Description
MOVE was a choreographic project that investigated content in conjunction with the creative process. The yearlong collaborative creative process utilized improvisational and compositional experiments to research the movement potential of the human body, as well as movement's ability to be an emotional catalyst. Multiple showings were held to receive feedback from a variety of viewers. Production elements were designed in conjunction with the development of the evening-length dance work. As a result of discussion and research, several process-revealing sections were created to provide clear relationships between pedestrian/daily functional movement and technical movement. Each section within MOVE addressed movement as an emotional catalyst, resulting in a variety of emotional textures. The sections were placed in a non-linear structure in order for the audience to have the space to create their own connections between concepts. Community was developed in rehearsal via touch/weight sharing, and translated to the performance of MOVE via a communal, instinctive approach to the performance of the work. Community was also created between the movers and the audience via the design of the performance space. The production elements all revolved around the human body, and offered different viewpoints into various body parts. The choreographer, designers, and movers all participated in the creation of the production elements, resulting in a clear understanding of MOVE by the entire community involved. The overall creation, presentation, and reflection of MOVE was a view into the choreographer's growth as a dance artist, and her values of people and movement.

Description
Efficiency of components is an ever increasing area of importance to portable applications, where a finite battery means finite operating time. Higher efficiency devices need to be designed that don't compromise on the performance that the consumer has come to expect. Class D amplifiers deliver on the goal of increased efficiency, but at the cost of distortion. Class AB amplifiers have low efficiency, but high linearity. By modulating the supply voltage of a Class AB amplifier to make a Class H amplifier, the efficiency can increase while still maintaining the Class AB level of linearity. A 92dB Power Supply Rejection Ratio (PSRR) Class AB amplifier and a Class H amplifier were designed in a 0.24um process for portable audio applications. Using a multiphase buck converter increased the efficiency of the Class H amplifier while still maintaining a fast response time to respond to audio frequencies. The Class H amplifier had an efficiency above the Class AB amplifier by 5-7% from 5-30mW of output power without affecting the total harmonic distortion (THD) at the design specifications. The Class H amplifier design met all design specifications and showed performance comparable to the designed Class AB amplifier across 1kHz-20kHz and 0.01mW-30mW. The Class H design was able to output 30mW into 16Ohms without any increase in THD. This design shows that Class H amplifiers merit more research into their potential for increasing efficiency of audio amplifiers and that even simple designs can give significant increases in efficiency without compromising linearity.

Description
Assyrians face numerous concerns resulting from the status of a stateless people. Overcoming immigrant transitions, difficulties related to diaspora, and the implications of these on Assyrian culture are pressing matters to be addressed in the evolution of the Assyrian nation. In order to develop a strategy to benefit individuals, families and the nation, Hometown Associations, a form of nonprofit organization, may be used to connect, assist, and progress Assyrian communities. This thesis provides background, rationale for, and guidelines to creating Hometown Associations for Assyrian communities. Ultimately, Hometown Associations and other forms of cultural organizations appear to be a viable means toward community solidarity and cultural preservation. However, further research and more diverse subjects are required to assess the generalizeability of the findings discussed.

Description
In the university setting, when a person wants to conduct research that deals with human subjects, they are required to receive the approval of their Institutional Review Board (IRB). This process takes place to ensure the proposed research is ethical and poses minimal risks to the willing subject. In Indian Country, there is a growing trend where American Indian nations are taking control over regulating research that is conducted within their jurisdictional boundaries.
In my thesis, I discuss the historical background that has led to the IRBs academics are familiar within universities they see today. In addition, I discuss the body of literature that addresses IRBs, human subjects, and the debate on which research should or should not be regulated by universities. I will then, critically analyze the established research protocols that exist in Arizona American Indian tribes. I use Darrell Posey's (1996) idea of Community Controlled Research (CCR) as the framework for my analysis. CCR dictates the people of the community decide the ways in which research is conducted. The purpose of my research is to create recommendations that will assist and inform tribes how to either, strengthen their existing protocols, or create a research protocol that will promotes Community Controlled Research.

Description
This research addresses the ability for neighborhoods to assess resiliency as it applies to their respective local areas. Two demographically and economically contrasting neighborhoods in Glendale, Arizona were studied to understand what residents' value and how those values link to key principles of resiliency. Through this exploratory research, a community-focused process was created to use these values in order to link them to key principles of resiliency and potential measureable indicators. A literature review was conducted to first assess definitions and key principles of resiliency. Second, it explored cases of neighborhoods or communities that faced a pressure or disaster and responded resiliently based on these general principles. Each case study demonstrated that resiliency at the neighborhood level was important to its ability to survive its respective pressure and emerge stronger. The Heart of Glendale and Thunderbird Palms were the two neighborhoods chosen to test the ability to operationalize neighborhood resiliency in the form of indicators. First, an in-depth interview was conducted with a neighborhood expert to understand each area's strengths and weaknesses and get a context for the neighborhood and how it has developed. Second, a visioning session was conducted with each neighborhood consisting of seven participants to discuss its values and how they relate to key principles of resiliency. The values were analyzed and used to shape locally relevant indicators. The results of this study found that the process of identifying participants' values and linking them to key principles of resiliency is a viable methodology for measuring neighborhood resiliency. It also found that indicators and values differed between the Heart of Glendale, a more economically vulnerable yet ethnically diverse area, than Thunderbird Palms, a more racially homogenous, middle income neighborhood. The Heart of Glendale valued the development of social capital more than Thunderbird Palms which placed a higher value on the condition of the built environment as a vehicle for stimulating vibrancy and resiliency in the neighborhood. However, both neighborhoods highly valued public education and providing opportunities for children to be future leaders in their local communities.

Description
Many studies have shown that access to healthy food in the US is unevenly distributed and that supermarkets and other fresh food retailers are less likely to be located in low-income minority communities, where convenience and dollar stores are more prevalent grocery options. I formed a partnership with Phoenix Revitalization Corporation, a local community development organization engaged in Central City South, Phoenix, to enhance the community's capacity to meet its community health goals by improving access to healthy food. I used a community-based participatory approach that blended qualitative and quantitative elements to accommodate collaboration between both academic and non-academic partners. Utilizing stakeholder interviews, Nutrition Environment Measures Surveys (NEMS), and mapping to analyze the community's food resources, research revealed that the community lacks adequate access to affordable, nutritious food. Community food stores (n=14) scored an average of 10.9 out of a possible 54 points using the NEMS scoring protocol. The community food assessment is an essential step in improving access to healthy food for CCS residents and provides a baseline for tracking progress to improve residents' food access. Recommendations were drafted by the research partnership to equip and empower the community with strategic, community-specific interventions based on the research findings.

Description
Class D Amplifiers are widely used in portable systems such as mobile phones to achieve high efficiency. The demands of portable electronics for low power consumption to extend battery life and reduce heat dissipation mandate efficient, high-performance audio amplifiers. The high efficiency of Class D amplifiers (CDAs) makes them particularly attractive for portable applications. The Digital class D amplifier is an interesting solution to increase the efficiency of embedded systems. However, this solution is not good enough in terms of PWM stage linearity and power supply rejection. An efficient control is needed to correct the error sources in order to get a high fidelity sound quality in the whole audio range of frequencies. A fundamental analysis on various error sources due to non idealities in the power stage have been discussed here with key focus on Power supply perturbations driving the Power stage of a Class D Audio Amplifier. Two types of closed loop Digital Class D architecture for PSRR improvement have been proposed and modeled. Double sided uniform sampling modulation has been used. One of the architecture uses feedback around the power stage and the second architecture uses feedback into digital domain. Simulation & experimental results confirm that the closed loop PSRR & PS-IMD improve by around 30-40 dB and 25 dB respectively.

Description
Driven by concern over environmental, economic and social problems, small, place based communities are engaging in processes of transition to become more sustainable. These communities may be viewed as innovative front runners of a transition to a more sustainable society in general, each one, an experiment in social transformation. These experiments present learning opportunities to build robust theories of community transition and to create specific, actionable knowledge to improve, replicate, and accelerate transitions in real communities. Yet to date, there is very little empirical research into the community transition phenomenon. This thesis empirically develops an analytical framework and method for the purpose of researching community transition processes, the ultimate goal of which is to arrive at a practice of evidence based transitions. A multiple case study approach was used to investigate three community transitions while simultaneously developing the framework and method in an iterative fashion. The case studies selected were Ashton Hayes, a small English village, BedZED, an urban housing complex in London, and Forres, a small Scottish town. Each community was visited and data collected by interview and document analysis. The research design brings together elements of process tracing, transformative planning and governance, sustainability assessment, transition path analysis and transition management within a multiple case study envelope. While some preliminary insights are gained into community transitions based on the three cases the main contribution of this thesis is in the creation of the research framework and method. The general framework and method developed has potential for standardizing and synthesizing research of community transition processes leading to both theoretical and practical knowledge that allows sustainability transition to be approached with confidence and not just hope.

Every body holds a story. Those stories are rich with physical movements to be expressed, and through the physical expression comes self-awareness and transformation. A partnership between Arizona State University and Arcadia High School was the vehicle in which I implemented a curriculum built around somatic experiences and communal beliefs and values. The framework for this investigated curriculum teaches students' embodiment of self, tolerance and acceptance in collaboration, life skills through applied constructivist principles, and increased critical thinking and problem-solving abilities. This research involved somatic exercises enabling participants to have insight into natural moving patterns, how such patterns relate to others and outside environments. Research concluded with collective dialogue around individual and shared experiences. I worked twice per week with a choreography class with a four unit curriculum. From varying modes of assessment (e.g., one-on-one interviews, group discussions, journals, surveys, ongoing observations) students' responses to this type of curriculum ranged from excitement and curiosity to frustrating and provoking. Although these areas of research are not necessarily new to the field of dance and education, gaps in dialogue, published work, and reliable resources prove these theories and methods are still valued and necessary. This research demonstrates the imperative demand in dance education for deeper connections of self-discovery.

Description
The United States resettles more refugees each year than any country, yet little is known about the influence that the Refugee Resettlement Program has on our communities. Program evaluation in the United States is primarily concerned with outcomes and efficiency; while there has been an absence of collecting data to measure the impact that social programs have on communities. This study explores the impact of refugee resettlement on a metropolitan area by surveying professionals with experience working or volunteering with refugee populations. These professionals rate the extent to which they believe refugee resettlement influences social, economic, and environmental variables in the community, and explain the nature of the influence they believe the program has on the community. The data collected from these surveys will introduce the perceived impact of refugee resettlement from the perspective of those with professional experience in the area. By exploring the effects that the Refugee Resettlement Program has on Phoenix, this data can assist in the creation of community assessments for refugee resettlement and comparable social programs.
