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 inspiration to undertake this pilot study came after observation and reflection by the clinician-researcher, a board-certified music therapist who has used the harp as the primary instrument when facilitating sessions, on hundreds of music therapy sessions that took place at a facility for behavioral health and chemical dependency. It was observed that the use of improvised harp music as a therapeutic intervention within the context of a music therapy session seemed to relax patients who reported that they were nervous or anxious, and it was also noted that following a listening exercise that consisted of improvised harp music, patients …

Industry, academia, and government have spent tremendous amounts of money over several decades trying to improve the mathematical abilities of students. They have hoped that improvements in students' abilities will have an impact on adults' mathematical abilities in an increasingly technology-based workplace. This study was conducted to begin checking for these impacts. It examined how nine adults in their workplace solved problems that purportedly entailed proportional reasoning and supporting rational number concepts (cognates). The research focused on four questions: a) in what ways do workers encounter and utilize the cognates while on the job; b) do workers engage cognate problems …

There is a lack of music therapy services for college students who have problems with depression and/or anxiety. Even among universities and colleges that offer music therapy degrees, there are no known programs offering music therapy to the institution's students. Female college students are particularly vulnerable to depression and anxiety symptoms compared to their male counterparts. Many students who experience mental health problems do not receive treatment, because of lack of knowledge, lack of services, or refusal of treatment. Music therapy is proposed as a reliable and valid complement or even an alternative to traditional counseling and pharmacotherapy because of …

It is widely documented and accepted that athletes have difficulty maintaining adequate hydration status and that dehydration is a key risk factor for the heat-related illnesses commonly observed among athletes. Research has also suggested that hydration status can influence cognitive performance. Educational interventions focused on rehydration strategies have had minimal success reducing dehydration rates; hence, alternative interventions promoting adequate hydration status in athletes should be explored. This trial examined the efficacy of a commercial hydration mobile application (app) for reducing dehydration rates in campus athletes. Fifty-eight college students aged 18-40 y, who participated in club-level collegiate athletics were recruited from …

Impact cratering has played a crucial role in the surface development of the inner planets. Constraining the timing of this bombardment history is important in understanding the origins of life and our planet's evolution. Plate tectonics, active volcanism, and vegetation hinder the preservation and identification of existing impact craters on Earth. Providing age constraints on these elusive structures will provide a deeper understanding of our planet's development. To do this, (U-Th)/He thermochronology and in situ 40Ar/39Ar laser microprobe geochronology are used to provide ages for the Haughton and Mistastin Lake impact structures, both located in northern Canada. While terrestrial impact …

Silicon Carbide (SiC) junction field effect transistors (JFETs) are ideal for switching high current, high voltage loads in high temperature environments. These devices require external drive circuits to generate pulse width modulated (PWM) signals switching from 0V to approximately 10V. Advanced CMOS microcontrollers are ideal for generating the PWM signals but are limited in output voltage due to their low breakdown voltage within the CMOS drive circuits. As a result, an intermediate buffer stage is required between the CMOS circuitry and the JFET. In this thesis, a discrete silicon-on-insulator (SOI) metal semiconductor field effect transistor (MESFET) was used to drive …

Traditional usability methods in Human-Computer Interaction (HCI) have been extensively used to understand the usability of products. Measurements of user experience (UX) in traditional HCI studies mostly rely on task performance and observable user interactions with the product or services, such as usability tests, contextual inquiry, and subjective self-report data, including questionnaires, interviews, and usability tests. However, these studies fail to directly reflect a user’s psychological involvement and further fail to explain the cognitive processing and the related emotional arousal. Thus, capturing how users think and feel when they are using a product remains a vital challenge of user experience …

Victorian London was often confronted with the filth and waste that was the result of urban civilization. The Victorians saw themselves as a race of humanity above the savage tribes. While steps were taken to repress these natural and instinctual products of humanity, human waste and filth were powerfully incorporated in the fictional writings of Charles Dickens and George Gissing. I argue that this incorporation of filth and waste in both OUR MUTUAL FRIEND and THE NETHER WORLD serves as a metaphorical statement on the living conditions of the Victorian lower class. Using the urban travelogues of Dickens and Gissing's …

Possible selves researchers have uncovered many issues associated with the current possible selves measures. For instance, one of the most famous possible selves measures, Oyserman (2004)'s open-ended possible selves, has proven to be difficult to score reliably and also involves laborious scoring procedures. Therefore, this study was initiated to develop a close-ended measure, called the Persistent Academic Possible Selves Scale for Adolescents (PAPSS), that meets these challenges. The PAPSS integrates possible selves theories (personal and social identities) and educational psychology (self-regulation in social cognitive theory). Four hundred and ninety five junior high and high school students participated in the validation …

The quality and quantity of talented members of the US STEM workforce has been a subject of great interest to policy and decision makers for the past 40 years. Recent research indicates that while there exist specific shortages in specific disciplines and areas of expertise in the private sector and the federal government, there is no noticeable shortage in any STEM academic discipline, but rather a surplus of PhDs vying for increasingly scarce tenure track positions. Despite the seeming availability of industry and private sector jobs, recent PhDs still struggle to find employment in those areas. I argue that the …
