Barrett, The Honors College Thesis/Creative Project Collection
Barrett, The Honors College at Arizona State University proudly showcases the work of undergraduate honors students by sharing this collection exclusively with the ASU community.
Barrett accepts high performing, academically engaged undergraduate students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project which is an opportunity to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is supervised and defended in front of a faculty committee. Students are able to engage with professors who are nationally recognized in their fields and committed to working with honors students. Completing a Barrett thesis or creative project is an opportunity for undergraduate honors students to contribute to the ASU academic community in a meaningful way.

Description
Minority women continue to be underrepresented in STEM fields and in STEM related degrees, leading to a lack of diversity in the research conducted and voices advocated for in STEM. To understand why there continues to be a lack of representation of minority women in STEM, I conducted a survey of approximately 20 high school girls who identified as minorities and had an interest in science and conservation to ask questions about their hesitancy to attend college and the different barriers they face. The results of this survey show that these minority girls have low hesitancy when considering applying to and attending college. The biggest barrier these girls face is cost, with 74% of respondents citing college expense as a source of hesitancy when considering applying to college. I then discuss possible interventions that would lead to an increase in the representation of minority women in STEM in higher education. I suggest that colleges and universities should highlight scholarships, financial aid, and programs available and that minority women are eligible for, or they should reduce the cost of tuition.

Description
Ground-motion data from the February 6th, 2023 Kahmaranmaraş, Türkiye earthquake sequence is analyzed. Acceleration and deformation response spectra are analyzed to predict susceptible infrastructure and failure mechanisms of reinforced concrete structures in the region. Images are used to compare the theoretical failure and actual building failures in the region. Recommendations are provided for both the seismic design code and seismic retrofitting.

Description
Best Management Practices (BMPs) are often designed to restore the water quality of impaired waterbodies. They are expensive to install and maintain and often have limited post-installation analysis. There is a gap in our knowledge of the long-term real-world efficiency of such systems as their dynamics are complex and poorly understood, and we have very limited data about these systems. We looked at water quality changes pre- and post-BMP implementation from sites around the US to better understand the impacts of BMPs on the nitrogen (N) and phosphorus (P) concentrations in the waterbodies. Water quality data was obtained from 72 waterbodies across the United States using the National Water Quality Monitoring Council’s Water Quality Portal. This data was analyzed for trends using the Kaplan-Meier method, exceedance probability, and lag time analysis. Out of the seventy-two (72) watershed locations, twenty-two (22) did not have enough data for analysis. Of these fifty (50) remaining watersheds locations one hundred eighty-four (184) monitoring sites were analyzed. Only sixty-nine (69) of these monitoring sites were found to have enough data for analysis. Forty-eight (48) sites saw improvement in nutrient levels, where overall post-implementation exceedance probability for critical thresholds (defined as 1 mg/l for N and 0.1 mg/l for P) decreased. Twenty-one (21) sites did not see improvement, where post-implementation exceedance probabilities did not show any reduction; in some cases, it showed an increase. Even among the efficient sites, where improvement was found, significant variation was observed in changes in exceedance probability with time, with many sites not demonstrating an expected uniform decreasing trend. It was also found that 56 out of the 72 water bodies had some biological indicator present, these included dissolved oxygen concentrations, benthic macroinvertebrate populations, fish communities/aquatic life, bacteria, and index scores. However, data gaps were detrimental to conclusively assessing BMPs with biological indicators. It was determined that sparse biological indicators data were not indicative of BMP success. These observations highlight the importance of designing a monitoring strategy that can capture these unexpected trends and allow a better understanding of BMPs. Along with better monitoring strategies, consistent and frequent monitoring is needed. Therefore, the effectiveness of best management practices was inconclusive due to a lack of available data on many sites.
