Laboratory Study On The Strength Behaviour Of Two Laterally Loaded Adobe Walls, Brad D. Weldon, Paola Bandini, Michael J. Mcginnis, Eduardo Dávila, Diego I. Garcia Vera

Civil Engineering Faculty Publications and Presentations

Adobe is a traditional construction technique found in historic and new construction throughout the world, often in earthquake-prone regions. Adobe structures are particularly susceptible to seismic forces due to their substantial mass and low tensile capacity. In addition, adobe is affected negatively by moisture that may penetrate from the ground or through the plaster. This paper describes the preliminary findings of an experimental program to investigate the effect of higher water content in the lower part of the wall on the wall strength behaviour under lateral loading. Lateral load tests were conducted on two quarter-scale adobe walls, one in air-dry …

Characterizing Ancient Chemoclines Through The Use Of Pigment Biomarkers And Sedimentary Stable Isotope Signatures, Benjamin T. Uveges

Dissertations - ALL

This dissertation focuses on identifying and qualifying chemocline dynamics, namely depth and stability, in stratified aquatic systems through the use of sedimentary pigments and the stable carbon and nitrogen isotopes of organic matter. The central aim of the research comprising this volume is to identify how chemocline fluctuations are expressed in the pigment and stable isotope signatures of aquatic sediments, and how those fluctuations may have impacted nutrient cycling in past intervals of marine anoxia and mass extinction.

In order to help gauge how the depth of the chemocline may affect specific pigment signatures and concentrations in sediments, I first …

A Smart Products Lifecycle Management (Splm) Framework - Modeling For Conceptualization, Interoperability, And Modularity, Yunpeng Li

Dissertations - ALL

Autonomy and intelligence have been built into many of today’s mechatronic products, taking advantage of low-cost sensors and advanced data analytics technologies. Design of product intelligence (enabled by analytics capabilities) is no longer a trivial or additional option for the product development. The objective of this research is aimed at addressing the challenges raised by the new data-driven design paradigm for smart products development, in which the product itself and the smartness require to be carefully co-constructed.

A smart product can be seen as specific compositions and configurations of its physical components to form the body, its analytics models to …

Development Of Explicitly Correlated And Many-Body Diagrammatic Techniques For The Investigation Of Electron-Hole Correlation In Nanomaterials, Michael Gray Bayne

Dissertations - ALL

The focus of this work is to develop theoretical methods that will accurately describe electron-electron and electron-hole correlation in nanoparticles using many-body diagrammatic techniques. Diagrammatic representation is a more complex representation of quantum mechanics, however, it becomes a more advantageous representation in its application to this work due to its ease of use. Diagrammatic techniques are essential to the ve methods presented here as they prove to be pivotal in theoretical development as well as providing useful information in extracting and visualizing fundamental physics to make useful approximations to the methods. In the projected congruent transformed Hamiltonian method with partial …

Experimental And Computational Analysis Of Relative Energetic Stabilities Of Crystalline Anhydrous Polymorphs And Pseudopolymorphs, Teresa Dierks

Dissertations - ALL

The stability of pharmaceutical solids is impacted by the properties of both active and inactive ingredients. Given that the aqueous solubility of solid-state medicinal products can be directly linked to the component properties, it is prudent to carefully study these materials to predict bioavailability and shelf stability. The relative energetic stabilities of the molecular crystals of interest are governed by both the intermolecular forces and the molecular conformations within the structure. In this research, the electronic origins of crystalline stability were investigated using a combination of solid-state density functional theory (ss-DFT) and terahertz time-domain spectroscopy (THz-TDS). Terahertz spectroscopy of the …

Adapting Proteins For Clinical And Industrial Use, Michelle Takacs

Dissertations - ALL

Enzymes are powerful tools that are capable of catalyzing reactions with high specificity and efficiency. Many naturally occurring enzymes are used as tools in industry and medicine, from food additives to pharmaceuticals to biofuel production. Protein engineering is used to make enzymes more readily available, to gain new or improved catalytic function, or optimize properties such as thermostability and enantioselectivity. In this thesis we will discuss the variety of ways proteins can be modified to one day be able to be put to use in industrial and clinical settings.

My goal has been to optimize proteins for industrial and clinical …

Sex Differences In Cardiovascular Adaptations To Chronic Endurance Exercise, Jacqueline A. Augustine

Dissertations - ALL

Endurance exercise typically leads to beneficial cardiac adaptations manifested as increased cardiac mass, higher cardiac function and lower central hemodynamic load (blood pressure, aortic stiffness and wave reflections). However, studies in male marathoners suggest detrimental cardiac remodeling, such that larger cardiac mass is associated with reduced cardiac function and higher central hemodynamic load. There are well-established sex differences in cardiac adaptations to endurance exercise and central hemodynamics across the lifespan. Whether there are sex differences in cardiovascular adaptations in marathoners requires further scrutiny. We examined sex differences in 1) Left ventricle (LV) structure, 2) LV function 3) 24-hour central hemodynamic …

Photolysis Kinetics Of Aromatic Pollutants In Liquid And Solid Environmental Condensed Phases, Alexa Stathis

Dissertations - ALL

Condensed phases in the environment are often chemically complex. Reactivity can differ significantly depending on the physical state (i.e. solid or liquid) and composition. Many laboratory studies that investigate reaction kinetics in condensed phases are done under simplified conditions that do not accurately reflect the complexity found in the environment. I have measured photolysis rate constants of the aromatic pollutants toluene, ethylbenzene, xylenes (TEX) and anthracene under environmentally-relevant conditions in order to improve fate predictions. The photolysis kinetics of TEX in water, ice and at ice surfaces were investigated using environmentally-relevant wavelengths. Previously, photolysis has not been considered a viable …

Comparative Ecophysiology Of Native And Invasive Plants Across Populations, Species, And Continents, Kelsey Anne Martinez

Dissertations - ALL

Invasive species are a persistent threat to biodiversity and agriculture that cost countries millions of dollars each year. Despite the scale and impact of the problem of invasive species, it remains a mystery why some introduced species become invasive and others remain benign. Here, I examined the theory that invasive species possess key traits which make them successful invaders. Specifically, I investigated the hypotheses that 1) plasticity increases invasive species’ success compared to native species, 2) invaders evolve rapidly in their new ranges, 3) invasive species avoid tradeoffs apparent in natives related to growth, resource use, or defense. Using 30 …

On Classification In Human-Driven And Data-Driven Systems, Qunwei Li

Dissertations - ALL

Classification systems are ubiquitous, and the design of effective classification algorithms has been an even more active area of research since the emergence of machine learning techniques. Despite the significant efforts devoted to training and feature selection in classification systems, misclassifications do occur and their effects can be critical in various applications. The central goal of this thesis is to analyze classification problems in human-driven and data-driven systems, with potentially unreliable components and design effective strategies to ensure reliable and effective classification algorithms in such systems. The components/agents in the system can be machines and/or humans. The system components can …

The Effect Of Fetal Programming On Physical Activity Behaviors, Jessica Garay Redmond

Dissertations - ALL

Appropriate fetal growth and development largely depends on the health and nutritional status of the mother. Exposure to a stressful intra-uterine environment leads to a series of adjustments, known as fetal programming, which have both short- and long-term implications. Immediately, the growth and development of the fetus is altered, resulting in intra-uterine growth restriction and a small size at birth. Long-term, individuals who experience fetal programming are at higher risk of developing certain chronic diseases.

In the current study, we examined the relationship between size at birth (an indicator of intra-uterine growth restriction and thus, fetal programming) and two main …

A Christmas Reflection, Eric F. Spina

President's Blog: From the Heart

In my annual Christmas message to students, faculty, and staff, I reflect on how the University of Dayton is more than our home away from home. It's a place in our hearts.

Schooling At The Intersection Of Refugee Identity And (Dis)Ability: Implications From North Korean Students With Refugee Backgrounds, Yosung Song

Dissertations - ALL

Researchers have previously found that school-age refugees and asylum-seekers are frequently characterized as experiencing physical, emotional, or psychological disabilities or disorders in schools because of the adversity that they face and a lack of adequate resources during their refugee journey. In their relocated society, many refugee students are interpreted as having disabilities or receiving special education services. While refugee experiences are often framed as causing deficits in students, the purpose of this study was to better understand the interplay of (dis)ability and refugee identity at a school that publicly proclaimed refugee experience as an asset. Grounded in a qualitative methodology, …

Tribal Tools & Legal Levers For Halting Fossil Fuel Transport & Exports Through The Pacific Northwest, Mary Christina Wood

American Indian Law Journal

As alarming scientific predictions crystallize into the realities of today’s climate crisis, tribal communities in the Pacific Northwest find themselves on the front lines of a global assault launched by the fossil fuel industry. Encouraged by President Trump’s declaration of intent to unleash $50 trillion of America’s domestic fossil fuels, corporations push for massive expansion of the nation’s fossil fuel infrastructure—even as the world races towards irrevocable climate thresholds. The unprecedented onslaught hinges on the Pacific Northwest as a key link in a global market scheme. The coastal region sits as a proposed industrial gateway for huge export facilities transporting …

The Effects Of Affective Arousal On Intentions To Engage In Sexual-Risk Behavior: An Experimental Study, Alan Z. Sheinfil

Theses - ALL

Despite decades of research on correlates of condom use, and numerous intervention development studies, condom use behavior remains inconsistent among adolescents and emerging adults as the incidence and prevalence of sexually transmitted infections continues to rise. One factor that may play a role in risky sexual decision-making is state affect, however, research investigating this relationship is equivocal. Therefore, the goal of this study was to examine the effects of experimentally induced affective arousal and affective valence on intentions to engage in condomless sexual activity in a sample of emerging adults. Based on the dual systems model of youth decision-making, it …

Constructions Of Masculinity In Bollywood Promotional Content, Alyssa Grace Lobo

Theses - ALL

Following a growing public discussion on violence against women in India, some commentators have turned their eye upon Bollywood. The film industry’s role in perpetuating models of courtship based on the stalking and harassment of women has drawn criticism from several quarters. While there has been much said about the depiction of women in Bollywood film, there has been relatively less said on portrayals of masculinity. The research that does exist focuses on textual analyses of films, or looks at masculinity through the lens of global capital flows. This thesis instead, analyzes trailers, posters, promotional pictures and social media for …

Exploring Specificity And Stability Of A Molecularly Imprinted Polymer, Stephen Robert Shepherd

Theses - ALL

Molecularly imprinted polymers (MIPs) have numerous practical applications, including integration with quartz crystal microbalances to make specific, stable, chemical sensors, but most published research literature does not provide details concerning the specificity or stability of such an imprinted polymer. A polymer made from polyacrylic acid monomers, templated with benzoic acid, was tested for specificity with solutions of benzoic acid, acetic acid, phenol, and terephthalic acid passed through samples of uniform size under vacuum filtration. Additionally, MIP samples were also stored for extended periods of time in varied microclimates and then tested for performance, and consequently, stability. Initial conclusions indicate that …

Four Phases Of Subjectivity: A Rhetorical And Phenomenological Analysis Of Aimé Césaire And Cahier D’Un Retour Au Pays Natal, Chelsea Binnie

Electronic Theses and Dissertations

This dissertation project sets out to perform a rhetorical and phenomenological analysis of the subjectivity that Césaire portrays in his epic poem Cahier d’un retour au pays natal, or Notebook of a Return to My Native Land. Césaire published and republished Cahier four times in a 17-year period and the modified accounts of subjectivity presented in the lines of the poem mirrors that of Césaire’s own human subjectivity. Césaire poetically unleashes Cahier and his Négritude project in an effort to shift the geography of reason from its self-appointed European center, to create a liminal space for the totalized …

Bullying Of Linguistically Diverse Learners: Results From The Youth Risk Behavior Survey, Jenna Woodarek

Electronic Theses and Dissertations

Bullying is a serious phenomenon yielding significant consequences for youth who are victimized, often targeted due to their perceived level of difference from their peers. This “otherness” can often be amplified in minoritized populations, especially those which have multiple, cooccurring vulnerabilities to be targets of bullying. After a period of bullying rates decreasing in the US, special interest group inquiries found bullying rates to be on the rise again and reportedly motivated by ethnicity or race, immigrant status, and proficiency in the English language. The present research study aims to expand upon the existing pertinent literature base specific to the …

Well-Trained Mentors: The Missing Component Of The Comprehensive New Teacher Induction Program In The Silver Oak Area School, Daniel Bosnic

Electronic Theses and Dissertations

“If well-trained, competent, caring teachers were present in every classroom, we would witness a staggering increase in student achievement, motivation, and character improvement along with a marked decrease in discipline problems” (Breaux & Wong, 2003, p.22). If school districts do not take the initiative to design and implement effective induction programs with embedded mentoring, they are essentially setting their teachers and students up for failure. Regardless of educator training programs, new teachers are unprepared to face the diverse and challenging needs of education today (Bartell, 2005). All individuals entering education need assistance in applying their prior knowledge and experience to …

A Disability Theology Of Limits For Responding To Moral Injury, Lisa Hickman

Electronic Theses and Dissertations

The lament of Jeremiah, “they dress the wound of my people as if it were not serious,” reverberates today as veterans return home from a decade of war, ridden by PTSD and moral injury, only to discover lethargy, lack of seriousness and complacency in societal response. The seriousness of our soldiers’ wounds, to body and spirit alike, demand ethical, societal and theological responsibility. Failure to address the seriousness of these wounds results in distress, depression and even suicide for the soldier. Statistics may describe a portion of the reality, but the degree to which soldiers suffer in silence and the …

Discarnation: Expounding On Marshall Mcluhan's Critique Of Modern Subjectivity, Amanda Sevilla

Electronic Theses and Dissertations

This project presents Marshall McLuhan’s work as an explication of discarnate subjectivity in mediated environments, with special focus on the consequences of technological environments in society. The first and second chapters focus on McLuhan’s ground, sensibilities, and practice to shed light on his intricate discussions of social perceptions emerging in modern times—i.e., communal awareness propels perceptual and cultural shifts. The third chapter attends to people’s perceptual compass, or their ability to interpret the world around them. Chapter four considers some of the phenomenological aspects of McLuhan’s probes. The ideas show disconnects between time and space that contribute to discarnation in …

Low Temperature Thermochronologic Constraints Across The East-Central Denali Fault: Evaluating Vertical Tectonics Along A Transpressive Orogen, Thomas Stuart Warfel

Theses - ALL

The Denali Fault is an active intracontinental structure located ~500 km north of the southern Alaskan plate boundary. In 2002, a M 7.9 earthquake initiated on a previously unmapped thrust fault subsidiary to the Denali Fault (Susitna Glacier Thrust) and propagated ~227 km eastward along the east-central segment of the Denali Fault and the Totschunda Fault. The objective of this thesis is to evaluate how fault geometry and rheologic strength control spatial-temporal patterns of exhumation along large-scale transpressive structures. Apatite fission track (AFT) thermochronology and apatite (U-Th)/He (AHe) dating are used on a combination of bedrock and cobble samples to …

Static Enforcement Of Termination-Sensitive Noninterference Using The C++ Template Type System, Scott Douglas Constable

Dissertations - ALL

A side channel is an observable attribute of program execution other than explicit communication, e.g., power usage, execution time, or page fault patterns. A side-channel attack occurs when a malicious adversary observes program secrets through a side channel. This dissertation introduces Covert C++, a library which uses template metaprogramming to superimpose a security-type system on top of C++’s existing type system. Covert C++ enforces an information-flow policy that prevents secret data from influencing program control flow and memory access patterns, thus obviating side-channel leaks. Formally, Covert C++ can facilitate an extended definition of the classical noninterference property, broadened to also …

Gaseous State: A Historical Geography Of Natural Gas And The Capitalist State In An Age Of Climate Change, Carlo Sica

Dissertations - ALL

In the 1930s U.S., a set of social forces and crises pushed forward state energy regulation. As states struggle to end greenhouse-gas emissions from fossil fuels, the threat of climate change demands new explanations for how energy policy emerges. In this dissertation, I explain the period of U.S. natural gas regulation between 1938 and 1978 from critical political economy and Marxist state theoretical perspectives. My main conclusion is that the capitalist state stabilizes markets for energy to serve capital with an auxiliary means of production. Based on that conclusion, I recommend that Marxist state theory be class-centered, i.e., recognize that …

Seeing And Believing: Philosophical Issues In Theory Of Mind Development, Joseph A. Hedger

Dissertations - ALL

All human beings understand the behaviors of others as causal results of their mental states. Philosophers call this ability folk psychology and developmental researchers call it theory of mind (ToM). My dissertation concerns how this reasoning works and how it is acquired.

First, I develop and expand a theory of how folk psychology develops in childhood. This is the Perceptual Access Reasoning, or PAR theory of the Fabricius lab. Contrary to the two views dominant in the field, I argue that ToM (belief reasoning or BR) is acquired around 6 years of age after undergoing two preliminary cognitive stages, reality …
