Description
The predictors of school engagement in early childhood were examined, and mechanisms to improve classroom engagement levels were proposed for interventionists to consider. Literature was reviewed on the relations of child characteristics (i.e. effortful control, negative emotionality) and environmental characteristics (i.e. teacher-child relationship quality, classroom environment) to children's school engagement. Finally, a logic model was developed to guide future intervention work.

Description
Literature in public administration emphasizes a growing dissatisfaction with government on the part of residents. Where there tends to be a lack in the literature is in terms of solutions to this problem. We would like to argue that the engagement process itself has the power to foster a profound attitudinal shift on the part of both residents and government. This paper explores the structural and cultural barriers to satisfactory public engagement both from literature and a combination of policy analysis, semi-structured interviews and participatory observation within the City of Tempe. We then provide recommendations to the City of Tempe on how to overcome these barriers and effect authentic public engagement practices. With these new suggested practices and mindsets, we provide a way that people can have the power to create their own community.

Description
Many student engagement studies take a holistic view of the student experience at a university setting, which includes factors both inside and outside of the classroom. However, most engagement improvements focus on activities outside of the classroom. Some research regarding improving teaching styles and activities shows an impact on engagement, but little research has investigated the impact of the built environment on student engagement. This paper explores the definition of student engagement, what environmental variables affect building occupant performance, and specifically addresses how environmental variables can impact student engagement. The authors provide a review of literature discussing these variables as well as propose a method for quantifying the impact of the built environment on students based on results of a preliminary study. Evidence of a relationship between human comfort and student engagement can provide an argument for how thoughtful building designs can improve student success and engineering education. It can further extend to industry settings where green building design can lower operating costs and improve worker satisfaction and productivity.

Description
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.

Description
This thesis will focus on increasing the engagement of members within the W.P. Carey Business Ambassadors. This was done by first analyzing the environments the organization exists in: Arizona State University and the W.P. Carey School of Business. Each of these organizations contextualize the Business Ambassadors, providing a structure for the organization to operate within. Next, the organization’s processes are analyzed. This provides a current status of the club to be used a foundation for systematic review. Through this review, it is revealed that members often do the bare minimum required for the organization. In fact, only a select few fully taking advantage of the events offered by the club. To fix this, the management techniques outlined in the thesis’ primary source, Reframing Organizations by Lee Bolman and Terrence Deal, are introduced as ways to assist managers in problem sectors or areas of opportunity. These areas of review are the Structural, Human Resources, Political, and Symbolic frameworks. Each frame is explored and described, eventually being contextualized with the Business Ambassadors organization. These frames then provide insights to ways the organization can invoke greater participation from its members. These solutions include investing in training and mentorship, fulfilling member needs, promoting leadership, and leveraging the symbolic strength of the organization. The paper concludes with next steps for the organization and ways the solutions can be put into action with respect to the club’s goals.

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.

Description
The objective of this study is to gain a better understanding of the factors influencing internship engagement and determine if there is a notable difference between first-generation students and their non-first-generation counterparts. To achieve this goal, I surveyed students currently engaged in an internship or those who have completed one within the past three years.
The findings indicate that there is no significant difference between the two groups in terms of overall internship engagement. However, first-generation students reported experiencing higher levels of work-role fit and psychological meaningfulness. It's worth noting that psychological meaningfulness influences internship engagement.

Description
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.

Description
This project examines and builds a digital strategy for a college student-run organization, The Mouseketeers @ ASU, at Arizona State University. The strategy aimed to improve the club’s audience and engagement online and ultimately in person. The Mouseketeers @ ASU assists students with finding careers and connections within the Walt Disney Company while also bringing together students with similar interests. By identifying key interests of the target audience and combining this with numerous preferred social media techniques, the club will gain sources and participation through a new audience. Key components of this thesis are the creation of a new website and the use of three social media platforms. Because the internet is always changing, the analytics are taken from each of these platforms to always improve the overall strategy in order to reach the goal.
