Description
Achievement of many long-term goals requires sustained practice over long durations. Examples include goals related to areas of high personal and societal benefit, such as physical fitness, which requires a practice of frequent exercise; self-education, which requires a practice of frequent study; or personal productivity, which requires a practice of performing work. Maintaining these practices can be difficult, because even though obvious benefits come with achieving these goals, an individual's willpower may not always be sufficient to sustain the required effort. This dissertation advocates addressing this problem by designing novel interfaces that provide people with new practices that are fun and enjoyable, thereby reducing the need for users to draw upon willpower when pursuing these long-term goals. To draw volitional usage, these practice-oriented interfaces can integrate key characteristics of existing activities, such as music-making and other hobbies, that are already known to draw voluntary participation over long durations. This dissertation makes several key contributions to provide designers with the necessary tools to create practice-oriented interfaces. First, it consolidates and synthesizes key ideas from fields such as activity theory, self-determination theory, HCI design, and serious leisure. It also provides a new conceptual framework consisting of heuristics for designing systems that draw new users, plus heuristics for making systems that will continue drawing usage from existing users over time. These heuristics serve as a collection of useful ideas to consider when analyzing or designing systems, and this dissertation postulates that if designers build these characteristics into their products, the resulting systems will draw more volitional usage. To demonstrate the framework's usefulness as an analytical tool, it is applied as a set of analytical lenses upon three previously-existing experiential media systems. To demonstrate its usefulness as a design tool, the framework is used as a guide in the development of an experiential media system called pdMusic. This system is installed at public events for user studies, and the study results provide qualitative support for many framework heuristics. Lastly, this dissertation makes recommendations to scholars and designers on potential future ways to examine the topic of volitional usage.

Description
Coccidioidomycosis, also known as Valley Fever, is a disease caused by the dimorphic soil-dwelling fungus, Coccidioides sp. Coccidioidomycosis is difficult to diagnose because symptoms are similar to community-acquired pneumonia. Current diagnostic tests rely on antibody responses, but immune responses can be delayed and aberrant, resulting in false negative diagnoses. Unlike serology, detection of coccidioidal proteins or other fungal components in blood could distinguish valley fever from other pulmonary infections and provide a definitive diagnosis. Using mass spectrometry (LC-MS/MS) we examined the plasma peptidome from patients with serologically confirmed coccidioidomycosis. Mass spectra were searched using the protein database from the Coccidioides species, generated and annotated by the Broad Institute. 15 of 20 patients with serologically confirmed coccidioidomycosis demonstrated the presence of a peptide in plasma, "PGLDSKSLACTFSQV" (PGLD). The peptide is derived from an open reading frame from a "conserved hypothetical protein" annotated with 2 exons, and to date, found only in the C. posadasii strain Silviera RMSCC 3488 genomic sequence. In this thesis work, cDNA sequence analysis from polyadenylated RNA confirms the peptide sequence and genomic location of the peptide, but does not indicate that the intron in the gene prediction of C. posadasii strain Silviera RMSCC 3488 is present. A monoclonal antibody generated against the peptide bound to a 16kDa protein in T27K coccidioidal lysate. Detecting components of the fungus plasma could be a useful diagnostic tool, especially when serology does not provide a definitive diagnosis.

Description
In the 1930s, with the rise of Nazism, many artists in Europe had to flee their homelands and sought refuge in the United States. Austrian composer Hanns Eisler who had risen to prominence as a significant composer during the Weimar era was among them. A Jew, an ardent Marxist and composer devoted to musical modernism, he had established himself as a writer of film music and Kampflieder, fighting songs, for the European workers' movement. After two visits of the United States in the mid-1930s, Eisler settled in America where he spent a decade (1938-1948), composed a considerable number of musical works, including important film scores, instrumental music and songs, and, in collaboration with Theodor W. Adorno, penned the influential treatise Composing for the Films. Yet despite his substantial contributions to American culture American scholarship on Eisler has remained sparse, perhaps due to his reputation as the "Karl Marx in Music." In this study I examine Eisler's American exile and argue that Eisler, through his roles as a musician and a teacher, actively sought to enrich American culture. I will present background for his exile years, a detailed overview of his American career as well as analyses and close readings of several of his American works, including three of his American film scores, Pete Roleum and His Cousins (1939), Hangmen Also Die (1943), and None But the Lonely Heart (1944), and the String Quartet (1940), Third Piano Sonata (1943), Woodbury Liederbüchlein (1941), and Hollywood Songbook (1942-7). This thesis builds upon unpublished correspondence and documents available only in special collections at the University of Southern California (USC), as well as film scores in archives at USC and the University of California, Los Angeles. It also draws on Eisler studies by such European scholars as Albrecht Betz, Jürgen Schebera, and Horst Weber, as well as on research of film music scholars Sally Bick and Claudia Gorbman. As there is little written on the particulars of Eisler's American years, this thesis presents new facts and new perspectives and aims at a better understanding of the artistic achievements of this composer.

Description
Speciation is the fundamental process that has generated the vast diversity of life on earth. The hallmark of speciation is the evolution of barriers to gene flow. These barriers may reduce gene flow either by keeping incipient species from hybridizing at all (pre-zygotic), or by reducing the fitness of hybrids (post-zygotic). To understand the genetic architecture of these barriers and how they evolve, I studied a genus of wasps that exhibits barriers to gene flow that act both pre- and post-zygotically. Nasonia is a genus of four species of parasitoid wasps that can be hybridized in the laboratory. When two of these species, N. vitripennis and N. giraulti are mated, their offspring suffer, depending on the generation and cross examined, up to 80% mortality during larval development due to incompatible genic interactions between their nuclear and mitochondrial genomes. These species also exhibit pre-zygotic isolation, meaning they are more likely to mate with their own species when given the choice. I examined these two species and their hybrids to determine the genetic and physiological bases of both speciation mechanisms and to understand the evolutionary forces leading to them. I present results that indicate that the oxidative phosphorylation (OXPHOS) pathway, an essential pathway that is responsible for mitochondrial energy generation, is impaired in hybrids of these two species. These results indicate that this impairment is due to the unique evolutionary dynamics of the combined nuclear and mitochondrial origin of this pathway. I also present results showing that, as larvae, these hybrids experience retarded growth linked to the previously observed mortality and I explore possible physiological mechanisms for this. Finally, I show that the pre-mating isolation is due to a change in a single pheromone component in N. vitripennis males, that this change is under simple genetic control, and that it evolved neutrally before being co-opted as a species recognition signal. These results are an important addition to our overall understanding of the mechanisms of speciation and showcase Nasonia as an emerging model for the study of the genetics of speciation.

Description
Este trabajo examina la producción literaria y cultural chicana/méxicosudoesteña de las distintas épocas coloniales del sudoeste: la época colonial española (1521-1821), la época colonial angloamericana (1848-1965) y la época poscolonial (1965-presente) para ver hasta qué punto siguen vigentes los legados coloniales dentro de un contexto contemporáneo. Avanzamos la hipótesis que, de la larga residencia histórica y geográfica de las personas hispanomexicanas en el sudoeste, se han producidos textos simbólicos donde se registran dos o más discursos residuos cuyo origen es una ideología dominante. El capítulo 1 plantea y detalla la hipótesis, reseña los numerosos estudios existentes, describe el marco teórico y da la división en capítulos. En el capítulo 2, se da de manera detallada el método crítico: la definición del colonialismo clásico según la teoría de Mario Barrera, la relación colonizador/colonizado aportada por Albert Memmi y los conceptos del tercer espacio híbrido, el mestizaje y el imaginario decolonial asociados con la época poscolonial como ofrecidos respectivamente por Homi Bhabha, Rafael Pérez-Torres y Emma Pérez. El capítulo 3 ofrece un análisis de la época colonial española vía dos obras nuevomexicanas: el poema épico Historia de la Nueva México (1610) de Gaspar Pérez de Villagrá y el drama Los comanches (c.1779) de anónimo. El capítulo 4 trata la colonización angloamericana en las obras The Squatter and the Don (1885) de María Amparo Ruiz de Burton y Dew on the Thorn (escrita en los 1940; publicada en 1997) de Jovita González de Mireles. El capítulo 5 examina la época poscolonial vía la obra Los muertos también cuentan (1995) de Miguel Méndez. Una lectura de la literatura chicana/méxicosudoesteña revela la presencia de varios personajes típicos asociados cada uno a una diferente época histórica desde el conquistador español hasta un mexicano recién inmigrado, quienes no han podido evadir la correspondiente presencia de un grupo dominante u colonizador. Con base en una investigación de las cinco obras seleccionadas, se muestra cómo las relaciones coloniales se forman y se transforman y luego se manifiestan en un contexto contemporáneo, desplazando por ende nuestro entendimiento de las relaciones coloniales como un simple proyecto binario de dominación y subordinación.

Description
Set in the former Yugoslavia, contemporary Bosnia and Herzegovina, and Midwest America, the collection of short stories follows the complicated trajectory of war-survivor to refugee and, then, immigrant. These stories---about religious prisoners who are not at all religious, about young, philosophizing boys tempting the bullets of snipers, about men retracing their fathers' steps over bridges that no longer exist---grapple with memory, imagination, and the nature of art, and explore the notion of writer as witness.

Description
This document is intended to show the various kinds of stylistically appropriate melodic and rhythmic ornamentation that can be used in the improvisation of the Sarabandes by J.S. Bach. Traditional editions of Bach's and other Baroque-era keyboard works have reflected evolving historical trends. The historical performance movement and other attempts to "clean up" pre-1950s romanticized performances have greatly limited the freedom and experimentation that was the original intention of these dances. Prior to this study, few ornamented editions of these works have been published. Although traditional practices do not necessarily encourage classical improvisation in performance I argue that manipulation of the melodic and rhythmic layers over the established harmonic progressions will not only provide diversity within the individual dance movements, but also further engage the ears of the performer and listener which encourages further creative exploration. I will focus this study on the ornamentation of all six Sarabandes from J.S. Bach's French Suites and show how various types of melodic and rhythmic variation can provide aurally pleasing alternatives to the composed score without disrupting the harmonic fluency. The author intends this document to be used as a pedagogical tool and the fully ornamented Sarabandes from J.S. Bach's French Suites are included with this document.

Description
The repertoire of the saxophone has advanced significantly since its invention circa 1840. Performers are required to adapt to the demands of composers - many of whom are exploring new and unconventional sounds and techniques. Numerous texts exist to identify and explain these so-called "extended" techniques, but there are very few resources for the initial stages of performance. In order to offer performers a resource, the author of this text composed forty original etudes (or studies) that incorporate extended techniques in a variety of ways. After identifying common extended techniques that a performer might face, the author focused on four different ways each individual technique might appear in actual repertoire. The resulting work is entitled Pushing Boundaries: Forty Etudes on Extended Techniques. Each etude offers a practical approach to what is generally a single extended technique. Although this text is not pedagogical in the sense of identifying the mechanics and anatomical requirements of each technique, it does contain a performance analysis of each etude. This analysis identifies areas where performers might struggle and offers helpful suggestions. To this end, the etudes accompanied by performance analysis provide a paced, systematic approach to the mastery of each technique.

Description
Modified and artificial water sources can be used as a management tool for game and non-game wildlife species. State, federal, and private agencies allocate significant resources to install and maintain artificial water sources (AWS) annually. Capture mark recapture methods were used to sample small mammal communities in the vicinity of five AWS and five paired control sites (treatments) in the surrounding Sonoran desert from October 2011 to May 2012. I measured plant species richness, density, and percent cover in the spring of 2012. A Multi-response Permutation Procedure was used to identify differences in small mammal community abundance, biomass, and species richness by season and treatment. I used Principle Component Analysis to reduce 11 habitat characteristics to five habitat factors. I related rodent occurrence to habitat characteristics using multiple and logistic regression. A total of 370 individual mammals representing three genera and eight species of rodents were captured across 4800 trap nights. Desert pocket mouse (Chaetodipus penicillatus) was the most common species in both seasons and treatments. Whereas rodent community abundance, biomass, and richness were similar between seasons, community variables of AWS were greater than CS. Rodent diversity was similar between treatments. Desert pocket mouse abundance and biomass were twice as high at AWS when compared to controls. Biomass of white-throated woodrat (Neotoma albigula) was five times greater at AWS. Habitat characteristics were similar between treatments. Neither presence of water nor distance to water explained substantial habitat variation. Occurrence of rodent species was associated with habitat characteristics. Desert rodent communities are adapted for arid environments (i.e. Heteromyids) and are not dependent on "free water". Higher abundances of desert pocket mouse at AWS were most likely related to increased disturbance and debris and not the presence of water. The results of this study and previous studies suggest that more investigation is needed and that short term studies may not be able to detect interactions (if any) between AWS and desert small mammal communities.
