ASU Electronic Dissertations and Theses

The ASU Libraries provides access to the full text of most ASU’s Dissertations and Theses, from 2011 to the present. In most cases, ASU Dissertations and Theses are available in downloadable PDF format. However, a small percentage of items are under embargo. Information about the dissertation/thesis includes degree information, committee members, an abstract by the author, and submitted supporting data and media.

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

Description: This study's purpose was to explore effectiveness of alternate format in-service delivery for what teachers needed to know to effectively teach their students with Autism Spectrum Disorder/High Functioning Autism/Asperger Syndrome (ASD/HFA/AS) in the general education setting. The study's research questions included: Did participants learn information they needed as well using asynchronous online in-service format models as when in a traditional face-to-face consultative approach? Did the use of a broad asynchronous online discussion approach to collaboration result in effective student problem-solving for the participants? Did participant attitudes change toward online instruction as a means of collaboration as a result of engaging ...

Description: The metalloenzyme quercetin 2,3-dioxygenase (QueD) catalyzes the oxidative decomposition of the aromatic compound, quercetin. The most recently characterized example is a product of the bacterium Bacillus subtilis (BsQueD); all previous examples were fungal enzymes from the genus Aspergillus (AQueD). AQueD contains a single atom of Cu(II) per monomer. However, BsQueD, over expressed in Escherichia coli, contains Mn(II) and has two metal-binding sites, and therefore two possible active sites per monomer. To understand the contribution of each site to BsQueD's activity, the N-terminal and C-terminal metal-binding sites have been mutated individually in an effort to disrupt metal binding. In wild type ...

Description: ABSTRACT This thesis analyzes the discourse surrounding proposed solutions to the immigration phenomenon in the United States. I conducted two qualitative media analyses on the rhetoric and conceptual frames found in mass media newscasts reporting on the immigration debate. The first analysis covered the general immigration debate and the second covered the appearance of American southwest ranchers. Specifically the analyses contrasted the media's coverage of root economic causes to the immigration phenomenon in comparison to reactionary solutions as proposed by leading immigrant attrition organizations such as the immigration think tank, Federation for American Immigration Reform (FAIR) and Republican linguist, Frank ...

Description: In the traditional setting of quantum mechanics, the Hamiltonian operator does not depend on time. While some Schrödinger equations with time-dependent Hamiltonians have been solved, explicitly solvable cases are typically scarce. This thesis is a collection of papers in which this first author along with Suslov, Suazo, and Lopez, has worked on solving a series of Schrödinger equations with a time-dependent quadratic Hamiltonian that has applications in problems of quantum electrodynamics, lasers, quantum devices such as quantum dots, and external varying fields. In particular the author discusses a new completely integrable case of the time-dependent Schrödinger equation in R^n with ...

Description: Today, many wireless networks are single-channel systems. However, as the interest in wireless services increases, the contention by nodes to occupy the medium is more intense and interference worsens. One direction with the potential to increase system throughput is multi-channel systems. Multi-channel systems have been shown to reduce collisions and increase concurrency thus producing better bandwidth usage. However, the well-known hidden- and exposed-terminal problems inherited from single-channel systems remain, and a new channel selection problem is introduced. In this dissertation, Multi-channel medium access control (MAC) protocols are proposed for mobile ad hoc networks (MANETs) for nodes equipped with a single ...

Description: The American Psychiatric Association's Diagnostic and Statistical Manual, the official guidebook to psychiatric diagnosis in America, currently exempts the recently bereaved from being diagnosed with depression unless their experiences are marked by feelings of extreme worthlessness, significant functional impairment, psychotic symptoms, psychomotor retardation, or suicidal ideation. Ordinary symptoms of depression, such as sleeplessness or loss of appetite, are considered healthy, functional emotional responses to the loss of a loved one. The bereavement exemption is slated for removal in the upcoming fifth edition of the Diagnostic and Statistical Manual, functionally redefining the emotional distress of bereavement as a psychiatric disorder. This ...

Description: In recent years, the world has debated the idea of biofuels as a solution to energy security, energy independence, and global climate change. However, as the biofuels movement has unfolded, crucial issues emerged regarding biofuels efficacy and efficiency. The deployment of biofuels of marginal benefit has raised questions about how countries like the USA may have found themselves so invested in a potentially failing technology. In order to better understand and evaluate these issues, this study utilizes the Ostrom Institutional Analysis and Development (IAD) framework to better evaluate these issues and analyze interacting institutions that shape US biofuel policy. The ...

Description: This study examined the quality of professional life at a Title I school that has achieved the Arizona Department of Education's highest accountability rating of Excelling for eight consecutive years. By examining the factors that influence the school environment including teachers' attitudes and the connections within the teacher community at this school, a description emerged of the factors that influenced the quality of professional lives of teachers. This descriptive study sought to describe, "What is the quality of professional life for teachers at a Title I elementary school with a history of high levels of student achievement?" The research was ...

Description: Concerns about Peak Oil, political instability in the Middle East, health hazards, and greenhouse gas emissions of fossil fuels have stimulated interests in alternative fuels such as biofuels, natural gas, electricity, and hydrogen. Alternative fuels are expected to play an important role in a transition to a sustainable transportation system. One of the major barriers to the success of alternative-fuel vehicles (AFV) is the lack of infrastructure for producing, distributing, and delivering alternative fuels. Efficient methods that locate alternative-fuel refueling stations are essential in accelerating the advent of a new energy economy. The objectives of this research are to develop ...

Description: Media is a powerful tool used to reflect and affect change in society. Within this study, a brief historical context is provided of roles African Americans in film were traditionally cast in. By employing Critical Race Theory (CRT), cultural capital, and NewBlackMan frameworks, I analyzed how Black male film directors and producers depicted race, class, gender within the Black film boom of the early 2000s. I examined the depictions of educational outcomes of the characters within films utilized in this study. My results display progress that still needs to be made in breaking down traditional gender roles, how race needed ...
