Trucking replaced railroads as the primary link between rural producers and urban consumers in the mid-twentieth century. With this technological change came a fundamental transformation of the defining features of rural life after World War II. Trucking helped drive the shift from a New Deal-era political economy-based on centralized political authority, a highly regulated farm and food economy, and collective social values-to a postwar framework of anti-statism, minimal market regulation, and fierce individualism. Trucking and rural truck drivers were at the heart of what I call the "marketing machine," a new kind of food economy that arose after World War II, characterized by decentralized food processors and supermarkets seeking high volume, low prices, and consistent quality to eliminate uncertainties from the food distribution chain. This marketing machine developed as a reaction against the statist food and farm policies of the New Deal. Government agricultural experts-economists, engineers, and policymakers-encouraged the growth of highway transportation in an effort to redefine the "farm problem" as an industrial problem, an issue to be solved by rural food processors and non-unionized "independent" truck drivers rather than price supports or acreage controls.; by Shane L.

This dissertation is an examination of intersections of race, pharmaceuticals, and heart disease over the course of the 20th century and today. Each of these parts has had a dynamic history, and when they are invoked together they provide a terrain for arguments about interventions in health and in justice in the present. An enduring aspect of discourses of heart disease over the past century has been articulating connections between characterizations of the modem American way of life and of heart disease. In that process, heart disease research and practice has participated in differentiating Americans, especially by race. This dissertation uses heart disease categories and the drugs prescribed for them as windows into racialized medicine. The chapters are organized in a way that is roughly chronological, beginning with the emergence of cardiology as a specialty just before World War II and the landmark longitudinal Framingham Heart Study that began shortly thereafter. A central chapter tracks the emergence and mobilization of African American hypertension as a disease category since the 1960s.; (cont.) Two final chapters attend to current racial invocations of two pharmaceuticals: thiazide and BiDil. Using methods from critical historiography of race...

This ethnography tracks visualization and pedagogy in the burgeoning field of structural biology. Structural biologists are a multidisciplinary group of researchers who produce models and animations of protein molecules using three-dimensional interactive computer graphics. As they ramp up the pace of structure determination, modeling a vast array of proteins, these researchers are shifting life science research agendas from decoding genetic sequence data to interpreting the multidimensional forms of molecular life. One major hurdle they face is training a new generation of scientists to work with multi-dimensional data forms. In this study I document the formation and propagation of tacit knowledge in structural biology laboratories, in classrooms, and at conferences. This research shows that structural biologists-in-training must cultivate a feel for proteins in order to visualize and interpret their activity in cells. I find that protein modeling relies heavily on a set of practices I call the body-work of modeling. These tacit skills include: a) forms of kinesthetic knowledge that structural biologists gain through building and manipulating molecular models, and by using their own bodies as mimetic models to help them figure out how proteins move and interact; and b) narrative strategies that assume a teleological relationship between form and function...

In recent years, coaching has become a major form of personal and professional development service offered to executives to help develop leadership skills, enhance performance, and remediate patterns of problematic workplace behavior. This dissertation examines the emergence and development of executive coaching in the United States as a new form of professional expertise. Drawing on eighteen months of ethnographic research, the majority of which took place in New York City, this study analyzes the ways in which executive coaching brings together theories of individual psychology and of organizational efficiency in order to increase functionality and productivity at work. Executive coaching is: a) a new form of professional expertise, b) a management tool to increase productivity and efficiency at work, c) a window to changing notions of the self and personhood in America and, finally d) an access point to the corporate world. This study explores these four dimensions of executive coaching. I argue that the emergence of coaching is a product of and a response to a fast changing business environment where continuous improvement is required to adapt to the volatility of changes. Change in the larger context (corporate settings and business environments) is not to be resisted or criticized but to be enabled through the change of the self. This dissertation illustrates and explains the grounds of a shift away from systemic approaches and systemic criticism towards individualistic approaches. Coaching emerges in and becomes an illustration of a neo-liberal economy that emphasizes constant retraining of a self that is versatile...

This dissertation recounts the development of graphic models of human bodies and virtual reality simulators for teaching anatomy and surgery to medical students, residents, and physicians. It considers how researchers from disciplinary cultures in medicine, engineering, and computer programming come together to build these technologies, bringing with them values and assumptions about bodies from each of their disciplines, values and assumptions that must be negotiated and that often are made material and embedded in these new technologies. It discusses how the technological objects being created privilege the body as a dynamic and interactive system, in contrast to the description and taxonomic body of traditional anatomy and medicine. It describes the ways that these technologies create new sensory means of knowing bodies. And it discusses the larger cultural values that these technologies reify or challenge. The methodology of this dissertation is ethnography. I consider in-depth one laboratory at a major medical school, as well as other laboratories and researchers in the field of virtual medicine. I study actors in the emerging field of virtual medicine as they work in laboratories, at conferences, and in collaborations with one another. I consider the social formations that are developing with this new discipline. Methods include participant observation of laboratory activities...

"The Soviet Farm Complex" is a history of food, farming and the environment in the postwar Soviet Union. It tells the story of how different technical and institutional authorities created an industrial Soviet countryside in the generation after World War II. Beyond the leadership of the Soviet state, international trade relationships, new technologies, unusual scientific cultures, stubborn environmental realities and human shortcomings played important roles in shaping the progress of agricultural change. Four historical fields inform this project: the history of technology, agricultural history, Soviet history and environmental history. Each of the five chapters addresses a different time, place and theme in the history of the Soviet countryside, providing a close-up view of the most important aspects of postwar rural change. Soviet agricultural reform has often been interpreted as a failure: a textbook case of poor central planning and destructive, high-modernist logic on the part of the Soviet state. In fact, this study shows that the collective farming system as a whole was not particularly dysfunctional, nor was it doomed to failure simply by virtue of being centrally planned.; (cont.) Much like the capitalist farms with which it competed...

In this dissertation, I examine how the members of a distributed software development team (LC) operating entirely virtually for four and half years developed useful social practices to collaborate across time and space. Based on various communication data from LC, I analyze the communicative structuring of distributed work in members' daily practices. I show that "temporal flexibility," often mentioned as key advantage of virtual organizing, is socially accomplished through "boundary management," as members negotiate different temporal boundaries and learn and adapt to others' temporal patterns. Second, I identify dynamic coordination practices in LC that interweave multiple modes of communication and coordination in evolving work contexts, and demonstrate how these coordination practices facilitate temporal flexibility in LC. Finally, I analyze how members used the asynchronous communication medium of email to coordinate their tasks, using the notion of genre and genre system.; (cont.) My analysis suggests that communicating, coordinating, and temporal structuring are not distinctive activities, but are closely bound up with each other in a local practice; time, communication, and coordination are dynamically reconfigured over time...

Guglielmo Marconi's trans-Atlantic wireless experiment in 1900 marked the beginning of a communication revolution that transformed the open space above the earth into channels of information flow. This dissertation grapples with the historical conditions that gave rise to such a transformation: the studies of radio-wave propagation and the treatments of radio interferences in early twentieth-century America and Western Europe. The part on propagation examines the debate between the surface diffraction theory and the atmospheric reflection theory for long waves, the development of the ionic refraction theory for short waves, the evidential quests for the existence of the ionosphere, and the studies of the geomagnetic effects on propagation. The part on interferences focuses on the engineering efforts toward the characterization of atmospheric noise and signal-intensity fluctuations, the policies of radio-channel allocation for fighting man-made interference, and the scientific research into electronic tube noise. By the mid-30s, the results from these endeavors had considerably improved the quality of radio communication. Characterizing Radio Channels builds a bridge between the history of science and the history of technology by inspecting an immaterial engineering entity--radio channels--whose control required significant scientific research. In the history of science...

This dissertation argues that Chile's history of computing is tightly interwoven with the history of the Chilean state. It begins by documenting the government use of mechanical tabulating machines during the 1920s and 1930s and concludes with the disbanding of the state computer enterprise known as ECOM in 1991. The dissertation pays particular attention to the period between 1964 and 1973, which was marked by the presidencies of Christian Democrat Eduardo Frei Montalva and Socialist Salvador Allende Gossens. The dissertation addresses three central questions. First, it asks how Chilean economic policies and political events shaped the country's technological history. Second, it asks what we can learn from computers if we treat them as texts for understanding historical processes in Chile, the Latin American region, and the developing world. Finally, it addresses how Chile's political leaders used computing machines in their attempts to control Chile's social, economic, and political development and to forward their plans to modernize the Chilean nation. It argues that computers proved valuable not only in producing the Chile of today but in articulating national goals that changed over time.; (cont.) Government, use of computers both reflected and made possible the ideological programs of developmentalism...

This dissertation focuses on the pursuits of a particular subset of automobile users: hot rodders, those who modify their standard production automobiles for improved performance. More specifically, this project examines the history of the speed equipment industry - the aftermarket subsector which manufactures high-performance products for hot rodders - from its infancy in the 1910s through the mid 1980s. The thesis begins by examining the role of technological enthusiasm in the early growth of hot rodding, focusing in particular on the ways in which this enthusiasm led a handful of individuals to begin to manufacture high-performance parts in the 1910s, 1920s, and 1930s. After tracing the wartime experiences of these industry pioneers, the project then explores the ways in which, in the midst of America's postwar affluence, the spectacular growth both of the high-performance industry and of hot rodding itself helped spawn the youth-oriented musclecar movement upon which the Big Three would later feed. In its examination of the 1940s and 1950s, the dissertation closely examines the evolution of this industry's production methods in an attempt to understand the manufacturing dynamics of a market-sensitive, flexibly-oriented, late-twentieth-century industrial sector.; (cont.) The thesis then explores the ways in which this industry dealt with automotive safety and environmental legislation in the 1960s and 1970s. It concludes with a discussion of the fragmentation of the hot rod market during the 1970s and 1980s...

With the emergence of biomedical technologies, human body parts from living or dead donors have become commodities in the international networks of trade. This dissertation tries to understand religious, political and ethical discourses on this emerging economy and how it creates its subjects in Turkey. By drawing analogies from the early days of anatomy and mental health practices and by using a three-fold-corpus (state, body and law) as a framework, it illustrates how the state, the religious law on the body, and social inequalities turn some subjects to objects of this biomedical practice while extending life for others. Life histories, oral histories, doctors' and patients' accounts, media reporting, urban legends, cinematography, theater, poetry and literature speak of this new biomedical life. The meaning of the cadaver, the brain-dead body, and the living donor are reevaluated. The personhood of suicides, the homeless, the poor, the mentally ill, the immigrant, and women are all questioned with the redefinition of boundaries of life and death. Biomedicine effects this kind of social change.; (cont.) A cultural history of this production sheds a light onto how Turkey has become one of the centers of organ trafficking in the Middle East in the 1990s...

This is a study of Japan and Taiwan's different responses to the expansion of the global drug industry. The thesis focuses on the problematic of "voicing," of how a state can make its interests heard in the International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH). The ICH is a unique project that facilitates the formation of a single global market by creating universal standards for clinical trials and drug approvals. Tracing, through "slow motion" ethnography, step by step, why Japan claims a racial difference requires additional local clinical trials with "Asian bodies," this thesis rejects conventional interpretations of protectionism for Japan's resistance to globalization. It argues that more than protectionism is involved, and that a rich ethnographic understanding of Japan's medical infrastructure is required to understand the claim of biological, cultural, and national differences, as well as biostatistical arguments about the ambiguities of "extrapolation" of clinical data from one place to another.; (cont.) The inherent ambiguities of efforts to create "bridging" studies as a temporary solution to these problematics created a deadlock in the ICH, and provided an opening for Taiwan...

In this thesis, I examine the current reorganization of office or information work in its technological, spatial, social and cultural aspects. Based on ethnographic and historical methods, I explore how information and communication technologies, and spatial designs combined with specific organizational visions shape the social organization and culture of work. Analyzing ideas as well as material configurations, design as well as use, and developments in offices as well as those beyond the office, I am particularly concerned with the new forms of life and cultural formations these developments produce. The 1990s saw a development towards more flexible, mobile and virtual ways of officing, such as non-territorial offices and remote work. Analyzing the alternative officing movement in the context of wider economic and cultural changes, I demonstrate the strategic role technology plays for the movement's vision of a less place-based definition of work. Suggesting an alternative intellectual origin for today's office concepts different from Taylorism, I opt for the concept of office landscaping, an influential German office concept developed after WW2 and inspired by cybernetics. Fieldwork in a present day innovative office design firm reveals a deep tension in its office designs between a more flexible and mobile organizational goal...

Reproduction is a site for understanding the ways in which people reconceptualize and re-organize the world in which they live. This dissertation tries to understand the world of birth under the regime of closures and fragmentation that governs the lives of Palestinians. It describes how checkpoints, closures, curfews have come to characterize childbirth in Palestine. It illustrates how the changing infrastructure, economy and discourse around birth produce new experiences of life in the medical sphere and in a family. Oral histories, life histories, doctors', midwives' and mothers' accounts, news reports and literature speak of these new conditions and experiences of birth and life. The meanings and structures of medicine, family and motherhood are thus remade. Oral histories focus on a history of the health infrastructure and movements in medicine, in particular the sumud (steadfastness) movement and the popular health movement. They illustrate how the figure of the doctor overlaps with that of the political leader. They identify the new health infrastructures built to assist birth during the closure which have different politics than the earlier movements, marking the post-socialist age, but show remarkable continuities with them in their emergence...

Fighting Engineers examines social conflict as the cause of the formation of professional mechanical engineering in the nineteenth century U.S. Navy. In the middle of that century, the Navy began to utilize steam engines for motive power. Navy administrators recognized the need for engineering officers to design and operate ships' steam power plants, but the social and political status of staff engineering officers was unclear. Their rank was relative to line officers, the men who navigated the ship and commanded the crew. Engineers possessed no legal command authority. This created problems as engineers' responsibilities increased during the Civil War. In response to shortcomings evident in the training of the engineer corps during the Civil War, the U.S. Naval Academy in the postwar period designed an unprecedented technical curriculum. Through this program, the Navy trained the nation's first group of modern mechanical engineers. As Navy engineers built their profession after the war, they attempted to redefine what it meant to be a naval officer. The officer ideal moved from the aristocratic warrior of the antebellum period to a college educated, scientifically minded professional late in the century. To maximize the political utility of their technical expertise...

My research is about the particular effects of Vietnam's economic liberalization program (known as "doi moi") on the local food and market system in Hanoi. Doi moi policies, which began in the late 1980s, have instituted major changes in both the national system of agricultural production and in Hanoi's local system of marketplaces. The doi moi reforms have created many new opportunities in Hanoi, but they have also re-configured social relationships and market spaces along the food chain to present new kinds of risk for consumers. These include harmful chemicals, goods of uncertain quality, and sellers who operate outside of the moral obligations of the dominant system of personal relationships. These things have not yet been resolved through regulation and have therefore been left to consumers and sellers to work out among themselves. The competition between various actors to manage foodborne risk in the absence of state regulation has taken place amidst the state's campaign to re-order Hanoi's market system according to neoiberal ideals.; (cont.) This has made the local market system a site for the enactment of a symbolic politics of modernity in which discourses that are really about risk and political economy have been obscured by their expression as a debate about "tradition" and modernity." Beneath the discourse of modernization lies a range of hybrid market worlds as well as systemic issues related to the transition from a centrally planned economy to a free market system.; by Margaret A. Hiesinger; Thesis (Ph. D. in History...

This thesis traces the development of American bacteriology during the first quarter of the twentieth century. While bacteriology experienced a period of rapid growth, an enduring disciplinary anxiety equally characterized the field. In particular, bacteriologists feared increasing specialization and conceptual fragmentation. Leading practitioners repeatedly worried that their science constituted a collection of unrelated techniques, carried out in the service to other practical endeavors without the benefit of an underlying theory or unifying language. I suggest that the sources of bacteriology's rapid professional growth equally accounted for this sense of conceptual impoverishment and disciplinary privation. Typically, bacteriologists focused on what bacteria did rather than what they were in any biological sense. The first three chapters provide a comprehensive survey of the institutional contexts bacteriology (e.g., medical schools, public health laboratories, water sanitation works, dairies, land-grant colleges, and agricultural experiment stations). For the most part, bacteriologists studied bacteria only so far as to isolate, identify and eliminate pathogens. Dairy and soil bacteriologists, however, sought to distinguish productive types of bacteria...

This dissertation asks how the United States physically built its global empire. Between 1840 and 1930, empire building involved the establishment of a network of naval bases and coaling stations. By focusing on energy, I reconceptualize the American overseas empire as neither inevitable nor geographically predetermined. I trace how coal shaped U.S. expansion, how this expansion influenced ideas about national security, and how these security concerns affected the global environment. Coal reveals continuities in American foreign relations that link overseas expansion to responses to the introduction of steam power into ocean travel. As the Navy sought coal, it progressively assembled the familiar contours of America's global reach. The dissertation addresses both global and local history. It shows how policy makers before the Civil War demonstrated tremendous creativity in initiating geological investigations, diplomatic arrangements, and commercial agreements in foreign territories. Between the Civil War and 1898, these approaches gradually gave way to a more singular effort by the Navy to control strategic ports around the world. Soon, coal was so central to the Navy that coaling strategy and technology formed a foundation for the education of elite officers at the Naval War College...
