ASU Electronic Theses and Dissertations


This collection includes most of the ASU Theses and Dissertations from 2011 to present. ASU Theses and Dissertations are available in downloadable PDF format; however, a small percentage of items are under embargo. Information about the dissertations/theses includes degree information, committee members, an abstract, supporting data or media.

In addition to the electronic theses found in the ASU Digital Repository, ASU Theses and Dissertations can be found in the ASU Library Catalog.

Dissertations and Theses granted by Arizona State University are archived and made available through a joint effort of the ASU Graduate College and the ASU Libraries.

The finite supply of current energy production materials has created opportunities for the investigation of alternative energy sources in many fields. One example is the use of microorganisms in bioenergy applications, such as microbial fuel cells. Present in many types of environments, microorganisms with the ability to respire solid electron acceptors have become of increasing relevance to alternative energy and wastewater treatment research. In this dissertation, several aspects of anode respiration are investigated, with the goal of increasing the limited understanding of the mechanisms of electron transport through the use of advanced electrochemical methods. Biofilms of Geobacter sulfurreducens, the model …

Trichloroethene (TCE) is a ubiquitous soil and groundwater contaminant. The most common bioremediation approach for TCE relies on the process of reductive dechlorination by Dehalococcoides mccartyi. D. mccartyi use TCE, dichloroethene, and vinyl chloride as electron acceptors and hydrogen as an electron donor. At contaminated sites, reductive dechlorination is typically promoted by adding a fermentable substrate, which is broken down to short chain fatty acids, simple alcohols, and hydrogen. This study explored microbial chain elongation (MCE), instead of fermentation, to promote TCE reductive dechlorination. In MCE, microbes use simple substrates (e.g., acetate, ethanol) to build medium chain fatty acids and …

Students may be situated within complex systems that are nested within each other. This complexity may also envelope institutional structures that lead to the socio-economic reification of student post-secondary opportunities by obscuring positive goals. This may be confounded by community misunderstandings about the changed world that students are entering. These changes include social and economic factors that impact personal and economic freedoms, our ability to live at peace, and the continuing trend of students graduating high school underprepared. Building on previous cycles of action research, this multi-strand mixed-methods study examined the effects of the innovation of the I am College …

The overall goal of this research project was to assess the feasibility of investigating the effects of microgravity on mineralization systems in unit gravity environments. If possible to perform these studies in unit gravity earth environments, such as earth, such systems can offer markedly less costly and more concerted research efforts to study these vitally important systems. Expected outcomes from easily accessible test environments and more tractable studies include the development of more advanced and adaptive material systems, including biological systems, particularly as humans ponder human exploration in deep space. The specific focus of the research was the design and …

Historically, colonizers, immigrants, and enslaved Africans served as carriers of Islamic culture to Puerto Rico, and today, that Islamic element is often unassumingly intertwined with the Puerto Rican culture. Using Bourdieu's concept of habitus as the framework, this dissertation engages customs and mannerisms of Puerto Ricans to reveal the imprint and legacy of Muslim Spain and the Islamic heritage of West Africa in Puerto Rico. It makes a study of the Spanish language to include vocabulary, proverbs, songs, and games that carry vestiges of Arabic language and culture. Most importantly, it also addresses an inherited religious and cultural tradition rooted …

This dissertation theorizes Bad Faith Rhetorics, or, rhetorical gestures that work to derail, block, or otherwise stymy knowledge-building efforts. This work explores the ways that interventions against existing social hierarchies (i.e., feminist and antiracist interventions) build knowledge (that is, are epistemologically active), and the ways that bad faith rhetorics derail such interventions. This dissertation demonstrates how bad faith rhetorics function to defend the status quo, with its social stratification by race, gender, class, and other intersectional axes of identity. Bad faith argumentative maneuvers are abundant in online environments. Consequently, this dissertation offers two case studies of the comment sections of …

Situated within seminal debates on the questions of liberation and justice viewed from the postcolonial context, this dissertation evaluates freedom narratives from both sides of the colonial divide during the period of high imperialism. Creating a transnational grouping of three diverse historical figures, E. M. Forster, M. K. Gandhi, and James Joyce, I argue for similarities in these writers’ narrative construction of “freedom” against colonial modernity. I argue that despite these writers’ widely disparate historical and cultural determinations, which uniquely particularize each of their freedom formulas as well as freedom “ideals” – the ideal of culture for Forster, renunciation for …

According to the World Health Organization, cancer is one of the leading causes of death around the world. Although early diagnostics using biomarkers and improved treatments with targeted therapy have reduced the rate of cancer related mortalities, there remain many unknowns regarding the contributions of the tumor microenvironment to cancer progression and therapeutic resistance. The tumor microenvironment plays a significant role by manipulating the progression of cancer cells through biochemical and biophysical signals from the surrounding stromal cells along with the extracellular matrix. As such, there is a critical need to understand how the tumor microenvironment influences the molecular mechanisms …

Personal histories are deeply rooted into my way of existence, far before my brain became ready to challenge such notions. While Americans have been witnesses to the splintering effects of colonialism and patriarchy on socialization, I ask two questions: (1) Where to stand within a society that promotes the marginalization of both women and brown bodies? And (2) how to combat these harsh realities and protect those most affected? Being both Black and woman, I decided to embark upon a quest of self-actualization in this document. “Ain’t She Sweet: A Critical Choreographic Study of Identity & Intersectionality,” tracks the creative …

The aim of this research study is to develop a passive architectural design morphology, tuned to the Sonoran Desert, which redefines Desert Modernism and integrates: (a) mitigation of heat transfer through the exterior envelope, and (b) use of daylight to inform appropriate architectural massing. The research investigation was delimited to mid-nineteenth century European modernist examples, and ends with mid-twentieth century modern architecture in the southwestern United States as viewed through the lens of environmental design. The specific focus was on Desert Modernism, a quasi-architectural movement, which purportedly had its beginnings in 1923 with the Coachella Valley, Popinoe Desert Cabin. A …
