Investigation Of Geopolymer Based Soil Stabilization Methods For Expedient Airfield Pavement Surfaces, Brett Albertson Dec 2022

Investigation Of Geopolymer Based Soil Stabilization Methods For Expedient Airfield Pavement Surfaces, Brett Albertson

All Theses

The United States Air Force (USAF) has the unique capability of being able to interdict superior airpower anywhere, at any time. However, superior airpower is only as effective as the amount of time an aircraft can spend in a particular area. The closer an aircraft can get to the mission need, the more time that can be spent in the air, or the less time that must be spent moving in and out of the operational area. Through the use of skilled and experienced men and women, the USAF is able to apply expedient and unsurfaced airfield paving techniques that …

Iron Phosphate Glass For The Immobilization Of Dehalogenated Salt Waste, Matthew Aaron Page Dec 2022

Iron Phosphate Glass For The Immobilization Of Dehalogenated Salt Waste, Matthew Aaron Page

All Theses

Electrochemical reprocessing can be used to recycle presently stored nuclear fuel and consists of dissolving that used fuel in molten salt and the waste produced from these processes is a small amount of a high-level salt waste. Vitrification has been selected as the primary means of safely disposing high and low level radioactive waste. This is due to glass’ ability to incorporate many elements within its matrix, and it is chemically durable with the addition of network formers and other glass forming chemicals. With over 90,000 tonnes of nuclear waste in the United States, the avoidance of additional steps required …

A Snapshot Of Statelessness In The Western Hemisphere: Denationalization In Modern Day Dominican Republic, Javiela Evangelista Dec 2022

A Snapshot Of Statelessness In The Western Hemisphere: Denationalization In Modern Day Dominican Republic, Javiela Evangelista

PALARA: Publication of the Afro-Latin/American Research Association

In 2013, the Dominican Republic’s Constitutional Tribunal ruling 168/13 retroactively revoked the citizenship of over 200,000 Dominican nationals of Haitian descent, thus creating the fifth largest stateless population in the world and the largest in the Western Hemisphere today (IACHR 2015). The ruling simply made legal the longstanding, racialized and clandestine practice of converting Haitian descendant Dominican citizens into foreigners. The ruling, as well as the laws that precede it, demonstrate how anti-blackness and racialization are processes through which citizenship is measured and mobilized to reorder society and formalize hierarchies. Dominicans of Haitian descent who are stateless are habitually denied …

Investigating The Frictional Properties Of Organic Matter And Pore Structure Of Organic-Rich Shales With Atomic Force Microscopy And Scanning Electron Microscopy, Farnood Sobhbidari Dec 2022

Investigating The Frictional Properties Of Organic Matter And Pore Structure Of Organic-Rich Shales With Atomic Force Microscopy And Scanning Electron Microscopy, Farnood Sobhbidari

Earth & Environmental Sciences Dissertations - Archive

Understanding geomechanical properties of shales, such as stiffness properties and fracture toughness, is important in different areas of petroleum industry-related activities including fracturing efficiency, petroleum flow to the wellbores, and induced seismicity. Nanoscale to microscale experiments on shale samples require a much smaller sample compared to macroscale experiments. This is a major advantage because irregularly-shaped drill cuttings from shales can be used for experimental analyses, such as nanoindentation or atomic force microscopy (AFM). However, a characterization of mechanical properties at the nano- to micro-scale is a relatively new addition to classical geomechanical experiments on shales, and there is still lack …

Pedagogical Uses For Machine Translation: Korean L2 Writing, Manali Khandekar Dec 2022

Pedagogical Uses For Machine Translation: Korean L2 Writing, Manali Khandekar

2022 Fall Honors Capstone Projects - Archive

Korean is a particularly challenging language for English speakers due to its typological distance from English, and as such, learning Korean typically requires hundreds or thousands of additional hours of instruction to reach intermediate and advanced levels. One solution that this study analyzes is the use of a rapidly improving technology: machine translation (MT). Participants were tasked with producing a short composition in Korean and then trained to use MT-based strategies to improve their writing; they also completed pre- and post-surveys to gauge their attitudes toward machine translation. Results showed improvement in vocabulary choice and grammar as well as case/locative …

Exploring The Scp Wiki: Community, Digital Horror, And Apocalyptic Fiction, Justin M. Jones Dec 2022

Exploring The Scp Wiki: Community, Digital Horror, And Apocalyptic Fiction, Justin M. Jones

English Theses - Archive

The SCP is a body of user-submitted fiction broadly classified as horror and often compared to other user-submitted horror such as Creepypasta. While these comparisons have been made in research and among the SCP community, the SCP seems to function differently than other such sites. Very little research has been done on the SCP and what exists examines it as a work of horror and as an example of emerging online folklore. This thesis further expands upon this research by examining how the unique community participating on the SCP Wiki shapes the text, how the SCP is not just a …

The College Admissions Process For Returning Citizens And Ex-Offenders At A Small, Private Midwestern College, Donna Bradley

Dissertations

It is well-known that higher education faces the challenge of declining enrollment, particularly post-COVID. However, there is a population of students that higher education institutions may overlook, returning citizens and ex-offenders. Reintegration is a challenging endeavor for returning citizens and ex-offenders, without regard to the length of incarceration or the circumstances surrounding system-involvement. They face barriers and stigmatization while attempting to achieve some sense of normalization post-incarceration, including the pursuit of higher education. Using mixed methodology, specifically a qualitative case study and descriptive statistics, the extant research examined the college admission process for returning citizens and ex-offenders through the lens …

A Uniform Approach To Farm Animal Welfare Laws: Thought For Our Food Instead Of Food For Our Thought, Channing Burd Dec 2022

A Uniform Approach To Farm Animal Welfare Laws: Thought For Our Food Instead Of Food For Our Thought, Channing Burd

Journal of Food Law & Policy

We have all seen the commercials and know “Happy Cows Come from California,” but there is a larger issue hidden inside the phrase. Why should not all farm animals be happy, regardless of which state they were raised in? Why are only the cows in California happy, but not the chickens and the hogs as well? Farm animal welfare in the United States needs regulatory overhaul, and we needed it decades ago. This article will illustrate why regulatory overhaul is needed. First, we will examine how a new system of laws, which are part of a uniform code enacted by …

Federal Food Safety Framework: Where Does Seaweed Fit In?, Catherine M. Janasie Dec 2022

Federal Food Safety Framework: Where Does Seaweed Fit In?, Catherine M. Janasie

Journal of Food Law & Policy

When one mentions seaweed as food, what do you think of? The dried nori used to wrap your sushi roll or perhaps the seaweed salad on the side? In fact, seaweed has many uses, including as both a food source in its own right and as a food additive. While the seaweed market has been dominated by East Asian countries, seaweed is cultivated in about 50 countries, and the U.S. seaweed industry is steadily growing. The global seaweed industry is currently worth about $6 billion annually. Food products for human consumption account for about 85% of this value.

Sro Roles And Teacher Behavioral Intervention Strategies: An Analysis On Behavioral Approaches And Student Suspensions., Ivan Benitez

Electronic Theses and Dissertations

Recently there have been nationwide calls for schools to end their contracts with local police departments in efforts to remove school resource officers (SROs) due to their criminalizing effect on students. Aiming towards racial equity in safety and discipline, advocates have suggested re-envisioning discipline through a restorative lens to minimize student harm. One approach which has been promising in student outcomes are behavioral intervention strategies. The current study contributes to the literature by examining the direct effects of SRO roles and teacher behavioral intervention strategies on student suspensions. Using factor analysis, I found three SRO roles: law enforcement officer, mentor, …

Effects Of Top-Down Attention And Individual Differences On Recognition Memory And Recollective Experience., Anna Kelley Dec 2022

Effects Of Top-Down Attention And Individual Differences On Recognition Memory And Recollective Experience., Anna Kelley

Electronic Theses and Dissertations

Memory accuracy and detail hold practical importance, and psychology has studied means to improve memory. One such means is performing visually guided saccades immediately before a memory test. Previous work has found this intervention to improve memory performance, an effect dubbed Saccade-Induced Retrieval Enhancement or SIRE. The top-down attentional control account posits that SIRE occurs because saccades activate attentional control regions in the brain, which contributes to executing top-down attentional control when searching memory. The current experiment tested this account of SIRE by attempting to replicate previous results and investigating whether a different attentional task, the Revised Attention Network Test …

The Impact Of Volatile Organic Compound Exposure On Subclinical Biomarkers Of Cardiovascular Injury., Breandon Taylor Dec 2022

The Impact Of Volatile Organic Compound Exposure On Subclinical Biomarkers Of Cardiovascular Injury., Breandon Taylor

Electronic Theses and Dissertations

Pollution has been identified as the leading environmental cause of non-communicable disease and premature deaths globally. Volatile organic compounds (VOCs) are gaseous chemical constituents of pollution derived from a variety of sources, including industrial solvents and byproducts, automobile exhaust, tobacco smoke, cleaning supplies, and personal care products. VOCs are also abundant at various Superfund and Hazardous Waste Sites. Emerging data suggest that VOC exposure is associated with several adverse health outcomes, including cardiovascular disease (CVD). VOCs and their metabolites can potentially damage the endothelial lining of blood vessels, resulting in perturbed vascular function and vascular inflammation. We hypothesize that VOC …

A New Direction For Public Understanding Of Science: Toward A Participant-Centered Model Of Science Engagement., Christopher Rickels Dec 2022

A New Direction For Public Understanding Of Science: Toward A Participant-Centered Model Of Science Engagement., Christopher Rickels

Electronic Theses and Dissertations

Engaging the public with science is not an easy task. When presented, scientific findings, public health recommendations, and other scientific information filter through the personal values, beliefs, and biases of members of the public. Science communicators must contend with these differences in order to be effective in cultivating a public understanding of science. Given the importance of scientific understanding for living well in a complex world, increasing science understanding through science engagement is imperative. The field of public engagement with science is dichotomized by a public information deficit approach and a contextualist approach. The deficit approach prizes the factual content …

Metabolic Foundations Of Exercise-Induced Cardiac Growth., Kyle Fulghum Dec 2022

Metabolic Foundations Of Exercise-Induced Cardiac Growth., Kyle Fulghum

Electronic Theses and Dissertations

Regular aerobic exercise promotes physiological cardiac growth, which is an adaptive response thought to enable the heart to meet higher physical demands. Cardiac growth involves coordination of catabolic and anabolic activities to support ATP generation, macromolecule biosynthesis, and myocyte hypertrophy. Although previous studies suggest that exercise-induced reductions in cardiac glycolysis are critical for physiological myocyte hypertrophy, it remains unclear how exercise influences the many interlinked pathways of metabolism that support adaptive remodeling of the heart. In this thesis project, we tested the general hypothesis that aerobic exercise promotes physiological cardiac growth by coordinating myocardial metabolism to promote glucose-supported anabolic pathway …

Changing Public Perception Of Dementia: The Effect And Credibility Of Three Informational Models., Diana Hedrick Dec 2022

Changing Public Perception Of Dementia: The Effect And Credibility Of Three Informational Models., Diana Hedrick

Electronic Theses and Dissertations

Background: Since the 1970s, Alzheimer’s disease and dementia have been portrayed in a medicalized, symptom-focused manner to help spread awareness, improve diagnosis, and push for treatment research. In recent decades, there has been movement towards a biopsychosocial, person-centered approach that considers social and psychological factors that interact with biological diseases processes. Common biopsychosocial approaches retain an emphasis on deficits and symptoms. New research has integrated positive psychology constructs and dementia. This integration of positive psychology principles and dementia care and research has the potential to more accurately capture the experience of having dementia. Objectives: This dissertation tested how the portrayal …
