Description
The National Research Council 2011 report lists quantifying the extent of de facto (or unplanned) potable reuse in the U.S. as the top research need associated with assessing the potential for expanding the nations water supply through reuse of municipal wastewater. Efforts to identify the significance and potential health impacts of de facto water reuse are impeded by out dated information regarding the contribution of municipal wastewater effluent to potable water supplies. This project aims to answer this research need. The overall goal of the this project is to quantify the extent of de facto reuse by developing a model that estimates the amount of wastewater effluent that is present within drinking water treatment plants; and to use the model in conjunction with a survey to help assess public perceptions. The four-step approach to accomplish this goal includes: (1) creating a GIS-based model coupled with Python programming; (2) validating the model with field studies by analyzing sucralose as a wastewater tracer; (3) estimating the percentage of wastewater in raw drinking water sources under varying streamflow conditions; (4) and assessing through a social survey the perceptions of the general public relating to acceptance and occurrence of de facto reuse. The resulting De Facto Reuse in our Nations Consumable Supply (DRINCS) Model, estimates that treated municipal wastewater is present at nearly 50% of drinking water treatment plant intake sites serving greater than 10,000 people (N=2,056). Contrary to the high frequency of occurrence, the magnitude of occurrence is relatively low with 50% of impacted intakes yielding less than 1% de facto reuse under average streamflow conditions. Model estimates increase under low flow conditions (modeled by Q95), in several cases treated wastewater makes up 100% of the water supply. De facto reuse occurs at levels that surpass what is publically perceived in the three cities of Atlanta, GA, Philadelphia, PA, and Phoenix, AZ. Respondents with knowledge of de facto reuse occurrence are 10 times more likely to have a high acceptance (greater than 75%) of treated wastewater at their home tap.

Description
While women in higher income countries can expect to survive a diagnosis of breast cancer, women in lower- and middle-income countries such as Bangladesh have mortality rates near 50%, suggesting that there are significant barriers to care seeking for breast problems. Given limited literature on barriers to care among native, rural South Asian populations, this study thus sought to understand 1) the impacts of breast problems on women and their families, including the extent of abuse among women with breast problems, and 2) the barriers and facilitators of care for women with breast problems in rural Bangladesh.
Sixty-three study participants (43 women and 20 men) were interviewed about their experiences. Interviewers elicited barriers to care, facilitators of care, and questions about the attitudes and behaviors of family and community members were in structured interviews.
The study found that breast problems and their treatment put significant resource and emotional strains on the family. Furthermore, over a third of women in this study reported abuse of some kind, with emotional abuse, neglect, and abandonment being the most frequently reported.
The study reinforced barriers to care identified in the literature for South Asian populations, but only a quarter of participants reported stigma of any kind. Lack of knowledge about breast cancer and inability to pay for care were the most frequently reported barriers, followed by access to care and fear of treatment. Facilitators of care among women who received a biopsy point to the importance of support by the husband and husband’s family, as well as the ability to identify economic support for and knowledge about care.
This study contributes to the understanding of two overarching themes: structural violence and the value of women, as well as how these themes influence poor outcomes for women with breast cancer in rural Bangladesh. Suggestions for future studies and short and long-term interventions to address study findings are offered.

Description
The worldwide supply of potable fresh water is ever decreasing. While 2.5% of Earth's water is fresh, only 1% is accessible. Of this water, the World Health Organization estimates that only one-third can be used to meet our daily needs while the other two-thirds are unusable due to contamination. As the world population continues to grow and climate change reduces water security, we must consider not only solutions, but evaluate the perceptions and reactions of individuals in order to successfully implement such solutions. To that end, the goal of this dissertation is to explore human attitudes, beliefs, and behaviors around water issues by conducting cross-cultural comparisons of (1) water risks and solutions, (2) wastewater knowledge and acceptance, and (3) motivators for willingness to use treated wastewater. Previous research in these domains has primarily focused on a single site or national context. While such research is valuable for establishing how and why cultural context matters, comparative studies are also needed to help link perceptions at local and global scales. Adopting an interdisciplinary approach grounded in anthropological methods and theory, I use interview data collected in a range of international sites as part of the Arizona State University's Global Ethnohydrology Study. With funding from National Science Foundation grants to the Decision Center for a Desert City (DCDC) and the Central Arizona-Phoenix Long-Term Ecological Research project (CAP LTER), this dissertation explores cross-cultural perceptions of water threats and management strategies, specifically wastewater reclamation and reuse, in order to make recommendations for policy makers and water managers.

Description
There is an enormous unmet need for services, education, and outreach to improve women’s breast health. Healthcare systems and insurance systems vary widely around the world, and this may play an important role in understanding variability in women’s breast health knowledge and behavior globally. The goal of this study is to determine how varying healthcare systems in three countries (Japan, Paraguay, US) affect a woman’s likelihood of seeing a physician in regard to their breasts. For example, Japan is a clear example of a region that provides universal health insurance to its citizens. The government takes responsibility in giving accessible and equitable healthcare to its entire population (Zhang & Oyama, 2016). On the other hand, a country such as Paraguay is composed of both public and private sectors. In order for citizens to gain insurance, one would have to either be formally employed or choose to pay out-of-pocket for hospital visits (“Paraguay”, 2017). A country such as the United States does not have universal health insurance. However, it does have a mix of public and private sectors, meaning there is little to no coverage for its citizens. To accommodate for this, the United States came up with the Affordable Care Act, which extends coverage to the uninsured. Although the United States might be a country that spends more on healthcare than any other nation, there are residents that still lack healthcare (De Lew, Greenberg & Kinchen, 1992). This study, then, compares women’s breast health knowledge and behavior in Japan, Paraguay, and the US. Other variables, which are also considered in this study, that might affect this include wealth level, education, having general awareness of breast cancer, having regular health checks, and having some breast education. Using statistical analysis of breast check rates of women in Japan, Paraguay, and the United States, this research found that women sampled in Asunción, Paraguay check their breasts more often than either women sampled from Scottsdale, U.S. or Osaka, Japan. It was also found that women sampled from Paraguay were more confident in detecting changes in their breast compared to women sampled from the Japan or the US. Finally, it was noted that women sampled from Japan were least likely to partake in seeing a doctor in concern of changes in their breasts compared to women sampled from the other two research locations. These findings have relevance for the implementation of advocacy and public education about breast health.
