This essay uses material from the British Broadcasting Corporation (BBC) archives to show how space-related technoscientific activities played a key role in the development of BBC television. The essay focuses on a crucial period when this influential cultural institution transitioned away from radio as their primary broadcast medium in the 1930s and 1940s to reluctantly embrace television in the 1950s and 1960s. Space-related activities, including astronomy, cosmology, rocketry, aerospace engineering, astrophysics and interplanetary research, played a key role in the modernization of BBC television broadcasting in two intersecting ways. Space-related material provided informative, yet popular, programmatic material that helped BBC television compete in an increasingly commercialized media market, and, later, space projects supplied technologies that impacted on the mechanics of broadcast production and transmission. The profile and prestige of space as a topic, in particular, its visuality, the drama of exploration it presented, and its association with celebrity scientists like Bernard Lovell and Fred Hoyle, meant that such programming became a crucial business asset for the BBC and a professional asset for ambitious producers who saw its commercial potential. Following the launch of Sputnik in 1957, space technology became further intertwined with the development of British broadcasting as the fields of satellite communications and broadcasting transmissions infrastructure converged. In particular, BBC producers promoted the potential development of communication satellites within their television programming by portraying such satellites as plausible and necessary for the advancement of civilization, and most crucially, as a prospective British Space Race achievement. 相似文献

A metallurgically-oriented excavation in Area A at Tell es-Safi/Gath yielded evidence for iron and bronze production dating to the early Iron Age IIA. Two pit-like features, which differed considerably from one another in colour, texture and content, were excavated. Evidence shows that each feature represents a different in situ activity related to iron production, inferred by the presence of hammerscales, slag prills and slag. An upturned crucible was found on top of one of the features. Analysis of the crucible slag showed that it was used for bronze metallurgy. Tuyères, both round and square in cross-section, were found in and around the two features. The presence of the two industries together presents a unique opportunity to explore the relationship between copper and iron working. This is especially important against the background of the scarcity of evidence for iron production in the Levant during the early phases of the Iron Age. 相似文献

Western firms engaged in mass retailing and in product assembly make frequent changes to their global production networks (GPNs). Indeed, some GPNs show a tendency to hypermobility, which we define as a rapid switching of economic links among manufacturers, importers, and retailers. This theme is explored in the context of the Canadian bicycle industry where domestic production collapsed between 1980 and 2008, following a century of remarkable stability. After a period of flux when Taiwan was the key player, China has emerged as the dominant original equipment manufacturer (OEM) of bicycles sold in Canada, with big‐box stores accounting for the great majority of sales. We connect this increasing fluidity in supply arrangements and in the global organization of the industry with the governance of these GPNs. Several aspects of governance are considered, including the Sloanist practices of the largest Canadian retailers, and the activist role of the Chinese state in directing regional patterns of manufacturing in China. 相似文献

Abstract: This paper contributes to scholarship on health and environment by focusing on connections between human health and political economy of seafood. The contemporary rise of aquaculture is an effort on the part of the seafood industry to escape the contradictions of capital that create crisis in capture fisheries. Yet intensive aquaculture may also create human health problems that contribute to new crises. Aquaculture practices not only increase production of healthful fish, but also lead to fish burdened with chemical pollutants about which there are a variety of health concerns. These health concerns pose problems for producers who may not be able to sell contaminated seafood. By examining the intertwined biochemical and social processes that produce multiple natures (fish bodies, human bodies and the aquatic environment), the paper shows that concerns about health are not only an outcome of political economic processes, but are also an explanatory factor in these processes. 相似文献

One important extension of the IAD framework has been to the study of local public economies. These are multi‐organizational, multi‐level arrangements defined as the set of governmental jurisdictions, public and nonprofit agencies, and private firms that interact in various patterns to provide and produce public goods and services within a specific locality or region. Commonly, the localities or regions studied from this perspective have been U.S. metropolitan areas, often defined as a central city and its surrounding or adjoining county. Localities can be delineated, however, on various terms, and in the IAD framework, it is the geo‐physical nature of a locality that, in substantial part, drives the analysis. One of the strengths of the approach is its capacity to explain local variations in public organization as a function of the geo‐physical diversity of localities, while at the same time developing empirical generalizations and normative principles that apply across diverse regions. What, for example, might the organization and governance of a complex metropolitan area have in common with the organization and governance of a complex protected area, such as the greater Yellowstone eco‐region or the Adirondack Park? Construing both sorts of regions as local public economies can enhance our overall understanding of public organization at the same time that it permits a more nuanced understanding of diverse localities. Such work contributes to the ongoing IAD project of “understanding institutional diversity.” 相似文献

The article describes lithic industries of the Upper Paleolithic levels of Kulbulak, Uzbekistan, a key site in southwestern Central Asia based on materials from excavations at several sites in the western and northwestern Pamir– Tien Shan region (Kulbulak, Kyzyl-Alma-2, Dodekatym-2, and Shugnou). A new cultural and technological tradition is introduced, for which the authors suggest the name Kulbulakian. Its distinctive features are the bladelet technique and a microlithic set including backed pieces and triangular microliths. Stages in the evolution of the Kulbulakian tradition are reconstructed: origins, development, peak, and disappearance of the carinated technology. Industries belonging to this tradition have shaped the general appearance of the Upper Paleolithic in the area in question. 相似文献

The scholarly focus on the production of space necessitates a thorough reassessment of the static categories employed in the analysis of spatial processes. Emphasizing space as a process, this essay calls attention to the recent implication of Madrid's Retiro Park in larger processes of capital accumulation. At the same time, it highlights the insufficiency of the tempting yet problematic distinction between public and private space that obtains in easy solutions to the struggles over city-space. As many critics have pointed out, there is design flaw in the idea of public space—it can never explain how a given space, such as a park, comes to be free of the ‘private’ (personal and structural) interests operating throughout its societal context. The story of the Retiro ultimately foregrounds the pivotal role of city-space in the drive for capitalist intercity-competition and suggests that the latter process is insufficiently confronted by idealized notions of the role truly ‘public’ spaces might play in radical democracy and citizenship. 相似文献

Scottish carrier trade declined rapidly in the period 1820–60, but the pattern is complex and growth co‐exists with contraction. Total volume of traffic is halved, but in areas peripheral to the thin rail net there are increases. Glasgow was the main carrier centre, and saw not only contraction but a change from regional to local functions. 相似文献
