Optimization Theory in Administrative Analysis

Optimization Theory in Administrative Analysis

Date: August 1970
Creator: Brown, Kenneth Sherron
Description: The thesis of this study is that modern optimization theory is a natural extension of classical optimization theory. As such, modern optimization theory will be applied to administrative problems only after interpretive studies are made that provide (1) an explanation of the general theoretical development of the techniques of modern optimization theory, (2) computational algorithms for implementing the techniques of modern optimization theory, (3) detailed demonstrations of the computational aspects of each technique and its corresponding algorithm, and (4) an identification of the types of problems to which these techniques are applicable.

Optimizing Non-pharmaceutical Interventions Using Multi-coaffiliation Networks

Optimizing Non-pharmaceutical Interventions Using Multi-coaffiliation Networks

Date: May 2013
Creator: Loza, Olivia G.
Description: Computational modeling is of fundamental significance in mapping possible disease spread, and designing strategies for its mitigation. Conventional contact networks implement the simulation of interactions as random occurrences, presenting public health bodies with a difficult trade off between a realistic model granularity and robust design of intervention strategies. Recently, researchers have been investigating the use of agent-based models (ABMs) to embrace the complexity of real world interactions. At the same time, theoretical approaches provide epidemiologists with general optimization models in which demographics are intrinsically simplified. The emerging study of affiliation networks and co-affiliation networks provide an alternative to such trade off. Co-affiliation networks maintain the realism innate to ABMs while reducing the complexity of contact networks into distinctively smaller k-partite graphs, were each partition represent a dimension of the social model. This dissertation studies the optimization of intervention strategies for infectious diseases, mainly distributed in school systems. First, concepts of synthetic populations and affiliation networks are extended to propose a modified algorithm for the synthetic reconstruction of populations. Second, the definition of multi-coaffiliation networks is presented as the main social model in which risk is quantified and evaluated, thereby obtaining vulnerability indications for each school in the system. Finally, maximization ...

Optimizing Scientific and Social Attributes of Pharmaceutical Take Back Programs to Improve Public and Environmental Health

Optimizing Scientific and Social Attributes of Pharmaceutical Take Back Programs to Improve Public and Environmental Health

Date: August 2012
Creator: Stoddard, Kati Ireland
Description: Research continues to show that pharmaceutical environmental contamination has caused adverse environmental effects, with one of the most studied effects being feminization of fish exposed to pharmaceutical endocrine disruptors. Additionally, there are also public health risks associated with pharmaceuticals because in-home reserves of medications provide opportunities for accidental poisoning and intentional medication abuse. Pharmaceutical take back programs have been seen as a remedy to these concerns; however a thorough review of peer-reviewed literature and publicly available information on these programs indicates limited research has been conducted to validate these programs as a purported solution. Furthermore, there are significant data gaps on key factors relating to take back program participants. The purpose of this dissertation was therefore to address these gaps in knowledge and ultimately determine if take back programs could actually improve public and environmental health. This was accomplished by conducting social and scientific research on a take back program called Denton Drug Disposal Day (D4). Socioeconomic, demographic, and geographic characteristics of D4 participants were investigated using surveys and geographic analysis. Impacts on public health were determined by comparing medications collected at D4 events with medications reported to the North Texas Poison Center as causing adverse drug exposures in Denton ...

An Oral Interpreter's Approach to Selected Poetry of Langston Hughes

An Oral Interpreter's Approach to Selected Poetry of Langston Hughes

Date: December 1971
Creator: Osentowski, Mary
Description: The purpose of this study was to analyze for oral presentation a selected body of poetry by Langston Hughes. Because Hughes read his own poetry in lecture recitals throughout his career, which spanned more than four decades, it is appropriate that he be considered for such a study.

Oral Syringe Training Animals: Indiscriminable and Discriminable Punishment Contingencies

Oral Syringe Training Animals: Indiscriminable and Discriminable Punishment Contingencies

Date: May 2013
Creator: Erickson, Emilie Jane
Description: Animals are commonly trained to perform behaviors during routine husbandry procedures. However, some husbandry procedures have aversive consequences when the real procedure is performed. This commonly results in loss of the trained behavior. The present study assessed whether maintaining the antecedent environmental stimulus conditions between appetitive and aversive outcomes would prevent this effect and, conversely, whether adding a stimulus discrepancy would facilitate this effect. Three domestic rats served as participants in a multiple baseline across participants design with multi-element components. All three rats stopped performing a trained behavior when a discrepant stimulus reliably predicted an aversive outcome. In addition, all three rats continued to perform the same behavior when antecedent environmental stimulus conditions were consistent between aversive and appetitive outcomes. Results are discussed in terms of practical implications for behavior change agents and conceptual implications for learning theory.

Orchestral Etudes: Repertoire-Specific Exercises for Double Bass

Orchestral Etudes: Repertoire-Specific Exercises for Double Bass

Date: August 2011
Creator: Unzicker, Jack Andrew
Description: In this project, frequently required double bass orchestral audition excerpts as well as their individual technical difficulties are identified. A survey of professional double bass players and teachers currently and formerly employed by major orchestras, universities, and conservatories have participated to validate the importance of four of the most frequently required orchestral excerpts: Ludwig van Beethoven’s Symphony No. 9, Mvt. 4, and Symphony No. 5, Mvt. 3; Richard Strauss’ Ein Heldenleben; and Wolfgang Amadeus Mozart’s Symphony No. 40, Mvt. 1. The survey respondents identified the primary and secondary technical concerns of each of the four excerpts. I have created technical studies, or etudes, that specifically address these difficulties and help fill a literary gap within the existing pedagogical resources for the double bass.

Order effects of variability-contingent and variability-independent point delivery: Effects on operant variability and target sequence acquisition.

Order effects of variability-contingent and variability-independent point delivery: Effects on operant variability and target sequence acquisition.

Date: May 2004
Creator: Lee, Coral Em
Description: Previous research has shown that variability is a reinforceable dimension of operant behavior. Additionally, it has been demonstrated that learning is facilitated when variability in responding is high. In this research, variability was observed within an operant composed of any sequence of six left and right key presses. Variability was either a requirement for point delivery (VAR conditions) or points were delivered independent of variability (ANY conditions). Two groups of college undergraduates experienced different orders of conditions. One group began the experiment under VAR conditions, and the variability requirement was later removed. The other group began the experiment under ANY conditions, and the variability requirement was later added. A concurrently reinforced target sequence (i.e., an always-reinforced sequence of left and right key presses) was introduced to both groups after these orders of conditions had been experienced. A variety of outcomes resulted. Subjects learned the target sequence when variability was both high and low with non-target points concurrently available. Other subjects learned the target sequence after all non-target point deliveries had been suspended. One subject failed to acquire the target sequence at all. These results were compared to previous findings and possible explanations for the discrepancies were suggested.
