This dissertation uses constructivist pedagogy to teach acting via Practical Aesthetics, a system of actor training created in the mid/&ndash1980s; by David Mamet and his college acting students. Primarily taught at the Atlantic Theatre Acting School in New York City, Practical Aesthetics has been the focus of little academic research. The same lack of research regarding constructivist pedagogy exists in academic theatre scholarship. The author takes a step toward rectifying this situation. Using an action research methodology, based on approximately thirteen years of teaching experience, the author suggests that Practical Aesthetics and his accompanying voice and movement exercises can be …

Though the concept of 'transgender' has gained a foothold in American culture, the representation of transgender subjects is both limited and limiting. Media representations of trans experiences generally exclude or negatively depict both trans-masculine people and trans individuals of color. Subsequently, many trans-masculine individuals of color — especially black transmen — turn to online forums to create original content, express what being transgender means to them, and explore topics excluded from mainstream conversations. Utilizing participatory ethnography influenced by digital and visual approaches, “Tumblr Saved My Life”: An Interdisciplinary Investigation of how Black Trans- Masculinity Operates through Tumblr explores how black …

Visual processing in social media platforms is a key step in gathering and understanding information in the era of Internet and big data. Online data is rich in content, but its processing faces many challenges including: varying scales for objects of interest, unreliable and/or missing labels, the inadequacy of single modal data and difficulty in analyzing high dimensional data. Towards facilitating the processing and understanding of online data, this dissertation primarily focuses on three challenges that I feel are of great practical importance: handling scale differences in computer vision tasks, such as facial component detection and face retrieval, developing efficient …

This research conceptualizes Gothic literature featuring undead characters produced and popularized by Britain in the early nineteenth century as educational texts. As an influx of new ideas at home and abroad disrupted the lives of the Romantics, not to mention the literal uprising of bodies in the French Revolution and the lost war with the North American colonies, British citizens dedicated themselves to preserving the relative safety of their shores from external and internal threats. I expand the definition of the “undead” to include any tangible, corporeal being once technically dead and now reanimated. In doing so, I invite a …

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 …

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 …

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.

Bio-modification of asphalt binder brings significant benefits in terms of increasing sustainable and environmental practices, stabilizing prices, and decreasing costs. However, bio-modified asphalt binders have shown varying performance regarding susceptibility to moisture damage; some bio-oil modifiers significantly increase asphalt binder's susceptibility to moisture damage. This variability in performance is largely due to the large number of bio-masses available for use as sources of bio-oil, as well as the type of processing procedure followed in converting the bio-mass into a bio-oil for modifying asphalt binder. Therefore, there is a need for a method of properly evaluating the potential impact of a …
