4d Epr Oximetry Imaging For 4d Bioprinting And Tissue Engineering, Sajad Sarvari

Graduate Theses, Dissertations, and Problem Reports (ETD)

Bioprinting, akin to 3D printing, employs cell-laden hydrogels such as GelMA (Gelatine Methacrylate) and Alginate instead of plastic or resin to create biological structures. The printing process followed by subsequent tissue maturation is known as 4D bioprinting, where the fourth dimension is time. Ensuring adequate and consistent oxygen, O2, supply within 3D bioprint volume over the entire maturation period process is crucial, as even transient hypoxia can impact cellular behavior and phenotypes. However, printing of fully developed vasculature remains an unresolved technical challenge. Several approaches to chemically (peroxides) or biologically (photosynthesis) generate oxygen during bioprint maturation have been proposed. However, …

Sexual Identity And Homophily: The Powerful Role Of Sexual Identity For Romantic Partner Selection, Lee Thorpe Jr

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation investigates the role of sexual identity on homophily, and its effects on romantic partner selection. The principle of homophily states that individuals tend to befriend and seek romantic partners who are most similar to themselves based on certain social characteristics (i.e., birds of a feather flock together). The majority of the homophily literature focuses on heterosexual friendships and coupling. Recently, homophily research has included sexual identity in their analyses. However, recent studies have only investigated friendship formation/bonds for lesbians and describing certain racial coupling types for individuals based on their sexual identity. I fill the lacuna in research …

An Evaluation Of A Human-Operant Effort Manipulation And Effects Of Effort Disparity On Renewal, Haleh Amanieh

Graduate Theses, Dissertations, and Problem Reports (ETD)

The relative effort of target and alternative responses during treatments using differential reinforcement of alternative behavior may impact the likelihood that a previously reduced target response will reemerge following a context change (i.e., “renewal”). The purpose of this study was to evaluate the role of an effort disparity between target and alternative responses in a human-operant arrangement. Eighteen college students clicked on one (Experiment 1) or two (Experiment 2) circles moving on a computer screen for points. In Experiment 1, the speed of the circle was manipulated as an index of effort such that three circle speeds (i.e., 50, 100, …

Investigating Changing Macronutrient Dynamics At A Plant, Microbe And Plant-Microbe Interactions Scale, Emel Kangi

Graduate Theses, Dissertations, and Problem Reports (ETD)

Nutrient limitation drives forest ecosystem processes by altering net primary production, belowground (C) investments, and microbial activity. As such, the availability of essential macronutrients, such as nitrogen (N) and phosphorus (P), can severely impact plant growth, microbial decomposition, and the strength of plant-microbial interactions. However, our understanding of plant and microbe responses to changing nutrient availability, and the extent to which nutrient availability affects plant-microbe interactions, remains somewhat limited. Therefore, in this dissertation, I aimed to investigate nutrient limitation on a plant, microbe, and plant-microbe interaction level. First, to connect the phenotypic responses of nutrient-limited plants to key molecular mechanisms, …

Hepatic Mrna Expression Of Innate And Adaptive Immune Genes In Beef Steers With Divergent Residual Body Weight Gain, Deborah Ologunagba

Graduate Theses, Dissertations, and Problem Reports (ETD)

Immune system function is critical to maintaining the health and increasing productivity of cattle, affecting both their growth and their disease resistance. In an efficient immune system, the liver assumes an integral function in detoxification and metabolic processes and contributes substantially to overall production and immunity. In this study, we evaluated the hepatic mRNA expression of genes involved in innate and adaptive immunity in crossbred beef steers with either a positive or negative residual body weight gain (RADG). Positive-RADG beef steers (n = 8; RADG = 0.76 kg/d) and negative-RADG beef steers (n = 8; RADG = -0.64 kg/d) were …

Slope Stability Below Historic Pre-Law Mine Benches In The Northern Coalfields Of West Virginia, Muhammad Ali

Graduate Theses, Dissertations, and Problem Reports (ETD)

ABSTRACT

Slope stability below historic pre-law mine benches in the northern coalfields of West Virginia

Muhammad Ali

Slope failures and landslides are commonly occurring geohazards in the state of West Virginia and in the Appalachian region due to weak geologic strata, steep slopes, a humid climate, geologically recent river incision, and human landscape modifications. Historic surface mining has resulted in large-scale landscape alterations. Surface mining conducted before the Surface Mine Control and Reclamation Act (SMCRA) of 1977 did not require reclamation to approximate original contour; as a result, remnant highwalls and mine benches are common throughout the state and region. …

Assessing The Effectiveness Of Crime Scene Measuring Techniques, Lauren M. Fagan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Crime scene mapping is the process of measuring and fixing items present in the crime scene to obtain a detailed to-scale map of the scene as found by the crime scene investigators. When bloodstain patterns are present, investigators must analyze the bloodstains to assist in determining where the blood-shedding event occurred. The volume of origin is determined through a manual stringing method that is labor-intensive and destructive.

Technological advancements have been made in other fields, such as land surveying, and were adopted by law enforcement-related fields. These advancements include electronic terrestrial scanners, like the total station, and three-dimensional scanners, like …

Through The Keyhole, Anna Higgins

Graduate Theses, Dissertations, and Problem Reports (ETD)

Through the Keyhole derives inspiration from the lyrical styles of Tchaikovsky and Rachmaninoff. The transformational form of the piece follows an organic growth process leading up to a true climax. The piece stops, yet it does not end, leaving the listener to feel incomplete. Two melodic themes shape the piece alongside timbral developments. The harmony helps to portray the emotional journey of the piece, changing slightly throughout.

Life Cycle Cost Model for Transit Buses

Connor Jack

Transit agencies battle with reducing emissions while trying to be cost effective. In 2009, the Transit Cooperative Research Program Report (TCRP) 132 presented a life cycle cost model to aid in procurement evaluation [1]. The model is a life cycle cost analysis tool to estimate the overall costs of procurement and compare alternative technologies [2]. The model concentrates on pre-2007 conventional diesel, diesel hybrid with first generation diesel particulate filters, gasoline hybrid, and compressed natural gas transit buses.

The objectives of this work are to implement battery electric technology into …

Investigating The Effect Of Using Humorous Threats In Recreation Area Rules Signage To Influence Behavioral Intentions, Jacob Timothy Vargas

Graduate Theses, Dissertations, and Problem Reports (ETD)

Communicating the importance of rules and warnings to visitors of recreational parks through signage can be difficult. However, it is one of the most important things to keep visitors safe. Oftentimes, these signs use fear of punishment or injury to discourage certain behaviors. According to studies following the Extended Parallel Processing Model (EPPM), using threats can backfire and cause visitors to use maladaptive fear responses to counteract a threat message if the content is too extreme or too psychologically close. Humor is a versatile tool that can be used to grab attention, temper perceptions, and influence decision-making. Comedians like Jon …

Burnout Among West Virginia Art Teachers In A Post-Pandemic World, Kevin Richard Trautwein

Addressing the issue of teacher burnout is crucial for maintaining a healthy and effective educational environment for both teachers and students. Millions of teachers in the United States feel the negative effects of burnout, especially art educators. Teacher burnout is a significant issue because it can have serious negative impacts on both teachers and students. The art education field is unique in that their style of teaching looks different compared to other subject areas. The art classroom is commonly viewed as a place to decompress, play with art materials, and bring out one's own creativity. It is also viewed as …

The Phylogeny Of Chasmataspidida, B.D. Voss

Graduate Theses, Dissertations, and Problem Reports (ETD)

Chasmataspidids are a group of Early Paleozoic (Middle Ordovician-Middle Devonian) chelicerates with an unclear phylogenetic placement. Though recent phylogenetic tests that include chasmataspidids support a monophyletic Chasmataspidida as sister to a Sclerophorata (Eurypterida+Arachnida) clade, very few previous phylogenetic analyses have sampled more than three of the fourteen currently recognized species. Without a robustly tested phylogenetic hypothesis, understanding macroevolutionary and biogeographic trends within chasmataspidids is difficult. Chasmataspidids also represent the earliest preserved euchelicerate in the fossil record, with Chasmataspis laurencii Caster and Brooks, 1956, dated to approximately 478 million years ago, and the group’s relationship to other euchelicerates has implications on …

Characterization And Evaluation Of Various Biochar Types As Green Adsorbents For Rare Earth Element Recovery From Aqueous Solutions, Oluwaseun Victor Famobuwa

Graduate Theses, Dissertations, and Problem Reports (ETD)

Rare earth elements (REEs) are members of the lanthanide family (atomic number 57 – 71). They are significantly important to the global economy due to their applications in renewable energy, defense, and medical industries. REEs are primarily derived from bastnaesite and monazite but may also be present in xenotime, cerite, alanite, and many other types of mineralization in lesser amounts. Due to the increasing demand for REEs and their criticality in the supply chain, the need to explore secondary sources of REEs has gained tremendous importance.

Secondary sources of REEs include but are not limited to acid mine drainage (AMD), …

Informing Standardized Wood Turtle (Glyptemys Insculpta) Population Monitoring: Influences Of Sampling Approach And Turtle Behavior On Model Estimation, Allyson N. Beard

Graduate Theses, Dissertations, and Problem Reports (ETD)

To better understand wood turtle (Glyptemys insculpta) population trends, two standardized population survey protocols were recently developed for use by state monitoring programs. The protocols were independently developed, tested, and deployed for population monitoring in the eastern and upper midwestern United States. It was unknown if the sampling designs result in similar detection success or if data from the two protocols are compatible for broad-scale analyses. Additionally, neither monitoring protocol includes a sampling design that allows for the separation of detection (p) into availability (p_a), and detection given availability (p_d). …

Active Uncertainty Representation Learning: Toward More Label Efficiency In Deep Learning, Salman Mohamadi

Graduate Theses, Dissertations, and Problem Reports (ETD)

The primary goal of this dissertation is to investigate and improve the efficiency of deep learning algorithms, especially within computer vision problem domains, from the perspective of label-efficiency. This investigation showed that deep learning algorithms are mostly notorious for the lack of uncertainty representation. Accordingly, we aimed to develop an array of deep learning frameworks rich with uncertainty representation. These frameworks are mainly within two current pillars of machine learning, deep active learning and self-supervised learning. These frameworks include deep active ensemble sampling for efficient sample selection within deep active learning, a two-stage ensemble-based general self-training approach for existing visual …

Modeling, Control, And Fault Detection Of Energy Systems Under Limited High-Confidence Data Scenarios, Selorme K. Agbleze

Graduate Theses, Dissertations, and Problem Reports (ETD)

Abstract

Modeling, Control, and Fault Detection of Energy Systems under Limited High-Confidence Data Scenarios

Selorme K. Agbleze

Utilizing process measurements for fault detection is an established approach for processes with adequate datasets. For systems with limited high-confidence data representing fault cases and some amount of low-confidence data, few quantitative hybrid techniques exist for performing fault detection. In real systems, it is time-consuming, expensive, and sometimes not productive to generate enough high-confidence data with fault characteristics of a specific process. The problem of limited high-confidence data scenarios may also arise due to process novelty, the need for new operating conditions, or …

The Relationship Between Moral Thought-Action Fusion And Scrupulosity Across Judaism, Christianity, And Islam, Kelsey Evey

Graduate Theses, Dissertations, and Problem Reports (ETD)

Scrupulosity is a subtype of obsessive-compulsive disorder (OCD) where individuals are upset by intrusive thoughts related to religious or moral issues. Current research suggests that scrupulosity occurs across the major world religions—including the Abrahamic religions (i.e., Judaism, Christianity, and Islam). Some research suggests that moral thought-action fusion (moral TAF), a dysfunctional belief that thinking something is equal to doing it, may only be pathological under certain circumstances (e.g., if it is not culturally normative). If this is true, the current cognitive model of scrupulosity may need to be amended to reflect how cultural differences impact the role of moral TAF …

Foreign Policy Reorientation: From Globalization To Nationalism, Abdullah A. Asiri

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation explores the foreign policy implications of the post-2010 resurgence of nationalism in the U.S., Europe, and other parts of the world. It explores the reorientation of foreign policy away from globalization and the post-Cold War expectations that include a rules-based order, the spread of democracy and human rights, and the free movement of capital, products, people, and information. Instead, the emerging nationalist foreign policies emphasize independence and national sovereignty, economic self-sufficiency and protectionism, and anti-democracy and universal values. These policies are also characterized in terms of limited and unilateral engagement and proneness to conflict and confrontation. This dissertation …

The Function Of Protein Glutamylation In Vision, Rawaa Aljammal

Graduate Theses, Dissertations, and Problem Reports (ETD)

Posttranslational glutamylation of protein has emerged as a novel candidate for cellular integrity. In a dynamic process, Tubulin Tyrosine Ligase Like proteins (TTLLs) introduce glutamate groups to their substrates, while Cytosolic Carboxypeptidases members (CCP1-CCP6) remove these glutamate groups. The outcome of this interplay is a wide range of substrates; each is glutamylated to a level crucial for its function.

Protein glutamylation is particularly abundant in neurons and in the axoneme of cilia and flagella. This distribution, along with the correlation between imbalanced glutamylation levels and compromised cellular functions, underscores the significance of protein glutamylation in maintaining cellular viability. However, the …

Parental Socialization Of General And Domain-Specific Self-Control In Adolescents, Matty Johnston

Graduate Theses, Dissertations, and Problem Reports (ETD)

Adolescent self-control appears to be an important competency to develop. It has pervasive links with various outcomes (e.g., educational, financial, and interpersonal) both during adolescence and into adulthood (Allemand et al., 2019, Moffitt et al., 2011). Adolescents often report lower self-control compared to adults, although individual levels of self-control vary widely between adolescents (Allemand et al., 2019, Romer et al., 2010). Despite its importance, very little is known about how self-control develops. Thus, the current study aims to examine the relationship between parents’ self-control and that of their teen children. To further understand how adolescents' self-control may be socialized by …

Factors That Influence Plans To Have Children: An Application Of The Theory Of Planned Behavior To Fertility Decision-Making Across The Reproductive Years, Amanda Chappell

Graduate Theses, Dissertations, and Problem Reports (ETD)

Fertility intentions include plans to have one or more children; intentions can be used to predict fertility behavior. The focus of the current study was to examine the influence of age and gender on factors involved in estimating fertility intentions (measured with 5 items), including attitudes (i.e., how one feels about becoming a parent; 13 items), norms (i.e., pressure from important others to have children; 5 items), and perceived control (beliefs about capability of becoming a parent; 4 items) in a U.S. sample. The study included a sample of N = 289 (51% men) participants (75.6% White) between the ages …

From The Pews To The Ballot Box: How Religion Shapes Voting Behavior In Ghana., Maxwell Afriyie Nimako

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation explores how religion shapes voting behavior in emerging democracies, focusing on the case of Ghana. Using the Afrobarometer survey, the first stage of the analysis shows that Pentecostals are not statistically different from Roman Catholics in terms of voting for the New Patriotic Party (NPP) presidential candidates in 2007-2008 and 2013-2014. However, in 2016-2017, Pentecostal voters seem to have behaved differently from Roman Catholic voters. The dissertation subsequently explores why this variation in voting patterns emerged. This dissertation argues that explicit religious appeals made by presidential candidates and explicit religious appeals made by Pentecostal leaders for presidential candidates …

The Picture Of (Mental) Health: A Photovoice, Narrative Inquiry, And Critical Participatory Action Approach To Music Major Mental Wellness, Paige Zalman

Graduate Theses, Dissertations, and Problem Reports (ETD)

Higher education is experiencing a mental health epidemic (Venit, 2022). There is unprecedented student demand for psychological services that colleges are unable to meet (Lipson et al., 2019a), leading to high rates of mental illness-related attrition (Koch et al., 2018). Two groups of students at particularly high risk of mental illness-related attrition are students with historically marginalized identities, whether by race, gender, income, or another factor (Eisenberg et al., 2013), and music majors, a group that has been shown to have greater rates of mental illness than students in other majors (Lipson et al., 2016; Spahn et al., 2004). While …

Reimagining The Refugee Figure: Survival Migration And Its After-Affects, Gabriella Pishotti

Graduate Theses, Dissertations, and Problem Reports (ETD)

As the refugee crisis continues to worsen, so too will the field of refugee literature continue to expand into new directions to account for shifts in the refugee figure and developing concerns of survival migrant writers. Drawing from the foundational work of scholars such as Sianne Ngai and Sara Ahmed, I use affect theory as an intervention into these contemporary refugee texts to posit a rethinking of how we analyze refugee stories as narratives of crisis. I employ an affective approach to demonstrate how the emergency of forced migration can be narratively depicted in an embodied way that fosters connection …
