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.

The mobile crowdsensing (MCS) applications leverage the user data to derive useful information by data-driven evaluation of innovative user contexts and gathering of information at a high data rate. Such access to context-rich data can potentially enable computationally intensive crowd-sourcing applications such as tracking a missing person or capturing a highlight video of an event. Using snippets and pictures captured from multiple mobile phone cameras with specific contexts can improve the data acquired in such applications. These MCS applications require efficient processing and analysis to generate results in real time. A human user, mobile device and their interactions cause a …

The present study aimed to advance the current understanding of the relation between disability and subjective well-being by examining the extent to which different facets of subjective well-being (life satisfaction, positive affect, and negative affect) change before and after disability onset, and the extent to which age and type of disability moderate such changes. Multiphase growth-curve models to prospective longitudinal survey data from Waves 1-16 of the Household, Income and Labour Dynamics in Australia (HILDA) survey (N = 3,795; mean age = 50.22; age range: 16-99; 51% women). On average, life satisfaction remained relatively stable across the disability transition, whereas …

An evolving understanding of elastomeric polymer nanocomposites continues to expand commercial, defense, and industrial products and applications. This work explores the thermomechanical properties of elastomeric nanocomposites prepared from bisphenol A diglycidyl ether (BADGE) and three amine-terminated poly(propylene oxides) (Jeffamines). The Jeffamines investigated include difunctional crosslinkers with molecular weights of 2,000 and 4,000 g/mol and a trifunctional crosslinker with a molecular weight of 3,000 g/mol. Additionally, carbon nanotubes (CNTs) were added, up to 1.25 wt%, to each thermoset. The findings indicate that the Tg and storage modulus of the polymer nanocomposites can be controlled independently within narrow concentration windows, and that …

The traditional access control system suffers from the problem of separation of data ownership and management. It poses data security issues in application scenarios such as cloud computing and blockchain where the data owners either do not trust the data storage provider or even do not know who would have access to their data once they are appended to the chain. In these scenarios, the data owner actually loses control of the data once they are uploaded to the outside storage. Encryption-before-uploading is the way to solve this issue, however traditional encryption schemes such as AES, RSA, ECC, bring about …

Over a million children who attend American public schools experience homelessness every year. This study investigates the musical lives of children experiencing homelessness through the lens of the ecological systems theory (Bronfenbrenner, 1979). Children encounter music in a variety of ways and develop their own lexicon of meaning that depicts the relationships they have in, through, and around music. Relationship connections in this study were depicted through a system of relationship networks (Neal & Neal, 2013). In this study I present and analyze the cases of nine participants who attended an after-school care program at a homeless shelter for families …

Anti-trafficking research recognizes several populations affected by Commercial Sexual Exploitation (CSE) in the United States (U.S.), yet it has not yet recognized long-term survivors, whose experiences of CSE occurred from the 1960s through the 2000s. Rendering long-term survivors invisible erases the history of CSE in the U.S. and prevents an accurate assessment of the true scope of CSE that it extends from infancy through adulthood. The most grievous CSE cultures target both boys and girls beginning at infancy and extending through early childhood. This project provides a foundation for understanding who long-term survivors are, the types of CSE they experienced, …

This dissertation explores the nature of collaborative writing in an interdisciplinary research context beyond classrooms. Most of the current studies in collaborative writing in second language contexts are based on collaborative writing in classroom-based contexts such as English as a Second Language courses with undergraduate students. Collaborative writing tasks are getting its popularity both in classrooms and beyond classrooms with various purposes and objectives. Thus, it is more likely that multilingual writers encounter some kinds of collaborative writing tasks in various contexts. For writing instructors and writing curriculum developers, it is important to understand various types of collaborative writing tasks …

As the designer is asked to design, create, or simply solve a problem, many factors go into that process. It generally begins with defining the scope or problem that undergoes an iterative process utilizing different tools and techniques to generate the desired outcome. This is often referred to as the design process. Notwithstanding the many factors that influence this process, this study investigates the use of theory for behavior change and its effect on the design process. While social behavioral theories have been extensively discussed in the realm of design, and a well-developed body of literature exists, there is limited …

The marked increase in the inflow of remotely sensed data from satellites have trans- formed the Earth and Space Sciences to a data rich domain creating a rich repository for domain experts to analyze. These observations shed light on a diverse array of disciplines ranging from monitoring Earth system components to planetary explo- ration by highlighting the expected trend and patterns in the data. However, the complexity of these patterns from local to global scales, coupled with the volume of this ever-growing repository necessitates advanced techniques to sequentially process the datasets to determine the underlying trends. Such techniques essentially model …

Component simulation models, such as agent-based models, may depend on spatial data associated with geographic locations. Composition of such models can be achieved using a Geographic Knowledge Interchange Broker (GeoKIB) enabled with spatial-temporal data transformation functions, each of which is responsible for a set of interactions between two independent models. The use of autonomous interaction models allows model composition without alteration of the composed component models. An interaction model must handle differences in the spatial resolutions between models, in addition to differences in their temporal input/output data types and resolutions. A generalized GeoKIB was designed that regulates unidirectional spatially-based interactions …
