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.

This study investigated the effect of environmental heat stress on physiological and performance measures during a ~4 mi time trial (TT) mountain hike in the Phoenix metropolitan area. Participants (n = 12; 7M/5F; age 21.6 ± 2.47 [SD]) climbed ‘A’ mountain (~1 mi) four times on a hot day (HOT; wet bulb globe temperature [WBGT] = 31.6°C) and again on a moderate day (MOD; WBGT = 19.0°C). Physiological and performance measures were made before and throughout the course of each hike. Mean pre-hike hydration status (urine specific gravity [USG]) indicated that participants began both HOT and MOD trials in a euhydrated state (1.016 ± 0.010 and 1.010 ± 0.008, respectively) and means did not differ significantly between trials (p = .085). Time trial performance was impaired by -11% (11.1 minutes) in the HOT trial (105 ± 21.7 min), compared to MOD (93.9 ± 13.1 min) (p = .013). Peak core temperatures were significantly higher in HOT (38.5 ± 0.36°C) versus MOD (38.0 ± 0.30°C) with progressively increasing differences between trials over time (p < .001). Peak ratings of perceived exertion were significantly higher in HOT (14.2 ± 2.38) compared to MOD (11.9 ± 2.02) (p = .007). Relative intensity (percent of age-predicted maximal heart rate [HR]), estimated absolute intensity (metabolic equivalents [METs]), and estimated energy expenditure (MET-h) were all increased in HOT, but not significantly so. The HOT condition reduced predicted maximal aerobic capacity (CRFp) by 6% (p = .026). Sweat rates differed significantly between HOT (1.38 ± 0.53 L/h) and MOD (0.84 ± 0.27 L/h) (p = .01). Percent body mass loss (PBML) did not differ significantly between HOT (1.06 ± 0.95%) and MOD (0.98 ± 0.84%) (p = .869). All repeated measures variables showed significant between-subjects effects (p < .05), indicating individual differences in response to test conditions. Heat stress was shown to negatively affect physiological and performance measures in recreational mountain hikers. However, considerable variation exists between individuals, and the degree of physiological and performance impairment is probably due, in part, to differences in aerobic fitness and acclimatization status rather than pre- or during-performance hydration status.
In this study, I analyze the construction of childhood and nature in a number of Korean Theatre For Young Audience (TFY) works and family movies produced since 2000. Studying The Tale of Haruk, Gamoonjang Baby, Oseam and The Way Home, I explore the childhood memes that surface in the analysis and how they relate to dominant cultural understandings of Korean childhood. Both nature and childhood are metaphorical spaces reflecting the specificity of the cultural context in which they are situated. And in the works I explore, the two are paired in interesting and complex ways and for ideological reasons, the study of which produces a deeper understanding of the construction of Korean childhood. The “child" in Korean TFY has not been thoroughly explored in earlier scholarly work, nor do many preceding studies explore the performance texts of Korean TFY from an analytic stance. This is a serious gap in the literature, considering the significance of the discourse on childhood as a major conceptual framework bolstering TFY and the centrality of the performative aspect of the field. Thus, this study is meaningful as one of the first doctoral works to analyze the performance texts of Korean TFY and the first work to explore Korean TFY from a childhood studies framework. The findings of this interdisciplinary work will be of interest to the field of childhood studies and TFY, broadly defined. In studying the works, my main methodology has been detailed performance analysis. Through the analysis, interesting tropes of Korean childhood emerge, some of which have not been addressed explicitly before. My work reveals Korean childhood as a hybrid cultural assemblage reflecting the complexity of the Korean cultural context, where historical, current, native and foreign ideas about childhood mingle.
This project examines a cross training style of studying transcriptions for the advancing tubist. Similar to how athletes cross train in two or more sports to improve their abilities, the tubist may cross train with transcriptions in order to improve the technical and musical skills required in modern tuba literature. Transcribed materials will be used to develop facility in the areas of technique, phrasing, and stylistic interpretation using three unique pieces of standard solo tuba repertoire; Krzysztof Penderecki’s Capriccio, the John Williams Tuba Concerto, and Anthony Plog’s Three Miniatures.
