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. For more information or questions about this collection contact or visit the Digital Repository ETD Library Guide or contact the ASU Graduate College at gradformat@asu.edu.

Background: The Academy of Nutrition and Dietetics states that it is possible for a vegetarian to obtain the recommended amount of nutrients with a properly planned diet but nutrient deficiencies, such as vitamin B12 deficiency, may occur if diet planning is not optimal. An early indicator of B12 deficiency is raised homocysteine concentrations in blood which can cause health issues. Objective: The amino acid methionine is consumed via dietary protein. Methionine is used in the biosynthesis of other proteins. After a removal of a methyl group, it makes homocysteine. Slightly raised homocysteine may promote greater synthesis of glutathione, an important …

This document is a compendium of the materials that are housed within the special collections donated by Thomas Everett. In August 2016, the Arizona State University School of Music, through the efforts of retired Professor of Trombone Douglas Yeo, received a donation of materials from Thomas Everett, founder of the International Trombone Association and retired director of bands at Harvard University. This donation contains published and unpublished music, numerous letters, and various drafts of his book, An Annotated Guide to Bass Trombone Literature. Over the course of two-and-a-half years, the donation was catalogued for the university by the author. Materials …

This dissertation examines six different models in the field of econophysics using interacting particle systems as the basis of exploration. In each model examined, the underlying structure is a graph G = (V , E ), where each x ∈ V represents an individual who is characterized by the number of coins in her possession at time t. At each time step t, an edge (x, y) ∈ E is chosen at random, resulting in an exchange of coins between individuals x and y according to the rules of the model. Random variables ξt, and ξt(x) keep track of the …

The transition experience for students who are transferring from community college to university can be an overwhelming experience for any typical student, but can be even greater for students with vulnerable backgrounds. This phenomenological action research study followed the five-month community college to the university transition experience of five students in a scholarship program. The students participated in a three-part intervention in support of their transition experience. Three theoretical perspectives framed the study: community cultural wealth, transition theory, and transfer student capital. This framework enabled me to first identify the strengths the students possessed, despite their vulnerable backgrounds, through participation …

In the daily life of an individual problems of varying difficulty are encountered. Each problem may include a different number of constraints placed upon the problem solver. One type of problem commonly used in research are multiply-constrained problems, such as the compound remote associates. Since their development they have been related to creativity and insight. Moreover, research has been conducted to determine the cognitive abilities underlying problem solving abilities. We sought to fully evaluate the range of cognitive abilities (i.e., working memory, episodic and semantic memory, and fluid and crystallized intelligence) linked to multiply-constrained problem solving. Additionally, we sought to …

The large-scale anthropogenic emission of carbon dioxide into the atmosphere leads to many unintended consequences, from rising sea levels to ocean acidification. While a clean energy infrastructure is growing, mid-term strategies that are compatible with the current infrastructure should be developed. Carbon capture and storage in fossil-fuel power plants is one way to avoid our current gigaton-scale emission of carbon dioxide into the atmosphere. However, for this to be possible, separation techniques are necessary to remove the nitrogen from air before combustion or from the flue gas after combustion. Metal-organic frameworks (MOFs) are a relatively new class of porous material …

Gallium Nitride (GaN) based Current Aperture Vertical Electron Transistors (CAVETs) present many appealing qualities for applications in high power, high frequency devices. The wide bandgap, high carrier velocity of GaN make it ideal for withstanding high electric fields and supporting large currents. The vertical topology of the CAVET allows for more efficient die area utilization, breakdown scaling with the height of the device, and burying high electric fields in the bulk where they will not charge interface states that can lead to current collapse at higher frequency. Though GaN CAVETs are promising new devices, they are expensive to develop due …

Due to the growing popularity of the Internet and smart mobile devices, massive data has been produced every day, particularly, more and more users’ online behavior and activities have been digitalized. Making a better usage of the massive data and a better understanding of the user behavior become at the very heart of industrial firms as well as the academia. However, due to the large size and unstructured format of user behavioral data, as well as the heterogeneous nature of individuals, it leveled up the difficulty to identify the SPECIFIC behavior that researchers are looking at, HOW to distinguish, and …

This mixed methods study explores the work of five small writing communities formed within a university-based preservice English language arts writing methods course. Fifteen preservice English language arts teachers took part in the study and participated across five peer writing groups. The study shares the instructional design of the course as well as the writing activities and practices that took place within the groups over the course of one 15-week semester. The study draws on Wenger’s (1998, 2009) theory of communities of practice as well as activity theory (Engeström,1999, 2001; Russell, 1997) to understand the social supports, practices, and learning …

Cultural background is very important for people, and people from different cultural backgrounds will have different understandings of art. This document explores how individuals relate to other cultures and incorporate the advantages of Chinese cultural values into contemporary dance experiences as researched for the applied project, III. This project uses the Bagua theory in the ancient Chinese book the I Ching to carry out the process of collaborative creation through different art forms in collaboration with artists from different mediums. This document details the artist’s process of self-exploration and creative expansion using personal cultural background and influences (both Eastern and …
