Critical infrastructures (CI) play a vital role in majority of the fields and sectors worldwide. It contributes a lot towards the economy of nations and towards the wellbeing of the society. They are highly coupled, interconnected and their interdependencies make them more complex systems. Thus, when a damage occurs in a CI system, its complex interdependencies make it get subjected to cascading effects which propagates faster from one infrastructure to another resulting in wide service degradations which in turn causes economic and societal effects. The propagation of cascading effects of disruptive events could be handled efficiently if the assessment and …


The Self-Invalidation Due To Emotion Scale (Sides): Development And Psychometric Properties, Regina E. Schreiber May 2022

The Self-Invalidation Due To Emotion Scale (Sides): Development And Psychometric Properties, Regina E. Schreiber

Graduate Theses and Dissertations

Self-stigma involves internalized negative evaluation in people with a societally prescribed label (i.e., mental health diagnosis). Thus, measures of self-stigma due to mental illness exclude people without a diagnosis who may negatively evaluate themselves because of their emotions— a process we define as self-invalidation due to emotion. In the current research, I introduced a definition of self-invalidation due to emotion as distinct from self-stigma due to mental illness and emotion invalidation from others. After expert review of the item pool (Study 1), and exploratory (Study 2) and confirmatory factor analysis (Study 3), a 10-item scale for Self-Invalidation Due to Emotion …


Impact Of Genetic Variation And Timescale On Diatom Salinity Stress Response, Kala M. Downey May 2022

Impact Of Genetic Variation And Timescale On Diatom Salinity Stress Response, Kala M. Downey

Graduate Theses and Dissertations

Natural environments are dynamic, and organisms must sense and respond to changing conditions. One common way organisms deal with stressful environments is through gene expression changes, allowing for stress acclimation and resistance which occurs over varying time spans in different species. The recent evolutionary history of populations could greatly influence their ability to respond successfully. An evolutionary history in disturbed or fluctuating conditions could promote increased resistance or a more rapid response to these environmental stressors. To understand the impact of genotypic variation and timescales on response and acclimation to salinity changes, we have been exploiting the abilities of euryhaline …


Structural Checking Tool Restructure And Matching Improvements, Derek Taylor May 2022

Structural Checking Tool Restructure And Matching Improvements, Derek Taylor

Graduate Theses and Dissertations

With the rising complexity and size of hardware designs, saving development time and cost by employing third-party intellectual property (IP) into various first-party designs has become a necessity. However, using third-party IPs introduces the risk of adding malicious behavior to the design, including hardware Trojans. Different from software Trojan detection, the detection of hardware Trojans in an efficient and cost-effective manner is an ongoing area of study and has significant complexities depending on the development stage where Trojan detection is leveraged. Therefore, this thesis research proposes improvements to various components of the soft IP analysis methodology utilized by the Structural …

Native American students have consistently scored less than their white peers on high school academic achievement tests, have the lowest high school graduation rates, and have the lowest college enrollment rates. Research has evidenced challenges and struggles Native American children are faced with that negatively effects their success in the classroom. Native American students often encounter a disconnect between their home and school life resulting in difficulties of navigating two opposing worlds. When Native American students are associated with negative stereotype’s indicative of Native American culture as opposed to the dominant culture, this creates a conflict between their cultural identity …


Cognitive Tribalism: A Social Doxastic Model, Robert Ragsdale May 2022

Cognitive Tribalism: A Social Doxastic Model, Robert Ragsdale

Graduate Theses and Dissertations

How are facemasks – seemingly innocuous artifacts of the biomedical industry – currently embroiled in cultural wars? What motivates popular rejections of scientific consensus and messaging about the reality and consequences of anthropogenic climate change or the COVID-19 virus and vaccine? The puzzle is that (a) despite its being in everyone’s rational interests to have a well-informed public and body politic about collective threats, and (b) despite the public availability of accurate and reliable information, scientific messaging and public discourse surrounding climate change, COVID-19, and vaccine hesitancy, nevertheless, tend to be hijacked by political interest. Yet, if belief is essentially …


Economic Experiments On Group Identity And Bias, Nathaniel Christopher Burke May 2022

Economic Experiments On Group Identity And Bias, Nathaniel Christopher Burke

Graduate Theses and Dissertations

Experiments in economics have been a valuable tool to understand the behavioral implications of incentives on the decision-making process. Particularly, aspects of decision making that cannot be observed in empirical data can be better isolated in an experimental setting such as bias and identity impacts. This dissertation uses three distinct experiments to further the understanding of individual biases, perceptions, and identity and how they impact the way people defer to these internal traits under incentives. This dissertation looks at how well individuals can make inferences about polling data that was collected from individuals susceptible to socially desirable responding. It also …

Por Una Vida Mejor: Educational Attainment For Latinos In The Nuevo South In The Pursuit Of A Better Life, Maria Ana Sandoval

Graduate Theses and Dissertations

Por una Vida Mejor, a sentiment that is shared amongst the Latino community. How this sentiment fares in the pursuit of higher education has been largely understudied. I analyze how Latino college students navigate the sociopolitical environment in Arkansas in their pursuit of middle-class certification to help their family and fulfill the American dream. In this thesis I offer an analysis to understand Latinos in the Nuevo South. I use data from the 2021 Latino College Students Navigating the Sociopolitical Environment in Arkansas survey through the lens of Funds of Knowledge (Velez-Ibanez and Greenberg 1992). I conduct a quantitative analysis …


Possession: The Struggle For Female Bodily Agency In Exorcism Cinema, Michelle Lynne Pribbernow May 2022

Possession: The Struggle For Female Bodily Agency In Exorcism Cinema, Michelle Lynne Pribbernow

Graduate Theses and Dissertations

A dominant trope of the possession genre of horror cinema is the spectacle of the white female body that extends beyond narrowly-proscribed boundaries as being too active, too loud, too sexual, and too uncontrolled. This excess is depicted as monstrous, revolting to patriarchal ideology and in need of containment. In this dissertation, I argue that the long-standing horror genre of possession narratives reveals social anxieties about a loss of control over the productive and reproductive capabilities of the undisciplined female body in U.S. patriarchal, white supremacist, late capitalist culture. This study critically examines three sets of possession films: the Paranormal …


Investigating Depth Estimation To Archaeological Magnetic Source Bodies, Jeremy G. Menzer Dec 2021

Investigating Depth Estimation To Archaeological Magnetic Source Bodies, Jeremy G. Menzer

Graduate Theses and Dissertations

Magnetometry is the most widely applied archaeo-geophysical technique. Current practice standards employ the technique to map only in a two-dimensional plan view fashion, but in deep geologic studies depth estimators are routinely applied to magnetic datasets. These estimators provide three-dimensional information to magnetic source-bodies. There are many different depth estimators employed in geologic study that all require various degrees of processing complexity. This study investigates two mathematically simple techniques, half-width rules and multi-height methods. Half-width rules are likely the oldest depth estimators within the field while multi-height techniques are but a minor footnote in the literature. The applicability of these …


Examining Risks To Honey Bee Pollinators Foraging In Agricultural Landscapes, Jon Zawislak Dec 2021

Examining Risks To Honey Bee Pollinators Foraging In Agricultural Landscapes, Jon Zawislak

Graduate Theses and Dissertations

Bee pollinators provide essential ecological services to wild plant communities, and addtremendous economic value to agriculture by improving both the quality and quantity of crop yield. Beekeepers are often contracted by growers to provide colonies of honey bees for pollination of high-value produce (fruits, vegetables and nuts). Many of the major commodity crops produced in the central and mid-southern United States are wind-pollinated (rice, corn, grain sorghum, wheat), or are sufficiently self-fertile (soybeans, cotton), and so do not require bee pollination in order to produce yield. Beekeepers still rely on these agricultural landscapes to support honey bee colonies when not …

Audience, Minah Kim Dec 2021

Audience, Minah Kim

Graduate Theses and Dissertations

My work, “audience,” reflects binary oppressions sensed and recognized in my private memory and psychological space of living as a transnational being. Linguistic and sensical cognition I(a vulnerable transnational individual) had, have easily been dis-esteemed and devalued by White-centric epistemology. By confronting the reality of history that shapes my thoughts, performance, names, and meanings, I emphasize transnationality as an opportunity to multiply visual tools, dialogues, and inter-connections of individuals. This work integrates moments of physical connection and accountability by utilizing multidisciplinary expression, including ceramics, writing, sound, and the movements of performers and of the audience. Like an interfusion between artists …

Economic Potash Fertilizer Rate Recommendations, Kimberly B. Oliver Dec 2021

Economic Potash Fertilizer Rate Recommendations, Kimberly B. Oliver

Graduate Theses and Dissertations

This thesis is comprised of two studies that estimate profit-maximizing potassium (K) fertilizer application rates for various crops across different time periods. Estimation of profit-maximizing fertilizer-K rate (K*) for both studies considered the initial soil test level of K (STK) and yield response information, as traditional recommendations do, and added crop price and the cost of fertilizer. Profit maximum occurs where the marginal revenue from additional yield is equal to the marginal cost of applying an additional unit of fertilizer-K. The first study calculated K* for corn (Zea mays) and cotton (Gossypium hirsutum) and compared results to previous studies on …

Engineering Fluorescently Labeled Human Fibroblast Growth Factor One Mutants And Characterizing Their Photophysics Properties Towards Designing Fret Assays, Mamello Mohale Dec 2021

Engineering Fluorescently Labeled Human Fibroblast Growth Factor One Mutants And Characterizing Their Photophysics Properties Towards Designing Fret Assays, Mamello Mohale

Graduate Theses and Dissertations

Human fibroblast growth factor one (hFGF1) belongs to a family of 22 FGF members produced by fibroblast cells. Cell signaling during physiological processes of angiogenesis and wound healing occurs when hFGF1 binds to its receptor (FGFR). However, when heterogenous homeostasis is not maintained, fibroblast cells exhibit excessive proliferation which can lead to a myriad of cancers. smFRET is an ultrasensitive distant dependent (1-10 nm) technique capable of resolving such heterogeneity in structural dynamics and binding affinities (Kd). Therefore, we successfully designed and characterized fluorescently labeled hFGF1 tracers which span the visible light region of the electromagnetic spectrum for use in …

Cover Crop Effects On Infiltration, Aggregate Stability, And Water Retention On Loessial And Alluvial Soils Of The Lower Mississippi River Valley, Shelby G. Lebeau

Graduate Theses and Dissertations

Cover crops are a widely considered practice to improve soil health in the form of erosion control, organic matter additions, and improving water-holding capacity. Despite the well-documented benefits, little is known about the effect of cover crops on soils in the Lower Mississippi River Valley (LMRV), an area historically dominated by intensive cultivated agriculture, with soils prone to erosion, and unsustainable aquifer withdrawals for irrigation. The main objective of this study was to evaluate the effects of cover crops [with cover crops (CC) and without cover crops (NCC)] on near-surface soil physical/chemical- and infiltration-related properties, aggregate stability, and water retention. …


Forced And Unforced Permafrost Changes In The Northern Hemisphere During 1901-2100, Hong Guo Dec 2021

Forced And Unforced Permafrost Changes In The Northern Hemisphere During 1901-2100, Hong Guo

Graduate Theses and Dissertations

Permafrost regions are very sensitive to rapid changes in climate and environment. In recent decades, there has been growing interest to better understand the permafrost degradation over the Northern Hemisphere in the context of human-induced climate change. Understanding permafrost dynamics is not only important for infrastructure but also for environmental protection in cold regions. In-situ permafrost measurements are important for assessing permafrost conditions. However, direct permafrost observations are sparse and asymmetrical in both spatial and temporal coverage. Active layer thickness (ALT) modeling is another approach that can overcome many of these limitations, but the models have large uncertainty in predicting …
