abstract: This study examined discussion forum posts within a website dedicated to a medium and genre of music (chiptunes) with potential for music-centered making, a phrase I use to describe maker culture practices that revolve around music-related purposes. Three research questions guided this study: (1) What chiptune-related practices did members of chipmusic.org discuss between December 30th, 2009 and November 13th, 2017? (2) What do chipmusic.org discussion forum posts reveal about the multidisciplinary aspects of chiptunes? (3) What import might music-centered making evident within chipmusic.org discussion forum posts hold for music education? To address these research questions, I engaged in corpus-assisted discourse analysis tools and techniques to reveal and analyze patterns of discourse within 245,098 discussion forum posts within chipmusic.org. The analysis cycle consisted of (a) using corpus analysis techniques to reveal patterns of discourse across and within data consisting of 10,892,645 words, and (b) using discourse analysis techniques for a close reading of revealed patterns. Findings revealed seven interconnected themes of chiptune-related practices: (a) composition practices, (b) performance practices, (c) maker practices, (d) coding practices, (e) entrepreneurial practices, (f), visual art practices, and (g) community practices. Members of chipmusic.org primarily discussed composing and performing chiptunes on a variety of instruments, as well as through retro computer and video game hardware. Members also discussed modifying and creating hardware and software for a multitude of electronic devices. Some members engaged in entrepreneurial practices to promote, sell, buy, and trade with other members. Throughout each of the revealed themes, members engaged in visual art practices, as well as community practices such as collective learning, collaborating, constructive criticism, competitive events, and collective efficacy. Findings suggest the revealed themes incorporated practices from a multitude of academic disciplines or fields of study for music-related purposes. However, I argue that many of the music-related practices people discussed within chipmusic.org are not apparent within music education discourse, curricula, or standards. I call for an expansion of music education discourse and practices to include additional ways of being musical through practices that might borrow from multiple academic disciplines or fields of study for music-related purposes. / Dissertation/Thesis / Doctoral Dissertation Music Education 2018

This study aimed to provide an in-depth understanding of the way in which the macro, meso, and micro levels of the health care system affects nutrition care practices of family physicians (FPs) and nurse practitioners (NPs). It also examined how current practices compare to the clinical practice guidelines on the management and prevention of obesity. Three different types of team-based primary care settings were included: 2 Family Health Teams, 3 Community Health Centres and 1 Nurse Practitioner-Led Clinic. Within each type of setting, six to eight FPs and NPs were interviewed (for a total n= 20). Site-specific documents and government reports were also analyzed. Findings suggest that the team-based nature improves nutrition care due to the accessibility to dietitians and cost-free service. Electronic Medical Records was an important enabler for chronic disease management. Duration of medical visits and increasing prevalence of complex patients were barriers for addressing nutrition and weight. Despite the importance of addressing obesity in primary care, the topic was approached in terms of chronic disease management rather than prevention. FPs and NPs spared the dietitian on site for patients who have more severe chronic conditions. Nevertheless, the presence of a dietitian on site increased the likelihood of primary care providers bringing up the topic of nutrition. Addressing site-specific barriers could improve nutrition care practices for weight management and chronic disease prevention in the primary care setting.

La recherche de configurations d’aéronefs plus efficaces mène les ingénieurs à explorer de nouveaux concepts tels que l’aile volante, l’aile haubanée ou l’aile en jointive. Contrairement à la configuration classique aile-fuselage, qui est bien connue et étudiée, le comportement en vol de ces nouveaux concepts d'avion est peu connu. Dans ce contexte, la conception, la construction et les essais de modèles à l'échelle aéroélastiquement semblables se présentent comme un moyen peu risqué d'acquérir des connaissances expérimentales sur ces nouveaux concepts. Un modèle aéroélastiquement semblable présente le même comportement aéroélastique (mis à l’échelle) que l’avion de référence à échelle réelle. En général, le même comportement aéroélastique implique de reproduire les mêmes déplacements pour des conditions du flux d’air données, ainsi que les mêmes vitesses de flottement ou de divergence statique mises à l'échelle. Pour résoudre le problème de similitude, l'approche est divisée en trois parties. Dans le premier cas, nous traitons le problème de similitude aéroélastique lorsque les paramètres de similitude du flux aérodynamique peuvent être complètement préservés. Dans cette situation, le problème consiste simplement à reproduire la réponse dynamique modale de l’aile mise à l'échelle en optimisant les propriétés de la structure et de la masse. Dans la deuxième partie, nous nous concentrons sur l’optimisation du design de la forme de l’aile pour reproduire la réponse du flottement lorsque les paramètres de remise à l’échelle du flux aérodynamique ne peuvent pas être atteints. / The search for more efficient aircraft configurations leads designers to explore new concepts such as the blended wing body, the strut-braced wing, or the box wing. Unlike the classical wing-fuselage configuration, which is well known and understood, few is known about the in-flight behavior of these new aircraft concepts. In that context, the design, construction, and testing of unmanned aeroelastically scaled models presents itself as a low-risk means of acquiring experimental knowledge on these new concepts. An aeroelastically scaled model exhibits the same scaled aeroelastic behavior as the full-scale reference aircraft. Typically, the same aeroelastic behavior implies matching the displacements for some given scaled airflow conditions, as well as the scaled flutter or static divergence speeds. To address the similarity problem, we divide the approach in three parts. In the first one we deal with the aeroelastic similarity problem when the aerodynamic flow scaling conditions can be completely preserved. In that situation, the problem is reduced to simply matching the scaled modal dynamic response of the wing through optimization of the structure and mass properties. In the second part, we focus on the wing planform design optimization to match the flutter response when the airflow scaling parameters cannot be achieved.

Cancer patients worldwide receive care from multidisciplinary teams, and patients sometimes have little or no knowledge about the different treatment options available, making communication with their care providers an important influence in how they perceive their care. Patient satisfaction with care is an important factor in determining survivorship. The increasing prevalence of cancer worldwide has become a huge public health issue. The World Health Organization has warned that the potential gains from combatting infectious diseases in Nigeria might be lost because of the increasing prevalence of cancer. The purpose of this grounded theory study was to obtain the perceptions of 30 cancer survivors in Nigeria about their care in federally funded hospitals to improve cancer care in the country. Through a constructivist grounded theory (CGT) approach, data from 30 in-depth interviews with the cancer survivors were analyzed. Data analysis included open coding, selective coding, theoretical coding, and memo writing. Three themes emerged from the data analysis: positive perception of care (P), service improvement (S), and good care experience (G), all of which were cyclically related to form the PSG substantive theory, which indicates that better health care to cancer patients will improve preventative and curative cancer care services in Nigeria. This theory was validated by relating it to 3 theories in the literature as recommended in CGT research. The implication for positive social change is that the results might provide information that can help health care professionals to improve how they communicate with, relate to, and care for cancer patients and their families in Nigeria and other countries.

Testing is an integral part of a satellite’s development, requirements verification and risk mitigation efforts. A robust test program serves to verify construction, integration and assembly workmanship, ensures component, subsystem and system level functionality and reduces risk of mission or capability loss on orbit. The objective of this thesis was to develop a detailed test program for pico-satellites with a focus on the Cal Poly CubeSat architecture. The test program established a testing baseline from which other programs or users could tailor to meet their needs. Inclusive of the test program was a detailed decomposition of discrete and derived test requirements compiled from the CubeSat and Launch Vehicle communities, military guidelines, and industry standards. The test requirements were integrated into a methodical, efficient and risk adverse test flow for verification.

This project develops a quantitative method to evaluate the seismic risk for portable GSE at Vandenberg Air Force Base. Using the latest probability data available from the USGS, risk thresholds are defined for portable GSE having the potential to cause a catastrophic event. Additionally, an example tool for design engineers was developed from the seismic codes showing the tipping hazard case can be simplified into strict geometrical terms. The misinterpretation and confusion regarding the Range Safety 24 Hour Rule exemption can be avoided by assessing seismic risk for portable GSE. By using the methods herein to quantify and understand seismic risk, more informed risk decisions can be made by engineering and management. The seismic codes and requirements used and referenced throughout include but are not limited to IBC, ASCE 7, EWR 127-1, and AFSPCMAN 91-710.

Unmanned Aerial Systems (UAS) are a growing asset. Currently UAS are on the cutting edge with resources being spent developing the capabilities mostly for military use. This project is intended to create a system for non-defense customers. Specifically, the Operationally Responsive Aircraft (ORA) will appeal to academic institutions, individual consumers, future customers new to the UAS industry, as well as anybody trying to get airtime for custom sensors. The system developed in this project utilizes dual aluminum external payload bays attached to a ParkZone Radian aircraft. Each external payload bay can contain approximately 500 $\text{cm}^3$, with a height and width limit of 4.1 cm and 11.0 cm respectively. The custom sensors must weigh less than or equal to 3.2 lbs combined. The external payload bays were designed to hold an imaging payload which produces a composite map of the land surveyed. The system incorporates an Arduino Uno, SD Shield, as well as a CMOS camera and board. The processor saves individual images to an SD card. Once the aircraft has landed, the operator combines the images with Microsoft Research Image Composite Editor to create the composite map. This imaging payload has a NIIRS value of 4.0 +/- 0.4, which is equivalent to identifying a basketball court within a residential environment.

The Naval Postgraduate School is currently developing their first CubeSat, the Solar Cell Array Tester CubeSat, or NPS-SCAT. Launching a CubeSat, such as NPS-SCAT, requires environmental testing to ensure not only the success of the mission, but also the safety of other CubeSats housed in the same deployer. This thesis will address the development of CubeSat vibration testing methodology at NPS, including subsystem testing, engineering unit qualification, and flight unit testing. In addition, the new Cal Poly CubeSat Test POD Mk III will be introduced and evaluated based upon comparison with the Poly Picosatellite Orbital Deployer (P-POD). Using examples from the development of NPS-SCAT and test data from Cal Poly’s Test POD Mk III and P-POD, the current CubeSat testing methodology will be verified and an improved method for NPS CubeSat subsystem testing will be presented.
