This study examines the spatial and temporal patterns of the surface urban heat island (SUHI) intensity in the Phoenix metropolitan area and the relationship with land use land cover (LULC) change between 2000 and 2014. The objective is to identify specific regions in Phoenix that have been increasingly heated and cooled to further understand how LULC change influences the SUHI intensity. The data employed include MODerate-resolution Imaging Spectroradiometer (MODIS) land surface temperature (LST) 8-day composite June imagery, and classified LULC maps generated using 2000 and 2014 Landsat imagery. Results show that the regions that experienced the most significant LST changes during the study period are primarily on the outskirts of the Phoenix metropolitan area for both daytime and nighttime. The conversion to urban, residential, and impervious surfaces from all other LULC types has been identified as the primary cause of the UHI effect in Phoenix. Vegetation cover has been shown to significantly lower LST for both daytime and nighttime due to its strong cooling effect by producing more latent heat flux and less sensible heat flux. We suggest that urban planners, decision-makers, and city managers formulate new policies and regulations that encourage residential, commercial, and industrial developers to include more vegetation when planning new construction.

Collaborative research is not only a form of social and human capital and a public good, but also a fundamental elicitor of positive Collective Action. Collaborative Research Networks can serve as models of proactive and purposive Collective Action and catalysts of societal change, if they function as more than hubs of research and knowledge. It is the goal of this Honors Thesis to examine the current nature under which collaborative research networks, focused on matters of Global Health or Sustainability, operate., how they are organized, what type of collaboration they engage in, and who collaborates with whom. A better understanding of these types of networks can lead to the formation of more effective networks that can develop innovative solutions to our collective Global Health and Sustainability problems.

This paper studies the effect of targeted observations on state and parameter estimates determined with Kalman filter data assimilation (DA) techniques. We first provide an analytical result demonstrating that targeting observations within the Kalman filter for a linear model can significantly reduce state estimation error as opposed to fixed or randomly located observations. We next conduct observing system simulation experiments for a chaotic model of meteorological interest, where we demonstrate that the local ensemble transform Kalman filter (LETKF) with targeted observations based on largest ensemble variance is skillful in providing more accurate state estimates than the LETKF with randomly located observations. Additionally, we find that a hybrid ensemble Kalman filter parameter estimation method accurately updates model parameters within the targeted observation context to further improve state estimation.

Spasticity is a neurological disorder in which a target group of muscles remain in a contracted state. In addition to interfering with the function of these muscles, spasticity causes chronic pain and discomfort. Often found in patients with cerebral palsy, multiple sclerosis, or stroke history, spasticity affects an estimated twelve million people worldwide. Not only does spasticity cause discomfort and loss of function, but the condition can lead to contractures, or permanent shortenings of the muscle and connective tissue, if left untreated. Current treatments for spasticity are primarily different forms of muscle relaxant pharmaceuticals. Almost all of these drugs, however, carry unwanted side effects, including total muscle weakness, liver toxicity, and possible dependence. Additionally, kinesiotherapy, conducted by physical therapists at rehabilitation clinics, is often prescribed to people suffering from spasticity. Since kinesiotherapy requires frequent practice to be effective, proper treatment requires constant professional care and clinic appointments, discouraging patient compliance. Consequently, a medical device that could automate relief for spasticity outside of a clinic is desired in the market. While a number of different dynamic splints for hand spasticity are currently on the market, research has shown that these devices, which simply brace the hand in an extended position, do not work through any mechanism to decrease spastic tension over time. Two methods of temporarily reducing spasticity that have been observed in clinical studies are cryotherapy, or the decrease of temperature on a target area, and electrotherapy, which is the delivery of regulated electrical pulses to a target area. It is possible that either of these mechanisms could be incorporated into a medical device aimed toward spastic relief. In fact, electrotherapy is used in a current market device called the SaeboStim, which is advertised to help stroke recovery and spastic reduction. The purpose of this paper is to evaluate the viability of a potential spastic relief device that utilizes cryotherapy to a current and closest competitor, the SaeboStim. The effectiveness of each device in relieving spasticity is reviewed. The two devices are also compared on their ability to address primary customer needs, such as convenience, ease of use, durability, and price. Overall, it is concluded that the cryotherapy device more effectively relieves hand spasticity in users, although the SaeboStim's smaller size and better convenience gives it market appeal, and reveals some of the shortcomings in the preliminary design of the cryotherapy device.

Description
Regardless of religious beliefs, all one has left when they leave this Earth is the meaning the individual has derived from building connections and relationships with other people. I propose whether or not one is able to reach his or her potential and the quality of life that follows is based inherently in the following question: How will you manifest your truth into reality, thus becoming the best at your profession or craft, and spreading your gifts to help the lives of others? The answer to this question, and ultimately the key to leading the best life available is in the equation: vulnerability through playfulness and connection instigates happiness, which results in spreading positivity and facilitating the ability to make fearless decisions that guides one's life as an artist or profession of one's choosing, leading one to their highest potential. This theory applies to everyone and does not discriminate. This is the beginning of a life-long exploration and discovery with these elements as I further my work as an artist, and I will explore these themes from my exposure to the Balinese people and culture, our theatre workshops and experiences there, and through additional inspiration and research. The workshop and clowning in Bali training helped form the theory I have proposed, and further introduced a different approach to acting that I utilize in my own work that incorporates taksu: an achievable state of being that is unanimously understood by the Balinese that influences and shapes how they approach life, work, and each other that I discuss more extensively in my work. I will continue to inquire about how one finds space for imagination and pursuit of taksu without traveling, although traveling is an amazing way to broaden one's scope of perspective. The combination of elements discussed and taksu help create a humanity that is more in touch with inner peace and happiness as a result of spreading both positivity and a positive mindset to others. This in turn, influences and shapes performance and how we approach the craft of acting, while creating emotional truth and integrity within one's craft.

Description
Arizona State University and Banner Thunderbird Hospital have partnered to provide pre-med students with an internship at a local emergency department. Students entering into this program will have access to each patient's vital signs, medical imaging, lab tests, and medications. This access presents students with an opportunity to learn about a variety of tools used in the assessment and treatment of emergency room patients. In order to enhance the amount of knowledge students take away from the program, I created a handbook summarizing a variety of diagnostic tests and medications. The first section of the handbook (assessment) is spilt up into the three following categories: vital signs, medical imaging, and lab tests. The second section (treatment) consists of one category, medications. Each section was written with emphasis on basic physiology, and is intended to provide pre-med students with a foundation for building further medical knowledge. Although this handbook was tailored to the information students are most likely to encounter working in Banner Thunderbird Hospital's emergency department, it is still appropriate for any student interested in learning about emergency medicine.

Description
This creative group project aims to bring visibility to the diversity of the LGBTQ+ community at Arizona State University by sharing the personal stories and opinions of people from across ASU's rainbow spectrum. Created and produced by a gay couple that met in their first year dorm and a passionate ally, gAySU: Exploring Sparky's Rainbow is a compilation of photos, videos, and stories from ASU students, faculty, and staff that identify with the LGBTQ+ community. When reflecting on their own journey over the past three years, gAySU's creators recognized ASU can feel large with many pockets of communities, yet through trial and error over the past 4 years they managed to explore their identities and grow as individuals, as a couple, and as an ally. By sharing their story and the stories of others, it is the hope that gAySU allows its readers and viewers an insight into what it means to be both a Sun Devil and LGBTQ+, and for those new to or anxious to identify with the LGBTQ+ community, to understand they are not alone in their journey and that it is okay to bleed maroon, gold, and all other colors of the rainbow.

This thesis explores the various reasons that Broadway musicals fail, or "flop". It goes into detail on several musicals of different genres, and explains what their shortcomings were, whether it be a less-than-perfect book, a weak score, or a production team that was not experienced in the skills that it takes to put together a musical. It discusses how long the shows ran for, or if they ever made it into a Broadway house. It looks at what the audience reception was like for each show, and whether the shows were a success with the tough critics of Broadway. In addition to this, I have recorded several of my peers performing songs from the musicals I have discussed in the written portion of this thesis. This helps to educate an audience on what it would have been like for one of the flop's real performances. The videos also do a wonderful job of communicating what the show sounds like, and how it can make an audience feel or react. Lastly, it gives more insight into why the musicals they are from failed to thrive in front of a Broadway audience. Through my research, I have discovered that creating a musical is possibly one of the most difficult feats a team of creative people can accomplish. There are countless reasons for failure in these shows, but overall, I feel that every failure had something to offer, and because of that, are surely worth celebrating.

Description
Studies on urban heat island (UHI) have been more than a century after the phenomenon was first discovered in the early 1800s. UHI emerges as the source of many urban environmental problems and exacerbates the living environment in cities. Under the challenges of increasing urbanization and future climate changes, there is a pressing need for sustainable adaptation/mitigation strategies for UHI effects, one popular option being the use of reflective materials. While it is introduced as one effective method to reduce temperature and energy consumption in cities, its impacts on multi-dimensional environmental sustainability and large-scale non-local effect are inadequately explored. This paper provides a synthetic overview of potential environmental impacts of reflective materials at a variety of scales, ranging from energy load on a single building to regional hydroclimate. The review shows that mitigation potential of reflective materials depends on a portfolio of factors, including building characteristics, urban environment, meteorological and geographical conditions, to name a few. Precaution needs to be exercised by city planners and policy makers for large-scale deployment of reflective materials before their environmental impacts, especially on regional hydroclimates, are better understood. In general, it is recommended that optimal strategy for UHI needs to be determined on a city-by-city basis, rather than adopting a “one-solution-fits-all” strategy.
