Description
This thesis proposes the creation of a web service, Pulse, which will function as a content aggregator for the hardcore eSports fan. The hardcore eSports fan is characterized as an individual who (1) spends at least 10 hours a week consuming or engaging in eSports content, (2) follow multiple eSports personas (players or teams), and (3) have streamed or attended at least one eSports tournament. This segment of the eSports fanbase is targeted because it represents a very invested portion of the 380 million total eSports fans engaged with streaming and potentially attending live events and purchasing team merchandise (Newzoo 2018). The eSports industry itself is expected to reach almost a billion dollars in 2018, and Pulse will seek by capitalize on this record valuation by connecting fans to the highlights they love and performance metrics they wish to see for a given eSports Participant.
Pulse will stand out from its competitors by offering the hardcore eSports fan a digital space that provides them everything they care about eSports at a glance. From tracking Participant and franchise metrics to notifying them of an upcoming event, Pulse will sort through the eSports data stream and present its users with a customizable aggregation feed to sort through in a social media-type environment. Forum posts and comment sections on highlight videos will also be included to facilitate a social experience for the browsing user if he or she wishes to engage with the wider Pulse community. The web service will perform monetization by selling advertisement space to free users, or through monthly subscription fees to Premium users. The Premium users are offered additional features of the Pulse web service, such as additional Participant metrics, full video catalog of eSports highlights, and more focused search results.

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.

Characterization and Manipulation of Microbiomes From Arid Landfills for Improved Methane Production
Description
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.

Today, we are experiencing a world where Net Neutrality exists in most of the countries around the world except a handful. Who knows if this will be the case in 10 years? An economy shifting from net neutrality to non-net neutrality could have an effect of wiping out an entire industry of start-ups and innovation. The main stakeholders in this industry are the Internet Service Providers (ISPs), who provide services to access, use and participate in the Internet such as AT\&T, Verizon and T-Mobile. The other main stakeholders are the Content Providers (CPs), who provide information or content to the end users through websites such as Netflix, Google, Wikipedia, etc. Before diving into the effects it has on the economy, let's discuss a little about what net neutrality and non-net neutrality really means and their pricing strategies. Typically in an economy where net neutrality exists, the ISPs charge a fixed price to the CPs and the end-users. The ISPs tend to compete on price in order to attract the CPs to use their service for content due to tight competition among the ISPs to capture profits. Thus, these costs to the CPs would be minimal, encouraging individuals from all over the world to innovate and provide content to the end users. The price burden in this case would fall not on the CPs but on the end users. But, ISPs may not be able to over charge the end users either, as they would lose their demand due to competition from other ISPs. Therefore, in spite of being the bearers of heavy investment costs to improve network quality, the ISPs haven't been enjoying profits for a long time. Meanwhile, the CPs are gaining large profits with minimal investment costs thanks to their market power over the ISPs.

Introduction: The Eye to Eye mentorship program is a national program in which college or high school students with learning differences mentor middle school students with learning differences. There are 68 Eye to Eye programs around the country, but little research has been done on their effectiveness and how to improve it. We conducted and evaluated one program site at Arizona State University and implemented this mentorship program for the first time during 2019. We hypothesized the Eye to Eye mentorship program that paired college students who have learning differences with middle school students who have similar learning differences would improve the outcomes and socio-behavior skills of both mentors and mentees.
Methods: The Eye to Eye mentorship program assessed involved mentors and mentees who completed 12 in-person art sessions out of the normal 20 in-person sessions. The first main assessment was the BLD (Breger Learning Difference) Feedback Survey addressing one’s experience in the Eye to Eye program and which were completed at the end of the mentorship program and filled out by mentors, mentees, and mentees parents (one parent for each mentee). A total of 12 mentors, 6 mentees, and 6 mentee parents were included in the feedback survey final analysis. The second main assessments were the pre and post Behavior Assessment System for Child, Third Edition (BASC-3) provided to mentors, mentees, and mentees parents (one parent for each mentee). A total of 10 mentors, 5 mentees, and 5 mentee parents were included in pre and post BASC-3 final analysis. Fall 2019 (pre) and Spring 2020 (post) optional interviews involved 5 mentors and 3 mentees who showed interest and were comfortable participating with additional release forms.
Results: The program was generally positively rated in the feedback survey by mentors, mentees, and mentee parents. The highest responses for mentors, mentees, and mentee parents all incorporated average ratings of 4.0 or higher (out of 5.0) for perceived understanding of socio-emotional skills after Eye to Eye, experience in Eye to Eye, how having a mentor or mentee made them feel, and perceived change in self-awareness. All three groups reported fairly high ratings of improved self-awareness of 4.0/5.0 or above. No negative ratings were provided by any participants and the lowest response was no change. The BASC-3 evaluation found statistically significant improvement in mentors’ anxiety and atypicality and mentees’ sense of inadequacy.
Discussion: The Eye to Eye program was popular and well-rated despite only involving 12 in- person one-hour art sessions. The mentors, mentees, and mentee parents felt positive about the Eye to Eye program when answering the feedback survey. Some suggestions are made on how to improve this program to better enhance someone with learning differences future ability to succeed. Future research is needed to assess the true impact due to the COVID-19 epidemic and other limitations.

The number of seniors who use technology continues to grow every day. Since technology has rapidly evolved in recent years, seniors often lack the skills to comfortably use it. This fact was made especially clear when one of the group members heard the story of a neighbor helping seniors in the community learn to better operate and understand technology. That story prompted the creation of a business designed to assist seniors in using technology. In this paper we will discuss our business model for a start up company named SenTech (Senior Tech Solutions) that was created by three college students. SenTech will provide various services to assist seniors with their technological needs within the scope of Apple products. We will discuss the problem, barriers, competitive advantages, marketing strategy, solution, financials, and future of SenTech.
The challenges our team faced were mainly due to COVID-19 and the social distancing guidelines provided by the CDC. Because of this, we were not able to conduct as many interviews as we planned. We also hoped to prepare a training course for seniors, but our plans were disrupted, so we shifted to a more research-based study.

In arid environments such as Arizona, agricultural producers are burdened by constraints placed on them by inhospitable weather and limited access to water and fertile soil when attempting to grow produce. Farms in the arid Southwest often have to build greenhouses to overcome such constraints; however, such greenhouses may be relatively space, water, and pesticide intensive and often have demanding maintenance needs and overhead costs. In addition, many current agricultural practices exhaust land resources disparagingly, leading to irreversible environmental degradation. In an effort to improve agricultural production for those limited by weather and resource constraints while simultaneously increasing sustainability in land, resource and pesticide use, we have created Valleyponics, a hydroponic growth services company centered around creating a minimal farming footprint. The company uses a consultative services approach, leveraging NASA Veggie Growth System Technology to provide solutions to large businesses by automating their agricultural production processes and minimizing resource use year-round. Valleyponics aims to cultivate consultative partnerships which will allow our clients, their communities, and the environment to flourish.
