Steminism: Analyzing Factors That Improve Retention Of Women In Stem, Kira Carter, Jane Kelley, Jason Vasser-Elong, Rc Patterson
Steminism: Analyzing Factors That Improve Retention Of Women In Stem, Kira Carter, Jane Kelley, Jason Vasser-Elong, Rc Patterson
Dissertations
Our co-authored research ‘Steminism: Analyzing Factors That Improve Retention for Women as STEM Majors’ analyzed factors that contributed to the retention of women in science, technology, engineering, and mathematics (STEM) programs at Missouri University of Science & Technology (Missouri S&T). Women make up half of the US population, and while careers in (STEM) are an integral part of the US economy, women are underrepresented in these career fields. The purpose of our dissertation is to address the underrepresentation of women in STEM majors. Our methodology included homogeneous sampling to collect qualitative data. More specifically, we consulted with academic advisors and …
Optimizing Vaccine Supply Chains With Drones In Less-Developed Regions: Multimodal Vaccine Distribution In Vanuatu, Deng Pan
Dissertations
In recent years, many less-developed countries (LDCs) have been exploring new opportunities provided by drones, such as the capability to deliver items with minimal infrastructure, fast speed, and relatively low cost, especially for high value-added products such as lifesaving medical products and vaccines. This dissertation optimizes the delivery network and operations for routine childhood vaccines in LDCs. It analyzes two important problems using mathematical programming, with an application in the South Pacific nation of Vanuatu. The first problem is to optimize the nation-wide multi-modal vaccine supply chain with drones to deliver vaccines from the national depot to all health zones …
Academic Honesty, Professional Integrity, And Undergraduate Engineering Students: Exploring The Connections, S. Amy Skyles, Jeffrey W. Jennings
Academic Honesty, Professional Integrity, And Undergraduate Engineering Students: Exploring The Connections, S. Amy Skyles, Jeffrey W. Jennings
Dissertations
One benefit of inculcating professionalism into engineering degree program curricula is a measure of the extent to which future practitioners adopt an engineering code of ethics (Abaté, 2011; Davis, 2006). Studies have indicated more dishonesty among engineering students than other groups of undergraduate learners, but the effects of technology on dishonesty in the classroom was not addressed (Bowers, 1964; McCabe et al., 2012). An explanatory, sequential mixed methods study was designed to explain to what degree course pedagogical practices and attitudes of civil, architectural and environmental engineering students of various academic levels (freshman/sophomore and senior) relate to academic dishonesty. The …
Towards Completely Automated Glycan Synthesis, Matteo Panza
Towards Completely Automated Glycan Synthesis, Matteo Panza
Dissertations
Carbohydrates are ubiquitous both in nature as biologically active compounds and in medicine as pharmaceuticals. Although there has been continued interest in the synthesis of carbohydrates, chemical methods require specialized knowledge and hence remain cumbersome. The need for development of rapid, efficient and operationally simple procedures has come to the fore. This dissertation focuses on the development of a fully automated platform that will enable both experts and non-specialists to perform the synthesis of glycans. Existing automated methods for the synthesis of oligosaccharides are highly sophisticated, operationally complex, and require significant user know-how. By contrast, high performance liquid chromatography (HPLC) …
Functionalized Nanoporous Carbon Scaffolds For Hydrogen Storage Applications, Christopher Carr
Functionalized Nanoporous Carbon Scaffolds For Hydrogen Storage Applications, Christopher Carr
Dissertations
Recent efforts have demonstrated confinement in porous scaffolds at the nanoscale can alter the hydrogen sorption properties of metal hydrides, though not to an extent feasible for use in onboard hydrogen storage applications, proposing the need for a method allowing further modifications. The work presented here explores how the functionalization of nanoporous carbon scaffold surfaces with heteroatoms can modify the hydrogen sorption properties of confined metal hydrides in relation to non-functionalized scaffolds (FS). Investigations of nanoconfined LiBH4and NaAlH4indicate functionalizing the carbon scaffold surface with nitrogen can shift the activation energy of hydrogen desorption in excess of …
