Description
This thesis project examines the likely factors that cause students to drop out of Barrett, the Honors College. Honors literature regarding retention and attrition suggests four areas encompassing individual student attributes and honors program characteristics which may impact a student's decision to stay or leave an Honors College. The primary question in focus is, "Why do students leave the Honors College?" followed by the tertiary questions of, "what can be done to mitigate this occurrence?" and, "how does this affect the quality of an honors education?" Assessing attrition can be broken down into biographical, cognitive-behavioral, socio-environmental, and institutional-instrumental components. Students who graduated with honors and those who did not graduate with honors were assessed on these four components through survey methods and qualitative interviews to investigate specific reasons why students leave the honors program. The results indicated a wide array of reasons impacting student attrition, the most significant being negative perceptions towards (1) honors courses and contracts, (2) difficulty completing a thesis project, and (3) finding little to no value in "graduating with honors." Each of these reasons reflect the institutional-instrumental component of student attrition, making it the most salient group of reasons why students leave the Honors College. The socio-environmental component also influences student attrition through peer influence and academic advisor support, though this was found to be within the context of institutional-instrumental means. This project offers solutions to ameliorate each of the four components of attrition by offering standardized honors contracts and more mandatory honors classes, mandatory thesis preparatory courses instead of workshops, and emphasizing the benefit Barrett gives to students as a whole. These solutions aim at increasing graduation rates for future honors students at Barrett as well as improving the overall quality of an honors education.

Description
Undergraduate on-campus residential education is a topic of significant inquiry within the field of higher education, and specifically student affairs. It has become commonplace for institutions of higher education in the United States to leverage the intersections between academics and residence life in order to promote student success by offering on-campus housing options that strategically place students in residential communities that provide additional connection to the students' academic experience, often by major, college, department, or other focus areas. Such models vary by institution, but are often referred to as living-learning communities or residential colleges, depending upon their structure and goals. For example, Barrett, the Honors College on the Tempe campus of Arizona State University implements a residential college model within its student housing; honors students live and study together, with the addition of three "special communities" designed for students majoring in Engineering, Business, or the Arts. This honors thesis case study describes and investigates the impact the visual and performing arts Barrett residential community has upon its residents in their first-year college experience. Through the lens of student development theory, this research focuses upon examining this specific residential community in detail in order to gain an understanding of its effect upon residents' academic and personal well being.

Description
Additive Manufacturing and 3D printing are becoming important technologies in the manufacturing sector. The benefits of this technology include complex part geometry, short lead-times, low waste, and simple user interface. However, the technology does not come without its drawbacks: mainly the removal of support structures from the component. Traditional techniques that involve sawing and cutting can be expensive and take a long time, increasing the overall price of 3D printed metal components. This paper discusses two approaches taken for dissolvable support structures in 3D printed stainless steel (17-4 PH). For the first time in powder bed fusion components, with the help of Christopher Lefky and Dr. Owen Hildreth, dissolvable support capabilities are achieved in metal prints. The first approach, direct dissolution, involves direct corrosion of the entire part, leading to support removal. This approach is not self-terminating, and leads to changes in final component geometry. The second approach involves a post-build sensitization step, which physically alters the microstructure and chemical stability of the first 100-200 microns of the metal. The component is then etched at an electric potential that will readily corrode this sensitized surface, but not the underlying base metal. An electrolytic solution of HNO3/KCl/HCl paired with an anodic bias was used for the direct dissolution approach, resulting in a loss of about 120 microns of material from the components surface. For the self-limiting approach, surface sensitization was achieve through a post build annealing step (800 C for 6 hours, air cooled) with exposure to a sodium hexacynoferrate slurry. When the slurry decomposes in the furnace, carbon atoms diffuse into the surface and precipitate a chromium-carbide, which reduces the chemical stability of the stainless steel. Etching is demonstrated in an anodic bias of HNO3/KCl. To determine proper etching potentials, open circuit potential and cyclic voltammetry experiments were run to create Potentiodynamic Polarization Curves. Further testing of the self-terminating approach was performed on a 316 stainless steel interlocking ring structure with a complex geometry. In this case, 32.5 hours of etching at anodic potentials replaced days of mechanical sawing and cutting.

Description
Winglets and wingtip structures have been prominent in commercial aircraft design in the past few decades. These designs are known to reduce the induced drag on an aircraft wing, thus increasing its overall fuel efficiency. Several different winglet designs exist, and little reason is offered as to why different winglet designs are used in practice on different aircraft, especially those of variable range. This research tests existing winglets (no winglet, raked winglet, flat plate winglet, blended winglet, and wingtip fence) on a span-constrained wing planform design both computationally and in the wind tunnel. While computational tests using a vortex lattice code indicate that the wingtip fence minimizes induced drag and maximizes lift to drag ratio in most cases, wind tunnel tests show that at different lift coefficients and angles of attack, the raked winglet and blended winglet optimize the aerodynamic efficiency at incompressible flow velocities. Applying the wing aerodynamic data to existing variable range commercial aircraft, mission performance analysis is run on a Bombardier CRJ200, Airbus A320, and Airbus A340-300. By comparing flight lift coefficients in cruise for these aircraft to the lift coefficients at which winglets minimize drag in compressible flows, optimal winglet designs are chosen. It is found that the short range CRJ200 is best equipped with a flat plate or blended winglet, the medium range A320 can reduce drag with either a wingtip fence, raked winglet, or blended winglet, and the long range A340 performs best with a flat plate, blended, or raked winglet. Overall, despite the discrepancy in winglet selection depending on which experimental results are used, it is clear that addition of a winglet to a span-constrained wing is beneficial in that it reduces induced drag and therefore increases overall fuel efficiency.

Description
Composite structures, particularly carbon-fiber reinforced polymers (CFRPs) have been subject to significant development in recent years. They have become increasingly reliable, durable, and versatile, finding a role in a wide variety of applications. When compared to conventional materials, CFRPs have several advantages, including extremely high strength, high in-plane and flexural stiffness, and very low weight. However, the application of CFRPs and other fiber-matrix composites is complicated due to the manner in which damage propagates throughout the structure, and the associated difficulty in identifying and repairing such damages prior to structural failure. In this paper, a methods of detecting and localizing delaminations withint a complex foam-core composite structure using non-destructive evaluation (NDE) and structural health montoring (SHM) is investigated. The two NDE techniques utilized are flash thermography and low frequency ultrasonic C-Scan, which were used to confirm the location of seeded damages within the specimens and to quantify the size of the damages. Macro fiber composite sensors (MFCs) and piezoelectric sensors (PZTs) were used as actuators and sensors in pitch-catch and pulse-echo configurations in order to study mode conversions and wave reflections of the propagated Lamb waves when interacting with interply delaminations and foam-core separations. The final results indicated that the investigated NDE and SHM techniques are capable of detecting and quantifying damages within complex X-COR composites, with the SHM techniques having the potential to be used \textit{in situ} with a high degree of accuracy. It was also observed that the presence of the X-COR significantly alters the behavior of the wave when compared to a standard CFRP composite plate, making it necessary to account for any variations if wave-base techniques are to be used for damage detection and quantification. Lastly, a time-space model was created to model the wave interactions with damages located within X-COR complex sandwich composites.

Description
Every year, millions of people find themselves displaced from their homes because of fear or threats of violence. Some of these people will become refugees, who will then be resettled in the United States. In order to help with the resettlement process, refugees are given cultural orientations through their resettlement organizations. The Phoenix Police Department teaches one of these cultural orientations for local resettlement agencies in order to dispel some of the fears refugees have about law enforcement and build a stronger relationship with the refugee community. Past research on this topic has been limited within the United States, but communities are still trying to figure out how to interact with refugees despite not knowing how to do it. There are various possible complications inherent in the integration process and many potential methods of trust building available to the refugee community and public services like law enforcement. This project seeks to understand the refugee resettlement process through field observation of the cultural orientation taught by the Phoenix Police Department and interviews with detectives familiar with the process in Phoenix. Cultural and language differences as well as lack of education and research on the topic of refugee resettlement are all key points in comprehending what the police, refugees, and resettlement organizations are doing during the integration process. Once these issues are addressed to alleviate gaps in knowledge about refugees, it may be possible to adjust the process to be easier for stakeholders involved in refugee resettlement.

Description
This creative project is a collection of profiles focused on Arizona nonprofits and refugees. The profiles share stories of refugees, volunteers, employees and others involved in the community serving refugees. Nonprofits are a vital resource for refugee resettlement. These organizations offer services to support refugees as they transition into new communities. Some services include: housing, English language learning, cultural orientation, job placement, medical treatment, education, and farming. Each of these programs support resiliency for refugees and for the communities in which they live. We Are Resilient was created first, to show the important role nonprofits have in serving refugees. Second, to connect people to a few of the stories and experiences within the Arizona refugee community. And third, to build understanding of the strength refugees bring to communities of Arizona and by extension the country. Visit weareresilientaz.com to learn more.

Description
Postmodernism has been one of the dominant modes of thought in literature and philosophy since the 1960s, but its roots go back much further. This thesis is an examination of Brechtian frameworks in an assortment of popular postmodern works. Both literary texts, such as novels, films, and music, and philosophical texts are used to form a general understanding of the postmodern project, and these concepts are then placed in conversation with ideas from the works of the 20th century German playwright Bertolt Brecht. I found that despite certain differences, the central ideas of postmodernism can be seen as the extension of Brecht’s philosophy, especially his concept of the Verfremdungseffekt. First, multiplicity—in perspectives and understandings—can be seen as an attempt to achieve this Verfremdungseffekt in the reader, and second, transgression in these texts can be used to evoke the same feeling. Many of the identifying techniques of postmodernism, e.g. juxtaposition, unreliable narrator, self-reference, and so on, can be interpreted as the extension of ideas pioneered by Brecht in the 1920s and 1930s. My thesis illustrates these connections.
