Description
Many developing countries do not have health care systems that can afford technological biomedical devices or supplies to make such devices operational. To fill this void, nonprofit organizations, like Project C.U.R.E., recondition retired biomedical instrumentation so they can send medical supplies to help these developing countries. One of the issues with this is that sometimes the devices are unusable because components or expendable supplies are not available (Bhadelia). This issue has also been shown in the Impact Evaluations that Project C.U.R.E. receives from the clinics that explain the reasons why certain devices are no longer in use. That need underlies the idea on which this honors thesis has come into being. The purpose of this honors project was to create packing lists for biomedical instruments that Project C.U.R.E. recycles. This packing list would decrease the likelihood of important items being forgotten when sending devices. If an extra fuse, battery, light bulb, cuff or transducer is the difference between a functional or a nonfunctional medical device, such a list would be of benefit to Project C.U.R.E and these developing countries. In order to make this packing list, manuals for each device were used to determine what supplies were required, what was necessary for cleaning, and what supplies were desirable but functionally optional. This list was then added into a database that could be easily navigated and could help when packing up boxes for a shipment. The database also makes adding and editing the packing list simple and easy so that as Project C.U.R.E. gets more donated devices the packing list can grow.

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
Research has examined the many motivations of international volunteers (voluntourists), but there is limited research about how volunteers are reached, as well as differing perceptions between travelers who have and have not traveled before. This study examines the preferences and perspectives of college-age, western backpackers. The general terms "backpacker" and "traveler" are used throughout the paper for simplicity, but it is important to note that these backpackers are specifically from the college-age, western demographic. First, the study addresses which recruitment avenues are the most successful, as well as which avenues could be utilized to increase the number of foreign, short-term volunteers. In addition, this study examines the differences between backpacker perceptions - specifically the differences in potential volunteering motivations and concerns. Data was collected through an anonymous online survey distributed to self-identified travelers between the ages of 18 and 25 in the United States and travel destinations in Vietnam and India. According to traveler responses, personal recommendations and hotels/hostels are important resources when making travel plans. Despite the importance of both resources, personal recommendations drew more travelers to volunteer than hostels/hotels (none of the travelers surveyed learned about their last volunteer opportunity through a hostel), revealing a potential avenue of recruitment. A small number of organizations have reported successfully utilizing the hostel-partnership model, which implies that successful partnerships are possible. Further, potential motivations to volunteer were similar between those who have and those who have not volunteered, however, potential concerns between the two groups differed. Those who had volunteered before reported to be considerably more concerned about adherence to cultural norms, as well as communication barriers, while those who had not volunteered were much more concerned about safety. These findings lead to several theoretical implications for nonprofits with respect to utilizing hostels for volunteer recruitment, as well as addressing concerns of those who have volunteered before differently from those who have not.

Description
This paper explores the history of sovereign debt default in developing economies and attempts to highlight the mistakes and accomplishments toward achieving debt sustainability. In the past century, developing economies have received considerable investment due to higher returns and a degree of disregard for the risks accompanying these investments. As the former Citibank chairman, Walter Wriston articulated, "Countries don't go bust" (This Time is Different, 51). Still, unexpected negative externalities have shattered this idea as the majority of developing economies follow a cyclical pattern of default. As coined by Reinhart and Rogoff, sovereign governments that fall into this continuous cycle have become known as serial defaulters. Most developed markets have not defaulted since World War II, thus escaping this persistent trap. Still, there have been developing economies that have been able to transition out of serial defaulting. These economies are able to leverage debt to compound growth without incurring the protracted consequences of a default. Although the cases are few, we argue that developing markets such as Chile, Mexico, Russia, and Uruguay have been able to escape this vicious cycle. Thus, our research indicates that collaborative debt restructurings coupled with long term economic policies are imperative to transitioning out of debt intolerance and into a sustainable debt position. Successful economies are able to leverage debt to create strong foundational growth rather than gambling with debt in the hopes of achieving rapid catch- up growth.

Description
Waste pickers are the victims of harsh economic and social factors that have hurt many developing countries and billions of people around the world. Due to the rise of industrialization since the 19th century, waste and disposable resources have been discarded around the world to provide more resources, products, and services to wealthy countries. This has put developing countries in a precarious position where people have had very few economic opportunities besides taking on the role of waste pickers, who not only face physical health consequences due to the work they do but also face exclusion from society due to the negative views of waste pickers. Many people view waste pickers as scavengers and people who survive off of doing dirty work, which creates tensions between waste pickers and others in society. This even leads to many countries outlawing waste picking and has led to the brutal treatment of waste pickers throughout the world and has even led to thousands of waste pickers being killed by anti-waste picker groups and law enforcement organizations in many countries. <br/> Waste pickers are often at the bottom of supply-chains as they take resources that have been used and discarded, and provide them to recyclers, waste management organizations, and others who are able to turn these resources into usable materials again. Waste pickers do not have many opportunities to rise above the situation they are in as waste picking has become the only option for many people who need to provide for themselves and their families. They are not compensated very well for the work they do, which also contributes to the situation where waste pickers are forced into a position of severe health risks, backlash from society and governments, not being able to seek better opportunities due to a lack of earning potential, and not being connected with end-users. Now is the time to create new business models that solve these large problems in our global society and create a sustainable way to ensure that waste pickers are treated properly around the world.

An Examination of the Partnerships Between Western Nonprofits and Nonprofits in Developing Countries
Description
This project outlines an examination of partnerships between Western-based nonprofit organizations and local nonprofits in developing nations. While these partnerships have the potential to address issues of cultural sensitivity and community empowerment, little is known about their best practices and potential pitfalls. This project aims to address this gap by using a case study approach and qualitative methods to examine partnerships between a Western-based nonprofit organization and local nonprofits in Southeast Asia. The project involved semi-structured interviews with staff and board members of all organizations and a review of organizational documents such as annual reports and communication efforts.

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 paper looks at factors that drive economic growth and show the correlation between economic growth and economic development and how important economic growth is for a developing country because when there is economic growth then the country has potential to develop. This paper continues to explain why there is economic growth in some countries and not in others with specifically focusing on the effects of having a blessed resource endowment. Having an abundance of resources should be a comparative advantage, however as seen in Latin America, South East Asia, and sub-Saharan Africa that this surprisingly does not lead to high levels of economic growth. This phenomenon is referred to as the Resource Curse and can be fully explained through assumptions derived from the macroeconomic Heckscher-Ohlin model as well as recent trends in emerging economies. Leading to the conclusion that developing countries abundant in resources are very susceptible to the Resource Curse through the increase inequality that ultimately stunts development. Literature suggests that one of the only solutions to overcoming the Resource Curse is the strengthening the effectiveness of the policies in place, which is a subsequent effect of having quality institutions.
Focusing on how to improve institutions there needs to be consideration of the fact that institutions have rent seeking behaviors because both local governments and foreign investors want to acquire a greater share of the production and the benefits. In attempt to find some solution of how countries can overcome the Resource Curse without having to totally reconstruct the political system the goal should be to be to focus on actions from the private sector. The private sector tends to magnify rent seeking behavior and to solidify any solution I performed interviews from industry leaders who have been working in economic development for the past decades. The purpose was to understand what companies are doing now to ensure sustainable development and how that has changed over the past decades.
In the end, the private industry is focusing on regulations that standardize polices for companies pursuing foreign direct investment requiring them to also focus on local economic growth and development. This requires foreign investors to understand the local culture, environment, and institutions leading to overall better choices for long term profitably, thus fulfilling their rent seeking tendencies. One of the biggest proven solutions is the Social License to Operate which is essentially an agreement created by the private investor that requires the local community to be informed and holds the investor accountable. In the end, if the private sector can positively impact a community whilst maintaining their own agenda then a country can overcome the Resource Curse.
