Description
This thesis deals primarily with contemporary Brazilian civil-military relations. For most of the 20th century Brazil’s political system was stuck in a cycle of repeated military intervention. At present, Brazil operates as an electoral democracy and has kept the military out of politics since 1985. In order to understand the likelihood of another coup d’état, this thesis considers threats to the military’s corporate interests and deflations of the government’s political legitimacy within Brazil. Given the lack of significant threats to the military’s self-interest and the absence of serious legitimacy deflations, the Brazilian government appears unlikely to have a coup d’état in the near future. It is, however, important to remember that the 2014 World Cup and 2016 Summer Olympics could challenge Brazil’s current political stability and alter the likelihood of military intervention.

Description
This focuses on recent changes in Arizona eminent domain law regarding the question of whether a use be "truly public." In light of the landmark decision in Bailey v City of Mesa--often lauded as a great victory for proponents of private property rights-- a few sources will be reviewed to provide an indication of the extent redevelopment in Arizona has been affected by the decision. While the result in Bailey, precluding the City from taking the subject property may have been the correct outcome, the test to which the case now subjects any similar case involving redevelopment has made it unnecessarily difficult for political subdivisions of the state to carry out legislated redevelopment goals. The Bailey case only served to convolute the question of "public use" in the context of economic development, rather than create a workable body of law. In addition to providing a historical context and analyzing the effect of new interpretations on redevelopment generally, this paper will critique the Bailey decision in order to resolve the conflict that the decision created: that of the redevelopment goals of the state and municipalities and the authorized use of condemnation to achieve these goals with the judiciary's decision to greatly restrict the use of condemnation for the achievement of redevelopment goals. Arguably this conflict arose from a failure to fully understand the complexities of the use of the power of eminent domain for redevelopment purposes. Unaware of the need to use eminent domain in order to speed along and make possible economic redevelopment, overzealous proponents of property rights have reduced the issue to a narrow view of the state vs. the individual. Hopefully this paper can offer a more moderate and unbiased view of the use of eminent domain in light of the charge of the state and municipalities to facilitate economic growth.

Description
This thesis determines how first ladies portray their role through their speeches and whether this role meets partisan voters' expectations. Research includes an examination of first ladies' biographical information, content analysis of various speeches, and analysis of public polls to determine Republicans' and Democrats' role expectations and the role that first ladies portray. Analysis shows that first ladies meet some of their partisan voters' expectations and that party identification greatly influences the role they enact.

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
Former NFL player Colin Kaepernick began protesting during the national anthem in 2016. This research addresses the impacts that Kaepernick and his protests had on himself, the NFL, and the issues he was protesting. The research finds that Kaepernick was blackballed out of the NFL and that hundreds of other NFL players joined him in protest, which caused the league to ban the action before eventually becoming more political as a league. Additionally, the protests brought greater awareness to the issues and prompted some to become more politically active. In addition to providing a new framework for researching examples of politics in sports, this project concludes that athlete-activists can sacrifice themselves to provide more freedom for future athletes to be activists.

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
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
In today’s society we see an increasing amount of food being wasted because of impractical aesthetic production standards and idealistic consumer standards. Unrealistic ideals regarding outward produce appearance drive these standards. As imperfect, ugly produce waste is on the rise, further research on what drives consumer preferences is necessary to combat this growing issue. Variations in outside appearance deem produce imperfect despite its perfectly normal interior quality. In this research, I will explore whether a market segmentation variable such as political ideology drives purchase for imperfect, inferior produce. I will also explore whether a balance salient condition, indicated through balance-oriented slogans, drives purchase for imperfect, inferior produce. I will study the differences between vertical differentiation and horizontal differentiation as they relate to consumer identity. I will also study how all consumers, in particular conservatives, utilize balance motive and compensatory reasoning to justify their purchasing decisions. In a polarized society with dominant political identities, marketers can more easily target consumers through their political opinions. By understanding consumers’ ideology, marketers can improve marketing efforts that will ultimately better appeal to their rationale. Through a pretest measuring how many oranges were taken in balance-oriented conditions and a main field study, I investigate how political ideology plays a role in influencing the number of imperfect, inferior oranges taken. I also investigate how balance salient conditions play a role in influencing how many imperfect, inferior oranges consumers will take. This study opens doors for future research to further investigate how political ideology and balance salient conditions may impact consumer preference for imperfect, unattractive produce items.
