Description
This study examines the social construction of the border by researching how frequently select issues are written about by the media of both countries, and in what light two different groups of actors (Mexico and the US) are portrayed. The Dallas-based The Dallas Morning News, and the Monterrey-based, El Norte are the two newspapers chosen to perform the content analysis. Furthermore, this study seeks to examine differences in the way both newspapers portray the US-Mexico border in 1994, or the year NAFTA began, and 2012, the most recent year for which data is available. A major find of this study is the discovery of how even though the frequency that select issues are brought up in the border vary drastically by year and newspaper, portrayals of the actors around the border stay fairly consistent. More specifically, with the exception of NAFTA in 1994, border issues outside of crime, illegal immigration, drug violence, and the economy, are rarely mentioned by the two selected newspapers a significant amount of the time. Also, issues at the border such as crime, drug violence, and national security are often portrayed as the fault of Mexico and Mexican actors, while immigration issues at the border are often blamed exclusively on each newspaper's host countries.

This creative project was designed to highlight the good that can come from playing video games using From Software's "Dark Souls" as a case study.In this project, I analyse "Dark Souls" as an allegory for depression, examining how the story, game play and level design all create a mindset in the game's players similar to that of those experiencing depression. I then discuss how certain aspects of the game, including level design, the game mechanics used to handle in-game death, and the passive multiplayer systems, all combine in order to encourage the player to stay engaged with the game and believing in the possibility of success. Via these systems, I believe that in creating "Dark Souls" From Software made an experience in which those grappling with depression can practice the techniques most useful in combating depression in a safe environment. Finally, I discuss the ways that "Dark Souls" designers emotionally affect those playing their game using techniques that are unavailable to other media. I highlight these storytelling devices, and explain why they are either best utilized by or only viable in video games as an example of what unique abilities gaming has as a cultural storytelling medium. I also explore solutions for discussing video game mechanics and game play with a non-gaming audience, utilizing game play recordings to provide examples of the discussed game play mechanics. These techniques can be viewed in the attached video.

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.

I will argue that Fletcher as a queer female musician is less focused on physical beauty, but instead is more focused on inner beauty and the character of women instead. I will begin with defining beauty in its many forms and how this industry and market has grown in recent years through a review of the current literature in the applicable fields of study. The other side of this endeavor will be a review of selected song lyrics and an analysis of how they describe feminine beauty. This will demonstrate that queer women view and describe women differently- and in a more positive and humanizing manner.

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.
