Description
Influenza has shown its potential to affect and even kill millions of people within an extremely short time frame, yet studies and surveys show that the general public is not well educated about the facts about influenza, including prevention and treatment. For this reason, public perception of influenza is extremely skewed, with people generally not taking the disease as seriously as they should given its severity. To investigate the inconsistencies between action and awareness of best available knowledge regarding influenza, this study conducted literature review and a survey of university students about their knowledge, perceptions, and action taken in relationship to influenza. Due to their dense living quarters, constant daily interactions, and mindset that they are "immune" to fairly common diseases like influenza, university students are a representative sample of urban populations. According to the World Health Organization (WHO), 54% of the world's population lived in cities as of 2014 (Urban population growth). Between 2015 and 2020, the global urban population is expected to grow 1.84% per year, 1.63% between 2020 and 2025, and 1.44% between 2025 and 2030 (Urban population growth). Similar projections estimate that by 2017, an overwhelming majority of the world's population, even in less developed countries, will be living in cities (Urban population growth). Results of this study suggest possible reasons for the large gap between best available knowledge and the perceptions and actions of individuals on the other hand. This may lead to better-oriented influenza education initiatives, more effective prevention and treatment plans, and generally raise excitement and awareness surrounding public health and scientific communication.

Description
The thesis examines the Indonesian claim of H5N1 viral sovereignty in 2006, and the mutant H5N1 papers controversy in 2011, to analyze the notion of science transcending national boundaries and novel conflicts with science operating on the international stage, specifically for H5N1 preparedness. This thesis argues how the symmetries between the Indonesian sovereignty case and the H5N1 papers controversy illustrate the locus of contention and uncertainty present in the international scientific space, specifically related to the ownership and governance of influenza pandemic preparedness materials and research. To achieve this, the thesis comparatively analyzes the two controversies to reveal the unsettledness in dimensions of both pandemic preparedness and international and transnational governance of science. This symmetrical analysis clarifies the unresolved issues of ownership, control, and accountability, which exist in the scientific international space. The deliberations of both case studies were framed so that the primary goal of the resolutions developed into maintaining scientific openness for public health benefit. With this method of deliberation taken, the significant and unique issues raised by these cases, in addition to the ownership questions that were allowing these controversies to gain prominence, were commonly left unaddressed. In doing so, the potential of the reemergence for similar controversies remains high.

Description
This thesis studies the 1998-2003 doubling of the National Institutes of Health budget to evaluate how assertions about the impact of research investments compare with actual health and research outcomes. Stakeholders in the doubling noted a variety of outcomes intended to result from the effort. Using public value mapping (Bozeman and Sarewitz, 2005), I have compared stakeholders' stated intentions of what the doubling ought to achieve with the health and research outcomes actually produced. In applying public value mapping, I first conducted interviews and reviewed press releases, Congressional record, news, and other data from the doubling period. Six public values were commonly represented in this data: (1) improving health outcomes (2) reducing the cost of healthcare (3) producing application-relevant knowledge (4) building biosecurity and biodefense capabilities (5) developing the research enterprise (6) economic growth I then inferred causal logic chains by which increasing funding could lead to achievement of the public values and identified four investment intermediaries through which funding would pass in advancing public values. Finally, using proxies, I evaluated if the public values had advanced in a way directly attributable to funding increases. This analysis identified (5) as achieved. (1), (3), (4), and (6) were indeterminate in one of the two components necessary for evaluating public value achievement: either no clear advancement or no direct link between outcomes and doubling investments. (2) was a failure due to the increase in healthcare costs throughout and following the doubling period. These results indicate that complex societal outcomes used to justify incremental research investments are challenging to causally attribute to those same investments, and thus uncertain premises on which to base policy.

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
Science fiction themed video games, specifically Role Playing Games (RPGs) like Deus Ex: Human Revolution (DX:HR), that focus on an emerging technology, contain features that help to better inform anticipatory governance. In a game like DX:HR, players vicariously experience human-enhancement technology and its societal effects through their in-game character. Acting as the character, the player explores the topic of human-enhancement technology in various ways, including dialogue with non-player characters (NPCs) and decisions that directly affect the game's world. Because Deus Ex: Human Revolution and games similar to it, allow players to explore and think about the technology itself, the stances on it, and its potential societal effects, they facilitate the anticipatory governance process. In this paper I postulate a theory of anticipatory gaming, which asserts that video games inform the anticipatory governance process for an emerging technology. To demonstrate this theory I examine the parts of the anticipatory governance process and demonstrate RPG's ability to inform it, through a case study of Deus Ex: Human Revolution.

Description
The thesis will explore sources of scientific funding, analyze the impacts of intellectual property, describe the reproducibility/replicability crisis, and explore various scientific policies. Additionally, this thesis will determine whether all scientific findings should be released for total transparency, if everything should be kept under lock and key to maximize profits and protect the intellectual property of the scientists, or if there should be some healthy medium between the two. For each option, the inherent positives and negatives will be discussed to show how scientific research can change to best fit the needs of everyone involved. Furthermore, this thesis will explore possible solutions to remedy the issues found and how such propositions can be reasonably applied. The research was conducted through a series of interviews with expert faculty members on the Arizona State University Campus. Ultimately, in order for improvements to be made, a number of changes need to happen at a foundational level through a series of new science policy and research practice implementations.

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.

Engineering – The Social Experiment: An Analysis of Engineering Curriculum and Industry Expectations
Description
The engineers of the future are currently in the process of earning their degrees and certifications from engineering programs guided by ABET accreditations. ABET, the Accreditation Board for Engineering and Technology, is the voice of reason for the development of engineering programs. Aspiring engineers desire institutions that follow ABET Standards to ensure that their education meets the expectations of industry partners and researchers. However, these standards have not been drastically altered in years to reflect the changing needs of industry. With the advancement of technology in the last two decades, old school engineering and its application is becoming less common.
Science policy and curriculum go hand in. The future engineers are taught hand calculations, lab testing for field work parallels, and methodologies based on the written policies set forth decades ago. Technology today is rapidly changing, and engineering education is struggling to make changes to keep up with these technology advancements. In today’s world, technology drives invention and innovation, whereas some argue it is thought and curiosity. Engineering programs are taking a toll regardless of the point of view. Education is not made to keep up with current societal needs.
This paper a provides an overview of the history of engineering, curriculum standards for engineering programs, an analysis of engineering programs at top universities and large universities alongside student experiences available to engineers. The ideas offered are no means the exact solution; rather policymakers and STEM education stakeholder may find the ideas shared helpful and use them as a catalyst for change.

Description
In this paper, I aim to assess the ethical and policy issues at the forefront of developmental biology, mainly, the 14-day guideline dictating human embryo research. Ever since the invention of in vitro fertilization in the 1970s, the research landscape of human embryo research has been well explored. Now, there are new embryonic technologies and human embryonic stem cell based models that many believe do not fit into current guidelines. This paper analyzes four of these new technologies-- stem cell derived gametes, embryoids, 3D printed embryos and synthetic embryos-- in order to explore the impetus for reopening the debate on the 14-day guideline. The paper then explores current research and research projects while comparing and contrasting science as well as the potential for moral status and how that impacts regulation. Current United States policies and regulations as well as current professional society guidelines are broken down to fully grasp the political landscape surrounding human embryo research. Notably, current policies include the complete lack of a federal definition of an embryo as well as the Dickey-Wicker Amendment which restrict funding for human embryo research. It is thus advised that these, along with the 14 day guideline, are updated in order to encapsulate the early human developmental research landscape and promote research. This paper ends with an in depth policy recommendation including (but not limited to) bill language, suggested definitions and potential strategies.
