Currently conventional Subtitle D landfills are the primary means of disposing of our waste in the United States. While this method of waste disposal aims at protecting the environment, it does so through the use of liners and caps that effectively freeze the breakdown of waste. Because this method can keep landfills active, and thus a potential groundwater threat for over a hundred years, I take an in depth look at the ability of bioreactor landfills to quickly stabilize waste. In the thesis I detail the current state of bioreactor landfill technologies, assessing the pros and cons of anaerobic and aerobic bioreactor technologies. Finally, with an industrial perspective, I conclude that moving on to bioreactor landfills as an alternative isn't as simple as it may first appear, and that it is a contextually specific solution that must be further refined before replacing current landfills.

University Devils is a Founders Lab Thesis group looking to find a way for post-secondary institutions to increase the number of and diversity of incoming applications through the utilization of gaming and gaming approaches in the recruitment process while staying low-cost. This propelling question guided the group through their work. The team’s work primarily focused on recruitment efforts at Arizona State University, but the concept can be modified and applied at other post-secondary institutions. The initial research showed that Arizona State University’s recruitment focused on visiting the high schools of prospective students and providing campus tours to interested students. A proposed alternative solution to aid in recruitment efforts through the utilization of gaming was to create an online multiplayer game that prospective students could play from their own homes. The basic premise of the game is that one player is selected to be “the Professor” while the other players are part of “the Students.” To complete the game, the Students must complete a set of tasks while the Professor applies various obstacles to prevent the Students from winning. When a Student completes their objectives, they win and the game ends. The game was created using Unity. The group has completed a proof-of-concept of the proposed game and worked to advertise and market the game to students via social media. The team’s efforts have gained traction, and the group continues to work to gain traction and bring the idea to more prospective students.

This thesis recalls a famous Greek comedy's critique of higher education and examines how it might apply to the modern university. In order to understand the application of such a critique, this thesis necessarily works to define the spirit of the university as it was formed in the cross-civilizational decedents of Plato's Academy. After the first universities, I examine the development of higher education in the United States. Ultimately I argue that the Aristophanic critique of Socrates and higher education is applicable in a very important way to the modern university. I offer two policy recommendations that might offer an important starting point for recalling the spirit of the university.

Environmentally harmful byproducts from solid waste’s decomposition, including methane (CH4) emissions, are managed through standardized landfill engineering and gas-capture mechanisms. Yet only a limited number of studies have analyzed the development and composition of Bacteria and Archaea involved in CH4 production from landfills. The objectives of this research were to compare microbiomes and bioactivity from CH4-producing communities in contrasting spatial areas of arid landfills and to tests a new technology to biostimulate CH4 production (methanogenesis) from solid waste under dynamic environmental conditions controlled in the laboratory. My hypothesis was that the diversity and abundance of methanogenic Archaea in municipal solid waste (MSW), or its leachate, play an important role on CH4 production partially attributed to the group’s wide hydrogen (H2) consumption capabilities. I tested this hypothesis by conducting complementary field observations and laboratory experiments. I describe niches of methanogenic Archaea in MSW leachate across defined areas within a single landfill, while demonstrating functional H2-dependent activity. To alleviate limited H2 bioavailability encountered in-situ, I present biostimulant feasibility and proof-of-concepts studies through the amendment of zero valent metals (ZVMs). My results demonstrate that older-aged MSW was minimally biostimulated for greater CH4 production relative to a control when exposed to iron (Fe0) or manganese (Mn0), due to highly discernable traits of soluble carbon, nitrogen, and unidentified fluorophores found in water extracts between young and old aged, starting MSW. Acetate and inhibitory H2 partial pressures accumulated in microcosms containing old-aged MSW. In a final experiment, repeated amendments of ZVMs to MSW in a 600 day mesocosm experiment mediated significantly higher CH4 concentrations and yields during the first of three ZVM injections. Fe0 and Mn0 experimental treatments at mesocosm-scale also highlighted accelerated development of seemingly important, but elusive Archaea including Methanobacteriaceae, a methane-producing family that is found in diverse environments. Also, prokaryotic classes including Candidatus Bathyarchaeota, an uncultured group commonly found in carbon-rich ecosystems, and Clostridia; All three taxa I identified as highly predictive in the time-dependent progression of MSW decomposition. Altogether, my experiments demonstrate the importance of H2 bioavailability on CH4 production and the consistent development of Methanobacteriaceae in productive MSW microbiomes.

Zero-Valent Metals (ZVM) are highly reactive materials and have been proved to be effective in contaminant reduction in soils and groundwater remediation. In fact, zero-Valent Iron (ZVI) has proven to be very effective in removing, particularly chlorinated organics, heavy metals, and odorous sulfides. Addition of ZVI has also been proved in enhancing the methane gas generation in anaerobic digestion of activated sludge. However, no studies have been conducted regarding the effect of ZVM stimulation to Municipal Solid Waste (MSW) degradation. Therefore, a collaborative study was developed to manipulate microbial activity in the landfill bioreactors to favor methane production by adding ZVMs. This study focuses on evaluating the effects of added ZVM on the leachate generated from replicated lab scale landfill bioreactors. The specific objective was to investigate the effects of ZVMs addition on the organic and inorganic pollutants in leachate. The hypothesis here evaluated was that adding ZVM including ZVI and Zero Valent Manganese (ZVMn) will enhance the removal rates of the organic pollutants present in the leachate, likely by a putative higher rate of microbial metabolism. Test with six (4.23 gallons) bioreactors assembled with MSW collected from the Salt River Landfill and Southwest Regional Landfill showed that under 5 grams /liter of ZVI and 0.625 grams/liter of ZVMn additions, no significant difference was observed in the pH and temperature data of the leachate generated from these reactors. The conductivity data suggested the steady rise across all reactors over the period of time. The removal efficiency of sCOD was highest (27.112 mg/lit/day) for the reactors added with ZVMn at the end of 150 days for bottom layer, however the removal rate was highest (16.955 mg/lit/day) for ZVI after the end of 150 days of the middle layer. Similar trends in the results was observed in TC analysis. HPLC study indicated the dominance of the concentration of heptanoate and isovalerate were leachate generated from the bottom layer across all reactors. Heptanoate continued to dominate in the ZVMn added leachate even after middle layer injection. IC analysis concluded the chloride was dominant in the leachate generated from all the reactors and there was a steady increase in the chloride content over the period of time. Along with chloride, fluoride, bromide, nitrate, nitrite, phosphate and sulfate were also detected in considerable concentrations. In the summary, the addition of the zero valent metals has proved to be efficient in removal of the organics present in the leachate.

Since the days of Plato’s Academy and Aristotle’s Lyceum, the intellectual community has been divided in two. This division has continued into the present day, most notably evidenced by the dichotomy between science and arts majors. There has been much debate over the last two centuries regarding how to bridge this divide, and whether or not doing so is necessary. Scholars like C. P. Snow have argued that interdisciplinary education is humanity’s only hope for confronting its current and future problems, while scholars like F.R. Leavis believe calls to restructure education are an oversimplification of a more complex problem. With its emphasis on global and local outreach, interdisciplinary education, and use-inspired research, the New American University model currently in use by Arizona State University is a literal attempt at bridging this divide. Schools like the College of Integrated Sciences and Arts have created an environment that encourages interdisciplinary collaboration. President Crow attributes this progress to what he calls “the design approach.” Unlike a rigid blueprint, the design approach instead looks at each problem in isolation, allowing for a unique solution to be tailor-made to fit each scenario. Despite the initial successes of the New American University model, however, it is still important to remain observant and critical of its practices into the future, as too much of an emphasis on interdisciplinarity could have the opposite of its intended effect, and potentially drive students who wish to specialize away from traditional universities altogether.

This paper argues that improved student disability services at universities can limit the amount of stress that burdens students with disabilities in order to, improve their mood and create greater possibilities for successful student outcomes. This study begins by reviewing the progress that has been made in the 20th and 21st centuries in terms of heightened awareness and legislation that benefit people with disabilities. In addition, it applauds the efforts made so far at the Arizona State University Polytechnic and Tempe campuses, but also seeks to highlight some concerns that might become a focus of future policymaking endeavors. The applause and concerns are based on the experience of the author with ASU’s Disability Resource Center (DRC), now rebranded as the Student Accessibility and Inclusive Learning Services (SAILS). The author’s lens of physical/mobility limitations yields insight into the accessibility of the unique programs
offered by ASU’s Study Abroad Office as well as the daily transportation efforts of the DRC/SAILS’s DART service. The particular experiences discussed include a Barrett Global Intensive Experience trip to Ireland, the use of the on-campus DART transportation service at Polytechnic and Tempe, handicap parking and elevator placement at Polytechnic, the intercampus shuttle, and the future of Zoom as a means of providing accessibility to students with disabilities. This paper will make recommendations to the appropriate parties for possible changes to policy and/or procedure and alterations to the current state of tangible obstacles.

This project analyzes aspects of ESports and gaming in relation to college/university students and college/university campuses. The specific focus of the project was establishing that there was an interest in additional Esports and gaming engagement on campus and then determining what manner of engagement was most desired by students. In order to discover the most popular form of Esports and gaming engagement for students, we held two events: a recreational ESports Competition and tutorials to teach students how to mod video games. After carrying out these events we established that an Esports Competition was a more popular form of engagement. However, we also established that both forms of engagement would be successful with proper marketing and execution.
