This chapter discusses how the final aphorism, 575, of Nietszsche's Dawn, presents a positive vision of humanity as future‐oriented and self‐cultivating. It explores how Nietzsche's vision of humanity as future‐oriented and self‐creating is taken up once again by him in his later writings. In the final aphorism Nietzsche's use of the symbolism of flight is significant. This final aphorism is entitled "We aeronauts of the spirit". As Duncan Large has pointed out, the aeronauts in the aphorism are flying an "air‐ship", (...) and their flying out over the sea indicates "how close is their kinship to their more earthbound, or at least sea‐bound mariner‐cousins". In addition to his use of the sea as a metaphor for both the infinity of the future and humanity's orientation toward this future, Nietzsche draws upon the metaphor of flight to elaborate on this continuation of human development.

Although the advantages of flight at high altitude were early recognized, so also were the physiological problems standing in the way of its realization. The idea of surmounting such problems by means of a pressurized cabin was advocated as early as 1909, while the first attempt to translate the concept into actuality occurred in 1921. Neither it nor several successive attempts enjoyed any real success until a project launched by the U. S. Air Corps in 1935 produced a breakthrough aircraft (...) designated the XC-35. The major reason for the favorable termination of that venture was the thoroughness of the engineering involved. But it is equally notable that this was the first instance in the age of powered flight where there was an active collaboration between the scientists and engineers, a rather curious circumstance in view of the fact that the achievement of altitude record-setting balloon flights in the nineteenth century had owed a great deal to an interconnection of aeronauts and scientists' laboratories. This paper focuses on the physiological investigations which informed the XC-35 engineers while at the same time bringing into being a new aeromedical laboratory taking the first small step toward turning aeromedicine into space medicine.

: Before he studied philosophy under Bertrand Russell, Ludwig Wittgenstein was trained as an engineer at the Technische Hochschule in Berlin. He then worked as a graduate research engineer at the University of Manchester, where he designed a variable volume combustion chamber and received a patent for an innovative propeller design in 1911. I argue that the methodology of contemporary aeronautical engineering research, involving the systematic use of experiments and scale models, affected the Bild theory of language in the Tractatus (...) Logico-Philosophicus. The principle of similitude, underlying the mathematical resolution of scale effect problems associated with wind tunnel research on models, is reflected in the law of projection in the Tractatus.

This is a comprehensive biography of Ludwig Prandtl (1875-1953), the father of modern aerodynamics. His name is associated most famously with the boundary layer concept, but also with several other topics in 20th century fluid mechanics, particularly turbulence (Prandtl's mixing length). Among his disciples are pioneers of modern fluid mechanics such as Heinrich Blasius, Theodore von Kármán and Walter Tollmien. Furthermore, Prandtl founded the Aerodynamische Versuchsanstalt (AVA) and the Kaiser-Wilhelm-Institut für Strömungsforschung in Göttingen, both of them seeds for the growth (...) of fluid mechanics in Germany. Yet Prandtl was also a representative of aeronautical research - from Imperial Germany via the Weimar Republic to the "Third Reich". Although not a party member, he assumed the role of a goodwill ambassador for Nazi Germany. This objective treatment of his career will be of interest to all scientists and historians wanting to learn more about Prandtl's influence and the early development of fluid- and aerodynamics.

We argue that providing cumulative risk as an estimate of the uncertainty in dynamically changing risky environments can help decision-makers meet mission-critical goals. Specifically, we constructed a simplified aviation-like weather decision-making task incorporating Next-Generation Radar images of convective weather. NEXRAD radar images provide information about geographically referenced precipitation. NEXRAD radar images are used by both pilots and laypeople to support decision-making about the level of risk posed by future weather-hazard movements. Using NEXRAD, people and professionals have to infer the uncertainty (...) in the meteorological information to understand current hazards and extrapolate future conditions. Recent advancements in meteorology modeling afford the possibility of providing uncertainty information concerning hazardous weather for the current flight. Although there are systematic biases that plague people’s use of uncertainty information, there is evidence that presenting forecast uncertainty can improve weather-related decision-making. The current study augments NEXRAD by providing flight-path risk, referred to as the Risk Situational Awareness Tool. RSAT provides the probability that a route will come within 20 NMI radius of hazardous weather within the next 45 min of flight. The study evaluates four NEXRAD displays integrated with RSAT, providing varying levels of support. The “no” support condition has no RSAT. The “baseline” support condition employs an RSAT whose accuracy is consistent with current capability in meteorological modeling. The “moderate” support condition applies an RSAT whose accuracy is likely at the top of what is achievable in meteorology in the near future. The “high” support condition provides a level of support that is likely unachievable in an aviation weather decision-making context without considerable technological innovation. The results indicate that the operators relied on the RSAT and improved their performance as a consequence. We discuss the implications of the findings for the safe introduction of probabilistic tools in future general aviation cockpits and other dynamic decision-making contexts. Moreover, we discuss how the results contribute to research in the fields of dynamic risk and uncertainty, risk situation awareness, cumulative risk, and risk communication. (shrink)

Although much recent social science and humanities work has been a revolt against simplification, this volume explores the contrast between simplicity and complexity to reveal that this dichotomy, itself, is too simplistic. John Law and Annemarie Mol have gathered a distinguished panel of contributors to offer—particularly within the field of science studies—approaches to a theory of complexity, and at the same time a theoretical introduction to the topic. Indeed, they examine not only ways of relating to complexity but complexity _in (...) practice._ Individual essays study complexity from a variety of perspectives, addressing market behavior, medical interventions, aeronautical design, the governing of supranational states, ecology, roadbuilding, meteorology, the science of complexity itself, and the psychology of childhood trauma. Other topics include complex wholes in the sciences, moral complexity in seemingly amoral endeavors, and issues relating to the protection of African elephants. With a focus on such concepts as multiplicity, partial connections, and ebbs and flows, the collection includes narratives from Kenya, Great Britain, Papua New Guinea, the Netherlands, France, and the meetings of the European Commission, written by anthropologists, economists, philosophers, psychologists, sociologists, and scholars of science, technology, and society. _Contributors._ Andrew Barry, Steven D.

The first of its kind, this book is an in-depth history of hydrodynamics from its eighteenth-century foundations to its first major successes in twentieth-century hydraulics and aeronautics. It documents the foundational role of fluid mechanics in developing a new mathematical physics. It gives full and clear accounts of the conceptual breakthroughs of physicists and engineers who tried to meet challenges in the practical worlds of hydraulics, navigation, blood circulation, meteorology, and aeronautics, and it shows how hydrodynamics at last (...) began to fulfill its early promise to unify the different worlds of flow. Richly illustrated, technically thorough, and sensitive to cross-cultural effects, this history should attract a broad range of historians, scientists, engineers, and philosophers and be a standard reference for anyone interested in fluid mechanics.

This essay investigates technical aspects of the history of aviation in the Republic of China, focusing on the period between 1920 and 1937. It suggests that Chinese authors and administrators came to see the establishment of technical infrastructure as dependent on the education of personnel who could assume responsibility for maintaining and expanding Chinese aviation ventures, rather than on specific technologies or practices. Magazines and journals in the 1920s reflected concerns with the establishment of weather observation and reporting, radio communications, (...) and technical education in service of aviation; the last of these was critical for the first two. Provisions for technical work and training were reflected in contracts that were drawn up in the years around 1930 to establish three aviation projects in the Republic: the China National Aviation Corporation (CNAC), the Eurasia Aviation Corporation, and Southwest Airlines. Subsequent contracts and reports for CNAC and Eurasia in the years before the 1937 outbreak of war with Japan suggested a particular emphasis on the technical education of personnel as an important step in building Chinese aviation infrastructures.

Bertrand Russell's work on the foundations of mathematics apparently played a decisive role in persuading Wittgenstein to abandon his aeronautical engineering studies in favor of philosophy. Wittgenstein's influence on Russell turned out to be profound as well: two years after they first met, Wittgenstein had delivered an objection to Russell's theory of judgment that was so devastating that it led to the abandonment of a major philosophical project of Russell's, leaving him reportedly “paralysed”. Two fundamental elements are pivotal to the (...) logicism of Russell's Principles of Mathematics: his conception of a proposition, and his commitment to the doctrine of the unrestricted variable. In addition to the ontological problems facing his theory of propositions, Russell also became convinced that his ontology of propositions contained fundamental logical problems, as he encountered recurring contradictions in his attempts to formalize a propositional logic that would comport with his philosophical theory.

Background Many studies have investigated the adherence to professional codes of ethics by nurses. However, no study has explicitly examined the relationship between workload and adherence to professional codes of ethics among Iranian nurses. Objective This study aimed to explore the relationships between workload and adherence to professional codes of ethics among a sample of Iranian nurses. Materials and Methods A cross-sectional descriptive study was conducted on 213 nurses who were randomly selected from the different wards of Shahid Beheshti Hospital (...) of Kashan, Iran. Data collection instruments included a personal characteristics questionnaire, the Nursing Ethics Questionnaire, and the National Aeronautics and Space Administration Task Load Index. The Chi-square, the Spearman correlation coefficient, the Kruskal–Wallis, and Mann–Whitney U tests were used to analyze the data. Results A majority of nurses were females, married, and permanently employed. The mean of the overall perceived workload and adherence to professional codes of ethics were 76.36 ± 13.64 and 13.98 ± 2.58, that were at high and moderated level, respectively. Spearman correlation test showed no significant correlation between perceived workload and adherence to professional codes of ethics. A significant difference was found between the mean scores of adherence to professional codes of ethics in nurses working in different departments. Conclusion Participating nurses perceived high levels of workload but their mean adherence to professional codes of ethics was at a moderate level. The perceived workload was indirectly correlated with adherence to professional codes of ethics. (shrink)

This study pragmatically makes a descriptive analysis of metadiscourse in academic lectures from the perspective of the relevance-adaptation theory. Based on the relevance theory and the adaptation theory, the relevance-adaptation model is constructed to explore the occurrence, the pragmatic description and the role of metadiscourse in academic lectures. The data is collected from George Lakoff’s 10 academic lectures on cognitive linguistics at Beijing University of Aeronautics and Astronautics in 2004 and some academic lectures audio-taped in classrooms. The results of (...) the study show that 1) the occurrence of metadiscourse in academic lectures is pervasive; 2) the process of choosing appropriate metadiscourse is dynamic and the result of searching for relevance and making contextual adaptations – the process of searching for relevance of metadiscourse is measured in terms of three pairs of the distinctions, namely, contextual effect and processing effort, explicature and implicature, and conceptual meaning and procedural meaning, and contextual adaptations of metadiscourse are constrained by such factors as linguistic reality, psychological motivations and social conventions; 3) the role of metadiscourse in academic lectures is an active discourse constructor.

The longing for aerial flight has been one of mankind's most consuming preoccupations. A burning desire for lightness, verticality, and flight is opposed to the fatality of universal gravity. Jules Michelet, in his study of the subject, entitled L'Oiseau (The Bird), which he wrote toward the end of his life, deems this aspiration for upward motion to be characteristic of all nature. He writes: “It is the cry of all the earth, of the world and of all life… : ‘Wings! (...) We want wings, we want flight and movement.’” From ancient times, this basic element of physical experience has nourished human imagination and been a source of motivation for the pursuit of scientific knowledge. Mesopotamian civilization had its winged divinities and spirits; indeed the Western tradition of depicting winged persons has been linked to the influence of Mesopotamian art. As Jules Duhem has pointed out, four centuries before Jesus Christ, Aristotle himself was already exploring certain notions that have become part of the history of ideas of aeronautics and astronomy. Among these are the ideas of void, weight, the resistance of air, and the movement of birds and other flying creatures. Duhem has also demonstrated that Aristotle proposed an explanation, as imperfect as it was, for what causes projectiles to fall from the sky. Throughout the ages, humanity has continually expressed its desire to fly: “Man is proud of being free and of leaning on nothing,” Elias Canetti has written in regard to man's upright position. Striking examples of the impulse to fly are to be found not only in scientific discourse but in myths, literature, and works of art. (shrink)

In 1960, the US government and British protectorate of Zanzibar signed an agreement that allowed US contractors working for the National Aeronautics and Space Administration (NASA) to build an earth station that would support Project Mercury, the first manned US satellite mission. This article focuses on the development of the Project Mercury earth station in Zanzibar during 1959-1964. To historicize the earth station’s establishment, the focus lies on the geopolitical and sociotechnical relations that resulted in the Zanzibar station.

ArgumentThis paper analyzes the concept ofmilitarizationin both senses of the word, that of mobilization for war and that of social control exercised by military forces. During the Spanish Civil War (1936–1939), the role and nature of meteorology was transformed by the rebel band on the basis of the mythification of a Service model that was supported by victory and that would be projected as a paradigm for the postwar years. The newServicio Meteorológico Nacionalreflected the social control exerted by the Franco (...) regime and its aeronautical and military interests. The “amphibianism” – or quality of being both civil and military simultaneously – is one of the main features of this transformation. Interestingly, this dual (civil and military) condition of meteorologist appears to be intrinsic to the construction of a new “sphere of practices and knowledge” in Francoist Spain. (shrink)

Abstract.Since the earliest ages of humanity, the contemplation of the starry sky has invited the human being to ask: “Who am I? Where is my origin? What is my destiny?” The revolution introduced by modem astronomy has affected how humankind understands itself, and the development of aeronautical and then astronautical techniques introduced a new experiment for humanity—that of being citizen of the sky. By carrying out the dream of Icarus, has humanity realized the attempt of Prometheus? Would we take the (...) place of the gods or God? Do religions have to fear the conquest of space? Despite modern science and the knowledge we have accumulated, space still holds its share of mystery, nurtured by its vast dimensions and startling beauty. Space continues to raise the issue of meaning. (shrink)

The Space Act of 1958 begins, “The Congress hereby declares that it is the policy of the United States that activities in space should be devoted to peaceful purposes for the benefit of all mankind.” In March 1982, a Defense Department official commented on the statute: “We interpret the right to use space for peaceful purposes to include military uses of space to promote peace in the world.”1 The absurdity of this willful misinterpretation amazed me on first reading, and months (...) later it readily came to mind when I was looking for an effective way to illustrate the politics of interpretation. With just the right touch of moral indignation, I offered my literary criticism class this example of militaristic ideology blatantly misreading an antimilitaristic text.“But … the Defense Department is right!” objected the first student to speak. Somewhat amused, I spent the next ten minutes trying, with decreasing amusement, to show this student that the Reagan administration’s reading was clearly, obviously, painfully wrong. I pointed to the text. I cited the traditional interpretation. I noted the class consensus, which supported me. All to no avail. It was at this point that I felt that “theoretical urge”: the overwhelming desire for a hermeneutic account to which I could appeal to prove my student wrong. What I wanted was a general theory of interpretation that could supply rules outlawing my student’s misreading.This little hermeneutic fable introduces the three topics of my essay. One topic is the theoretical moment that concludes the narrative; another is the simple plot, a brief rhetorical exchange; and finally there’s the institutional setting in which the exchange takes place. These three topics preoccupy the sections that follow. Section 1 analyzes the problems resulting from the theoretical urge, the impasse of contemporary critical theory. Section 2 proposes my solution to this impasse, a solution I call rhetorical hermeneutics, which leads in section 3 to a rhetorical version of institutional history. 1. “National Aeronautics and Space Act of 1958,” United States Statutes at Large , vol. 72, pt. 1, sec. 102, p. 426; Robert Cooper, director of the Defense Advanced Research Projects Agency, quoted in Frank Greve, “Pentagon Research Retains Vision of ‘Winning’ N-war,” Miami Herald, 27 Mar. 1983, sec.

The relative input of payoffs and probabilities into risk judgment The study was designed to investigate the relative input of payoffs and probabilities into risk judgment on the basis of the analysis of information search pattern. The modified version of MouselabWeb software was used as an investigative tool. The amount, the kind and the order of information accessed by subjects to evaluate risk was collected from ordinary respondents and respondents trained in mathematics and statistics. In the latter group were 75 (...) students and young researchers working at National Aeronautics and Space Administration. The ordinary subjects were 67 Polish students of social sciences. As expected, the NASA group considered more information than ordinary students and searched for more information about probabilities. However, the ratio of information about payoffs to probabilities was close to 1 in both groups. Moreover, average risk rates were similar in both groups. It was also observed that risk rates were positively related with the amount of information about probabilities considered by subjects. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Fallout from Government-Sponsored Radiation ResearchCarol Mason Spicer (bio)On December 28, 1993, Energy Secretary Hazel R. O'Leary publicly appealed to both the executive and legislative branches of the United States Government to consider compensation for individuals who were harmed by their exposure to ionizing radiation while enrolled in government-sponsored studies conducted between 1940 and the early 1970s.1 The call for compensation was issued three weeks after Secretary O'Leary disclosed that (...) radiation experiments involving humans, sometimes without their consent, had occurred under the auspices of the Atomic Energy Commission (AEC), a forerunner of the Department of Energy (DOE). Secretary O'Leary directed her department to investigate the nature and extent of the experiments, report on their medical and ethical acceptability, and locate the research subjects or their families.Background to the Federal Advisory CommitteeDespite the fact that the existence of many government-sponsored radiation experiments was not a secret—much of the research was reported at the time in scientific journals, and in 1986, Representative Edward J. Markey (D-MA) conducted congressional hearings on such radiation research—Secretary O'Leary's disclosure of the AEC experiments and her call for compensation made the experiments common knowledge and sparked a swift and complex governmental response involving both the executive and legislative branches.It is curious that the "radiation experiments" have garnered so much attention now, since they were virtually ignored in the wake of the 1986 hearings. Secretary O'Leary's disclosure of the radiation studies grew out of a general reassessment of secrecy in government. In April 1993, the Clinton administration set out to review the system of government secrecy that evolved during the Cold War, and in May 1993, DOE began reviewing and declassifying files pertaining to nuclear weapons research. When Dan Reicher, a top aide to Secretary O'Leary, informed her in November of the impending publication of an Albuquerque Tribune investigative report (Welsome 1993) on an experiment conducted between 1945 and 1947 in which 18 subjects were injected with plutonium, [End Page 147] the topic of questionable research involving the exposure of human subjects to radiation was added to the DOE list of information to be disclosed. At the time, it was thought to be but one small part of a massive quantity of DOE information to be made public.As part of its effort to investigate the radiation experiments, DOE established a toll-free telephone hot line for individuals who thought they might have been the subjects of radiation exposure experiments. The hot line, originally staffed by three people to handle the anticipated few dozen calls per day, received more than 2,000 calls in the first week. By early January the hot line was flooded with 6,000 to 10,000 calls daily, and its staff had increased more than ten-fold. Although many of the calls were deemed not to be candidates for further investigation, the extent of the radiation-related experiments, sponsored not only by AEC, but also by the military and other government departments and agencies, took officials by surprise.On December 30, the Department of Defense, the Department of Veterans Affairs, and the National Aeronautics and Space Administration all announced that they were initiating thorough reviews of their files to determine the extent and nature of any radiation experiments conducted under their auspices.2 In January, the CIA and the Department of Health and Human Services, including the National Institutes of Health, followed suit.The White House publicly entered the arena in late December announcing that it would hold a meeting on January 3, 1994, to help coordinate the government's investigative effort. At the same time, Senator Edward M. Kennedy (D-MA) called for a mid-January congressional hearing to investigate experiments conducted between 1946 and 1956 in which mentally retarded boys at the Fernald State School in Massachusetts were fed radioactive iron supplements or milk containing radioactive calcium to enable researchers to trace the absorption of those nutrients. Senator Kennedy's hearing, conducted by the Subcommittee on Health of the Senate Committee on Labor and Human Resources, was the first of a number of congressional hearings held earlier this year to investigate the...

In lieu of an abstract, here is a brief excerpt of the content:Maps for the Classical World: Where Do We Go from Here?Richard TalbertThe apa’s classical atlas project was conceived as the means to an end, and rightly so. Good maps were taken to be vital tools for understanding ancient history and culture at any level, and the ones available in the early 1980s were altogether woefully inadequate. The project was designed to fill this void by preparing a comprehensive atlas (...) for publication in the not-too-distant future.To make a definitive claim at this moment that the target of publication by the end of 1999 will be met must still rank as hubris. Without doubt, however, the odds have increasingly shifted over the past few years in favor of timely completion. As everyone knows, the problems of designing, funding, and developing any ambitious collaborative project are immense, and the atlas has been handed its full share of such difficulties and more. Yet gradually the difficulties seem to have been surmounted, and the project—at present, anyway—remains resolutely on schedule, as much to the surprise of its Director as to everyone else.As the odds have shifted, so, too, has my own perception of the project as an end. To be sure, the maps appearing in the atlas volume will offer the intended comprehensive vision of the physical and cultural landscape of classical antiquity that has been so seriously lacking since Carl Müller provided the last one for William Smith’s Atlas of Ancient Geography in the 1870s. Further gains are assured, too. In particular, to accommodate different needs, it should certainly prove practical to issue the maps in a variety of alternative formats—in sets of loose sheets, for example (with or without cultural data marked on the ancient physical landscape), as wall-maps, slides, digitized images, even a reduced-size textbook atlas. One way or another, these maps have the potential to exert a formative influence on our perception of the classical landscape for many decades to come.Even at the current stage, well before publication, the Atlas Project [End Page 323] has already stimulated fresh attention to cartography: this has grown without any special effort on the project’s part. Most notably, colleagues have become aware that there is now for the first time somewhere to which they can turn as they seek out suitable cartographic materials and design for their research or publications or field survey.Classical studies worldwide would benefit immensely if that “somewhere” were to be made a permanent “center,” established around the same time as the publication of the Atlas of the Greek and Roman World. In the creation of the atlas, both materials and expertise have been accumulated, which it would be irresponsible simply to abandon. The materials cover a wide range—from elements for all the aeronautical charts forming the physical bases for the atlas maps, to copies of older rare maps devoted to classical antiquity.Such maps (and whatever text accompanies them) are by no means necessarily all about to be rendered obsolete by the atlas. The French “archaeological atlases” of Algeria and Tunisia, for example, were compiled by the Brigades Topographiques in the late nineteenth and early twentieth centuries at scales as generous as 1 : 50,000, whereas the atlas limits itself to 1 : 500,000 in this region (and the area covered by one map at 1 : 500,000 corresponds to literally dozens at 1 : 50,000). Thus for any study with a close focus on Algeria or Tunisia, these French series remain indispensable, although the Tunisian one, with its two editions, is exceptionally rare and hard to obtain. Typically, the few libraries that hold this material have bound the original loose sheet maps into books (rendering it impossible to use the sheets individually), and for obvious reasons, they are not willing lenders. The Atlas Project, I imagine, has been the first to photograph the printed map sheets onto transparent plastic positives. These are sturdy, dimensionally stable, and immune from the fading and deterioration of paper; in addition, when they are laid on top of other maps, everything underneath remains visible.Examples of further cartographic materials for the classical world which will continue to...

Abraham Robinson is well-known as the inventor of nonstandard analysis, which uses nonstandard models to give the notions of infinitesimal and infinitely large magnitudes a precise interpretation. Less discussed, although subtle and original–if ultimately flawed–is Robinson's work in the philosophy of mathematics. The foundational position he inherited from David Hilbert undermines not only the use of nonstandard analysis, but also Robinson's considerable corpus of pre-logic contributions to the field in such diverse areas as differential equations and aeronautics. This tension (...) emerges from Robinson's disbelief in the existence of infinite totalities (any mention of them is ‘literally meaningless’) and the fact that much of his work involves them. I argue that he treats infinitary avenues of mathematics as useful tools to avoid this difficulty, but that this is not successful to the extent that these tools must be justified by a conservative extension from finitary mathematics. While Robinson provides a compelling and unorthodox pragmatic justification for the role of formal systems in mathematical practice despite their apparent infinitary presuppositions, he deflates mainstream mathematics to a collection of games that occasionally produces meaningful results. This amounts to giving up on a commitment to reconciling his finitism with his mathematical practice. (shrink)

ArgumentDuring the interwar period research on turbulence met with interest from different areas: in aeronautical engineering turbulence became a subject of experimental study in wind tunnels; in naval architecture and hydraulic engineering turbulence research was on the agenda because of its role for skin friction; applied mathematicians and theoretical physicists struggled with the problem to determine the onset of turbulence from the fundamental hydrodynamic equations; experimental physicists developed techniques to measure the velocity fluctuations of turbulent flows. In this paper I (...) describe the rise of turbulence in the 1920s and 1930s as a research field under the label of applied mechanics. Although the focus is on Germany, the international development of this research field is illuminated by the role which Ludwig Prandtl played as its acknowledged “chief” (G. I. Taylor). I argue that the multifaceted character of this research field calls for an epistemology and historiography which intrinsically takes the interaction of science and engineering into account.

ArgumentThe history of ballooning has received considerable attention from historians examining the technological innovations behind it as well as from scholars interested in aeronautical anecdotes concerning launches and disasters. The cultural importance of this new machine, however, remains less fully analyzed. This essay explores one facet of that history through a discussion of the commodification of launches in France and Great Britain. These two countries, which have larger middling classes as well as a higher degree of commercialization in general, provided (...) a fertile environment for aeronauts seeking to instruct and entertain an audience willing to fund ballooning. Balloonists had to invent ways to market this scientific discovery and determine how best to attract paying customers. The audience was entertained while simultaneously empowered to act as witnesses to what balloonists presented as a scientific experiment. (shrink)

This article seeks rapprochement between the sociology of knowledge and philosophy of science by attempting to capture the best social constructionist insights within a strongly realistic philosophy of science.

On 16 September 1987, the main chlorofluorocarbon-producing and -consuming countries signed the Montreal Protocol, despite the absence of a scientific consensus on the mechanisms of ozone depletion over Antarctica. We argue in this article that the rapid diffusion from late 1985 onwards of satellite images showing the Antarctic ozone hole played a significant role in this diplomatic outcome. Whereas negotiators claimed that they chose to deliberately ignore the Antarctic ozone hole during the negotiations since no theory was able yet to (...) explain it, the images still loomed large for many of the actors involved. In Western countries, the National Aeronautics and Space Administration's (NASA) satellite visualizations were diffused through the general press and television stations. Other popular and mass media outlets followed quickly. In describing the circulation and appropriation processes of these images within and beyond the scientific and negotiation arenas, we show that the ozone hole images did play an important part in ozone diplomacy in the two years leading up to the signing of the Montreal Protocol, both in the expert and diplomatic arenas and as public diplomacy tools. We conclude by encouraging scholars to engage with new visual archives and to contribute to the development of the vibrant new field of research on visual diplomacy. (shrink)

He directed the Committee: (1) to uncover the history of human radiation experiments and intentional environmental releases of radiation; (2) to identify the ethical and scientific standards for evaluating these events; and (3) to make recommendations to ensure that whatever wrongdoing may have occurred in the past will not be repeated.The Committee was composed of 14 members: a citizen representative and 13 experts in bioethics, radiation oncology and biology, epidemiology and statistics, public health, history of science and medicine, nuclear medicine, and law. We reported to a cabinet-level group (the Human Radiation Interagency Working Group) convened by the president, which includes the secretaries of defense, energy, health and human services, and veterans affairs; the attorney general; the administrator of the National Aeronautics and Space Administration; the director of the Central Intelligence Agency; and the director of the Office of Management and Budget.On April 21, 1994, at the end of the first day of our first meeting, President Clinton invited us to the White House to personally communicate his commitment to the process we were about to undertake. He urged us to be fair, thorough, and unafraid to shine the light of truth on this hidden and poorly understood aspect of our nation’s past. Our most important task, he said, was to tell the full story to the American public. [End Page 215] At the same time, we were to examine the present, to determine how the conduct of human research today compares with that of the past, and to assess whether, in light of this inquiry, changes need to be made in the policies of the federal government. Eighteen months later, the Committee’s attempt to tell the story of the past and to report on our inquiry into the present was delivered to the president in a 900-page Final Report (ACHRE 1995) and several supplemental volumes.The Committee’s charge was enormous. We were asked to conduct a massive investigation into events that occurred as much as 50 years ago and that involved the highest reaches of the defense establishment and the medical community. This investigation necessitated an examination of the conduct and policies of six federal agencies and countless agents in the private sector, as well as the location and interpretation of hundreds of thousands of documents, many of which were buried in obscure locations or were still classified.In addition, the Committee was instructed to establish standards for judging, in moral terms, the events that it uncovered. This charge necessitated the confrontation of contentious debates in moral thought and theory about history, relativism, and the significance of context in moral judgment. But our purpose was not to engage in these debates in the abstract. Although the Committee was not expressly charged with considering issues relating to remedies, including financial compensation, we felt obliged to address the type of remedies that we believed the government, as an ethical matter, should provide to subjects of experiments where the circumstances warranted such a response. Thus our deliberations about relativism and moral judgment were tied to concrete recommendations for public policy and were conducted in a public context that included participants from numerous adversarial legal proceedings.In tandem with our reconstruction of the past, we undertook three projects to examine the current state of human radiation experiments. First, we studied how each federal agency that currently conducts or funds research involving human subjects regulates and oversees its research activity. Second, from among the very large number of federally-supported research projects involving human subjects, we randomly selected 125 projects for closer scrutiny. We reviewed all available relevant documentation for each project in order to assess how well it appeared to protect the rights and interests of the participating subjects. Third... (shrink)
