestant theologian Reinhold Niebuhr makes penetrating analyses of the relationship between man's cultural potentials and the insights of Protestant Christianity which greatly illuminate how Spenser searches for a comprehensive religious, ethical, political, and social vision for the Christian community of Protestant England. But Spenser maintains the tension between culture and Christianity to the end, refusing to offer a merely coherent system of principles based on the doctrine of Christianity.

Chronic Ventricular Sympathectomy : Effects on Myocardial Metabolism (open access)

Chronic Ventricular Sympathectomy : Effects on Myocardial Metabolism

Chronic ventricular sympathectomy elicits changes in the coronary circulation, myocardial oxygen consumption and size of infarction resulting fromcoronary occlusion. These changes indicate a change occurring in the basic metabolism of the heart in response to the removal of its sympathetic nervous input. This hypothesis was tested using two groups of dogs, a shamoperated control and a ventricular sympathectomized group. The sympathectomy procedure was an intrapericardial surgical technique which selectively removes ventricular sympathetic input. Four weeks after surgery, left ventricular tissue samples were obtained and rapidly frozen to -80°C. Selected metabolic variables were then compared between the two groups.

Mr. Citizen: Harry S. Truman and the Institutionalization of the Ex-Presidency

In the last two decades of his life, Harry S. Truman formally established the office of the ex-presidency in the public eye. The goals he wanted to accomplish and the legislation passed to help Truman achieve these aims led the way for Truman and other former presidents to play a significant role in American public life. Men who had occupied the nation's highest office had a great deal to offer their country, and Truman saw to it that he and other former presidents had the financial and the institutional support to continue serving their nation in productive ways. Although out of the White House, Harry S. Truman wanted to continue to play an active role in the affairs of the nation and the Democratic party. In pursuing this goal, he found that he was limited by a lack of financial support and was forced to turn to the federal government for assistance. While Truman was active for more than a decade after he left Washington, his two most important legacies were helping push for federal legislation to provide financial support for ex-presidents and to organize and maintain presidential libraries. Truman believed that these endeavors were a small price for the …

The Impact of Student Thinking Journals and Generic Problem Solving Software on Problem Solving Performance and Transfer of Problem Solving Skills (open access)

The Impact of Student Thinking Journals and Generic Problem Solving Software on Problem Solving Performance and Transfer of Problem Solving Skills

This study examined the effects of specially designed thinking journal activities that have been attributed with encouraging reflective thinking, on instruction using generic, or content-free problem solving software. Sixty-three fourth grade students participated in four instructional sessions using a software package called Moptown Hotel. Students completed separate posttests that measured (1) performance on problems of the same kind as those used in instruction, and (2) transfer of skills to other kinds of problems. Scores of students who wrote thinking journals prior to testing were compared with scores of students who did not. Results indicate that students who wrote thinking journals performed the same as students who did not when tested on problems similar to those practiced in class. Tests in which students transferred their skills to word problems, however, produced significant differences. There was no significant difference between scores when averaged over all four weekly occasions. However, for the final session alone, students who wrote thinking journals scored higher on tests of problem solving transfer than students who did not (p < .01). The study also examined the relationship between the degree of metacognitive thought displayed in students' journal entries, and their measured problem solving ability. Results indicate that students …

Deterministic Brownian Motion (open access)

Deterministic Brownian Motion

The goal of this thesis is to contribute to the ambitious program of the foundation of developing statistical physics using chaos. We build a deterministic model of Brownian motion and provide a microscpoic derivation of the Fokker-Planck equation. Since the Brownian motion of a particle is the result of the competing processes of diffusion and dissipation, we create a model where both diffusion and dissipation originate from the same deterministic mechanism - the deterministic interaction of that particle with its environment. We show that standard diffusion which is the basis of the Fokker-Planck equation rests on the Central Limit Theorem, and, consequently, on the possibility of deriving it from a deterministic process with a quickly decaying correlation function. The sensitive dependence on initial conditions, one of the defining properties of chaos insures this rapid decay. We carefully address the problem of deriving dissipation from the interaction of a particle with a fully deterministic nonlinear bath, that we term the booster. We show that the solution of this problem essentially rests on the linear response of a booster to an external perturbation. This raises a long-standing problem concerned with Kubo's Linear Response Theory and the strong criticism against it by van …

The Musical Fallout of Political Activism: Government Investigations of Musicians in the United States, 1930-1960 (open access)

The Musical Fallout of Political Activism: Government Investigations of Musicians in the United States, 1930-1960

Government investigations into the motion picture industry are well-documented, as is the widespread blacklisting that was concurrent. Not nearly so well documented are the many investigations of musicians and musical organizations which occurred during this same period. The degree to which various musicians and musical organizations were investigated varied considerably. Some warranted only passing mention, while others were rigorously questioned in formal Congressional hearings. Hanns Eisler was deported as a result of the House Committee on Un-American Activities' (HUAC) investigation into his background and activities in the United States. Leonard Bernstein, Marc Blitzstein, and Aaron Copland are but a few of the prominent composers investigated by the government for their involvement in leftist organizations. The Symphony of the Air was denied visas for a Near East tour after several orchestra members were implicated as Communists. Members of musicians' unions in New York and Los Angeles were called before HUAC hearings because of alleged infiltration by Communists into their ranks. The Metropolitan Music School of New York, led by its president-emeritus, the composer Wallingford Riegger, was the subject of a two day congressional hearing in New York City. There is no way to measure either quantitatively or qualitatively the effect of …
