Economic Background And The Role Of Self-Compassion, Dixy Melendez

Psychology and Counseling Theses

Although self-compassion is established as a buffer against psychological distress, few studies examine its protective role alongside socioeconomic discrimination. This study used hierarchical multiple regressions and a hierarchical logistic regression to examine subjective social status, downward classism, self-compassion, and internalized shame as predictors of distress, academic anxiety, and academic task choice among college students, controlling for demographic variables. Greater self-compassion predicted less internalized shame, and greater downward classism predicted greater shame and distress. Self-compassion showed only marginal protective effects against distress after accounting for other variables. Internalized shame was the strongest, most consistent predictor, robustly relating to academic anxiety and …

The Neuropsychological Analysis Of The Effect Of Shame And Traumatic Memories In Paranoia: A Network Analysis, Anwesha Maitra

Clinical Psychology Dissertations

Paranoia is increasingly recognized as a multidimensional psychological phenomenon influenced by trauma-related distress, shame, maladaptive interpersonal experiences, and emotional functioning. Although these factors have been extensively associated with paranoia, their relationships with neurocognitive functioning, social cognition, and global functioning remain less well understood. The present study examined these relationships using traditional statistical analyses, network analysis, and machine-learning approaches in a non-clinical sample of 42 adults.

Participants completed self-report measures assessing trauma-related distress, childhood interpersonal experiences, shame, paranoia, depressive symptoms, fear of negative evaluation, self-esteem, and hostile attribution bias, in addition to a comprehensive neurocognitive battery, an emotion recognition task, and …

Erk-Mediated Phosphorylation Of Yap Defines A Noncanonical Fgf Signaling Mechanism In Stem Cells, Xiaolei Zhao, Shannon Erhardt, Li Tang, Xiaotong Chen, Stephen M Farmer, Zixiu Cheng, Wen Chen, Ella Ziyuan Lu, Kihan Sung, Chang-Ru Tsai, Mingjie Zheng, Sheng Zhang, Yang Liu, Jianxin Wang, Min Li, James F Martin, Jun Wang

Faculty, Staff and Student Publications

While Fgf and Hippo-Yap signaling are fundamental for proper development, homeostasis, and disease, their crosstalk remains largely unknown. Here, we identified that Yap and Taz, canonical Hippo effectors, function as noncanonical effectors of Fgf signaling to maintain the proper function of neural crest (NC) lineages. NC cells are a multipotent stem cell population during vertebrate embryogenesis that contribute to numerous structures and diverse cell lineages, including craniofacial and cardiac tissues, neurons, and suture mesenchymal cells (SMCs), a specified cell population required for cranial bone growth and repair. We observed that activation of Fgf signaling in NC cells and NC-derived SMCs …

Automated Machine Learning And Satellite Image Data Fusion For Monitoring Water Quality In Mosaicked Landscapes, Sahar Rezaei

Graduate Theses and Dissertations

Despite the ecological, economic, and social importance of inland water bodies, they are increasingly impacted by human and natural drivers. Harmful algal blooms (HABs) and total suspended solids (TSS) are key indicators of water quality, and elevated concentrations pose significant ecological and public health risks. The spatiotemporal dynamics of these variables remain insufficiently understood in major river systems, including the Upper Mississippi River (UMR) and the Illinois River Basin (IRB). While in situ measurements provide accurate observations, they are costly and offer limited spatial and temporal coverage, restricting basin-scale monitoring. Remote sensing offers a powerful alternative; however, single-sensor approaches are …

Conflict-Mediated Group Size Regulation: A Theory Of Supraoptimal And Suboptimal Group Size, Eric Schniter

ESI Working Papers

Observed group sizes rarely match the size that would maximize what each member gets from belonging. We propose a two-part theory in which group size is regulated by two related conflicts: insider-outsider conflict over admission, and within-group conflict as crowding, competition, and social tensions intensify with size. Three strategies are available: admission, exclusion, and fission. The first part shows that even when exclusion is unavailable, fission dynamics alone drive group size away from the optimum in both directions, with the pattern set by how prospective joiners encounter groups and by the geometry of fission. When joiners compare groups across a …

Corn Yield And Tissue-Potassium Response To Potassium Fertilization, Wyatt A. Rongey

Graduate Theses and Dissertations

Potassium (K) deficiency is an increasingly important yield-limiting factor for irrigated corn (Zea mays L.) in Arkansas, where below optimum soil-test K (STK) acreage is increasing and visible K deficiencies or hidden K hunger threaten yield and profitability. Improving K management for modern, high-yielding hybrids require refining soil-test-based fertilizer recommendations and defining growth-stage-specific tissue-K sufficiency ranges that diagnose deficiency before irrecoverable yield loss occurs. This research aimed to i) quantify corn grain yield and yield component responses to K fertilization across a wide range of STK levels; ii) determine the frequency and magnitude of agronomically and economically meaningful yield responses …

Evaluation Of Loading, Release, And Bioavailability Of Resveratrol Encapsulated In Porous Starch, Yu-Yun Wang

Graduate Theses and Dissertations

Resveratrol (Res) is a polyphenolic compound found in grapes, red wine, and berries, with health benefits such as antioxidant, anti-inflammatory, and cardioprotective properties. The poor stability and bioaccessibility of Res after consumption by humans require the development of delivery systems. Among many delivery systems, porous starch (PS) is a safe, cost-effective, and high in adsorption capacity encapsulation material for drugs and bioactive compounds sensitive to environmental factors like light and heat. Porous rice, corn, and potato starch have different granule sizes, pore volumes, and surface areas. However, the impact of these encapsulation capabilities remains unclear among the three porous starches. …

Sigesn-Based Lasers On Silicon For Mid-Infrared Optoelectronics, Sudip Acharya

Graduate Theses and Dissertations

Germanium-tin (GeSn) alloys represent a significant advancement in semiconductor technology, particularly for applications in the short-wave and mid-infrared (SWIR and MIR) spectral ranges. As a group IV material system, these alloys offer a unique combination of tunable optoelectronic properties and full compatibility with established silicon-based manufacturing processes. The controlled incorporation of tin into germanium enables the engineering of a fundamental direct bandgap, a critical feature that distinguishes GeSn from its indirect bandgap materials, silicon and germanium. This direct bandgap behavior which was demonstrated in high-quality single crystalline GeSn alloys around the year 2015 is the foundation for efficient light emission …

“We Have The Right To Education”: Exploring Student Experiences, Disability Policy, And The Need For Culturally Refined Awareness Raising On Inclusive Higher Education Within The English-Speaking Caribbean, Kadesha Treco

Graduate Theses and Dissertations

Within the English-speaking Caribbean, research at the intersection of inclusive education policy and higher education (HIED) remains limited. Despite the ratification of the United Nations Convention on the Rights of Persons with Disabilities (2006) by countries across the region, the establishment of the CARICOM Special Rapporteur on Disabilities, and the creation of several pieces of national disability legislation, there is little evidence regarding the effectiveness of these initiatives at improving access to HIED. Therefore, this dissertation contributes to regional scholarship on inclusive education by examining how access to, and experiences within HIED institutions are shaped for students with disabilities. This …

Beyond Access: Native American Students' Sense Of Belonging At Land-Grant Pwis, Skyler Ames-Patton

Graduate Theses and Dissertations

Native American students remain one of the most underrepresented populations within higher education and continue to experience unique challenges related to belonging, visibility, and persistence, particularly within predominantly White institutions (PWIs). Although sense of belonging has been widely recognized as a significant factor influencing student success and retention, traditional approaches to belonging often fail to account for distinct cultural, historical, and relational experiences that shape Native students’ educational journeys. This study explores how Native American students describe their interpersonal experiences and sense of belonging at a public, land-grant, PWI in the mid-South region of the United States. Guided by Tribal …

Advancing Social Media Analytics And Personalized Generation Via Transfer Learning, Discourse-Aware Modeling, And Collaborative Modeling, Gibson Nkhata

Graduate Theses and Dissertations

Social media platforms have become central to information exchange, shaping public opinion across social, political, and economic domains. However, the massive volume of user-generated content, combined with its informal, nuanced, and often noisy nature, presents significant challenges for automated analysis and generation. Tasks such as stance detection, rumor verification, and personalized content generation are further complicated by sarcasm, evolving discourse structures, and diverse user preferences. Addressing these challenges requires models that can effectively leverage linguistic nuance, conversational dynamics, and collaborative user signals. Transfer learning has emerged as a powerful paradigm for improving performance in low-resource and complex language understanding tasks. …

Effectiveness Of Pcit With Toddlers In A Community-Based Sample: Special Considerations For Youth With Neurodevelopmental Conditions, Rebecca Scott Bradley

Graduate Theses and Dissertations

The early caregiving environment serves as the context in which young children develop emotional regulation abilities. While supportive, responsive caregiving is crucial for helping children regulate their own emotions in times of stress, disruptions to the parent-child relationship may set the stage for poor emotion regulation throughout childhood. Emotional and behavioral problems, particularly in children with neurodevelopmental conditions, may stem from early difficulties with emotion regulation. If left untreated, emotion dysregulation in children can mark a trajectory towards continued social-emotional concerns and family disruption; as such, the toddler years represent an ideal time for intervention. Parent-Child Interaction Therapy for Toddlers …

Cellulose Membrane Performance And Properties With Focus On Dialysis Application, Juliana Marçal

Graduate Theses and Dissertations

Chronic kidney disease affects approximately 35 million individuals in the United States, with nearly 550,000 patients dependent on dialysis for survival. Chronic kidney disease and end stage kidney disease impose substantial burdens on patients and healthcare systems, driving demand for improved dialysis membranes with enhanced flux, selectivity, and biocompatibility. The performance of dialysis membranes plays a critical role in treatment efficiency, governing solute transport, fluid removal, and overall therapeutic outcomes. In hemodialysis, membranes must achieve an optimal balance between high permeability and selective solute rejection while maintaining mechanical stability and long-term biocompatibility. Conventional dialysis membranes are commonly fabricated from polymeric …
