In arid environments like Phoenix, many professional and residential outdoor spaces are cooled by the use of misting systems. These systems spray a fine mist of water droplets that cool down the surrounding air through the endothermic evaporation process. When the water droplets evaporate, they leave behind dissolved material that is present in the water, generating ambient particulate matter (PM). Thus, misting systems are a point source of PM. Currently there is no information on their impact on air quality in close proximity to these systems, or on the chemical composition of the particulate matter generated by the evaporating mist.
In this project, PM concentrations are found to increase on average by a factor of 8 from ambient levels in the vicinity of a residential misting system in controlled experiments. PM concentrations in public places that use misting systems are also investigated. The PM10 concentrations in public places ranged from 0.102 ± 0.010 mg m-3 to 1.47 ± 0.15 mg m-3, and PM2.5 ranged from 0.095 ± 0.010 mg m-3 to 0.99 ± 0.10 mg m-3. Air quality index (AQI) values based on these concentrations indicate that these levels of PM range from unhealthy to hazardous in most cases. PM concentrations tend to decrease after remaining relatively constant with increasing distance from misting systems. Chemical data reveal that chloride and magnesium ions may be used as tracers of aerosolized water from misting systems. The average chloride concentration was 71 µg m-3 in misting samples and below the detection limit for Cl- (< 8.2 µg m-3) in ambient samples. The average magnesium concentration was 11.7 µg m-3 in misting samples and 0.23 µg m-3 in ambient samples.

Description
This thesis is exploring the potential disconnect between the operational and cultural parts in the making of sustainability at Arizona State University (ASU) to find the disconnect in operational goals, student engagement, and thus student behavior in building sustainability at the university. To do so, I compare and contrast how ASU, Northern Arizona University (NAU), and the University of Arizona (UA) define, create, and demonstrate sustainability in their university’s culture and campus engagement programs. I first define what “culture” is in this study to provide context on how the word is being applied. Next, I assess how culture is reflected in the mission, vision, and/or goals of each university to set the tone for how the university intends to shape the culture of student experience through its services, as well as provide context where sustainability concepts may fit within. Then I assess what sustainability is demonstrated and defined as at each university. To thread each of these components together, I compare and contrast campus sustainability engagement programs at ASU, NAU, and UA based on the Sustainability Tracking, Assessment and Rating System (STARS) reports produced by The Association for the Advancement of Sustainability in Higher Education’s (AASHE), as engagement programs are a reflection of the university’s vision, goals, and values brought from theory to practice. My findings are demonstrated in the form of a policy analysis, followed by recommendations on closing the gap where engagement programs and opportunities are potentially missing. These recommendations are intended to advance a stronger culture of sustainability on campus at ASU.

Pedagogy and Place: Observations of place-based education in undergraduate sustainability curriculum
Description
As the canonical literature, student competencies and outcomes, and foundational courses of sustainability education are contested and reaffirmed, grounding this academic discipline in an experiential understanding of place is not often asserted as a core aspect of sustainability curriculum. Place can act both as a context and conduit for sustainability education, inspiring student investment in local communities and stewardship of the landscape. Through narrative descriptions of interviews held with professors, program coordinators, and deans from nine sustainability undergraduate programs across the United States, I explore in this thesis how different educators and institutions adopt place-based pedagogy within sustainability curriculum and institutional practice. In observation of these interviews, I name three factors of difference – physical and social setting, academic ethos, and institution size – as axes around which place is incorporated in sustainability instruction and within the college as a whole. Finally, I give general recommendations for incorporating place in sustainability instruction as well as certain creative and place-oriented assignment structures discussed in the interviews.

Description
Climate change, as it becomes more prevalent, is putting a much harsher strain on the resources of the world, specifically food, energy, and water. With this in mind, now is the time to make a change and begin working towards a more sustainable future for everyone. Arizona is an especially susceptible location that has the opportunity to be the leader of this change. In order to effectively manage this movement through governance, a food-energy-water nexus approach is required. This approach recognizes and accounts for the intricate relationships between these industries in order to promote more resilience and balance throughout the nexus. While the main focus in Arizona tends to be on water, and rightfully so, it is important to understand the intricacies of the food, energy, and water systems together. Right now, the system is fragile and needs a new, more complex approach. Ultimately, legislation that intertwines water rights with agriculture regulation and energy production goals, while also including equity and justice measures, have the capacity to work towards limiting the effects of climate change that Arizona will see. Arizona has the opportunity here to either provide a cautionary tale to other regions of how mismanagement can lead to destruction or can showcase the legislative success that the nexus governance approach can provide.

Description
The United States has been facing a resurgence of vaccine preventable infectious diseases. Non-medical vaccination exemptions (NMEs) which include religious exemptions and philosophical vaccine exemptions are contributing factors in state vaccination rates dropping. The policies surrounding such exemptions vary from state to state. Some states with higher rates of nonmedical vaccine exemptions are dealing with repercussions for this including vaccination rates falling below desired herd immunity and thus putting vulnerable populations such as those who are immunocompromised, too young for vaccination and the elderly at a higher risk.
This thesis aims to examine vaccine preventable re-emerging infectious diseases in the United States with the objective of reaching vaccine hesitant populations and providing them with the tools to make informed decisions to seek out immunizations. This will be done by exploring five different diseases and infections, discussing why some individuals feel hesitant to get immunizations, examining how nonmedical vaccine exemptions are correlated to increased cases of disease outbreaks, looking into state laws specifically focused on countering nonmedical vaccine exemptions and the steps that can be taken moving forward.

Description
This thesis conducted an evaluation of the performance and return on investment of a 2 x 6m, simple design greenhouse, as a climate control technology. Specifically, differences in internal microclimate conditions between a greenhouse treatment plot, and sun and shaded control plots were assessed and related to observed differences in crop yields across these plots. Growing conditions and productivity of two crops, tomato and swiss chard, which were grown over summer and winter growing seasons, respectively, were compared. It was found that the greenhouse was associated with improved growth conditions (as measured by the R-Index) for both crops but resulted in higher productivity only for tomatoes. Return on investment and food security impacts from the scaling of greenhouse agriculture were also explored.

Description
This research seeks to identify key influencers on a relatively new type of policy instrument, the Sustainable Purchasing Policy, in the local government context. Specifically, we analyze how vendor relationships and organizational capacity affect perceived Sustainable Purchasing Policy success. Using statistical analysis on a nationally distributed survey to city directors as well as interviews with city purchasing agents, we are able to identify what factors are likely to lead to successful policy implementation. Our findings show that cities benefit from their vendors providing reliable information regarding sustainable offerings, that vendors offering sustainable goods need superior technical capabilities to compete in a cost-driven environment, and that purchasing agents require support from a city’s top management if they want to successfully implement sustainable purchasing. Future avenues for research are discussed.

Description
My creative thesis project was done through a collaborative project with Sustainable Purchasing Leadership Council (SPLC), a non-profit organization whose mission is to support and recognize suppliers and buyers that champion a transition to sustainability-driven value within the purchasing process of corporations and other organizations. Within the SPLC intranet available to members, there is an abundance of guidance to purchasing professionals procuring materials and services required by their organization. This guidance comes in forms such as case studies, example contract language, webinars, green certifications and labels, and various helpful tools. The issue and value add of the project lies in the current organization and location of guidance on the SPLC website. Much of the information is scattered, and many stakeholders have voiced their confusion when seeking guidance on a particular project or process they are undergoing.
Our solution, the “Category Landing Pages” would tackle this issue by re-organizing SPLC’s resources into category specific pages where any and all guidance SPLC has on a particular purchasing category can be easily accessed. Many procurement professionals often specialize and deal in a certain spend or commodity category, which makes a category organized page the most logical. This is certainly valuable to individuals and organizations who subscribe to a membership with SPLC, but there is also opportunity for SPLC to benefit from this restructuring.

Description
There are two main sections of this thesis: Codebook development and case coding. Over the course of my two years of involvement with the collaborative governance lab with Drs. Schoon and Carr Kelman, I worked on helping to complete the coding manual built by the lab to test variables from the literature using case studies. My main deliverable was building a Qualtrics survey to collect case studies. Using this Qualtrics survey, the lab will be able to collect coded cases by distributing the survey link through research networks. My thesis project included building the interface for the survey, participating in testing the intercoder reliability of the codebook, and coding one case, the Four Forest Restoration Initiative (4FRI), to provide insight on the collaborative governance strategies of this collaboration. Coding 4FRI also acted as a preliminary test of the survey, helping to provide further information on how users of the codebook might interact with the survey, and allowing the lab to generate a test report of survey results.

Description
Working in collaboration with the Clark Park Community Garden (CPCG), we sought to identify and implement practices and creative processes that increase community involvement and connection by further transforming the space into a community gathering place. Our primary goal was to foster greater community involvement within the garden through various methods while exploring our own creative outlets to represent what the concepts of “community” and “garden” mean to us.
When initially planning our project, we outlined a research process to conduct interviews with garden participants to determine the best practices for community garden connection-making. However, after our initial discussions with the CPCG Advisory Committee, it became clear that their goals could be better achieved through an applied project focusing on increasing community connection than from a research project. We have adopted our former research question--which asked how community gardens could serve as a means for community connection-- as our premise, and we seek to build upon it through the creation of programs, partnerships, and pieces of art that collectively expand the garden’s connection to its surrounding community. To begin this process, we worked with the leaders of the CPCG to identify the group’s main goals that they sought to achieve with our support. In collaboration with the CPCG Garden Advisory Committee, the three goals that we identified were: 1) increasing neighborhood participation in the space, 2) launching the site’s new subscription program, and 3) transforming the garden space into a place of community.
