The intracellular motility seen in the cytoplasm of angiosperm plant pollen tubes is known as reverse fountain cytoplasmic streaming (i.e., cyclosis). This effect occurs when organelles move anterograde along the cortex of the cell and retrograde down the center of the cell. The result is a displacement of cytoplasmic volume causing a cyclic motion of organelles and bulk liquid. Visually, the organelles appear to be traveling in a backwards fountain hence the name. The use of light microscopy bioimaging in this study has documented reverse fountain cytoplasmic streaming for the first time in fungal hyphae of Rhizopus oryzae and other …

ABSTRACT This dissertation examines the role of tribal sovereignty and self-determination in research for Diné participants and elders from 1956-1986. The qualitative historical research study explored the following questions: How has past research been conducted on the Navajo Nation? What is the role of sovereignty and self-determination in research and research methodology for Diné peoples? And, how might Diné philosophy inform a research methodology that aligns with cultural protocols and practices? Six elders who participated in research from 1956-1986 participated in in-depth interviews about their experiences. Using Sa’ąh Naaghái Bik’eh Hozhǫ̨̨́ǫ́n and related Diné philosophy models, findings of this study …

The human ankle is a vital joint in the lower limb of the human body. As the point of interaction between the human neuromuscular system and the physical world, the ankle plays important role in lower extremity functions including postural balance and locomotion . Accurate characterization of ankle mechanics in lower extremity function is essential not just to advance the design and control of robots physically interacting with the human lower extremities but also in rehabilitation of humans suffering from neurodegenerative disorders. In order to characterize the ankle mechanics and understand the underlying mechanisms that influence the neuromuscular properties of …

Satellite cells are adult muscle stem cells that activate, proliferate, and differentiate into myofibers upon muscle damage. Satellite cells can be cultured and manipulated in vitro, and thus represent an accessible model for studying skeletal muscle biology, and a potential source of autologous stem cells for regenerative medicine. This work summarizes efforts to further understanding of satellite cell biology, using novel model organisms, bioengineering, and molecular and cellular approaches. Lizards are evolutionarily the closest vertebrates to humans that regenerate entire appendages. An analysis of lizard myoprogenitor cell transcriptome determined they were most transcriptionally similar to mammalian satellite cells. Further examination …

Adoptive transfer of T cells engineered to express synthetic antigen-specific T cell receptors (TCRs) has provocative therapeutic applications for treating cancer. However, expressing these synthetic TCRs in a CD4+ T cell line is a challenge. The CD4+ Jurkat T cell line expresses endogenous TCRs that compete for space, accessory proteins, and proliferative signaling, and there is the potential for mixed dimer formation between the α and β chains of the endogenous receptor and that of the synthetic cancer-specific TCRs. To prevent hybridization between the receptors and to ensure the binding affinity measured with flow cytometry analysis is between the tetramer …

Blalock’s (1967) minority threat perspective is one of the most empirically investigated theories of crime control in criminological literature. A large body of research has tested this perspective and established a link between minority context and increased criminal justice controls. The perceived threat mechanisms hypothesized to facilitate this link, however, have received relatively scant attention. In addition, no multidimensional scale of perceived minority threat has been developed. These oversights have significantly impeded the advancement of research testing the empirical validity and generalizability of Blalock’s premises across racial and ethnic groups. Against this backdrop, this dissertation extends prior work by conducting …

Extended crystal defects often play a critical role in determining semiconductor device performance. This dissertation describes the application of transmission electron microscopy (TEM) and aberration-corrected scanning TEM (AC-STEM) to study defect clusters and the atomic-scale structure of defects in compound semiconductors. An extensive effort was made to identify specific locations of crystal defects in epitaxial CdTe that might contribute to degraded light-conversion efficiency. Electroluminescence (EL) mapping and the creation of surface etch pits through chemical treatment were combined in attempts to identify specific structural defects for subsequent TEM examination. Observations of these specimens revealed only surface etch pits, without any …

In this dissertation, I examine how social perceptions of physical disability shape interactions in healthcare. Drawing upon the lived experience and insights of Diné (Navajo) individuals with physical disabilities, family members, and Diné/non-indigenous healthcare workers and service providers, I explore the interrelationship of social perceptions of physical disability with understandings of identity and performance of personhood. Embedded within discourses and critiques of ableism/disablism, narratives highlight the interconnection of constructs of personhood and productivity. Findings show that social perceptions of physical disability are closely linked to broader cultural norms surrounding concepts of health/illness. I offer a critical analysis of contemporary impacts …

The small mitogenic cytokine Pleiotrophin (PTN) is well-known for its roles in tissue growth, development, and repair. First isolated from neuronal tissues, much interest in this protein resides in development of the central nervous system and neuronal regeneration. Owning to its role in growth, development and its ability to promote angiogenesis and metastasis, PTN’s overexpression in cancers such as glioblastoma, has become the focal point of much research. Many of the receptors through which PTN acts contain glycosaminoglycans (GAGs), through which PTN binds. Thus, understanding the atomistic detail of PTN’s architecture and interaction with GAG chains is of significant importance …

Special education identification processes related to English language learners (ELs) in the United States have puzzled the field for decades. The phenomenon of referrals, the first step toward identification, is complex since it requires deciphering the root cause of students’ learning struggles—e.g., second language (L2) factors, the possibility of a learning disability (LD), or the combination of multiple other influences. To investigate the various influences contributing to learning difficulties, I centered this study on three potential sources, individual, institutional, and interpersonal. I aimed to answer, how did sociocultural influences mediate a teacher’s understanding of ELs’ competence? How did sociocultural influences …

The Java programing language was implemented in such a way as to limit the amount of possible ways that a program written in Java could be exploited. Unfortunately, all of the protections and safeguards put in place for Java can be circumvented if a program created in Java utilizes internal or external libraries that were created in a separate, insecure language such as C or C++. A secure Java program can then be made insecure and susceptible to even classic vulnerabilities such as stack overflows, string format attacks, and heap overflows and corruption.

Generative Adversarial Networks are designed, in theory, to replicate the distribution of the data they are trained on. With real-world limitations, such as finite network capacity and training set size, they inevitably suffer a yet unavoidable technical failure: mode collapse. GAN-generated data is not nearly as diverse as the real-world data the network is trained on; this work shows that this effect is especially drastic when the training data is highly non-uniform. Specifically, GANs learn to exacerbate the social biases which exist in the training set along sensitive axes such as gender and race. In an age where many datasets …

A mathematical approach was developed to evaluate the resilience of coupled power-water networks using a variant of contingency analysis adapted from electric transmission studies. In particular, the “what if” scenarios explored in power systems research were extended and applied for coupled power-water network research by evaluating how stressors and failures in the water network can propagate across system boundaries and into the electric network. Reduction in power system contingency reserves was the metric for determining violation of N-1 contingency reliability. Geospatial considerations were included using high-resolution, publicly available Geographic Information System data on infrastructure in the Phoenix Metropolitan Area that …

This paper closely examines the performance practice regarding articulation of the preludes from Bach’s Well-Tempered Clavier Book I. Recordings by five pianists are studied: Vladimir Feltsman, Glenn Gould, Angela Hewitt, Andras Schiff, and Rosalyn Tureck. The recordings reveal certain recurring articulation patterns which are categorized into six articulation techniques: short slurs, long slurs, detached upbeat, accented downbeats, changing articulation, and rolled chords. The author has divided the preludes into four groups: preludes with continuous running figuration, lyrical preludes, lyrical preludes with distinct melody and accompaniment, and preludes with non-lyrical themes. Analysis reveals that for each group of preludes, there are …

Empathy is a critical component of high-quality healthcare. When present in the clinical encounter, empathy is important to physicians (empathy is correlated with reductions in physician anxiety and burnout) and to patients (empathy is correlated with better medical decision making, enhanced trust, and improved treatment adherence). Unfortunately, there is an empathy gap in healthcare–physicians often miss opportunities to demonstrate empathy to their patients. This leaves patients feeling unheard, less likely to bring up details important to their care, and less likely to follow treatment guidelines from physicians, thus disrupting the physician-patient relationship.

In the current photovoltaic (PV) industry, the O&M (operations and maintenance) personnel in the field primarily utilize three approaches to identify the underperforming or defective modules in a string: i) EL (electroluminescence) imaging of all the modules in the string; ii) IR (infrared) thermal imaging of all the modules in the string; and, iii) current-voltage (I-V) curve tracing of all the modules in the string. In the first and second approaches, the EL images are used to detect the modules with broken cells, and the IR images are used to detect the modules with hotspot cells, respectively. These two methods …

Prejudice and discrimination toward gender non-conforming individuals is prevalent and extreme in today’s society. This prejudice can manifest in social exclusion, bullying, and victimization, or physical and sexual assault, and can result in negative social, psychological, academic, and physical health outcomes (e.g., depression, anxiety, suicidality). Thus, it is important to understand the perpetrators of gender expression-based aggression and discrimination. In two studies, I addressed how and why people experience prejudice toward gender non-conforming individuals. Using an affordance management theoretical framework, Study 1 identified threats young adults perceived from gender non-conforming peers. There were differences in perceived threats to personal freedoms, …

Coronaviruses are the causative agents of SARS, MERS and the ongoing COVID-19 pandemic. Coronavirus envelope proteins have received increasing attention as drug targets, due to their multiple functional roles during the infection cycle. The murine coronavirus mouse hepatitis virus strain A59, a hepatic and neuronal tropic coronavirus, is considered a prototype of the betacoronaviruses. The envelope protein of the mouse hepatitis virus (MHV-E) was extensively screened with various membrane mimetics by solution state nuclear magnetic resonance spectroscopy to find a suitable mimetic, which allowed for assignment of ~97% of the backbone atoms in the transmembrane region. Following resonance assignments, the …
