Show moreThe utilization of fuzzy mathematical modeling for quantification of the quality of training and educational delivery is an innovative application that can result in measurable and repeatable results. This research was designed to apply proven quantification techniques and Industrial Engineering methodologies to a nontraditional environment. The outcomes of this research provide the foundation, initial steps and preliminary validation for the development of a systematic fuzzy theoretical model to be applied for the quantification of various areas within training and education delivery. The test bed for this methodology is Orange County Public School system, the twelfth largest school district in the nation. The organizational and operational factors of a large school district are highly compatible with Systems Engineering concepts. The debate over education reform has drawn from referenced areas within the Industrial Engineering community including quality, continuous improvement, benchmarking and metrics development, data analysis, and scientific/systemic justification requirements. In spite of these applications, the literature does not reflect a consistent and broad application of these techniques in addressing the evaluation and quantification of educational delivery systems. This research draws on the previously listed areas within Industrial Engineering to apply these techniques to enhance the understanding and promote quantification of the multiple factors acting on the educational delivery system. The importance of addressing these issues is a national concern given the significant changes in the United States educational delivery system. For example, over the past 40 years there has been a more than three-hundred percent increase in per-pupil appropriations yet the academic performance gains have been limited and the quantification and measurement of those gains is even more limited. This body of work willidentify the systems, sub-systems, system factors, and factor degrees of existence necessary to quantify and measure these performance changes. Finally, the research will quantify the inputs and produce a model that provides a numeric value that represents the condition of the system and various subsystems of an educational system.

Defensive alliances are a way of using graphs to model the defense of resources (people, buildings, countries, etc.) against attacks where the number of potential attackers against each resource is known. The initial study of defensive alliances focused on questions of minimal defensive alliances in a graph and the minimum possible size of a defensive alliance in a graph, but in order to apply defensive alliances in modeling real-world situations, additional considerations are important.

Show moreDefensive alliances are a way of using graphs to model the defense of resources (people, buildings, countries, etc.) against attacks where the number of potential attackers against each resource is known. The initial study of defensive alliances focused on questions of minimal defensive alliances in a graph and the minimum possible size of a defensive alliance in a graph, but in order to apply defensive alliances in modeling real-world situations, additional considerations are important. In particular, since each vertex in a defensive alliance represents some real-world object that has a cost associated with remaining in the defensive alliance, it is important to consider the value each vertex adds to the defensive alliance. In this thesis we consider a method of assessing the efficiency of a defensive alliance, including the special case of secure sets.

Show moreThe following research is a content analysis of 114 articles written by the American and British news media outlets in the first month following the BP Gulf oil spill in April 2010. The goal of the research was to identify any dominant frames evident in the reports and to compare the two countries to see if there was a difference in the dominant frames used. Positive, negative, and neutral tones were also evaluated to determine if there was a difference between the countries. The results show that both countries reports predominantly used an ecology and action frame, while British media outlets also used an economic frame. Both countries reported with primarily a negative and neutral tone. The implications of these findings for crisis communication managers are discussed.

Show moreThis study assesses factors influencing the responsiveness of government officials in Alabama, Mississippi, and South Carolina regarding the public display of the Confederate Flag on state grounds in the aftermath of the Charleston, South Carolina shooting. The purpose of this dissertation research is to understand the factors influencing how government officials make decisions during racially/culturally sensitive events. Two research questions frame this study: 1) What factors are relevant to understanding state government officials' decision- making regarding the display of the Confederate Flag on public grounds? 2) Under what conditions of public decision making regarding the Confederate flag is executive authority, vote/referendum, or legislative processes used? Employing grounded theory across newspaper content in Alabama, South Carolina, and Mississippi, 117 articles were examined to provide insight into the research questions. The themes which emerged from this analysis are: 1)Key factors in the decision-making regarding the display of the Confederate Flag on state grounds are: a.The response to a triggering crisis event b.A desire for inclusiveness c.A perception of outside attention or scrutiny d.A concern for the economic well-being of the State e.The political agency of the decision maker 2)Economics, standing law, and political expediency influence decisions of whether executive authority, vote/referendum, or legislative processes are used in decision-making regarding the display of the Confederate Flag on public grounds. This study introduces a detailed model of decision-making for public officials in racially/culturally sensitive matters to navigate the handling of issues with similar schema-forming symbols which can call forth dynamic and polarizing responses. The findings from this research study can be used to foster improved government efforts at responding to matters of a highly charged emotional nature.

Show moreEase of use differentiates products in a highly competitive market place. It also brings an added value that culminates in a higher degree of customer satisfaction, repeated business, increased sales, and higher revenue. User-centered design is a strategic asset that companies can use to improve their customer relationships by learning more about their customers, and increase their sales. In today's economy, the measurement of intangible assets such as user experience has become a major need for industries because of the relationship between user-centered design and organizational benefits such as customer loyalty. As companies realize that the inclusion of user-centered design concepts in product or system design are a key component of attracting and maintaining customers, as well as increasing revenue, the need for quantitative methods to describe these benefits has become more urgent. The goal of this research is to develop a methodology to characterize user-centered design features, customer benefits and organizational benefits resulting from developing products using user-centered design principles through the use of an integrated framework of critical factors. Therefore, this research focuses on the identification of the most significant variables required to assess and measure the degree of user-centered design (UCD) characteristics included in the various aspects of product development such as physical design features, cognitive design attributes, industrial design aspects and user experience design considerations. Also this research focuses on the development of assessment tools for developers to use when evaluating the incorporation of user-centered design features in the creation of products and systems. In addition, a mathematical model to quantify the inclusion of UCD factors considered in the design of a product and systems is presented in this research. The results obtained using the assessment tools and the mathematical model can be employed to assess the customer benefits and organizational benefits resulting from including user-centered design features in the creation of products and systems. Overall, organizational benefits such as customer loyalty, company image, and profitability are expected to be impacted by the company's capability to meet or exceed stated design claims and performance consistency while maintaining aesthetic appeal, long product life, and product usefulness. The successful completion of this research has produced many beneficial research findings. For example, it has helped characterize and develop descriptors for estimating critical quantitative and qualitative components, sub-components, and factors influencing user-centered design that are related to customer and organizational benefits through the use of fuzzy set modeling. In addition, the development of specific tools, methods, and techniques for evaluating and quantifying UCD components resulted from this study.

Show moreThe objective of the research was to develop and validate a multifaceted model such as a fuzzy Analytical Hierarchy Process (AHP) model that considers both qualitative and quantitative elements with relative significance in assessing the likelihood of falls and aid in the design of NASA Ground Support Operations in aerospace environments. The model represented linguistic variables that quantified significant risk factor levels. Multiple risk factors that contribute to falls in NASA Ground Support Operations are task related, human/personal, environmental, and organizational. Six subject matter experts were asked to participate in a voting system involving a survey where they judge risk factors using the fundamental pairwise comparison scale. The results were analyzed and synthesize using Expert Choice Software, which produced the relative weights for the risk factors. The following are relative weights for these risk factors: Task Related (0.314), Human/Personal (0.307), Environmental (0.248), and Organizational (0.130). The overall inconsistency ratio for all risk factors was 0.07, which indicates the model results were acceptable. The results show that task related risk factors are the highest cause for falls and the organizational risk are the lowest cause for falls in NASA Ground Support Operations. The multiple risk factors weights were validated by having two teams of subject matter experts create priority vectors separately and confirm the weights are valid. The fuzzy AHP model usability was utilizing fifteen subjects in a repeated measures analysis. The subjects were asked to evaluate three scenarios in NASA KSC Ground Support Operations regarding various case studies and historical data. The three scenarios were Shuttle Landing Facility (SLF), Launch Complex Payloads (LCP), and Vehicle Assembly Building (VAB). The Kendall Coefficient of Concordance for assessment agreement between and within the subjects was 1.00. Therefore, the appraisers are applying essentially the same standard when evaluating the scenarios. In addition, a NASA subject matter expert was requested to evaluate the three scenarios also. The predicted value was compared to accepted value. The results from the subject matter expert for the model usability confirmed that the predicted value and accepted value for the likelihood rating were similar. The percentage error for the three scenarios was 0%, 33%, 0% respectively. Multiple descriptive statistics for a 95% confidence interval and t-test are the following: coefficient of variation (21.36), variance (0.251), mean (2.34), and standard deviation (0.501). Model validation was the guarantee of agreement with the NASA standard. Model validation process was partitioned into three components: reliability, objectivity, and consistency. The model was validated by comparing the fuzzy AHP model to NASA accepted model. The results indicate there was minimal variability with fuzzy AHP modeling. As a result, the fuzzy AHP model is confirmed valid. Future research includes developing fall protection guidelines.

Show moreEnhancing achievement in Science, Technology, Engineering, and Mathematics (STEM) is a long-standing national concern. The current national agenda, to instill an (")all hands on deck(") approach to creating a STEM literate citizenry, calls for broadening the scope of inclusion in STEM efforts. A critical population, higher education administrators, faculty, and staff are a valuable resource to advancing this agenda. Under the proposed Agenda Setting Communication Theory (ASCT) model developed for this study, their level of exposure to needed information is an important indicator of their potential participation in this agenda. As the leading news medium for the higher education community, the Chronicle of Higher Education was examined, through Content Analysis, to identify the frequency of reporting on STEM education from January 2001 to December 2015, to discern the themes in STEM education which appear in the Chronicle of Higher Education from January 2001 to December 2015, and to determine the frequency of reporting on the need for collaboration in STEM education in the Chronicle of Higher Education during that same period. The results of the Content Analysis indicate that there has been a significant increase in the Chronicle's reporting on STEM education in the past five years. Also, matters relating to the recruitment and retention of underrepresented populations were reported on most frequently. Further, reporting on the need for collaboration did not emerge as a primary theme. These results indicate that while the Chronicle is somewhat participating in reflecting aspects of the national STEM education agenda, it is not yet functioning to advance the breadth of that agenda within the higher education community.

Show moreThe core curriculum of interdisciplinary studies undergraduate programs represents interdisciplinarity as a consciously applied process, whether individually or collaboratively, of drawing and integrating insights from various disciplinary perspectives toward complex problem-solving and innovation. At the front-end of these programs students are often introduced to interdisciplinarity through terminology, metaphors, concepts, and context that are intended to familiarize them with the process. This initiation usually precedes what will ultimately entail a limited number of upper-division courses within the several disciplines or areas that will encompass a unique plan of study characterized by its breadth. The philosophy underlying current pedagogy in interdisciplinary studies appears in many ways to mirror the cognitive habitudes and socio-cultural zeitgeist that have emerged with our increasing connectedness with and reliance on digital technology.This dissertation proposes that through a revised front-end core curriculum revisiting both classical and Ramist pedagogy, and perhaps reframing how we think about interdisciplinarity itself, we need not sacrifice depth for breadth. Rather, we may be able to encourage a broadly applicable self-directed goal-centered mindset in our students that places equal emphasis on both breadth and depth in terms of deliberate knowledge acquisition. Through adapting the initial phases of a cognitivist instructional design model provisional week-by-week, curricular content is presented to illustrate how this endeavor might be realized within the context of interdisciplinary studies or like programs. This core curricular model is intended as an alternative well-suited to both the fully online and mixed mode format as well as the diversity of students within the typical undergraduate interdisciplinary studies program.
