Description
To address the need of scientists and engineers in the United States workforce and ensure that students in higher education become scientifically literate, research and policy has called for improvements in undergraduate education in the sciences. One particular pathway for improving undergraduate education in the science fields is to reform undergraduate teaching. Only a limited number of studies have explored the pedagogical content knowledge of postsecondary level teachers. This study was conducted to characterize the PCK of biology faculty and explore the factors influencing their PCK. Data included semi-structured interviews, classroom observations, documents, and instructional artifacts. A qualitative inquiry was designed to conduct an in-depth investigation focusing on the PCK of six biology instructors, particularly the types of knowledge they used for teaching biology, their perceptions of teaching, and the social interactions and experiences that influenced their PCK. The findings of this study reveal that the PCK of the biology faculty included eight domains of knowledge: (1) content, (2) context, (3) learners and learning, (4) curriculum, (5) instructional strategies, (6) representations of biology, (7) assessment, and (8) building rapport with students. Three categories of faculty PCK emerged: (1) PCK as an expert explainer, (2) PCK as an instructional architect, and (3) a transitional PCK, which fell between the two prior categories. Based on the interpretations of the data, four social interactions and experiences were found to influence biology faculty PCK: (1) teaching experience, (2) models and mentors, (3) collaborations about teaching, and (4) science education research. The varying teaching perspectives of the faculty also influenced their PCK. This study shows that the PCK of biology faculty for teaching large introductory courses at large research institutions is heavily influenced by factors beyond simply years of teaching experience and expert content knowledge. Social interactions and experiences created by the institution play a significant role in developing the PCK of biology faculty.

Description
This dissertation investigates how ideas of the right relationships among science, the public, and collective decision-making about science and technology come to be envisioned in constructions of public engagement. In particular, it explores how public engagement has come to be constructed in discourse around gene editing to better understand how it holds together with visions for good, democratic governance of those technologies and with what effects. Using a conceptual idiom of the co-production of science and the social order, I investigate the mutual formation of scientific expertise, responsibility, and democracy through constructions of public engagement. I begin by tracing dominant historical narratives of contemporary public engagement as a continuation of public understanding of science’s projects of social ordering for democratic society. I then analyze collections of prominent expert meetings, publications, discussions, and interventions about development, governance, and societal implications human heritable germline gene editing and gene drives that developed in tandem with commitments to public engagement around those technologies. Synthesizing the evidence from across gene editing discourse, I offer a constructive critique of constructions of public engagement as expressions and evidence of scientific responsibility as ultimately reasserting and reinforcing of scientific experts' authority in gene editing decision-making, despite intentions for public engagement to extend decision-making participation and power to publics. Such constructions of public engagement go unrecognized in gene editing discourse and thereby subtly reinforce broader visions of scientific expertise as essential to good governance by underwriting the legitimacy and authority of scientific experts to act on behalf of public interests. I further argue that the reinforcement of scientific expert authority in gene editing discourse through public engagement also centers scientific experts in a sociotechnical imaginary that I call “not for science alone.” This sociotechnical imaginary envisions scientific experts as guardians and guarantors of good, democratic governance. I then propose a possible alternatives to public engagement alone to improve gene editing governance by orienting discourse around notions of public accountability for potential shared benefits and collective harms of gene editing.

Description
This dissertation investigates the relationship between the universal aspirationsof technology and the particularity of place, by way of close participant observation with biotechnology companies in the San Francisco Bay Area. Its central claim is that the aspiration to placelessness in the development of science and technology operates as material configurations, modes of subjectivation, and historical conditions particular to places. Following Foucault’s late work in ethics, I conduct a series of sustained investigations into the reflective modes of critique biotechnologists make in thinking of and being in the San Francisco Bay Area. I show the ways the aspiration to placelessness exists in place at four different vantage points: the organization, the city, the broader cultural history of the region, and the practices of self-cultivation undertaken by technologists. Within biotechnology organizations, biological work is digitized and automated only through an intensification of bespoke material infrastructures, physical labor, and tacit institutional knowledge. Biotechnology organizations have come into existence through a history of settler colonial erasure, industrial devastation, post-war industrial decay, and urban renewal in Bay Area industrial suburbs and neighborhoods. A nostalgic imagination of the broader San Francisco Bay Area and its history of counterculture become mobilized as an antidote to the felt lifelessness of these forms of urban renewal and technological order and incorporated back into engineering practice. Finally, the technologist themselves must aspire to placelessness, in ways critiqued by local landless people’s movements who offer an alternative ethic to place in their imperative to gentrifiers to “move home with your parents.” I conclude by reflecting on the ways interlocutors at each of these vantage points are actively exploring the creation of more enduring relationships to place in the face of the unintended but intensified forms of social suffering in zones of technological innovation.

Description
Writing speculative fiction is a valuable method for exploring the potential societal transformations elicited by advances in science and technology. The aim of this project is to use speculative fiction to explore the potential consequences of precision medicine for individuals’ daily lives. Precision medicine is a vision of the future in which medicine is about predicting, and ultimately preventing disease before symptoms arise. The idea is that identification of all the factors that influence health and contribute to disease development will translate to better and less expensive healthcare and empower individuals to take responsibility for maintaining their own health and wellness. That future, as envisioned by the leaders of the Human Genome Project, the Institute for Systems Biology, and the Obama administration’s Precision Medicine Initiative, is assumed to be a shared future, one that everyone desires and that is self-evidently “better” than the present. The aim of writing speculative fiction about a “precision medicine” future is to challenge that assumption, to make clear the values underpinning that vision of precision medicine, and to leave open the question of what other possible futures could be imagined instead.

Description
Over the last few hundred years, best practice in some fields of human action—e.g., the treatment of heart disease, the transportation of persons, goods, and messages, and the destruction of landscapes, structures, and lives—has become dramatically more effective. At the same time, best practice in other fields, e.g., the amelioration of poverty or the teaching of reading, writing, or math, has improved more slowly, if at all. I argue that practice and technology (“know-how”) can only improve rapidly under rather special conditions: that, at any given point in time, some fields are more “progressible” than others.I articulate a conceptual framework describing several characteristics of practice in a field that may facilitate rapid progress. These characteristics, while not fixed, tend to remain fairly stable for long periods of time. I argue that know-how can improve more quickly 1) when offline “vicarious trial” of variations in practice is feasible and useful; 2) when practice is formal and standardized; 3) when practice is substantially performed by artifacts rather than by humans; 4) when outcomes of variations in practice may be rapidly evaluated; 5) when goals of practice are consistently agreed upon; 6) when contexts and objects of practice may be treated as, or have been made, consistent for the purposes of intervention; 7) when components of task systems are not heavily interdependent; and 8) when labor is finely and sharply divided.
I illustrate and elaborate this framework through comparative case studies on efforts to improve practice in three differentially “progressible” fields. I examine rapid improvement in a COVID-19 testing lab, inconsistent improvement in undergraduate algebra instruction, and ambiguous improvement in regional water modeling to support municipal water management. These cases indicate that my theory may inform judgments about the plausibility of rapid advance within a field of practice, absent disruptive change in methods or problem formulation. My theory may also shed light on which varieties of innovative effort may and may not foreseeably contribute to improving practice in a given field—more formal, theoretical, and context-independent work in high-progressibility domains, more tacit, grounded, and localized work in low-progressibility ones.

Description
This dissertation examines the efforts of the Carnegie Image Tube Committee (CITC), a group created by Vannevar Bush and composed of astronomers and physicists, who sought to develop a photoelectric imaging device, generally called an image tube, to aid astronomical observations. The Carnegie Institution of Washington’s Department of Terrestrial Magnetism coordinated the CITC, but the committee included members from observatories and laboratories across the United States. The CITC, which operated from 1954 to 1976, sought to replace direct photography as the primary means of astronomical imaging.
Physicists, who gained training in electronics during World War II, led the early push for the development of image tubes in astronomy. Vannevar Bush’s concern for scientific prestige led him to form a committee to investigate image tube technology, and postwar federal funding for the sciences helped the CITC sustain development efforts for a decade. During those development years, the CITC acted as a mediator between the astronomical community and the image tube producers but failed to engage astronomers concerning various development paths, resulting in a user group without real buy-in on the final product.
After a decade of development efforts, the CITC designed an image tube, which Radio Corporation of American manufactured, and, with additional funding from the National Science Foundation, the committee distributed to observatories around the world. While excited about the potential of electronic imaging, few astronomers used the Carnegie-developed device regularly. Although the CITC’s efforts did not result in an overwhelming adoption of image tubes by the astronomical community, examining the design, funding, production, and marketing of the Carnegie image tube shows the many and varied processes through which astronomers have acquired new tools. Astronomers’ use of the Carnegie image tube to acquire useful scientific data illustrates factors that contribute to astronomers’ adoption or non-adoption of those new tools.

Description
In the last 200 years, advancements in science and technology have made understanding female sexual function and the female body more feasible; however, many women throughout the US still lack fundamental understanding of the reproductive system in the twenty-first century. Many factors contribute to the lack of knowledge and misconceptions that women still have. Discussing sexual health tends to make some people uncomfortable and this study aims to investigate what aspects of somewhat recent US history in women’s health care may have led to that discomfort. This thesis examines the question: what are some of the factors that shaped women’s reproductive medicine in the US from the mid 1800s and throughout the 1900s and what influence could the past have had on how women and their physicians understand female sexuality in medicine and how physicians diagnose their female patients in the twenty-first century. A literature review of primary source medical texts written at the end of the 1800s provides insight about patterns among physicians at the time and their medical practice with female patients. Factors like gendered expectations in medical practice, misconceptions about the female body and behaviors, and issues of morality in sex medicine all contributed to women lacking understanding of sex female reproductive functions. Other factors like a physician’s role throughout history and non-medical reproductive health providers and solutions likely also influenced the reproductive medicine women received. Examining the patterns of the past provides some insight into some of the outdated and gendered practices still exhibited in healthcare. Expanding sexual education programs, encouraging discussion about sex and reproductive health, and checking gendered implicit bias in reproductive healthcare could help eliminate echoes of hysteria ideology in the twenty-first century medicine.

Description
This is a project about medicine and the history of a condition called premenstrual syndrome (PMS), its “discovery” and conceptual development at both scientific and socio-cultural levels. Since it was first mentioned in medical literature, PMS has been explored empirically as a medical condition and conceptually as non-somatic cultural phenomenon. Many attempts have been made to produce scientific, empirical evidence to bolster the theory of PMS as a biological disease. Some non-medical perspectives argue that invoking biology as the cause of PMS medicalizes a natural function of the female reproductive system and shallowly interrogates what is actually a complex bio-psycho-social phenomenon. This thesis questions both sides of this debate in order to reveal how criteria for PMS were categorized despite disagreement surrounding its etiology.
This thesis illustrates how the concept of PMS developed and was informed by the discovery of hormones and the resulting field of endocrinology that provided a framework for conceptualizing PMS. It displays how the development of the medical diagnostic category of PMS developed in tandem with the emergence of the field of endocrinology and was legitimized and effectively medicalized through this connection. The diagnosis of PMS became established though the diagnostic techniques like questionnaires in spite of persistent disagreement over its definition. The thesis shows how these medical concepts and practices legitimated the category of PMS, and how it has become ubiquitous in contemporary culture.

Description
Systems biology studies complex biological systems. It is an interdisciplinary field, with biologists working with non-biologists such as computer scientists, engineers, chemists, and mathematicians to address research problems applying systems’ perspectives. How these different researchers and their disciplines differently contributed to the advancement of this field over time is a question worth examining. Did systems biology become a systems-oriented science or a biology-oriented science from 1992 to 2013?
This project utilized computational tools to analyze large data sets and interpreted the results from historical and philosophical perspectives. Tools deployed were derived from scientometrics, corpus linguistics, text-based analysis, network analysis, and GIS analysis to analyze more than 9000 articles (metadata and text) on systems biology. The application of these tools to a HPS project represents a novel approach.
The dissertation shows that systems biology has transitioned from a more mathematical, computational, and engineering-oriented discipline focusing on modeling to a more biology-oriented discipline that uses modeling as a means to address real biological problems. Also, the results show that bioengineering and medical research has increased within systems biology. This is reflected in the increase of the centrality of biology-related concepts such as cancer, over time. The dissertation also compares the development of systems biology in China with some other parts of the world, and reveals regional differences, such as a unique trajectory of systems biology in China related to a focus on traditional Chinese medicine.
This dissertation adds to the historiography of modern biology where few studies have focused on systems biology compared with the history of molecular biology and evolutionary biology.

Scientific and Cultural Interpretations of Volcanoes, 1766-1901 analyzes nineteenth-century conceptions of volcanoes through interdisciplinary literature and science studies. The project considers how people in the nineteenth century used science, aesthetics, and other ways of knowing to understand volcanoes and their operations. In the mid-eighteenth century, volcanoes were seen as singular, unique features of the planet that lacked temporal and terrestrial reach. By the end of the nineteenth century, volcanoes were seen as networked, environmental phenomena that stretched through geological time and geographic space. Scientific and Cultural Interpretations of Volcanoes, 1766-1901 offers a new historical understanding of volcanoes and their environmental connections, using literature and science to show how perceptions of volcanic time and space changed over 135 years.
The first chapter, using texts by Sir William Hamilton, Hester Piozzi, and Priscilla Wakefield, argues that in the late eighteenth century important aspects of volcanoes, like their impact upon human life and their existence through time, were beginning to be defined in texts ranging from the scientific to the educational. The second chapter focuses on works by Sir Edward Bulwer-Lytton and Charles Lyell to demonstrate the ways that volcanoes were stripped of metaphysical or symbolic meaning as the nineteenth century progressed. The third chapter contrasts the 1883 eruption of Krakatoa with Constance Gordon-Cumming’s travels to Kīlauea. The chapter shows how even towards the end of the century, trying to connect human minds with the process of volcanic phenomenon was a substantial challenge, but that volcanoes like Kīlauea allowed for new conceptions of volcanic action. The last chapter, through a post-apocalyptic novel by M. P. Shiel, shows how volcanoes were finally beginning to be categorized as a primary agent within the environment, shaping all life including humanity. Ultimately, I argue that the change in thinking about volcanoes parallels today’s shift in thinking about global climate change. My work provides insight into how we imagine ecological catastrophes like volcanic eruptions or climate change in the past and present and what that means for their impact on people.
