As the prevalence of childhood obesity in the United States rises, opportunities for children to be physically active become more vital. One opportunity for physical activity involves children walking to and from school. However, children that live in areas with a pedestrian-unfriendly built environment and a low degree of walkability are less likely to be physically active and more likely to be overweight. The purpose of this study was to study walking routes from schools in low-income neighborhoods in Southwestern United States to a local community center. Walking routes from the three study schools (South Mountain High School, Percy Julian Middle School, and Rose Linda Elementary School) were determined by distance, popularity, and the presence of a major thoroughfare. Segments and intersections, which formed the routes, were randomly selected from each school's buffer region. The walking routes as a whole, along with the segments and intersections, were audited and scored using built environment assessments tools: MAPS, PEQI and Walkability Checklist. These scores were utilized to develop interactive mapping tools to visualize the quality of the routes, segments and intersections and identify areas for improvement. Results showed that the routes from Percy Julian to the Kroc Center were, overall, rated higher than routes from the other two schools. The highest scoring route, from the seven routes studied, was route 2 from Percy Julian to the Kroc Center along Broadway Road. South Mountain High School was overall the worst starting point for walking to the Kroc Center as those three walking routes were graded as the least walkable. Possible areas for improvement include installing traffic calming features along major thoroughfares and reducing the perceived risk to pedestrian safety by beautifying the community by planting greenery. Future directions include studying the built environment in South Phoenix communities that surround the Kroc Center.

The goals of the styrene oxide adsorption experiments were to develop reliable isotherms of styrene oxide onto Dowex Optipore L-493 resin and onto mesoporous carbon adsorbents, in addition to determining the ideal conditions for styrene oxide production from E. coli. Adsorption is an effective means of separation used in industry to separate compounds, often organics from air and water. Styrene oxide adsorption runs without E. coli were conducted at concentrations ranging from 0.15 to 3.00 g/L with resin masses ranging from 0.1 to 0.5 g of Dowex Optipore L-493 and 0.5 to 0.75 g of mesoporous carbon adsorbent. Runs were conducted on a shake plate operating at 80 rpm for 24 hours at ambient temperature. Isotherms were developed from the results and then adsorption experiments with E. coli and L-493 were performed. Runs were conducted at glucose concentrations ranging from 20-40 g/L and resin masses of 0.100 g to 0.800 g. Samples were incubated for 72 hours and styrene oxide production was measured using an HPLC device. Specific loading values reached up to 0.356 g/g for runs without E. coli and nearly 0.003 g of styrene oxide was adsorbed by L-493 during runs with E. coli. Styrene oxide production was most effective at low resin masses and medium glucose concentrations when produced by E. coli.

This paper was born of the researcher's personal interest. As someone who commutes by bike and plans to continue to do so for the foreseeable future, the researcher was intrigued by the growing bicycle culture in Phoenix, Arizona, a city that can sometimes make commuting without a car quite difficult. The researcher aimed to uncover why cycling is becoming more popular as a mode of transportation in a city that can often be hostile towards cyclists. This paper first reviews some previous studies done on alternative commuting. Next, it details a commute-shed analysis conducted with the help of the US Census Bureau's On The Map program. After that, the researcher describes the methods used to gather qualitative data about attitudes from local commuters and discusses the results. Finally, suggestions and speculations are made about ways to improve the bikeability of the Phoenix metropolitan area. The research found that cyclists in the area are motivated to commute by bike by factors including cost-savings, health benefits, and others. This data is important because it shows that the target demographic, who are able to exert their desires politically, feel strongly enough about commuting by bicycle to go out of their way to do it.

Metal-organic frameworks (MOFs) are a new set of porous materials comprised of metals or metal clusters bonded together in a coordination system by organic linkers. They are becoming popular for gas separations due to their abilities to be tailored toward specific applications. Zirconium MOFs in particular are known for their high stability under standard temperature and pressure due to the strength of the Zirconium-Oxygen coordination bond. However, the acid modulator needed to ensure long range order of the product also prevents complete linker deprotonation. This leads to a powder product that cannot easily be incorporated into continuous MOF membranes. This study therefore implemented a new bi-phase synthesis technique with a deprotonating agent to achieve intergrowth in UiO-66 membranes. Crystal intergrowth will allow for effective gas separations and future permeation testing. During experimentation, successful intergrown UiO-66 membranes were synthesized and characterized. The degree of intergrowth and crystal orientations varied with changing deprotonating agent concentration, modulator concentration, and ligand:modulator ratios. Further studies will focus on achieving the same results on porous substrates.

Food insecure populations suffer from the ability to access affordable and nutritious foods as a result of financial and transportation needs. Often these populations are concentrated in areas referenced as food deserts. A food desert is an area that does not have a supermarket or large grocery store within a mile and often is saturated with small non-traditional food stores and fast- food establishments. In this study, 21 food deserts along Grand Avenue in Downtown Phoenix were analyzed to better understand their access to food, population statistics and barriers to being food secure. The research question analyzed is the impact food insecurity has on communities in Phoenix, Arizona. The findings are presented in the form of a research paper, as well as 15 black and white film photographs accompanied by descriptions. There is primary qualitative data presented through photographs and observations, as well as secondary quantitative data analyzed from Census data. The food deserts studied consist of communities that are low-income and majority minority with little to no access to nutritious food in their area. The economics of food insecurity and grocery stores, racial discrimination, access to transportation, impacts on health and education and the sustainability of food deserts are all aspects of food insecurity discussed in the research. Possible solutions such as community gardens and subsidized grocery stores are also presented. The study revealed that food insecurity has several negative impacts on the affected populations and communities and disproportionately impacts low-income and minority communities.

Golf courses require large amounts of water and other resources. The Southwestern United States has experienced rapid population growth, coupled with a dramatic increase in the built environment and golf courses. This paper aims to assess the environmental sustainability of golf courses in the Phoenix Metropolitan area at multiple scales in terms of water, ecosystem services and management practices. We report on the number and spatial distribution of golf courses, the amount of water used by them, the ecosystem services they provide, potential social injustice issues within the area, and the sustainability of management practices. There are 197 golf courses within the Phoenix Metropolitan Area, which are composed of 465 patches covering an area around 57 square miles. The golf courses within the Phoenix Active Management Area use around 500 acre-feet of water per year. Golf courses are categorized as an industrial water user and account for roughly half of all industrial water use in the Phoenix Active Management Area. The primary water source for golf courses is groundwater, with effluent as their second most-used source. Most golf courses are located in areas with a median household income between $61,333-$90,185 and only one was located in an area with a median household income below $27,393. Golf courses in the region provide a number of ecosystem services and help the local economy in multiple ways. However, given the scarcity of water and the projected drier and hotter climate in the American Southwest, we suggest curbing the expansion of golf courses and implement more sustainable management practices.

Urban Ecological Infrastructure (UEI) increases landscape sustainability by meeting multiple socioeconomic and environmental objectives. Community parks are a common form of green or terrestrial UEI that improve access to open space in urban areas. They also provide environmental benefits such as increased biodiversity, pollution filtration, urban heat island mitigation, and rainwater drainage. Decision-makers should consider these factors when siting parks to maximize services, especially since land acquisition involves budget constraints. Geographic information systems (GIS) include various tools that can be used to site parks based on multiple spatial datasets. This research develops a GIS process to identify suitable parcels for parks, filling a gap in the literature through developing a small-scale analysis that considers local context and includes smaller pockets of potential green space in Metro Phoenix, Arizona. This process involved compiling a dataset of socioeconomic and environmental criteria, creating park suitability layers in ArcGIS Pro, and conducting statistical and spatial analyses on the suitability layers. The analysis involved assigning scores to each parcel, where higher scores indicate higher park suitability, and lower scores indicate lower park suitability. Factors that resulted in higher suitability scores were barren land cover, low tree canopy, high surface temperature, in a flood zone, far from existing parks and trails, high percentage of minority and low-income residents, and in an urban area. The resulting maps show significantly higher scores in the southern and western parts of Maricopa County, particularly in and around Gila Bend. While most high-ranking parcels are situated along rural highways, there are many large clusters of high-ranking urban parcels along waterways in Metro Phoenix. Based on this assessment, I recommend park implementation efforts focus on land along the Salt River, Gila River, and Agua Fria River in southern and western Phoenix. Further research could build on this methodology, integrating additional datasets such as walkability scores and experimenting with the parameters to see how the results change.

This thesis explores conservation of threatened and endangered species in the Phoenix metro area using social media. With increased urbanization, rising temperatures, and other issues occurring in the desert landscape, creatures big and small face devastating losses in their populations. Informing the public about the species currently on the brink of extinction allows people to identify the animals in the wild, and may encourage conservation practices that would allow wildlife to thrive far into the future. Utilizing social media as a tool for spreading awareness permits information about Arizona wildlife to be free and easily accessible. This project consists of interviews with conservationists and social media influencers, a survey to understand online behaviors and identify level of interest in the different species, and the creation of consumable social media infographics about the threatened and endangered species of Phoenix. Instagram was selected by survey respondents as the platform they would follow conservation accounts on, leading to the creation of @phxconservation to post the social media infographics. Best practices found by posting on social media in this project can be useful information for conservationists looking to build engagement and effectively inform people.

The following paper is a comparison between the Mercato di Sant’Ambrogio (Sant’Ambrogio Market) in Florence, Italy and the Open Air Farmers’ Market in Phoenix, Arizona. Farmers’ markets, such as these, serve to rekindle a relationship with food that over time has been lost, particularly due to the green revolution, globalisation, and the mechanization of agriculture. In addition, farmers’ markets serve to foster relationships between community members and farmers, and they are an important element of a movement to create food sovereignty within local communities. Food sovereignty gives people the right to decide their food choices. In our modern system where many agricultural decisions are made by the government or large corporations, reclaiming food sovereignty is a larger effort to take back control of personal rights, individual health and the health of the environment.
Using Sant’Ambrogio and Open Air as case studies for the research, this paper provides insight on the degree of impact that local farmers’ markets can have on creating food sovereignty within communities; and how pre-existing factors and negative forces diminish the benefits of farmers’ markets and local food movements. Among many, some of these negative forces include the effects of social and cultural pressures that promote fast food and convenience; a broken agricultural system controlled by monopoly companies; industrial food items priced cheaper than small farmers can compete with; and an underscore of unethical behavior across all sectors (including organic and local) that inhibit honest farmers from making enough profit to survive.
The comparison between Sant’Ambrogio and Open Air Market indicates that big agriculture undermines the success of local farming movements in both countries, but Phoenix can still learn from the movement in Florence, which is rooted in a deep history of outdoor markets and rich food culture. Italy is fortunate in terms of their agriculture capacity because their climate allows for a diverse variety of crops; while Arizona does not have the same agricultural capacity as the Mediterranean climate of Italy, it is still valuable to mimic the network of local food systems that Italy has. In order to do so, Phoenician consumers should take advantage of the food that grows locally and then supplement it with more diverse crops from other areas of Arizona or the southwest.
The Open Air Market in Phoenix currently does not play an important role in the food system except for helping people to relate community and socialization to food. Transparency, communication and education are required to actually increase the success of small local farmers and to help the Open Air Market play a real role in the local food movement and the establishment of food sovereignty.

Phoenix, Arizona is a city characterized by intense urban sprawl: low-density, spread out, and disconnected development. Within the Phoenix Metropolitan Area comes a new development, Culdesac, that creates car-free living geared towards alternate transit methods. This new neighborhood offers a more sustainable urban form that contrasts Phoenix and has potential to increase walkability in the city. After examining case studies of Vauban, Germany; Masdar City, Abu Dhabi; and Fruitvale, California as examples of sustainable development with a focus on alternate transit, this paper compares these examples to the future of Culdesac. A list of principles of walkability including public participation, scale, creativity, adherence to principles, government cooperation, and transportation help to guide this comparison and determine whether Culdesac is a possible method to increase sustainable urban form in the Phoenix Metropolitan Area.
