Reentry For Formerly Incarcerated Individuals: A Focus On Workforce Reentry And Recidivism In Appalachia, Margaret E. Francisco

Electronic Theses and Dissertations

Formerly incarcerated individuals face challenges to successful reentry, a critical component of reducing recidivism and improving public health outcomes. These challenges are particularly acute in rural Appalachia, where structural disadvantages such as limited economic opportunities, healthcare access, and public transportation intersect with stigma and systemic barriers related to prior incarceration. This dissertation addresses these gaps through a mixed-methods examination of reentry and recidivism, grounded in public health frameworks and focused on the unique context of rural Appalachia.

This work includes three studies. First, a PRISMA-guided systematic review synthesized qualitative research on barriers and facilitators to employment following incarceration. Findings highlighted …

Promoting Metacognitive Awareness Through Exploratory Learning., Ryan J. Patrick

Electronic Theses and Dissertations

Exploratory learning engages learners in novel problem solving before direct instruction. This process is designed to lead learners to experience productive failure. Productive failure, however, has been shown to benefit learners by improving the recognition of knowledge gaps, relevant problem features, and deep structures. This allows learners to better attend to relevant information during the subsequent instruction and improves conceptual understanding. This dissertation investigates the role of metacognitive awareness during exploratory learning, in attempt to identify additional metacognitive mechanisms that support exploratory learning. Two experiments tested the theory that exploratory learning promotes metacognitive awareness in exploratory learning. Groups in both …

This study explores these motivations using self-determination theory, comparing LGBTQ+ and non-LGBTQ+ runners to identify differences in driving factors such as social connectivity, self-esteem, and competition. Additionally, it examines barriers LGBTQ+ runners face, ranging from structural obstacles to intrapersonal challenges, and how …

Predictor-Informed Bayesian Nonparametric Clustering., Md Yasin Ali Parh

Electronic Theses and Dissertations

In this dissertation, we performed clustering of observations such that the cluster membership is influenced by a set of predictors. To that end, we employ the Bayesian nonparametric Common Atom Model (CAM), which is a nested clustering algorithm that utilizes a (fixed) group membership for each observation to encourage more similar clustering of members of the same group. CAM operates by assuming each group has its own vector of cluster probabilities, which are themselves clustered to allow similar clustering for some groups. We extend this approach by treating the group membership as an unknown latent variable determined as a flexible …

Synthetic And Pharmacological Diversity Of Nitrogen-Containing Heterocycles., Shramana Ghosh

Electronic Theses and Dissertations

Nitrogen-containing heterocycles are a foundational class of compounds in organic chemistry, playing critical roles in pharmaceuticals, agrochemicals, and natural products due to their structural diversity and biological relevance. Among them, isoindolinones are notable for their wide range of pharmacological activities. Structurally, isoindolinones possess a benzylic methylene group adjacent to the nitrogen atom, which allows for selective oxidative transformations to yield phthalimide derivatives, well-known intermediates in synthetic, pharmaceutical, and materials chemistry. Although phthalimide is traditionally employed as a protecting group for amines via the Gabriel synthesis, isoindolinone offers a valuable alternative. Through a modified Gabriel-like approach, isoindolinones can serve as more …

However, the financial burden associated with trauma care, especially due to low-insured population, presents a significant challenge to the financial health of trauma centers (TCs). To address critical challenges in this domain and provide much-needed insights to trauma decision-makers regarding their trauma system cost, network design, and subsidy policy, this dissertation proposes 3 contributions. First, we introduce an …

The Substance Of Reality: Moral Perfectionism In Shakespeare's Hamlet., David Wright

Electronic Theses and Dissertations

Through a selection of and close reading of key passages, I offer an interpretation of Hamlet that seeks to illuminate the play as an important work of moral philosophy, and to situate the play within a strand of moral philosophy named moral perfectionism by Stanley Cavell. Indeed, Hamlet is a masterpiece of Renaissance drama, but when read with attention to moral perfectionism, the play yields additional layers of meaning. Hamlet is a “philosophical drama” that navigates the “moral calling of philosophy”—a text that seems to, almost uncannily, elicit the audience to think reflectively, to ask fundamental human questions along …

Polymathy: The Foundational Source Of Creativity And Innovation., Michael Araki

Electronic Theses and Dissertations

In an era of mounting complexity and a growing need to transcend siloed thinking, this dissertation advances polymathy as a critical yet underexplored construct in the management and behavioral sciences.

Isolation And Characterization Of Siderophore(S) From Pseudomonas Mosselii, Casey J. Stophel

Electronic Theses and Dissertations

Iron is essential for growth of most microorganisms. It functions as an important cofactor in many important biological processes. However, iron found in soil is rendered insoluble and unavailable to microorganisms for use. To overcome this, many bacterial species produce siderophores, a small organic molecule that has high affinity for iron. Siderophores allow for bacterial cells to obtain otherwise insoluble iron. Pseudomonas mosselii, a Gram negative bacterium, was isolated from a local soil sample. P. mosselii was found to produce siderophore(s) under iron restricted environment, however, they have not been characterized. Therefore, it was of interest to isolate, purify and …

Electrochemical And Electrocatalytic Properties Of Screen-Printable Carbon Inks Featuring Pyridinic Nitrogen-Containing Polymeric Binder, Albert Sam Junior

Electronic Theses and Dissertations

Screen-printable conductive inks have been widely applied to prepare electrodes for electrochemical sensing. These inks generally consist of conductive metal or carbon particles, solvents, and polymeric binders. Low-cost, carbon-based, screen-printable conductive inks are especially popular. However, screen-printed carbon electrodes (SPCEs) must often be modified after they are printed to impart the necessary characteristics (e.g., sensitivity, selectivity, stability) for the desired application. For example, nitrogen-doping of SPCEs, especially in ways that introduce pyridinic or pyrrolic nitrogen species, can impart electrocatalytic properties towards reduction of O₂, H₂O₂, and CO₂. While our previous work done …

Collaboration Across The Silos: Consultation As A Means For Integrating Services For Twice-Exceptional Learners, Kimberly Bowers Yoshino

Electronic Theses and Dissertations

Twice-exceptional (2e) learners are underserved in American schools. As students who demonstrate both giftedness and disabilities, 2e learners maintain profiles that warrant tailored educational services across special and gifted education programs. Yet, these programs are considered institutionally mutually exclusive as legal mandates create de facto isolation — the antithesis of what is recommended for the students’ optimal development. School psychologists have been identified as professionals critically positioned to support 2e learners because of their specialized skill set, namely in consultation. However, little is known about their consultative practices with the educators who serve 2e learners or how they traverse school …

Young Adults’ Metaperceptions Of Their Childhood Caregivers’ Appraisals And Young Adulthood Mental Health, Cassandra Svelnys

Electronic Theses and Dissertations

Early experiences and relationships have enduring impacts on the development of self and later mental health and wellbeing. In social relationships and interactions, the developing individual is continuously assessing how they view themself, how they view the other person, and how they believe the other person views them. Metaperceptions represent the latter construct: how an individual thinks another person perceives them. Childhood self-esteem, parent-child attachment, and metaperceptions are foundational constructs for the developing individual, yet metaperceptions have not previously been tested as a predictor for adulthood mental health while also accounting for childhood self-esteem and parent-child attachment. This study introduced …

Who Gets To Be A Child And When? The Pervasive Yet Contextually Shaped Nature Of Racialized Adultification Across Perceivers And Contexts, Kevin M. Summers

Electronic Theses and Dissertations

Racialized adultification is a pervasive bias in which individuals tend to judge Black children as older and more adult-like than White children of the same age. This racial bias is discussed across many scientific domains in addition to popular media, yet there is relatively little empirical work documenting its existence, consequences, and boundary conditions. In the current work, I aim to develop an empirical foundation that advances scientific understanding of racialized adultification and in turn contributes to a growing model that elucidates the conditions under which individuals are disproportionately likely to express this pernicious bias. In the current work, I …
