Description
Traditional crop production faces a significant challenge due to overapplication, mining, and decreased supply of mineral nutrients. In addition to this, the urgent need to address global food waste has become increasingly apparent, as discarded food scraps in landfills contribute to harmful greenhouse gas emissions. A promising solution that addresses both of these critical challenges includes the innovative utilization of food waste anaerobic digestate as a fertilizer for crop production. This study investigated whether using anaerobically digested food waste as fertilizer can fully replace or reduce the use of chemical fertilizer in vegetable and ornamental crop production. The seeds of lettuce (Lactuca sativa) ‘Nancy’ and petunia (Petunia × hybrida) ‘Easy Wave Velour Berry’ were sown into a soilless medium and grown in the indoor vertical farm at 22℃ under sole-source lighting at a photosynthetic photon flux density of 180 µmol∙m–2∙s–1 with a 20-h photoperiod. Four weeks after sowing, seedlings were transplanted and grown for three weeks in a greenhouse with an average daily temperature of 20 °C under ambient sunlight with an average daily light integral of 22 mol∙m–2∙d–1. The plants were fertilized using tap water mixed with different fertilizers, including a chemical fertilizer (15N-2.2P-16.6K), an organic fertilizer derived from anaerobically digested food waste (0.06N-0.026P-0.1191K), or a blend containing 50% chemical fertilizer and 50% food waste-based fertilizer, at the electrical conductivity of 0.7 mS·cm-1 during the young plant stage and 2.1 mS·cm-1 after transplant. At the young plant stage, lettuce and petunia have similar growth characteristics, including leaf number, SPAD index, and shoot and root fresh mass, when treated with either chemical or chemical + food waste fertilizer. In contrast, in both species, leaf area was 93-152% larger and fresh mass was 82-141% greater in plants treated with chemical or chemical + food waste fertilizer compared to food waste fertilizer. At the finishing stage, lettuce and petunia also showed similar growth and flowering characteristics under chemical or chemical + food waste fertilizer. However, in the lettuce finishing plants, fresh mass was 127-199% larger when supplied with chemical or chemical + food waste fertilizer compared to food waste fertilizer. In petunia, the number of flowers was 123-190% greater in chemical and chemical + food waste fertilizer compared to food waste fertilizer. In both lettuce and petunia at the finishing stage, the SPAD index, leaf number, root fresh mass, and root dry mass were similar among all treatments. These results suggest that food waste fertilizer applied as the sole source of plant nutrition is insufficient in comparison to chemical fertilizer at the same electrical conductivity. However, partially substituting some food waste fertilizer for chemical fertilizer reaps similar plant yield to chemical fertilizer on its own.

Description
This thesis considers various studies related to how COVID-19 has affected college students worldwide. This project provides an early examination of the literature in an effort to identify emerging themes, common global experiences, and areas still to be studied. First this project looks at how COVID-19 has exacerbated technological inequities, including the impacts of the digital divide on college students’ educations. This project shows how the lack of access to technology and the digital divide has deprived students of educational opportunities and has impacted their overall quality of education. Second, this project looks at the mental health impacts of the pandemic on college students. College students are already a very vulnerable population to begin with, and COVID-19 further exacerbated mental health issues among these students. Third, this project looks at findings about gender differences and the impacts of COVID-19 based on gender. This project also explores the positive impacts of the pandemic, and finally concludes with ideas for future research going forward, as well as solutions to the problems addressed in the project. This project reviews literature from a global perspective. Many of the studies in this project are taken from international university student populations, as it is important to compare how university students worldwide reacted to and were impacted by the pandemic. Taking this global view into perspective is necessary to formulate methods of action in the possible occurrence of a future health crisis of this scale.

Description
The policy design process in the United States has been guiding policymakers for decades. In order to keep up with the developing sustainability challenges that the US is facing, a new method of policy design needs to be determined for long-lasting, sustainable change. Human-centered design principles provide a new, unique perspective for analyzing sustainability challenges. Through the integration of human-centered design principles into policy systems, a new framework for policy design can be created. Through this project, a new framework that allows for the adaptation to new technologies, scientific information, and developments in the sustainability crisis to be accounted for and adequately addressed in future policies has been created.

In urban planning and design, creating emotional bonds, known as place identity, between people and their surroundings is paramount to improving the well-being of those who reside there. However, determining how to alter the built environment in order to increase place identity is a difficult task to achieve. Walkability is a good mechanistic link between the built environment and place identity. Walkability is comprised of a suite of factors that take into consideration both the natural and built environment. This thesis aims to determine if walkability is positively correlated with place identity in an extreme climate such as Phoenix. To test this, ecosystem services and disservices are used as factors to measure overall walkability. We found that access to recreational opportunities, aesthetic features of the pathway, and safety were all significant predictors of place identity. This has positive implications for walkable infrastructure to be strengthened in desert cities.

Description
This thesis is broken into two parts: the research and the toolkit. The research portion examines the benefits posed by the Barrett Student Engagement team to the Barrett Polytechnic community. Literature on student retention and attrition, inside and outside of an honors curriculum, was reviewed to better understand likely factors contributing to an increase of attrition rates. The primary question in focus is: “What are the benefits student engagement poses for Barrett Poly students?” followed by the secondary question of: “How can the student engagement team best support Barrett Poly students?” Data from the past five semesters has been collected and analyzed to determine the general trends and the strengths and weaknesses within each of the six engagement pillars. As the position of Student Engagement Assistant requires a fair amount of training for short-term employment (can be held until graduation from ASU), it is beneficial to have a training manual in place for workers to reference. The project has been made available in a hybrid format to best accommodate future changes in procedures and resources. A summary of the additional materials has been included at the end of this report.

The Human Chain: Exploring Poetry and Public Service is an anthology of collected poems that present the relationship between poetry and the concept of public service. Through academic and literary exploration, the main ties between the two concepts were identified as (1) loss, (2) community, (3) advocacy, (4) appreciation and (5) inspiration. The collection uses poetry to exemplify these thematic ties. The results of this project could be used to strengthen the relationship between the written word and organized volunteerism. There are many real-world applications of this literary exploration and is a vitally important relationship to delve into.

This thesis/creative project involved writing a collection of creative nonfiction essays and building a website to reflect on my experiences traveling through Spain in the summer of 2023, for both a study abroad program and on my own. There are a total of nine essays in this current collection, along with a tenth introductory essay. They reflect the chronological order of my travels to Madrid, Sevilla, Granada, Valencia, Barcelona, and Lisbon, concluding with an essay written about my return to Phoenix, Arizona. The goal of this project was to not only personally reflect on what I learned while in these various places, but also to share these experiences with a wider audience in the digital world. I plan to continue adding essays to this website, using it as a "living document" for my future travels, and as a place for further reflection.

After traveling to Spain to study abroad, I noticed a large amount of shops selling goods related to Japanese anime, which helped inspire the topic of my honors thesis. In this paper, the cultural impact of Japanese animation and comics on Spain is explored. The history/origin of anime in Spain, the early reception of these works in Spain, the importance of the anime fandom, the intersection between Spanish and Japanese culture in anime and anime-inspired films, and the positive representation of Spain in these works are all relevant topics that constitute the argument of this document. Sources in both English and Spanish are utilized.This paper explores the surprising connections between the two countries. The way in which their cultures interact through the consumption of this form of media was quite fascinating to look into.

Description
The ecological niche of a species can shift due to changing environmental conditions and lead to the species to undergo selective pressures to adapt to them. Ecological niche models are used to predict a species’ distribution based on its ecological niche. Ecological niche models can be integrated with a geographic information system to predict a species’ geographic distribution based on environmental variables. In this project, two reptile species that inhabit wide and variable geographic ranges, Uta stansburiana and Gopherus berlandieri, had their ecological niches predicted and mapped based off population data and climactic data. These ecological niche maps were then compared to sample populations of each species to infer and predict whether certain populations of each species were possibly under increased selective pressures. Based off these maps and comparisons, this study infers that the two species differ in which environmental variables are the most relevant to their suitability. This study also predicts that populations of U. stansburiana experiencing extremes in their most relevant values for temperature and precipitation could be under greater selective pressures, while populations of G. berlandieri experiencing lower values for their relevant temperature and precipitation variables could be under greater selective pressures. Furthermore, it can be inferred from this study that differences in these variables across each species’ range could be influencing genetic variation among their populations, in line with previous studies. Further genomic study of each species can be used to test these inferences.

Since urban sustainable development involves dynamic and complex systems, tools, and models to aid urban sustainable development must also reflect dynamism and complexity to foster resilience. System dynamics allows for an iterative and robust approach when studying complex problems. This approach applies both quantitative and qualitative data to help unveil the interconnected components and dependencies within a specific city or community. This study approaches urban sustainable development in terms of its environmental, social, and economic dimensions to holistically look at the different components of the system at various levels. Using Tempe, Arizona as a case study, this research and tool provides a conceptual framework in making strides towards dynamic and interconnected thinking that can be taken further to extend into different communities and levels.
