Description
The El Niño Southern Oscillation (ENSO) consists of a linkage between changes in sea-surface temperatures and atmospheric pressure across the Tropical Pacific. ENSO encompasses three phases: neutral events, warm/El Niño events in which sea-surface temperatures are warmer-than-normal and the pressure gradient decreases across the Equatorial Pacific, and cold/La Niña events

The El Niño Southern Oscillation (ENSO) consists of a linkage between changes in sea-surface temperatures and atmospheric pressure across the Tropical Pacific. ENSO encompasses three phases: neutral events, warm/El Niño events in which sea-surface temperatures are warmer-than-normal and the pressure gradient decreases across the Equatorial Pacific, and cold/La Niña events in which Tropical Pacific sea-surface temperatures are cooler-than-normal and the pressure gradient increases. Previous studies have determined a connection between variations in ENSO phase and weather patterns across the globe, focusing particularly on surface temperature and precipitation patterns in the United States. However, little research exists that attempts to link changes in ENSO phase with severe weather in Arizona. Therefore, in this study, I analyzed how variations in ENSO phase affect the frequency, intensity, and spatial distribution of four types of severe weather from 1959 to 2016 in Arizona, including a) tornado events, b) severe thunderstorm wind events, c) hail events, and d) heavy rain and flash flood events. I collected data on the Oceanic Niño Index (ONI), a measure of ENSO, as well as storm reports for each severe weather phenomenon dating back to 1959. Then, I analyzed the frequency of each Arizona severe weather event type within each of the twelve annual months and over the entire study period. I also analyzed mean intensity values (Fujita/Enhanced Fujita Scale rating, path width, and path length for tornadoes; hail diameter in millimeters for hail; and wind gust speed for severe thunderstorm wind events) for each severe weather phenomenon, excluding the heavy rain and flash flood events. Finally, I used the Mean Center and Directional Distribution tools in ArcGIS to determine variations in the spatial distribution and mean centers between each ENSO phase for each severe weather event type. I found that ENSO phase, particularly La Niña, does impact the frequency and intensity of tornadoes, hail, thunderstorm wind, and heavy rain/flash flood events in Arizona. However, it appears that ENSO does not affect the spatial distribution of these Arizona severe weather phenomena. These findings attempt to fill in the gap in the literature and could help meteorologists better forecast changes in Arizona severe weather, in turn allowing Arizonans to better prepare for and mitigate the effects of severe weather across the state.

Protest has been both a practice of citizenship rights as well as a means of social pressure for change in the context of Mexico City's water system. This paper explores the role that citizen protest plays in the city's response to its water challenges. We use media reports of water protests to examine where protests happen and the causes associated with them. We analyze this information to illuminate socio-political issues associated with the city's water problems, such as political corruption, gentrification, as well as general power dynamics and lack of transparency between citizens, governments, and the private businesses which interact with them. We use text analysis of newspaper reports to analyze protest events in terms of the primary stimuli of water conflict, the areas within the city more prone to conflict, and the ways in which conflict and protest are used to initiate improved water management and to influence decision making to address water inequities. We found that water scarcity is the primary source of conflict, and that water scarcity is tied to new housing and commercial construction. These new constructions often disrupt water supplies and displace of minority or marginalized groups, which we denote as gentrification. The project demonstrates the intimate ties between inequities in housing and water in urban development. Key words: Conflict, protest, Mexico City, scarcity, new construction

Abstract Older adults and people with disabilities are two unique populations, though they intersect in their need for mobility options that are often not met by traditional transportation services. There is consensus that the government should provide assistance for older adults and people with disabilities to achieve and maintain independence.

Abstract Older adults and people with disabilities are two unique populations, though they intersect in their need for mobility options that are often not met by traditional transportation services. There is consensus that the government should provide assistance for older adults and people with disabilities to achieve and maintain independence. However, the challenge lies in addressing the many forms of mobility inequity. Population projections for the twenty-first century have sparked interest in the rights of these two populations. As the population of the United States of America ages, supporting the mobility of seniors and individuals with disabilities will become imperative to maintaining their quality of life. One existing federal grant, Section 5310: Enhanced Mobility for Seniors and Individuals with Disabilities (49 U.S.C. 5310) provides formula funding for services that provide transportation options to older adults and people with disabilities. While the 5310 program provides crucial funding to non-profits and government agencies to support mobility options for older adults and people with disabilities, it does not address the full scope of mobility issues faced by these two communities. This thesis project provides a thorough analysis of this grant from the federal legislation it is founded on, to the local administration of this grant as applied by the Maricopa Association of Governments (MAG). Finally, this thesis looks at emerging technology with the potential to revolutionize mobility, along with sobering historical context of the barriers faced older adults and people with disabilities.

Libraries have historical and contemporary importance as public spaces that serve a purpose beyond storing books. In our thesis project, we wanted to ensure that the ASU Library was fulfilling this role for our student community. Based on a survey of 136 members of the Arizona State University community regarding accessibility of the Libraries, the results found that the ASU Library system could benefit from more accessible and digital content and programming. In response to our findings, we created a digital book display which highlighted resources about critical disability studies, the importance of community spaces and libraries in particular, as well as information about universal design. This book display serves as an example of what the future of book displays could be and how to create inclusive spaces in the university Library system.
