Description
The study examines cross-cultural perceptions of wastewater reuse from 282 participants from four global sites representing varied levels of socio-economic and political development from the Global North and Global South: Spain, New Zealand, Fiji, and Guatemala. The data comes from the Global Ethnohydrology Survey conducted by the School of Human Evolution and Social Change during the summer of 2013. The Global Ethnohydrology Study is a transdisciplinary multi-year research initiative that examines the range of variation in local ecological knowledge of water issues, also known as "ethnohydrology." Participants were asked about their willingness, level of disgust, and concern with using treated wastewater for various daily activities. Additionally, they were asked to draw schematic representations of how wastewater should be treated to become drinkable again. Using visual content analysis, the drawings were coded for a variety of treatment levels and specific treatment processes. Conclusions about the perceived health implications from wastewater reuse that can stem from drinking treated wastewater were made. The relationship between humans and wastewater is one that has many direct social and health impacts on communities at large. In reaction to global limitations of freshwater, wastewater serves as a valuable resource to tap into. This research examines the cross-cultural public health concerns about treated wastewater in order to draw conclusions that can aid in strategic implementation of advocacy and public education about wastewater reuse.

Description
Children's drawings are increasingly being used to assess understanding and diagnose misconceptions about water issues and the environment. As part of Arizona State University's Global Ethnohydrology Study and Community Health and Medical Anthropology Field School, 315 pieces of artwork from 158 Guatemalan schoolchildren, ages 9-10, were collected using ethnographic field methods. The children were asked to draw two pieces of art: one showing how they saw water being used in their neighborhood today and one showing how they imagined water would be used in their neighborhood 100 years from now. Using visual content analysis, the drawings were coded for the presence of vegetation, scarcity, pollution, commercial sources, existing technology, technological innovation, domestic use, and natural sources of water. The study finds that (1) students' drawings of the future contain significantly more pollution and scarcity than those in the present, and (2) both boys and girls depict existing technology significantly more often in the drawings of today than the drawings of the future. Additionally, (1) boys are significantly more likely than girls to draw more negative depictions of water (i.e., pollution and scarcity), and (2) boys are significantly more likely than girls to depict the natural world (i.e., natural sources of water). Through examining gendered perceptions and future expectations of climate change and water issues, this study explores possible areas of intervention in environmental education in a developing country.

Description
The influenza virus, also known as "the flu", is an infectious disease that has constantly affected the health of humanity. There is currently no known cure for Influenza. The Center for Innovations in Medicine at the Biodesign Institute located on campus at Arizona State University has been developing synbodies as a possible Influenza therapeutic. Specifically, at CIM, we have attempted to design these initial synbodies to target the entire Influenza virus and preliminary data leads us to believe that these synbodies target Nucleoprotein (NP). Given that the synbody targets NP, the penetration of cells via synbody should also occur. Then by Western Blot analysis we evaluated for the diminution of NP level in treated cells versus untreated cells. The focus of my honors thesis is to explore how synthetic antibodies can potentially inhibit replication of the Influenza (H1N1) A/Puerto Rico/8/34 strain so that a therapeutic can be developed. A high affinity synbody for Influenza can be utilized to test for inhibition of Influenza as shown by preliminary data. The 5-5-3819 synthetic antibody's internalization in live cells was visualized with Madin-Darby Kidney Cells under a Confocal Microscope. Then by Western Blot analysis we evaluated for the diminution of NP level in treated cells versus untreated cells. Expression of NP over 8 hours time was analyzed via Western Blot Analysis, which showed NP accumulation was retarded in synbody treated cells. The data obtained from my honors thesis and preliminary data provided suggest that the synthetic antibody penetrates live cells and targets NP. The results of my thesis presents valuable information that can be utilized by other researchers so that future experiments can be performed, eventually leading to the creation of a more effective therapeutic for influenza.

Description
In this project we examine the geographical availability of water resources for persons experiencing homelessness in Phoenix, Arizona, U.S.A. Persons experiencing homelessness spend a significant portion of their time outdoors and as such have a higher risk of dehydration, heat-related illness, and heat stress. Our data was collected using archival data, participant- observation, focal follows with water distributors that serve homeless populations, phone and internet surveys with social service providers, and expert interviews with 14 local service providers. We analyzed this data using methods for thematic coding and geospatial analysis. We find that the sources of water and geographic availability vary across the economic sectors of the population and that they become more unconventional and more difficult to access with further isolation. We conclude that many persons who are experience homelessness have inconsistent and unreliable access to water for hydrating, maintaining hygiene, cooking and cleaning for reasons that are largely due to geographic inaccessibility.

Description
The Culture, Health, and Environment Lab (CHEL) at Arizona State University uses anthropological methods and field-based studies to research how cultural knowledge may be used to help understand and respond to contemporary environmental and health issues—primarily the global challenges of water insecurity and obesity. In their efforts to research water insecurity and it implications, CHEL has been working on studying water insecurity through the Global Ethnohydrology Study (GES). The Global Ethnohydrology study examines local knowledge and perceptions of water issues, using transdisciplinary methods in a multi-year and cross-country program. In the 2015-2016 study, the GES examined water, hygiene norms, and hygiene stigma. It sought to investigate how hygiene norms are impacted by the level of water security, examining if water-poor communities have laxer laxer or more accommodating hygiene norms. This paper will explore the development of the codebook for this study, following the process in which the qualitative data from the GES 2015 was organized through a series of codes so that it may later be analyzed.

Description
Advancements in both the medical field and public health have substantially minimized the detrimental impact of infectious diseases. Health education and disease prevention remains a vital tool to maintain and propagate this success. In order to determine the relationship between knowledge of disease and reported preventative behavior 180 participants amongst the ASU student population were surveyed about their knowledge and prevention behavior for 10 infectious diseases. Of the 180 participants only 138 were completed surveys and used for analysis. No correlation was found between knowledge or perceived risk and preventative measures within the total sample of 138 respondents, however there was a correlation found within Lyme disease and Giardia exposure to information and prevention. Additionally, a cultural consensus analysis was used to compare the data of 17 US-born and 17 foreign-born participants to analyze patterns of variation and agreement on disease education based on national origins. Cultural consensus analysis showed a strong model of agreement among all participants as well as within the US-born and foreign-born student groups. There was a model of agreement within the questions pertaining to transmission and symptoms. There was not however a model of agreement within treatment questions. The findings suggest that accurate knowledge on infectious diseases may be less impactful on preventative behavior than social expectations.

Environmental releases of neonicotinoid and fipronil insecticides via U.S. wastewater infrastructure
Description
This dissertation is focused on environmental releases from U.S. wastewater infrastructure of recently introduced, mass-produced insecticides, namely neonicotinoids as well as fipronil and its major degradates (sulfone, sulfide, amide, and desulfinyl derivatives), jointly known as fiproles. Both groups of compounds recently have caught the attention of regulatory agencies worldwide due to their toxic effects on pollinators and on aquatic invertebrates at very low, part-per-trillion levels (Chapter 1). Mass balance studies conducted for 13 U.S. wastewater treatment plants (WWTPs) showed ubiquitous occurrence (3-666 ng/L) and persistence of neonicotinoids (Chapter 2). For the years 2001 through 2016, a longitudinal nationwide study was conducted on the occurrence of fiproles, via analysis of sludge as well as raw and treated wastewater samples. Sludge analysis revealed ubiquitous fiprole occurrence since 2001 (0.2-385 µg/kg dry weight) and a significant increase (2.4±0.3-fold; p<0.005) to elevated levels found both in 2006/7 and 2015/6. This study established a marked persistence of fiproles during both wastewater and sludge treatment, while also identifying non-agricultural uses as a major source of fiprole loading to wastewater (Chapter 3). Eight WWTPs were monitored in Northern California to assess pesticide inputs into San Francisco Bay from wastewater discharge. Per-capita-contaminant-loading calculations identified flea and tick control agents for use on pets as a previously underappreciated source term dominating the mass loading of insecticides to WWTPs in sewage and to the Bay in treated wastewater (Chapter 4). A nationwide assessment of fipronil emissions revealed that pet products, while representing only 22±7% of total fipronil usage (2011-2015), accounted for 86±5% of the mass loading to U.S. surface waters (Chapter 5). In summary, the root cause for considerable annual discharges into U.S. surface waters of the neonicotinoid imidacloprid (3,700-5,500 kg/y) and of fipronil related compounds (1,600-2,400 kg/y) is domestic rather than agricultural insecticide use. Reclaimed effluent from U.S. WWTPs contained insecticide levels that exceed toxicity benchmarks for sensitive aquatic invertebrates in 83% of cases for imidacloprid and in 67% of cases for fipronil. Recommendations are provided on how to limit toxic inputs in the future.

Description
The Science of Water Art project is a collaborative work that brings together professionals, community members, college students and children to think about the role that water plays in each of our lives. Using a sample of 4th grade classrooms in Maricopa County, over 3000 drawings of children's perception of water today and in the future were collected. The 9-11 year olds were asked to draw pictures of 1) how they saw water being used in their neighborhood today (T1), and 2) how they imagined water would be used in their neighborhood 100 years from now (T2). The artwork was collected and coded for nine different themes, including: vegetation, scarcity, pollution, commercial sources of water, existing technology, technology innovation, recreational use, domestic use, and natural sources of water. Statistically significant differences were found between boys and girls for vegetation, technology and domestic use themes. This project allows for a look into how climate change and water insecurity is viewed by younger generations and gives a voice to children so that they may share their outlooks on this vital resource.

Description
Agriculture is the second largest water consumer in the Phoenix Metropolitan region, after the municipal sector. A significant portion of the cultivated land and agricultural water demand is from the production of animal feed, including alfalfa (~69% of total cropland area), corn (~8), and sorghum (-3%), which are both exported and needed to support local dairy industry. The goal of this thesis is to evaluate the impacts on water demand and crop production of four different crop portfolios using alfalfa, corn, sorghum, and feed barley. For this aim, the Water Evaluation And Planning (WEAP) platform and the embedded MABIA agronomic module are applied to the Phoenix Active Management Area (AMA), a political/hydrological region including most of Phoenix Metro. The simulations indicate that the most efficient solution is a portfolio where all study crop production is made up by sorghum, with an increase of 153% in crop yield and a reduction of 60% of water consumption compared to current conditions. In contrast, a portfolio where all study crop production is made up by alfalfa, which is primary crop grown in current conditions, decreased crop yield by 77% and increases water demand by 105%. Solutions where all study crop production is achieved with corn or feed barley lead to a reduction of 77% and 65% of each respective water demand, with a portfolio of all corn for study crop production increasing crop yield by 245% and a portfolio of all feed barley for study crop production reducing crop yield by 29%.

Description
The monsoon season is an important part of Arizona's ecosystem as it provides 33% of Maricopa's annual rainfall. However, the monsoon also brings storms with high rainfall intensity which can cause floods. As Maricopa continues to expand and become more urbanized, it may become more susceptible to flooding. This project analyzes watersheds across Maricopa County to determine the amount of runoff that occurs for a given rainfall event.
