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
Tempe experienced rapid growth in population and area from 1949 to 1975, stretching its resources thin and changing the character of the city. City boosters encouraged growth through the 1950s to safeguard Tempe’s borders against its larger neighbor, Phoenix. New residents moved to Tempe as it grew, expecting suburban amenities that the former agricultural supply town struggled to pay for and provide. After initially balking at taking responsibility for development of a park system, Tempe established a Parks and Recreation Department in 1958 and used parks as a main component in an evolving strategy for responding to rapid suburban growth. Through the 1960s and 1970s, Tempe pursued an ambitious goal of siting one park in each square mile of the city, planning for neighborhood parks to be paired with elementary schools and placed at the center of each Tempe neighborhood. The highly-publicized plan created a framework, based on the familiarity of public park spaces, that helped both long-time residents and recent transplants understand the new city form and participate in a changing community identity. As growth accelerated and subdivisions surged southward into the productive agricultural area that had driven Tempe’s economy for decades, the School-Park Policy faltered as a planning and community-building tool. Residents and city leaders struggled to reconcile the loss of agricultural land with the carefully maintained cultural narrative that connected Tempe to its frontier past, ultimately broadening the role of parks to address the needs of a changing city.

In the fifteen years between the discovery of fetal alcohol syndrome (FAS) in 1973 and the passage of alcohol beverage warning labels in 1988, FAS transformed from a medical diagnosis between practitioner and pregnant women to a broader societal risk imbued with political and cultural meaning. I examine how scientific, social, moral, and political narratives dynamically interacted to construct the risk of drinking during pregnancy and the public health response of health warning labels on alcohol. To situate such phenomena I first observe the closest regulatory precedents, the public health responses to thalidomide and cigarettes, which established a federal response to fetal risk. I then examine the history of how the US defined and responded to the social problem of alcoholism, paying particular attention to the role of women in that process. Those chapters inform my discussion of how the US reengaged with alcohol control at the federal level in the last quarter of the twentieth century. In the 1970s, FAS allowed federal agencies to carve out disciplinary authority, but robust public health measures were tempered by uncertainty surrounding issues of bureaucratic authority over labeling, and the mechanism and extent of alcohol’s impact on development. A socially conservative presidency, dramatic budgetary cuts, and increased industry funding reshaped the public health approach to alcoholism in the 1980s. The passage of labeling in 1988 required several conditions: a groundswell of other labeling initiatives that normalized the practice; the classification of other high profile, socially unacceptable alcohol-related behaviors such as drunk driving and youth drinking; and the creation of a dual public health population that faced increased medical, social, and political scrutiny, the pregnant woman and her developing fetus.

"Wide adaptation" is an agricultural concept often employed and seldom closely examined. Norman E. Borlaug, while working for the Rockefeller Foundation (RF) on an agricultural project in Mexico in the 1950s, discovered that some tropical wheat varieties could be grown over broad geographic regions, not just in Central and South America but also in the Middle East and South Asia. He called this wide, or broad, adaptation, which scientists generally define as a plant type that has high yields throughout diverse environments. Borlaug soon made wide adaptation as a core pillar of his international wheat program. Borlaug's wheat program rapidly expanded in the 1960s, and he and his colleagues from the RF heavily promoted wide adaptation and the increased use of fertilizers in the Middle East and India. These events led to the green revolution, when several countries rapidly increased their wheat production. Indian wheat cultivation changed radically in the 1960s due to new technologies and policy reforms introduced during the green revolution, and farmers' adoption of 'technology packages' of modern seeds, fertilizer, and irrigation.
Just prior to the green revolution, Indian wheat scientists adopted Borlaug’s new plant breeding philosophy—that varieties should have as wide an adaptation as possible. But Borlaug and Indian wheat scientists also argued that wide adaptation could be achieved by selecting only plants that did well in high fertility and irrigated environments. Scientists claimed, in many cases erroneously, that widely adapted varieties still produced high yields in marginal, or resource poor, areas. Many people have criticized the green revolution for its unequal spread of benefits, but none of these critiques address wide adaptation—the core tenant held by Indian wheat scientists to justify their focus on highly productive land while ignoring marginal and rainfed agriculture. My dissertation describes Borlaug and the RF's research program in wide adaptation, Borlaug's involvement in the Indian wheat program, and internal debates about wide adaptation and selection under favorable environments among Indian scientists. It argues that scientists leveraged the concept of wide adaptation to justify a particular regime of research focused on high production agriculture, and that the footprints of this regime are still present in Indian agriculture.
