The history of holography, the technology of three‐dimensional imaging that grew rapidly during the 1960s, has been written primarily by its historical actors and, like many new inventions, its concepts and activities became surrounded by myths and myth‐making. The first historical account was disseminated by the central character of this paper, George W. Stroke, while a professor of Electrical Engineering at the University of Michigan. His claims embroiled several workers active in the field of holography and information processing during the 1960s, but transcended personality conflicts: they influenced the early historiography of holography and the awarding of the Nobel Prize for Physics to . An extended discussion of these episodes, based on archival research, publications analysis and interviews with participants, reveals the importance and extraordinary allure of intellectual priority for practicing scientists, and how its history and explanations are woven from multiple accounts and contemporary interpretations.  相似文献

论文从创造教育学视角就美籍华裔杰出科技人才成才机制进行了分析探讨,认为世界上有2000多个民族、五大文化圈和众多的亚文化圈,不同民族和文化圈的科技发展水平差异甚大,杰出科技人才在不同民族和文化圈中所占比例亦有重大差距。即使在同一文化圈中,不同民族的科技发展水平和杰出科技人才所占比例差距也不小,而同一民族在不同文化圈中也有不同表现。美籍华裔科技人才是直接或间接受东亚文化圈影响的杰出华人科技人才,他们的成才机制必然有科技人才成才的共性逻辑,但也与其种族和文化有些许相关。美籍华裔科技人才成才机制受社会文化和个体素质内外因素的相互影响,一流科学家群落是美籍华裔科技人才成才的适宜组织环境;文化基因匹配是科技人才成才的精神土壤;优秀天赋是科技人才成才的物质基础;创新素质是科技人才成才的内在动力。  相似文献

Despite repeated announcements of its death or uselessness, the ‘linear model’ of science–technology relations persists, the notion that fundamental scientific research precedes applied studies that in time generate technological advances. This article undertakes first to revisit investigations and critiques of the model, and to remind historians of technology that intriguing alternatives to it have been developed. Second, using the case study of Cold War military jet propulsion, it argues that innovative, complex technologies have been created without reliable understanding of scientific fundamentals. These were messy, non‐linear, and failure‐filled processes, to be sure, yet they may well prove to have been more the rule than the exception, once scholars pursue richly textured studies of technical practice in experimental development. Ultimately, project needs to overcome engineering obstacles in technological innovation may provide the platforms and the funding to support basic scientific research as well, reversing the linear model’s expected flows.  相似文献

The Obama administration's controversial use of drones in Afghanistan, Pakistan and Yemen has made the subject a hot topic of political and academic discourse. While most of this debate has focused so far on the legal, ethical and prudential use of large armed aerial vehicles, this article seeks to address the potential wider impact of this new technological innovation. The article argues that drones constitute a new and disruptive technology not just in the way that they have been used to enable a new form of counterterrorism. Instead, it argues that drones pose a new form of terrorist threat against the West which is at present under‐analysed, unarticulated and underestimated. Part of the reason for this underestimation is the failure to appreciate the scale and scope of drone use for commercial purposes which is about to unfold. Technological innovation now means that drones will be capable of many jobs currently performed by small planes and helicopters, but more cheaply and easily—in addition to many other new applications. The proliferation of this cheap and easily available technology will make its application for terrorist use easy to achieve and difficult to counter. The ability of drones to penetrate traditional defences and established conceptions of what constitutes a plausible threat is a challenge which so far has gone unheeded. This article seeks to challenge that complacency.  相似文献

The posthuman has been looming large on the human horizon lately. Yet there is no shared understanding of what a posthuman future could possibly mean, and the tension between a technological‐scientific prospect of posthumanity and the critical posthumanist scholarship of the humanities is growing palpable. Whereas the former harbors a novel sense of historicity signaled by the expectation of an evental change to bring about the technological posthuman as a previously nonexistent and other‐than‐human central subject, the latter theorizes a postanthropocentric subjectivity of beings still human. In doing so, it extends the already familiar emancipatory concerns of the human world over the nonhuman, with special attention paid to the ecological other. Despite the occasional claims of critical posthumanism to bring humanities and technological‐scientific approaches to a shared platform, the prospect of technological beings of unparalleled power and the ecotopia of species equality do not fit together very well. In this article I argue that, in their present shape, technological posthumanity and critical posthumanism represent hardly reconcilable social imaginaries and two cultures of the posthuman future. My intervention is a plea for developing a more profound and mutual understanding of both. Instead of advocating particular agendas that nevertheless claim validity for the entirety of planetary life and the entire scholarly enterprise of knowledge‐production, we could invest more in efforts to come to grips with both social imaginaries and venture jointly into the creation of the conceptual tools of a new knowledge economy of understanding the rapidly changing world and our own (post)human prospects.  相似文献

The Belle Époque, often thought to be a period defined by nationalism, also saw the remarkable global proliferation of transnational affinities – especially those centred on race. Across Europe and its settler territories, notions of pan‐racial affinity spread alongside imperial nationalism, in the context of technological advancement that permitted novel imaginative possibilities. Meanwhile, texts of political imagination in Africa and Asia during this period – particularly those of pan‐Africanism and pan‐Islamism – demonstrate not only an awareness of the significance of racial thinking for Europe but a theorisation of the connections between Europe's racial imagination and its policies in the colonised world. The same advances in the fields of communication and travel that opened the door for new imaginative possibilities in Europe also enabled disparate communities in the colonised world to conceive of themselves, often for the first time, as collectively racialised subjects of a European world order.  相似文献

Abstract

Most accounts of the microelectronics revolution have emphasized the role of military patronage and procurement in the shaping of silicon technology and the consolidation of the semiconductor industry. Little attention has been devoted, however, to the silicon industry's shift from military to commercial markets in the early and mid‐1960s. Drawing on an examination of Fairchild Semiconductor, the firm that initiated this shift, this essay argues that the silicon industry's expansion into non‐military markets was indissociable from deep changes in manufacturing, organizational structures as well as component and system technologies. Special attention is devoted to the ways in which Fairchild created a user base for its products in the computer and consumer electronics industries by hiring engineers from these sectors and encouraging them to design components as well as applications for the firm's potential customers. This article also examines how Fairchild introduced mass production techniques from the automotive and electrical industries, delocalized its assembly operations to South‐East Asia, and developed new packaging techniques to meet the cost and manufacturing requirements of commercial users. This article is intended to contribute to recent interest in the role of user ‐ supplier relations in technological change and, more specifically, to the question of the pervasive use of silicon components across a wide range of industrial sectors, a central phenomenon in the history of industrialized economies since the 1960s.  相似文献

Propelled largely by direct investment via multinationals, Malaysia’s manufacturing sector has grown rapidly and is changing its output‐mix. In 1992, the share of high‐tech products in Malaysian manufacturing exceeded that of Japan, Korea or Taiwan. However, this ‘maturity’ was acquired without a strong research base. This article provides a framework which looks at the role of research and development (R&D) in conferring technological maturity and assesses the progress Malaysian manufacturing has made in this regard. The authors find that while multinationals have transferred many aspects of production, they have been slow in transferring R&D expertise. Neither has indigenous innovation filled this gap. Consequently, the long‐term sustainability of the industrial transformation process in Malaysia is in jeopardy. The article concludes with suggestions for corrective policies.  相似文献

Communities living on remote islands are often viewed as among the most exposed and vulnerable to climate change impacts. This study uses the Sustainable Livelihoods Framework to investigate how indigenous communities living on two physically different islands in Torres Strait, Australia, experience what they consider to be the impacts of climate change in relation to their daily lives. During this process, a series of natural, physical, and socio‐cultural limits and barriers to climate change adaptation were identified on Boigu, a low‐lying mud island inundated by the sea during high tides and storm surges. As a volcanic island, Erub's elevation is higher but significant community infrastructure, housing, and cultural sites are located on the low coastal fringe. No immediate limits to climate change adaptation were identified on Erub, but physical and socio‐cultural barriers were revealed. Limits to climate change adaptation occur when adaptation actions fail to protect the things valued by those affected, or few adaptation options are available. Barriers to climate change adaptation may be overcome if recognised and addressed but can become entrenched limits if they are ignored. Within the participating communities, such limits and barriers included (a) restricted adaptation options due to limited access to particular livelihood assets; (b) difficulty engaging with government processes to secure external support; and (c) people's place‐based values, which evoke a reluctance to relocate or retreat.  相似文献

Historical Epistemology: On the Diversity and Change of Epistemic Values in Science. Historical epistemology involves the claim that the system of scientific knowledge is not determined by the observations but is also subject to epistemic requirements that may change in the historical process of doing research. As a result, the system of knowledge is path‐dependent in that its shape is contingent on epistemic choices made at certain historical points. I attempt to elaborate this approach by drawing attention to the double role of epistemic values. First, such values create relations of significance and thereby contribute to directing research into certain avenues. Second, they are also important in the process of confirmation in that they entail that certain forms of agreement with the facts are superior and preferable to other such forms. Some epistemic orientations and reorientations can be reconstructed as arising from an interaction with nature, but others are based on commitments to the kind of knowledge we appreciate. The epistemic authority of science is created in large measure by rules of the scientific community that express how to deal with knowledge claims.  相似文献

The French–Portuguese Ethnological Mission to Portuguese Timor (1966/1969) financed by French and Portuguese research bodies and initially directed by Louis Berthe was the first mission that conducted lengthy and thorough ethnographic research in East Timor vernaculars and with East Timorese communities. Using personal and scientific archives, printed and oral sources, this article analyses the mission’s background, the role of Ruy Cinatti (a Portuguese poet, former colonial official in Timor and anthropologist trained in Oxford) in its launch, and its political and scientific context. The mission, undertaken during the Portuguese late colonial period and subject to the Portuguese authorities’ approval and surveillance, marked East Timor as a site of anthropological inquiry into the Anthropology of European tradition produced in Southeast Asia, affiliated to post-war structuralism. This case study throws light on individual agency, Portugal’s shortcomings in modern anthropology training, the international competition for Portuguese Timor as part of the Indonesian “field of ethnological study” and the transnational connections in its construction in the era of decolonization.  相似文献

The article surveys the findings and debates about “technological unemployment” carried out in the 1920's and 1930's in the United States. The huge productivity increases of the 1920's had sizable labour‐displacing effects, which were not matched by the job‐creating trends of prosperity. Unemployment was therefore a sizable and observable phenomenon as early as the late 1920's, while manufacturing employment shrank. After 1929, it was found that the Depression had hit production and investment hard, but productivity per man‐hour continued to increase. This meant that, because of the increases in population of working age and because of technological progress, in the late 1930's it would have been necessary to outgrow the levels of investment and production of 1929 in order to bring unemployment down to the 1929 rate. Even the recovery of 1937 remained much below those levels: the cause was seen in the behavior of large, concentrated industrial firms that administered prices and only applied technological advances in order to reduce costs. Their limited spending did not foster enough demand to move the economy out of the slump. The recovery was eventually brought about not by spontaneous, market‐driven economic behaviour, but by the deus‐ex‐machina of war‐induced Government spending.

A separate study of the theories of technological progress out‐distancing the job‐creating trends of prosperity is in preparation.  相似文献

Salmon farming has been an unprecedented success. It has provided employment and incomes, and has revived isolated communities. Europe maintains its dominance in salmon farming, but other countries such as Chile and Canada are becoming important producers. The paper describes the development of the industry in Europe, with an emphasis on its lessons for policy‐makers.  相似文献

Andalucia is a southern European LFR (less‐favoured region) with a high degree of self‐government that has allowed it to design its own R&D policies that complement those implemented throughout Spain and the European Union (EU). Recently the Regional Government passed the Third Andalucian Research Plan 2000–2003, an R&D planning instrument that, as has become customary in previous Plans, attributes considerable budgetary weight to the scientific aspects of the science–technology–industry system (Andalucia allocates more of its own resources to promoting research than any other region in Spain). This paper provides deeper insight into the role played by science in driving the technological development of Andalucia, one of the LFRs of the EU. The aim was to answer five fundamental questions: How is basic science utilized by industry in Andalucia? Which sectors are the most dynamic in the employment of scientific know‐how? Which scientific fields are most in demand by industry? Which types of institution utilize scientific knowledge most profusely? What delay is there in incorporating science into technology? The methodology that has been applied for investigating the links between science and technology is based on scientific citations in patent documents (NPC). The results in this article provide relevant information about the interconnection of scientific and technological systems and thus constitute a good point of reference for the development of future R&D plans.  相似文献

Some authors assigned the Indo‐Europeans a mirror‐like role which allowed them to understand their own position with respect to contemporary Christian values. After dealing briefly with the writings of J.G. Herder, I shall evoke a certain number of questions which oriented the research of E. Renan, F.M. Müller, A. Pictet and R.F. Grau. The works of the latter authors expounded fabulous genealogies, organizing them into explanatory systems that radically opposed Hebrew monotheists to Indo‐European polytheists. Thus, depending on whether they had used the Semites or the Indo‐Europeans as their starting‐point, they concluded that monotheism or polytheism, respectively, was the archaic source of human thought. The goal on their horizon was a ressuscitated West, forever in the forefront of progress, often simultaneously Christian and scientific. If this type of historiographic analysis is urgently needed at the present time, its purpose is not to provide a grid for distinguishing “truth”; from “falsehood,”; but rather to grasp a set of scholarly traditions within its own channels of transmission.  相似文献

Once the poster child for government-sponsored overfishing, New England by 2005 had become a fishery conservation success story. This article develops and deploys a problem-definition framework to explain the dramatic shift from a permissive to a protective fishery management regime in New England. I argue that neither new and improved scientific information nor pressure from powerful commercial interests caused government officials to modify their approach to fishery management. Instead, environmentalists used lawsuits to threaten fishery managers' autonomy and thereby forced them to replace fishers' risk-tolerant definition of the problem with environmentalists' more precautionary one as the basis for management. Environmentalists had legal leverage because they were able to demonstrate convincingly a substantial discrepancy between what the agency's governing statute required and what managers actually did. Two factors were critical to environmentalists' success: a compelling and credible scientific story about the relationship between fishing and the health of fish stocks, and an explicit conservation requirement in the language governing fishery management.  相似文献

Conventional approaches to development in areas that are experiencing economic decline invariably focus on business growth through interventions such as incentives, infrastructure development and job readiness training. This paper reports on a pilot project aimed at developing an alternative approach to community and economic development in the context of the Latrobe Valley, Victoria, a resource region that has experienced downsizing and privatisation of its major employer, the state‐owned power industry. The project was shaped by a poststructuralist concern with the effects of representation. It sought to challenge familiar understandings of disadvantaged areas, the economy, community and the research process in order to open up new ways of addressing social and economic issues. The resulting four‐stage research project was informed by the techniques of asset‐based community development and action research, as well as by discourses of the diverse economy and communities of difference. During the two‐year span of the project, four community enterprises were developed. The varying degrees of success they have met with in the four years since the project concluded highlight the critical role of local agencies such as the council in providing ongoing support for such endeavours.  相似文献

ABSTRACT Becoming an object of touristic interest is only one of a series of ways that Aboriginality is being transformed in contemporary Australia, as the space opens up for individuals and groups to reposition themselves as Aborigines within the nation, with a distinctive culture in various forms. The nation's appetite for Aboriginal ‘culture’, within desirable limits (Povinelli 2002) and energised by a sentimental politics (Cowlishaw 2010), continues to grow. There is, however, a destructive flip side to the politics of difference being played out within Aboriginal societies. This is evidenced by the many battles for access to or control of ‘cultural’ resources for their commercial benefits or collective survival value. In many places communities or groups are faced with the terrible choice of distinction or extinction (Comaroff & Comaroff 2009). That is, they must find, and make alienable, something distinctive about themselves or face collective extinction. How one Aboriginal community is responding to these threats and challenges is the subject of this paper. This paper also adds to the growing literature on ethno‐commercialisation by focusing on the central role of language in these processes.  相似文献

This article examines the Finnish industrial and trade fairs held in the Soviet Union in the context of Finnish–Soviet trade and scientific–technical cooperation in the 1950s and 1960s. While primarily focused on fairs, it also discusses different activities that accompanied them, such as lectures, visits, and negotiations between Finnish traders and Soviet officials and specialists. This study illustrates how such first-hand contact played an important role in Finnish–Soviet communications. First, they helped Finnish producers showcase their goods and technologies directly to Soviet buyers in various ministries and organizations. Second, these contacts included diverse activities such as face-to-face contacts, lectures, and seminars, being a means of technology transfer from Finland to the USSR . Finally, although they were commercial interactions without explicit ideological purposes – like many international exhibitions of the last century – Finnish fairs demonstrated a technological gap between Finland and the USSR.  相似文献
