Description
In response to the rapid rise of emerging markets, shorter product lifecycles, increasing global exchange and worldwide competition, companies are implementing `sustainable development' as a mechanism by which to maintain competitive global advantage. Sustainable product development approaches used in industry focus mainly on environmental issues, and to a certain extent on social and economic aspects. Unfortunately, companies have often ignored or are unsure of how to deal with the cultural dimensions of sustainable product development. Multi-nationals expanding their business across international boundaries are agents of cultural change and should be cognizant of the impact their products have on local markets. Companies need to develop a deeper understanding of local cultures in order to design and deliver products that are not only economically viable but also culturally appropriate. To demonstrate applicability of cultural appropriate design, this research undertakes a case study of food systems in India specifically focusing on the exchange of fresh fruits and vegetables (FFV). This study focuses on understanding the entire supply chain of FFV exchange, which includes consumer experiences, distribution practices and production processes. This study also compares different distribution channels and exchange practices and analyzes the pattern of authority between different players within the distribution network. The ethnographic methods for data collection included a photo-journal assignment, shop-along visits, semi-structured interviews, a participatory design activity and focus group studies. The study revealed that traditional retail formats like pushcart vendors, street retailers and city retail markets are generally preferred over modern retail stores. For consumers, shopping is a non-choreographed activity often resulting in exercising, socializing and accidental purchases. Informal communication, personal relationships and openness to bargaining were important aspects of the consumer-retailer relationship. This study presents cultural insights into interactions, artifacts and contexts relevant to FFV systems in India. It also presents key implications for the field of design, design research, cultural studies, consumer research and sustainability. The insights gained from this study will act as guidelines for designers, researchers and corporations interested in designing products and services that are culturally appropriate to contexts of production, distribution and consumption.

Description
This dissertation examined sojourner adjustment success utilizing a unique method for collecting and analyzing the perceptions and sense making of the sojourner participants. Although previous research studies in this area have mostly relied on quantitative survey designs and researcher-generated models, this study relied on in-depth, participant-driven, qualitative interviews that were semi-structured using a software-assisted method called Interpretive Structural Modeling (ISM). Through this dissertation research, study abroad students (sojourners) had the opportunity to reflect on their sojourn experience, share their adjustment stories, and identify factors that were personally relevant to their success. This study broke new ground while building on the vast body of work in cross-cultural and sojourner adjustment. Sojourners were asked to provide their perspectives on the relationships among those factors reported in the literature that are commonly believed to influence successful adjustment. This allowed me to connect existing literature on the subject with the lived experience of the sojourner participants. This dissertation sought to answer two research questions. First, what factors do participants identify as being keys to the success of their sojourn? Second, what relationships do participants perceive among the factors contributing to successful sojourner adjustment? This dissertation found that language proficiency played a key role in their adjustment and openness was the factor most selected by participants in their explanation of a successful sojourn. Additionally, participant profiles and influence structure summaries provided evidence of the relationships participants saw among success factors in their lived experiences. In terms of preparing sojourners for going abroad, analysis of the composite structure revealed what could be prioritized in pre-departure training for impending sojourners. Themes emerged which provide insight into the commonalities of the sojourner experience despite differences in one's program or personality. This dissertation also explained additional success factors participants identified (e.g., ability to manage language fatigue, creation of connections with other travelers) that were not initially provided to them. Finally, suggestions for study abroad students/coordinators, researchers, and employers are provided.

Description
The history of the American Old West has frequently been romanticized and idealized. This dissertation study explored four Arizona towns that developed during the era of the American Old West: Tombstone, Jerome, Oatman, and Globe. The study broadly examined issues of remembering/forgetting and historical authenticity/myth. It specifically analyzed historic tourist destinations as visual phenomenon: seeking to understand how town histories were visually communicated to contemporary tourists and what role historically-grounded visual narratives played in the overall tourist experience. The study utilized a visual methodology to organize and structure qualitative data collection and analysis; it incorporated visual data from historic and contemporary photographs and textual data from observations and interviews. Through a careful exploration of each town's past and present, the research proposed a measure to assess how the strength of visual connections between past and present impacted tourist impressions of each town. The analysis suggested that, due to a general lack of historic knowledge, tourist impressions were more closely connected to contemporary experiences and prior expectations of the American Old West than to historically-grounded visual narratives.

Description
The People's Republic of China's inexorable ascendancy has become an epochal event in international landscape, accentuated by its triple national ceremonies of global significance: 2008 Beijing Olympic Games, 2009 Beijing Military Parade, and 2010 Shanghai World Expo. At a momentous juncture when the PRC endeavored to project a new national identity to the outside world, these ceremonial occasions constitute a high-stake communicative opportunity for the Chinese government and a fruitful set of discursive artifacts for symbolic deconstruction and rhetorical interpretation. To unravel these ceremonial spectacles, a public memory approach, with its versatile potencies indexical of a nation's interpretive system of social meaning, its normative framework of ideological model, and its past-present-future interrelationships, is contextually, conceptually, and analytically diagnostic of a rising China's sociopolitical constellations. Thus employing public memory as a conceptual-methodological matrix, my dissertation focuses on the prominent texts in these ceremonies, excavates their historico-memorial invocation and sociocultural persuasion, and plumbs their discursive agenda, rhetorical operation, and sociopolitical implication. I argue that the Chinese government deliberately and forcefully strove for three interrelated communicative objectives at these three ceremonies--re-imaging, re-asserting, and re-anchoring its national identity as an ancient, emergent superpower. Yet in contemporary Chinese context, its discursive (con)quest to recast its leadership as a historically continuous, culturally orthodox, and ideologically legitimate regime has always been compromised by its mythologized historical representation and hegemonic rhetorical reconfiguration, countervailed by its political and ideological fragility, and contested by domestic and global publics. Besides its contributions to the current conversation on the PRC's ceremonial phenomena, discursive formations, and communicative dynamics, this dissertation further offers its diagnosis and prognostication of this projected leading country in the 21st century.

Description
This dissertation examines the organizational discourse of business meetings in a Kuwaiti financial organization (Innovative Kuwait Co., pseudonym) and an American non-profit trade organization (Global Phoenix, pseudonym). Specifically, I explore the discourse and social identities, agency, and power used in staff members' task-oriented business meetings (Bargiela-Chiappini & Harris, 1997). The study is based on ethnographic business meetings data collected during eight months of fieldwork in 2010, 2011 and 2012. I used three major qualitative methodologies: observation, audio recording, and feedback focus group. In this study, I propose three research questions: 1) How does agency of staff members reflect membership in the corporate culture of an organization as a whole? 2) How is power used in relation to agency in business meetings? And 3) How are discourse and social identities of staff members enacted in business meetings? The analyses of ethnographic and fieldwork data demonstrate similar and different business linguistic behaviors in the two companies. In Innovative Kuwait Co., male managers are responsible for opening and closing the meetings. They also perform power by using language directives and suggestions directed to staff members. In contrast, female staff members in the Kuwaiti company participated insignificantly in meetings and produce more nonverbal cues. However, in one meeting, a female manager organized the discussion by controlling topics and giving directions. In Global Phoenix, female managers outnumber their male counterparts; therefore, agency, power, discourse, and social identities are performed differently. Female managers are responsible for opening and closing the meetings and for organizing the overall discussions. Additionally, female and male staff members participate equally and they interrupted their colleagues less frequently compared to staff members in Kuwait. Interestingly, American staff members laugh and joke more together than staff members in Kuwait. The findings of this dissertation will contribute to existing linguistic literature on business discourse and the examination of social meanings and structures in organizations, explaining how language shapes the actions and relationships of business staff members. This dissertation will also encourage business people to become mindful of the role of language and language training in developing and maintaining the corporate culture of their organizations.

Description
This dissertation explores South Asian American (SAA) emerging adult daughters' roles as their parents' reluctant confidants and mediators of conflict. Using Petronio's (2002) communication privacy management theory (CPM) as a framework, this dissertation investigates daughters' communicative strategies when engaged in familial roles. Findings from 15 respondent interviews with SAA women between the ages of 18 and 29 reveal daughters' intrinsic and extrinsic motivations for role-playing within their families, such as inherent satisfaction and parental expectations, respectively. Additionally, findings highlight daughters' use of coping and thwarting strategies after they become the recipients of their parents' unsolicited private information. Namely, daughters engaged in coping strategies (e.g., giving advice) to help their parents manage private information. Likewise, they enacted thwarting strategies (e.g., erecting territorial markers) to restore boundaries after their parents (the disclosers) violated them. Consequently, serving as parental confidants and mediators contributed to parent-child boundary dissolution and adversely affected daughters' well-being as well as their progression toward adulthood. This study provides theoretical contributions by extending CPM theory regarding reluctant confidants within the contexts of emerging adult child-parent relationships and ethnic minority groups in America. Practically, this study offers emerging adult children insight into how they might renegotiate boundaries when their parents change the relationship by disclosing personal information. Information gleaned from this study provides SAA emerging adult daughters with an understanding of the ramifications of prioritizing their familial roles and being a reluctant confidant, in addition to potential avenues for remediation.

Description
The purpose of this study was to observe the effectiveness of the phenylalanyl arginine β-naphthylamide dihydrochloride inhibitor and Tween 20 when combined with an antibiotic against Escherichia. coli. As antibiotic resistance becomes more and more prevalent it is necessary to think outside the box and do more than just increase the dosage of currently prescribed antibiotics. This study attempted to combat two forms of antibiotic resistance. The first is the AcrAB efflux pump which is able to pump antibiotics out of the cell. The second is the biofilms that E. coli can form. By using an inhibitor, the pump should be unable to rid itself of an antibiotic. On the other hand, using Tween allows for biofilm formation to either be disrupted or for the biofilm to be dissolved. By combining these two chemicals with an antibiotic that the efflux pump is known to expel, low concentrations of each chemical should result in an equivalent or greater effect on bacteria compared to any one chemical in higher concentrations. To test this hypothesis a 96 well plate BEC screen test was performed. A range of antibiotics were used at various concentrations and with varying concentrations of both Tween and the inhibitor to find a starting point. Following this, Erythromycin and Ciprofloxacin were picked as the best candidates and the optimum range of the antibiotic, Tween, and inhibitor were established. Finally, all three chemicals were combined to observe the effects they had together as opposed to individually or paired together. From the results of this experiment several conclusions were made. First, the inhibitor did in fact increase the effectiveness of the antibiotic as less antibiotic was needed if the inhibitor was present. Second, Tween showed an ability to prevent recovery in the MBEC reading, showing that it has the ability to disrupt or dissolve biofilms. However, Tween also showed a noticeable decrease in effectiveness in the overall treatment. This negative interaction was unable to be compensated for when using the inhibitor and so the hypothesis was proven false as combining the three chemicals led to a less effective treatment method.

Description
An in-depth analysis on the effects vortex generators cause to the boundary layer separation that occurs when an internal flow passes through a diffuser is presented. By understanding the effects vortex generators demonstrate on the boundary layer, they can be utilized to improve the performance and efficiencies of diffusers and other internal flow applications. An experiment was constructed to acquire physical data that could assess the change in performance of the diffusers once vortex generators were applied. The experiment consisted of pushing air through rectangular diffusers with half angles of 10, 20, and 30 degrees. A velocity distribution model was created for each diffuser without the application of vortex generators before modeling the velocity distribution with the application of vortex generators. This allowed the two results to be directly compared to one another and the improvements to be quantified. This was completed by using the velocity distribution model to find the partial mass flow rate through the outer portion of the diffuser's cross-sectional area. The analysis concluded that the vortex generators noticeably increased the performance of the diffusers. This was best seen in the performance of the 30-degree diffuser. Initially the diffuser experienced airflow velocities near zero towards the edges. This led to 0.18% of the mass flow rate occurring in the outer one-fourth portion of the cross-sectional area. With the application of vortex generators, this percentage increased to 5.7%. The 20-degree diffuser improved from 2.5% to 7.9% of the total mass flow rate in the outer portion and the 10-degree diffuser improved from 11.9% to 19.2%. These results demonstrate an increase in performance by the addition of vortex generators while allowing the possibility for further investigation on improvement through the design and configuration of these vortex generators.

Description
The objective of this project was to design an electrically driven centrifugal pump for the Daedalus Astronautics @ASU hybrid rocket engine (HRE). The pump design was purposefully simplified due to time, fabrication, calculation, and capability constraints, which resulted in a lower fidelity design, with the option to be improved later. The impeller, shroud, volute, shaft, motor, and ESC were the main focuses of the pump assembly, but the seals, bearings, lubrication methods, and flow path connections were considered as elements which would require future attention. The resulting pump design is intended to be used on the Daedalus Astronautics HRE test cart for design verification. In the future, trade studies and more detailed analyses should and will be performed before this pump is integrated into the Daedalus Astronautics flight-ready HRE.

Description
Human habitation of other planets requires both cost-effective transportation and low time-of-flight for human passengers and critical supplies. The current methods for interplanetary orbital transfers, such as the Hohmann transfer, require either expensive, high fuel maneuvers or extended space travel. However, by utilizing the high velocities of a super-geosynchronous space elevator, spacecraft released from an apex anchor could achieve interplanetary transfers with minimal Delta V fuel and time of flight requirements. By using Lambert’s Problem and Free Release propagation to determine the minimal fuel transfer from a terrestrial space elevator to Mars under a variety of initial conditions and time-of-flight constraints, this paper demonstrates that the use of a space elevator release can address both needs by dramatically reducing the time-of-flight and the fuel budget.
