Tissue-Engineered Models For Investigating Nerve Infiltration In Fibrotic Microenvironments, Nikolas Ala-Kokko
Tissue-Engineered Models For Investigating Nerve Infiltration In Fibrotic Microenvironments, Nikolas Ala-Kokko
Graduate Theses and Dissertations
Neuron infiltration is involved in a multitude of diseased states and is critical in the regeneration of physiologic conditions. Modeling of innervation in three-dimensional, heterogenous, environments would allow early investigation in the crosstalk of neurons and native cells in normal and pathophysiologic microenvironments to gain an understanding of mechanistic functions. This would allow for greater insight into the role of metabolism, cell adhesion, microenvironmental alternations, cellular crosstalk, and signaling pathways that play a role in the promotion and prevention of neurite growth. In this thesis, with the construction of collagen-based hydrogels as the foundation for cell culture, we investigate cell …
Citizenship And Human Rights: The Path To Reparation, Larissa Rocha
Citizenship And Human Rights: The Path To Reparation, Larissa Rocha

This study builds upon previous consumer perceptions of GMOs studies. A need existed to determine what, if any, effects social media messages about GMOs had on consumer perceptions in Arkansas. The study utilized a qualitative approach with three focus groups. Data were analyzed using descriptive code. Participants were found to have a general understanding of GMOs, though discussion about what a GMO product was took an uncertain tone. Most participants did not consider GMOs as a factor when purchasing products. Rather participants considered characteristics such as price, quality, and convenience. Participants did not believe the infographics had changed their opinions …
Characterization Of Human Fibroblast Growth Factor 2 Variant To Determine Effects On Structure, Stability, And Cell Proliferation, Ryan Layes
Graduate Theses and Dissertations
Fibroblast growth factors (FGFs) are a family of cell signaling proteins conserved across multiple species. Each individual FGF elicits different cellular functions including, but not limited to, proliferation, migration, differentiation, angiogenesis, and wound healing. One of the most studied members, fibroblast growth factor 2 (FGF2), has demonstrated substantial wound healing capacity in a wide range of tissues including skeletal, muscular, neural, respiratory, epithelial, and cardiovascular. This ability makes FGF2 a potential therapeutic for a wide range of conditions and injuries. However, due to a short half-life at room temperature, therapeutic use of FGF2 is limited. It has been demonstrated that …

Density And Occupancy Of Mammals Along An Urban To Rural Gradient In Northwest Arkansas, Leah E. Mctigue
Density And Occupancy Of Mammals Along An Urban To Rural Gradient In Northwest Arkansas, Leah E. Mctigue
Graduate Theses and Dissertations
Human development is a rapidly expanding phenomenon impacting wildlife communities globally. As the human footprint expands, natural greenspace and nature reserves become fragmented and isolated. Wildlife species and communities respond to these changes in different ways. Urban exploiters persist in more urban areas and are able to take advantage of anthropogenic subsidies (food, shelter, etc). Urban avoiders, however, are species that may be pushed out of developed areas or occur in lower densities relative to undisturbed areas. Northwest Arkansas is an optimal location to study the impacts of urbanization on wildlife communities, as the current human population is expected to …

Enhancing Depression Screening And Treatment For Latinxs Residing In The U.S., Linda Esperanza Guzman
Enhancing Depression Screening And Treatment For Latinxs Residing In The U.S., Linda Esperanza Guzman
Graduate Theses and Dissertations
Introduction: In the U.S., Latinxs with Spanish as their preferred language encounter two prominent structural barriers impacting access to treatment for major depressive disorder (MDD). The first is that MDD symptoms commonly go undetected in Latinxs with Spanish compared to English as their preferred language. This might be perhaps because commonly used MDD screeners lack somatic symptom survey items culturally specific in how MDD may present among Latinxs with Spanish as their preferred language. The second structural barrier is that treatment access and completion rates are lower in Spanish-speaking than English-speaking Latinxs, perhaps due to treatments lacking the structure and …

Her Story Told Her Way: A Narrative Inquiry Into Black Women’S Perception Of The Strong Black Woman., Chulyndria Chanee Laye
Graduate Theses and Dissertations
The narrative surrounding the meaning of being a Black woman has historically been dominated by stereotypes such as the mammy, jezebel, sapphire, and angry Black woman. Black women have attempted to control their own narrative through the internalization of these stereotypes, leading to the creation of the Strong Black Woman (SBW) construct. While the SBW is comprised of a sense of caretaker, independence, and emotional restraint, Black women’s attempts at embodying this construct in the face of societal oppression and familial responsibilities can and often does have negative effects on their mental health. Although the behaviors associated with the SBW …

Molecular Characterization Of Compartment Boundary Formation During Epithelial Remodeling In Drosophila Melanogaster, Samia Parveen
Molecular Characterization Of Compartment Boundary Formation During Epithelial Remodeling In Drosophila Melanogaster, Samia Parveen
Graduate Theses and Dissertations
The ability of epithelial cells to self-organize is crucial for the development of proper tissue structures and organs in multi-cellular organisms. Epithelia consist of inter-connected cells that form flat sheets, and specific groups of cells within these sheets are partitioned into distinct compartments via compartment boundaries (CBs). These CBs are specialized interfaces between cells characterized by stable, high-tension actomyosin cables, which act as fences to prevent movements between adjacent compartments during tissue reorganization. In the early Drosophila embryo, CBs are established in response to the asymmetrical localization of two cell-surface proteins the Leucine-Rich Repeat (LRR) protein Tartan and the Teneurin …

Leigh syndrome (LS) is a rare and devastating primary mitochondrial disorder characterized by progressive neuromuscular degeneration. Despite its severe consequences, the clinical genotype pathophysiological underlying LS remains elusive, posing significant challenges for the development of effective therapies. The current study aims to advance our understanding of the pathology and phenotype correlation of LS by evaluating mitochondrial dynamics and bioenergetics in patient-derived human induced pluripotent stem cells (hiPSCs) and their differentiated derivatives, which serve as a reliable model of the disease. Key …
The Hidden Role Of Religiosity In Contemporary Public Education In The United States Of America, Marilyn Anderson Rhames
The Hidden Role Of Religiosity In Contemporary Public Education In The United States Of America, Marilyn Anderson Rhames
Graduate Theses and Dissertations
The ‘separation of church and state’ is a fundamental precept of the United States, yet the phrase itself is not written in the Constitution and even Supreme Court justices disagree on how it should be defined. The ambiguity surrounding religious liberty is perhaps most felt in K-12 public education, where the fear of inflicting faith formation on impressionable students has inspired the vision of a secular, God-neutral, government-run school system. As such, federal and state laws dictate that public school educators who coerce students by promoting or inhibiting religious devotion risk losing their jobs. Yet, the reality is that the …

Differences In Due Process During Post-Conviction: Examining Jurisdictional Influence On Exoneration, Kimberly Hawkins
Graduate Theses and Dissertations
Research on wrongful conviction has found several factors associated with an erroneous conviction. As of yet, research has not delved into the jurisdictional effects on exoneration. Using the American State’s use of the death penalty for a proxy of punitiveness, this study will examine if there is a relationship between use of capital punishment and exoneration rates. The National Registry of Exonerations is the most comprehensive collection of exonerations to date and this secondary data source will be analyzed using logistic regression models to examine differences across policy environments. Result show that non-death penalty states have a much higher exoneration …
Presentation Matters: Effects Of Presentation Order Of Personality Feedback And Need For Structure On Participant Response To Feedback, Alita Marie Mobley Tu
Presentation Matters: Effects Of Presentation Order Of Personality Feedback And Need For Structure On Participant Response To Feedback, Alita Marie Mobley Tu
Graduate Theses and Dissertations
Psychological assessment plays a vital role in differential diagnosis, treatment planning, and measurement of treatment effectiveness. Insufficient or ineffective feedback to the client can limit the utility of psychological assessment. Finn and Tonsager (1997) advise that assessment feedback will be best received when the feedback content is ordered to start with information that is most consistent with the client’s existing self-concept to information that is the most discrepant from their self-concept. There is minimal empirical support for this practice recommendation. The current study investigates the relationship between presentation order of personality feedback and participant response to feedback (i.e., feedback evaluations, …
