Description
The international disaster-relief organization Doctors without Borders (MSF) is a dynamic geopolitical actor. Using a systematic literature review of academic journal articles and first person accounts by doctors from the field, the geopolitical role of MSF was analyzed. This search returned a wide range of articles many of which referenced the term “humanitarian space”. MSF utilizes humanitarian space to accomplish their medical work and witnessing actions in disaster areas. MSF’s geopolitical role stems from many of the central characteristics of the organization, but the process of creating humanitarian space engages them differently at both a global and a local level. Case studies of MSF’s work in Haiti and Rwanda reveal the interplay between global and local levels. Humanitarian space at the global level is a more imagined space. At this level, MSF relies on their practice of “témoignage” or testifying as their primary method for creating this space. At the local level, MSF focuses on their humanitarian patient-care to earn themselves space uninhibited by other power-wielding groups. These two levels work as a see-saw so that when the humanitarian space occupied by MSF is threatened at one level they can lean on their space at other in order to continue providing the best services possible. During the Rwandan genocide, MSF’s on the ground was work was limited to a single hospital in a single city and to compensate, they worked hard at the global level to bring attention to the violent situation in the country. This balance switched in the aftermath of the Haiti earthquake of 2010 during which massive space for humanitarian action on the ground, made advocating at a local level unnecessary. Analysis of MSF from a political geography perspective opens up new avenues of examining the many interdisciplinary characteristics of an organization as wide-reaching as Doctors without Borders.

Description
The disputes in the South China Sea involve overlapping territorial claims from multiple nations and have grown increasingly contentious over the past decade. The area is rich in natural resources and is strategically significant regarding international trade and military capabilities. Due to the significance of the area, the competing claims have global ramifications and the conflict involves actors beyond the region. This paper examines the geopolitical factors involved in the disputes and how they shape states' actions in relation to the South China Sea. Specifically, this paper will show how China's actions in the South China Sea reflect both the geography of the region, and also its political ambitions in the region and international community. The states' claims contend the territory, territoriality, and sovereignty of islands in the South China Sea, and are based on both international law and historical evidence illustrated in the case between the Philippines and China in the Scarborough Shoal. It demonstrates China's tactics for managing competing claims, its increasing military capabilities, and the uncertainty of resolutions to the conflict. The mechanisms for the resolution of the territorial disputes in the South China Sea are shown to be largely ineffective given the differing basis of claims over the South China Sea states have. International institutions, such as United Nations tribunals, and other nations without direct claims in the South China Sea, such as the United States, have interests in the conflict related to the peaceful resolution of disputes between nations, while also influencing states' actions. This paper reviews the concepts of geopolitics and how China's strategy in the South China Sea reflects both critical and classical geopolitics and its objective of regional hegemony.

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
In this thesis I use reliable economic data and political reasoning to unravel the motive behind the collapse in oil and natural gas prices, which began in the summer of 2014. In the first two sections of this paper, I use economic data to disclose that the success and failure of the Russian economy has invariably depended on oil and natural gas prices. With this fact in mind, I go on to elucidate that high oil and gas prices from 1998-2008 attributed to Russia's robust economic growth during this period. I then assert that Russia's strong economy enabled Moscow to politically and/or military intervene in countries such as Georgia, Syria and Ukraine. With rising Russian aggression threatening the world and America's interests, I then claim that the significant increase in the production of U.S. oil and natural gas is probably prompted by the U.S. government, which is looking to debilitate the Russian economy by suppressing prices, and U.S. firms that want to maximize profits. Finally in section six, I assert that Russia's economy will eventually collapse as long as oil and gas prices remain below Russia's breakeven price. With Russia's economy in shambles, I then deduce that Moscow's power and global influence will also subside.

Description
The United States and China have entered a geopolitical competition for power and influence unseen since the Cold War. By examining the nature of this contest through the lens of Thucydides' History of the Peloponnesian War and Graham Allison's Thucydides' Trap theory, it is possible to analyze the nature of this relationship, and make predictions as to where it may lead.

As China is using its Belt and Road Initiative to solidify strategic partnerships, which China is consciously forming with the intention of engineering shifts in the regional balance of power, it strengthens its hegemony and therefore raises the significance of the BRI and CPEC as an instrument to position itself as an emerging global power. I will explore this thesis statement by using the China-Pakistan Economic Corridor as a case study.

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
This thesis approaches the concept of nationalism within the context of post-Soviet Estonian and Georgian state-building from a sociological perspective, building upon the work of Émile Durkheim, Bernard Yack, Anthony Smith, and Rogers Brubaker. Taking such a stance identifies nationalism as a social concept whose relationship with geopolitics and political integration comments on the merits of post-Soviet Estonian and Georgian geopolitical conditions and their respective state-building processes, specifically regarding ethnic minority and international integration. I argue that the cases of Estonia and Georgia demonstrate that social solidarity institutionalized in states and expressed through nationalism has significant effects on geopolitics and the integration of ethnic minorities into a broader multi-ethnic state as well as on the integration of a broader multi-ethnic state into the international community. This thesis demonstrates that the different paths that Estonia and Georgia took towards this integration indicate the significance not only of domestic nationalistic circumstances, but also of the larger geopolitical realities and underlying historic foundations in which and from which state-building must occur.
