    Accelerating Innovation: Assessing Nanotechnologies, Prototypes and Research Teams
    Shaler, Lisa Marie (Virginia Tech, 2019-04-29)
    The Army-sponsored Institute for Soldier Nanotechnologies (ISN) was an entrepreneurial research institute established at the Massachusetts Institute of Technology (MIT) in 2002. Using Science and Technology Studies (STS) concepts from Actor-Network Theory, I study the founding era of this twenty-first century laboratory-based community, from 2002-2007. Actor-Network concepts of enrollment and translation, described by Bruno Latour, and heterogeneous engineering, described by John Law, are used as I 'follow the actors' founding this emergent institution. The operationalization of translation is traced through four case studies, structured around Defense funding constructs and Science and Technology communities: 6.0 Founding the Institute; 6.1 Building Basic Research Networks; 6.2 Shaping Applied Research for Cancer Research and Science Education to include non-users; and 6.3 Student Prototyping Teams Accelerating ISN Research for Traumatic Brain Injuries (TBI). Scientists, engineers, and transitioners partnered in new ways to transition innovative technologies to improve human protection, with soldiers as the first of many users. Using public information, I used qualitative and quantitative methodologies to assess the actor networks and research portfolio changes. These historical case studies extend STS with operationalization of translation and a new dynamic of bi-directional actor enrollment, as research teams transitioned nanotechnologies and prototypes.

    Acquiring Expertise? Developing Expertise in the Defense Acquisition Workforce
    Mullis, William Sterling (Virginia Tech, 2015-03-30)
    The goal of this research project is to tell the story of acquisition expertise development within the DOD using the evolution of the Defense Acquisition University as its backdrop. It is a story about the persistent frame that claims expertise leads to acquisition success. It is about 40 plus years of competing perspectives of how best to acquire that expertise and their shaping effects. It is about technology choices amidst cultural and political conflict. It is about how budget, users, infrastructure, existing and emerging technologies, identity and geography all interrelate as elements within the technology of expertise development. Finally, it is about how at various times in the evolution of the Defense Acquisition University the technologies of tacit knowledge transfer have been elevated or diminished.

    Administrators' Perceptions of Using Social Media as a Tool for Learning
    Rossini, Elizabeth Mary (Virginia Tech, 2016-09-01)
    The purpose of this study was to investigate administrators' perceptions of using social media as a tool for learning. A review of literature revealed a disconnect between the technology students rely on outside of school versus what they use and have access to during school and leads to us to question if social media can be used as a tool for learning. The anytime, anywhere access to people, information, creation and collaboration is commonplace for these students. The challenge for principals is to lead programs that effectively educate today's youth in ways that engage them and cause significant learning. A critical review of the previous research demonstrated that technology leadership focusing on social media use for learning has gained attention in the literature mostly at the college level; the K-12 administrator level has not been widely studied. A mixed method study of K-12 administrators from across the United States was conducted to include survey and interview research. Principals and assistant principals were identified and asked to complete a survey to determine their perceptions of using social media as a tool for learning. Six follow-up interviews were conducted to examine their perceptions more deeply. This study revealed that principals and assistant principals perceived social media as a viable tool for learning; however, they indicated a need for clear social media use policies/parameters and professional learning in how to effectively engage with social media for learning. This study yielded valuable information regarding administrators' perceptions of using social media as a tool for learning that can be used in future research, policy development and professional development.

    Boundarywalkers: conceptualizing the dynamics of equitable science between Indigneous and Western knowledge
    Johnson, Cheri Lynn (Virginia Tech, 2025-02-04)
    Through interviews with Western educated scientists who also identify as Indigenous tribal members, this study seeks to understand how two knowledge systems, Indigenous Knowledge Systems (IKS) and Western Science Knowledge Systems (WSKS) can cogenerate knowledge. Interviewees for this study, as primary sources, contributed to the construction of a new concept, the boundarywalker framework, that conceptualizes the dynamics of equitable science between the knowledge systems through several key principles that promote inclusivity, mutual respect, and collaborative knowledge cogeneration. By bridging these distinct epistemic worlds, the boundarywalker framework facilitates equitable dialogue and challenges structural injustices that have historically marginalized Indigenous perspectives. This study addresses the challenges and possibilities of equitable knowledge cogeneration, where both knowledge systems contribute uniquely while retaining their distinct values. Through in-depth analysis of boundarywalker practices, the research highlights two foundational principles: epistemic pluralism, which fosters the coexistence and mutual enrichment of diverse worldviews, and epistemic revolution, which seeks to democratize the frameworks of knowledge production by centering marginalized voices and advancing reflexive justice. This involves a continuous re-evaluation of inclusivity, ensuring research methodologies and priorities are shaped by Indigenous perspectives. The boundarywalker framework offers a pathway toward an ethical, pluralistic, and reflexive science, where IKS and WSKS cogenerate knowledge as equal partners. Through epistemic pluralism and democratized framesetting, the boundarywalker framework envisions a science that honors diverse epistemologies, advances sustainable knowledge production, and strengthens the resilience of both scientific and Indigenous communities.

    Co-production of Science and Regulation: Radiation Health and the Linear No-Threshold Model
    Tontodonato, Richard Edward (Virginia Tech, 2021-06-15)
    The model used as the basis for regulation of human radiation exposures in the United States has been a source of controversy for decades because human health consequences have not been determined with statistically meaningful certainty for the dose levels allowed for radiation workers and the general public. This dissertation evaluates the evolution of the science and regulation of radiation health effects in the United States since the early 1900s using actor-network theory and the concept of co-production of science and social order. This approach elucidated the ordering instruments that operated at the nexus of the social and the natural in making institutions, identities, discourses, and representations, and the sociotechnical imaginaries animating the use of those instruments, that culminated in a regulatory system centered on the linear no-threshold dose-response model and the As Low As Reasonably Achievable philosophy. The science of radiation health effects evolved in parallel with the development of radiation-related technologies and the associated regulatory system. History shows the principle of using the least amount of radiation exposure needed to achieve the desired effect became established as a social convention to help avoid inadvertent harm long before there was a linear no-threshold dose-response model. Because of the practical need to accept some level of occupational radiation exposure, exposures from medical applications of radiation, and some de minimis exposure to the general public, the ALARA principle emerged as an important ordering instrument even before the linear no-threshold model had gained wide support. Even before ALARA became the law, it had taken hold in a manner that allowed the nuclear industry to rationalize its operations as representing acceptable levels of risk, even though it could not be proven that the established exposure limits truly precluded harm to the exposed individuals. Laboratory experiments and epidemiology indicated that a linear dose-response model appeared suitable as a "cautious assumption" by the 1950s. The linear no-threshold model proved useful to both the nuclear establishment and its detractors. In the hands of proponents of nuclear technologies, the model predicted that occupational exposures and exposures to the public represented small risks compared to naturally occurring levels of radiation and other risks that society deemed acceptable. Conversely, opponents of nuclear technologies used the model to advance their causes by predicting health impacts for undesirable numbers of people if large populations received small radiation exposures from sources such as fallout from nuclear weapon testing or effluents from nuclear reactor operations. In terms of sociotechnical imaginaries, the linear no-threshold model was compatible with both of the dominant imaginaries involved in the actor-network. In the technocratic imaginary of institutions such as the Atomic Energy Commission, the model served as a tool for qualified experts to make risk-informed decisions about applications of nuclear technologies. In the socially progressive imaginary of the citizen activist groups, the model empowered citizens to formulate arguments informed by science and rooted in the precautionary principle to challenge decisions and actions by the technocratic institutions. This enduring dynamic tension has led to the model retaining the status of "unproven but useful" even as the underlying science has remained contested.

    Fair Plastics: Advancing Industrial Decarbonization through Equitable Social Innovations
    Breslau, Daniel; McMillan, Colin; Schmid, Sonja; Tsou, Tsung-Yen (The Department of Science, Technology, and Society, Virginia Tech, 2024-08-19)
    Industrial decarbonization is an absolute and immediate requirement in the context of global climate change. Producing the basic materials that constitute the infrastructure of our modern societies (e.g. steel, cement, plastics) is the most significant source of industrial greenhouse gas (GHG) emissions. However, compared to areas such as electricity generation and ground transportation, where clear technological solutions for decarbonization have emerged, decarbonizing industry may follow any number of potential pathways. The Fair Plastics workshop brought together a group of experts and stakeholders from industry, government, research organizations, and environmental and community groups to discuss each group’s views of the significant obstacles and potential pathways of decarbonizing ethylene production. Industry representatives focused on technical pathways to ethylene decarbonization. While requesting infrastructure for electricity, hydrogen, and carbon dioxide, they emphasized the need for regulatory standards, carbon pricing, and government intervention to support the transition to decarbonization. Government and academic researchers assessed the existing pathways and highlighted carbon contributors other than ethylene, such as the steel and cement industries. The group also highlighted the economic challenges of the entire plastics lifecycle, noting the difficulty in reducing reliance on low-cost natural gas and the lack of replacement materials for ethylene-derived products. Environmental and community groups also took a lifecycle perspective and stressed the importance of addressing not only ethylene production, but also upstream and downstream activities to mitigate environmental and health impacts. They advocated for source reduction and greater industry accountability to ensure environmental justice for communities affected by petrochemical pollution. The report concludes that achieving ethylene decarbonization requires coordinated efforts across technical, social, and policy dimensions, with a focus on sustainability, innovation, and equity for affected communities.

    From Nonproliferation to Counterterrorism and Beyond:  U.S. Foreign Policy, Global Governance  and the Evolution of the Nuclear Security Regime
    Johnson, Craig Michael (Virginia Tech, 2023-02-08)
    This dissertation examines the formation and evolution of the nuclear security regime (NSR) which governs programs, policies and norms associated with the protection of nuclear and radiological materials that sub-state groups might seek to acquire for use in a terrorist attack. The regime is unique in the security field in that it is an ad hoc, voluntary structure that more closely resembles regimes associated with environment protection than the institutionalized, internationally negotiated treaties and alliances that are typical of regimes governing national security affairs. The dissertation reviews how the NSR developed over 16 years and spanned U.S presidential administrations with generally opposing approaches to multilateral cooperation and global governance. It is divided into five chapters that describe the regime; places its development within the academic context of regime theory and multilateral cooperation; traces the regime's evolution from nonproliferation efforts to counterterrorism ones; looks at the specific approaches enacted by the George W. Bush and Barack H. Obama administrations; and concludes with observations on the regime's continued longevity.

    The Fusion Enterprise Paradox: The Enduring Vision and Elusive Goal of Unlimited Clean Energy
    Eulau, Melvin L. (Virginia Tech, 2020-01-23)
    In an age of shrinking research and development (RandD) budgets, sustaining big science and technology (SandT) projects is inevitably questioned by publics and policy makers. The fusion enterprise is an exemplar. The effort to develop a viable system to produce unlimited and environmentally benign electricity from fusion of hydrogen isotopes has been a goal for six decades and consumed vast financial and intellectual resources in North America, Europe, and Asia. In terms of prolonged duration and sustained resource investment, the endeavor has developed into a huge fusion enterprise. Yet, no practical system for the generation of electricity has yet been demonstrated. This is the paradox at the heart of the fusion enterprise. Why, despite unfulfilled visions and broken promises, has the grand fusion enterprise endured? How can such a long-term enterprise persist in a funding culture that largely works in short-term cycles? Adapting Sheila Jasanoff's thesis of "sociotechnical imaginaries", I examine the relationship of shared and contrasting visions, co-produced expressions of nature and society, and distinctpolitical cultures in the quest for viable fusion. A systematic cultural and technological comparison of three fusion ventures, the National Spherical Torus Experiment Upgrade, the International Thermonuclear Experimental Reactor (ITER), and Wendelstein-7X, exposes how these projects and the institutions they inhabit frame the goals, risks, and benefits of the fusion enterprise and sustain a common set of fusion imaginaries. Positioned within the Princeton Plasma Physics Laboratory in the United States, the international ITER Organization sited in France, and the Max Planck Institute for Plasma Physics in Germany, the three projects are prime examples of big science and technology. Rigorous research and analysis of these cases advance the thesis of the unfulfilled utopian vision of fusion energy that has endured for more than sixty years.

    Imagining an Astronaut: Space Flight and the Production of Korea's Future
    Chung, Seungmi (Virginia Tech, 2020-06-26)
    This dissertation examines the debates and discourses surrounding the Korean Astronaut Program (KAP) using the concepts of sociotechnical imaginaries, sociotechnical vanguards, and the construction of expertise. Based on documentary analysis and oral interviews, this research considers KAP as an example of how the visions of sociotechnical vanguards conflict and their failure to construct a unified sociotechnical imaginary. Furthermore, it contends that the expertization of the Korean astronaut failed because of the public openness of KAP. KAP was proposed by the Ministry of Science and Technology (MOST) and run by the Korea Aerospace Research Institute (KARI). These two sociotechnical vanguards, MOST and KARI, provided different visions to the Korean public sphere, which already ascribed to its own image of an astronaut. MOST imagined the future Korea as a science-loving nation in which especially the next generations would have a strong interest in science and technology. Thus, MOST defined KAP as a science popularizing program and the Korean astronaut as a science popularizer. However, imagining a better Korea with better science and technology, KARI defined KAP as a research program that would lead to human space flight technology and considered the Korean astronaut a space expert. However, in the Korean public sphere, the widely shared expectation was a better Korea with a Korean heroic astronaut, because having a hero similar to that in other countries could position Korea on par with other advanced countries. These three visions conflicted in Korean society during KAP, and none of them succeeded in becoming the dominant sociotechnical imaginary. This elicited severe criticism of KAP and the Korean astronaut. KAP was also a good example of expertization with public openness. Credibility is the most important part of modern scientific practice. Without credibility, scientific experts cannot exercise their authority. Credibility rests on social markers such as academic degrees, track records, and institutional affiliation. However, these social markers are not suddenly assigned to an expert, who spends much time and effort attaining them. Rather, experts are made in a continuous process of improvement. Therefore, this research focuses on the process through which a person becomes an expert in emerging science and proposes the new terminology: expertization. Usually, the expertization process is hidden behind a public image. People do not know how experts obtain social markers, despite believing that these verify expertise. However, when the expertization process open to the public, it could be easily destroyed. KARI tried to position the Korean astronaut as a space expert. The first Korean astronaut did not become an expert overnight, but emerged as such to the Korean public through a selection process, training, and spaceflight. However, unlike other expertization, all steps comprising KAP were broadcast, and the expertization of Dr. Soyeon Yi, the first Korean astronaut, was open to the public. Consequently, her expertise was questioned each time the public found an element that did not satisfy their expectations. This research also clarifies the meaning of gender in emerging science. Dr. Soyeon Yi became the first Korean astronaut before any Korean male. In this way, KAP provided an important meaning to women in science, especially in the field of emerging science, which is usually dominated by males. Through these discussions, this research expands the application of sociotechnical imaginary and expert studies. It also enhances understanding of these discourses in Korean society, and stimulates discussions of the negative consequences of research programs.

    Improving Water Security with Innovation and Transition in Water Infrastructure: From Emergence to Stabilization of Rainwater Harvesting in the U.S.
    Reams, Gary A. (Virginia Tech, 2021-11-12)
    Globally, two-thirds of the population face significant water shortages and eighty percent of the U.S. states' water managers predict water shortages in the near future. Additionally, the current centralized system in the United States is facing significant problems of scarcity, groundwater depletion, high energy consumption and needs a trillion dollars investment in repairs, replacement, and expansion. Furthermore, due to increased urban/suburban development, runoff (stormwater) pollutes our waterways and is causing increased flooding. The status quo is unsustainable in its present form and the water security of the nation is at risk. Fortunately, in recent decades there has been a resurgence in the use of a millenniums old approach, rainwater harvesting (RWH), that if deployed broadly, will mitigate those issues created by the current centralized municipal water system and the expanding development of our cities, suburbs, and towns reducing permeable surface area and lower water security vulnerabilities. This study enlists Multi-Level Perspective (MLP) to examine the transitioning that is occurring from the current centralized municipal water system to one in which it is significantly complemented by an alternative water source, RWH. MLP posits that pressures originating in the broader landscape exerts pressures on the existing regime, as well as the community as a whole, creating an opportunity for the niche to emerge and either replace or change the regime. In the case of RWH, the myriad of pressures are only partially placed on the current centralized water supply regime providing them less pressure to change. Alongside water shortages another significant pressure being placed on the public and governing authorities is increased flooding and pollution resulting in the RWH niche emerging in the construction industry. In response to these pressures a RWH niche formed, largely outside of the existing water supply regime, and grew until it was joined by actors within the regime (e.g., plumbers, plumbing engineers, standards development organizations). This research is framed using MLP's three phases Start-up (niche), Acceleration, and Stabilization. This dissertation does three things. First it shows the internal processes occurring between the MLP levels (landscape, sociotechnical regime, and niche) and mechanisms created that foster the broader adoption of RWH. Secondly, it reveals that while the incumbent regime is not being significantly influenced by the RWH niche, the construction industry is embracing RWH (especially the commercial sector) and following the MLP pathway of Reconfiguration. Third, it looks at RWH in a phase of stabilization.

    Maintaining the Atom: U.S. Nuclear Power Plant Life and the 80-Year Maintenance Regulation Regime
    Miller, Daniel Paul (Virginia Tech, 2020-01-22)
    Large, ever more complex, technological systems surround us and provide products and services that both construct and define much of what we consider as modern society. Our societal bargain is the trade-off between the benefits of our technologies and our constant vigilance over the safe workings and the occasional failures of these often hazardous sociotechnical systems during their operating life. Failure of a system's infrastructure, whether a complex subsystem or a single component, can cause planes to crash, oil rigs to burn, or the release of radioactivity from a nuclear power plant. To prevent catastrophes, much depends not only on skilled and safe operations, but upon the effective maintenance of these systems. Using the commercial nuclear power industry, of the United States, as a case study, this dissertation examines how nuclear power plant maintenance functions to ensure the plants are reliable and can safely operate for, potentially, eighty years; the current, government regulation defined limit, of their functional life. This study explores the history of U.S. nuclear maintenance regulatory policy from its early Cold War political precursors, the effect of the 1979 Three Mile Island reactor melt-down accident, through its long development, and finally its implementation by nuclear power licensees as formal maintenance programs. By investigating the maintenance of nuclear power plants this research also intends to expand the conceptual framework of large- technological-system (LTS) theory, in general, by adding a recognizable, and practically achievable, end-of-life (EOL) phase to the heuristic structure. The dissertation argues that maintenance is a knowledge producing technology that not only keeps a sociotechnical system operating through comprehension, but can be a surveillance instrument to make system end-of-life legible; that is both visible and understandable. With a discernible and legible view of system end-of-life, operators, policy makers, and the public can make more informed decisions concerning a system's safety and its continued usefulness in society.

    Making and Breaking Big Rural: Science and Technology Construct the Coalfield
    Cook Marshall, Crystal A. (Virginia Tech, 2018-01-25)
    Making and Breaking Big Rural: Science and Technology Construct the Coalfield examines science and technology research and its role in constructing a rural industrial space such as the Pocahontas Coalfield in Southern West Virginia/Southwest Virginia. It examines the ramifications of this single sector rural space, and of automation and coalfield technology, on its inhabitants, especially on their capacity for democratic practice. In a call for science and research for public benefit, it proposes how scientific and technological research ought to engage with the people and the environment in this rural industrial space, and in the rural space more generally. Using a case study of the Pocahontas Coalfield as a springboard, a draft of a National Rural Strategy for the United States also is proposed.

    Merchant Marine Deck Officer Agency Through Performative Acts
    Clark, Donald (Virginia Tech, 2016-09-06)
    I bring together ethnographic interviews with deck officers, studies in actor-network theory, explicit and tacit knowledge theory, and performativity theory in this work. I prove that bridge technologies produce what are called mimeomorphic (repeatable with some variation) actions that contain no deck officer collective tacit knowledge. I argue that deck officer bridge watch situated actions are mostly polimorphic (actions can vary depending on social context), and these actions are in fact performatives (in an Austin sense) derived from a more oral than literate performance production process. These performatives constantly build the mariner's identity within the maritime deck officer community and their successful performatives give deck officers agency in the form of an oppositional view to deskilling. These same performative acts are the value of the mariner's experiential technological knowledge within the ship's bridge technology framework.

    The Oil Weapon Moment: The 1973 Oil Embargo and its Impacts on U.S. Energy Politics
    Atalla, Basil George (Virginia Tech, 2025-01-09)
    This dissertation examines the impacts of the 1973 Arab petrostate oil embargo on U.S. energy politics. I argue that the embargo was the moment that transformed oil from a domestic and highly regulated commodity into a matter of national security and competitive geopolitics. While its likelihood was foreseen by the Nixon Administration, the embargo did exacerbate an existing energy crisis that was caused by pre-embargo federal energy policies. Following the embargo, a dominant narrative emerged that viewed dependence on foreign oil supplies as an existential threat that merited extraordinary government measures. The securitization of the energy crisis allowed the Nixon Administration to implement many of its pre-embargo energy policies, including the launch of a national energy program to bring the U.S. to energy self-sufficiency by 1980. The embargo was the trigger for the creation of new governmental entities, such as the Department of Energy and U.S. Central Command, that endure to this day. It also shaped the U.S.'s close relationship with Saudi Arabia as an essential oil supplier and a key ally in the Arab world. The dissertation contests the revisionist accounts that argue that the embargo was a non-event, arguing that its impacts on U.S. domestic and foreign policies are still tangible and relevant.

    Producing Knowledge about Astronaut Health Risks: Navigating Interdisciplinary Actor-Networks
    Morton, Stephen Gerard (Virginia Tech, 2023-06-07)
    When astronauts return from a space mission they smile for the cameras, but behind the scenes they undergo grueling rehab to recover from the effects of space and may face long-term health consequences. Space flights lasting more than thirty days are considered long-duration and may impact astronauts' long-term health due to space exposure; this requires the National Aeronautics and Space Administration to develop new scientific, medical, and space operational knowledge to counteract and mitigate harmful effects. Understanding how knowledge production occurs is an important analytical and policy issue at NASA. This dissertation explores knowledge production about astronaut health risks using structured and unstructured interviews conducted at Johnson Space Center, the home of mission control for NASA. Applied Actor-Network Theory using a stage analysis shows how various human and non-human actors create this knowledge, constructing, combining, and passing facts across disciplinary boundaries about health risks. A normative analysis of informant statements demonstrates how knowledge and values regarding their understanding of long-term astronaut health risks impact the actions and policies developed at NASA. Steven Hilgartner (1992) suggests that risk research has done very little examination of the social construction of risk objects. He further suggests (1992) that studies fail to systematically examine the construction of causal attribution networks that link chains of risk objects to harm. (Hilgartner, 1992, p. 40-41) This study remedies that lack concerning space medicine by filling in the intellectual, social, and institutional processes that link space flight characteristics to physical harms.

    Sharing the Shuttle with America: NASA and Public Engagement after Apollo
    Kaminski, Amy Paige (Virginia Tech, 2015-03-30)
    Historical accounts depict NASA's interactions with American citizens beyond government agencies and aerospace firms since the 1950s and 1960s as efforts to 'sell' its human space flight initiatives and to position external publics as would-be observers, consumers, and supporters of such activities. Characterizing citizens solely as celebrants of NASA's successes, however, masks the myriad publics, engagement modes, and influences that comprised NASA's efforts to forge connections between human space flight and citizens after Apollo 11 culminated. While corroborating the premise that NASA constantly seeks public and political approval for its costly human space programs, I argue that maintaining legitimacy in light of shifting social attitudes, political priorities, and divided interest in space flight required NASA to reconsider how to serve and engage external publics vis-à-vis its next major human space program, the Space Shuttle. Adopting a sociotechnical imaginary featuring the Shuttle as a versatile technology that promised something for everyone, NASA sought to engage citizens with the Shuttle in ways appealing to their varied, expressed interests and became dependent on some publics' direct involvement to render the vehicle viable economically, socially, and politically. NASA's ability and willingness to democratize the Shuttle proved difficult to sustain, however, as concerns evolved following the Challenger accident among NASA personnel, political officials, and external publics about the Shuttle's purpose, value, safety, and propriety. Mapping the publics and engagement modes NASA regarded as crucial to the Shuttle's legitimacy, this case study exposes the visions of public accountability and other influences -- including changing perceptions of a technology -- that can govern how technoscientific institutions perceive and engage various external publics. Doing so illuminates the prospects and challenges associated with democratizing decisions and uses for space and, perhaps, other technologies managed by U.S. government agencies while suggesting a new pathway for scholarly inquiry regarding interactions between technoscientific institutions and external publics. Expanding NASA's historical narrative, this study demonstrates that entities not typically recognized as space program contributors played significant roles in shaping the Shuttle program, substantively and culturally. Conceptualizing and valuing external publics in these ways may prove key for NASA to sustain human space flight going forward.

    To Err on the Side of Caution: Ethical Dimensions of the National Weather Service Warning Process
    Henderson, Jennifer J. (Virginia Tech, 2017-01-05)
    This dissertation traces three ethical dimensions, or values, of weather warnings in the National Weather Service (NWS): an ethic of accuracy, and ethic of care, and an ethic of resilience. Each appear in forecaster work but are not equally visible in the identity of a forecaster as scientific expert. Thus, I propose that the NWS should consider rethinking its science through its relationship to multiple publics, creating what Sandra Harding calls "strong objectivity." To this end, I offer the concept of empathic accuracy as an ethic that reflects the interrelatedness of precision and care that already attend to forecasting work. First, I offer a genealogy of the ethic of accuracy as forecasters see it. Beginning in the 1960s, operational meteorologists mounted an ethic of accuracy through the "man-machine mix," a concept that pointed to an identity of the forecasting scientist that required a demarcation between humans and technologies. It is continually troubled by the growing power of computer models to make predictions. Second, I provide an ethnographic account of the concern expressed by forecasters for their publics. I do so to demonstrate how an ethic of care exists alongside accuracy in their forecasting science, especially during times of crisis. I recreate the concern for others that their labor performs. It is an account that values emotion and is sensitive to context, showing what Virginia Held calls "the self-and-other together" that partially constitutes a forecaster identity. Third, I critique the NWS Weather Ready Nation Roadmap and its emphasis on developing in the public an ethic of resilience. I argue that, as currently framed, this ethic and its instantiation in the initiative Impact Based Decision Support Services narrowly defines community to such an extent that it disappears the public. However, it also reveals other valences of resilience that have the potential to open up a space for an empathetic accuracy. Finally, I close with a co-authored article that explores my own commitment to an ethic of relationality in disaster work and the compromises that create tension in me as a scholar and critical participant in the weather community.

    Transhumanism-Christianity Diplomacy:  To Transform Science-Religion Relations
    Winyard Sr, David C. (Virginia Tech, 2016-11-18)
    Transhumanism is an emerging philosophical and social movement that aims, through technology, to extend human life and radically expand intellectual, physical, and psychological capabilities. Many of transhumanism's goals overlap the eschatological hopes of Christians, such as the elimination of sickness and death. Yet observers who see transhumanism and Christianity in monolithic terms often portray them as adversaries. Against this view, I argue that within each community are factions that have comparable, but contested, views on God, the divine attributes, and human origins, responsibility, and destiny. As a result, an emerging dialog between particular transhumanists and Christians seeks to shape the future of humanity by integrating the basic commitments of transhumanism and Christianity. Bruno Latour's concept of modes of existence offers a framework for both developing and analyzing diplomacy between and within Christian and transhumanist communities. Specifically, Latour's work allows for the identification of category mistakes that set the terms of intermodal conflicts and dialog. Some transhumanists and most Christians hold beliefs about the nature and meaning of God. Christians believe in a Trinitarian God that is the preexistent, eternal, and personal creator of the universe. By contrast, elements of the transhumanist movement believe that in the future an artificial God will inevitably emerge as an omniscient and omnipotent supercomputer. The attributes, concepts and purposes of God and, by extension, nature lend a basis for developing diplomatic relationships between factions of transhumanism and Christianity. Diplomacy between transhumanism and Christianity exists via social media and virtual meeting places. At the forefront of this movement is a new Christian Transhumanist Association that I analyze in some depth. It is only a couple of years old, but its leaders have already attracted international attention. Their strategy of theological minimalism seeks to reduce friction among stakeholders. I show that this strategy sacrifices the insights that Christian theology and philosophy could bring to the development of transhumanism. I conclude that in order to affect transhumanism Christians must find ways to apply their insights into personal creator-creature relationships to the challenges of safely developing artificial superintelligence.

    Tritium Matters: Constructing Nuclearity and Navigating Ambivalence of a Unique Material
    Loy, Taylor Andrew (Virginia Tech, 2024-07-10)
    This dissertation surveys the history of tritium beginning in Ernest Rutherford's lab in 1934 with its discovery and ending at the Fukushima Daiichi disaster site in 2023 when TEPCO began releasing tritiated wastewater into the Pacific ocean. In this time, expert conceptions of tritium have experienced interdependent and overlapping phases. Each phase is characterized by a dominant "nuclearity" and situated in context of "nuclear exceptionalism" (Hecht 2014) that directly and indirectly affects material conditions, elite decision-making, and radiological impacts on the environment and human health. Because it is pervasive, diffuse, and laborious to measure, a great deal of uncertainty surrounds tritium's contribution to radiological risks. Beyond various commercial and scientific uses, it is also integral to both nuclear energy as a waste and nuclear weapons as a mechanism for dramatically increasing explosive yields. This versatile and powerful material operates at the technological nexus of two existential risks for humanity: climate change and nuclear weapons. I divide the history of tritium into three distinct phases. First, super nuclearity characterizes early designs for the "superbomb" by Manhattan project scientists who believed vast amounts of tritium would be required. This phase extends to the late 1950s when thermonuclear warheads based on more feasible designs requiring significantly less tritium were beginning to be incorporated into the U.S. nuclear weapon stockpile. Second, special nuclearity describes the status of tritium throughout the Cold War as a critical nuclear weapons material that was referred to and treated as a special nuclear material (SNM) in practice even though it was never legally defined as such. Third, byproduct nuclearity is the current post-Cold War paradigm defining tritium as a form of incidental waste or as an innocuous "other accountable material" intentionally produced by the nuclear fission process. While tritium's super nuclearity proved to be an animating fiction with political and material impacts on the early U.S. post war nuclear weapons program, tritium's special and byproduct nuclearities have since been fully embodied in technological artifacts—primarily nuclear weapons and nuclear power plants—and remain in dynamic tension. Tritium does not fit neatly into existing nuclearity narratives. It is accurately referred to as both "highly" and "weakly" radioactive. Having a half-life of ~12 years and being the lightest radioisotope, it has high activity by weight, but when it decays into stable helium-3 it emits only a relatively weak beta particle which poses a potential risk as internal dose. I argue that the nuclearity processes constituting various conceptualizations of tritium provide insight into navigating the complex sociotechnical relationships between humans and nuclear technology. Additionally, I anticipate tritium's next nuclearity transformation as reactor fuel for a still nascent fusion power industry. I argue that rather than allowing fusion energy proponents to dictate the next phase of tritium's nuclearity, efforts should be made to assess and synthesize salient aspects of this unique material to provide a more holistic accounting of its risks, benefits, and tradeoffs.
