A variant of the structural contingency model is applied to the post-war experience of the British shipbuilding industry to show how technological change has affected the market for ships and compelled shipbuilding firms to adopt a number of responses. These include changes in industrial organization and the promotion of government intervention. Some of the ensuing outcomes are explored in detail by focusing on the industrial impact of the introduction of large tankers and standard ship designs. The regions that have benefited from the interaction of technological change and market demand are also identified.  相似文献

Metallography and neutron activation analysis have been used to investigate copper artifacts from 19th century archaeological sites associated with the “Copper Inuit” of the west-central Canadian Arctic. A knowledge of the source of the copper from which the artifacts were manufactured - native (local) copper or European (exotic) copper - is important, for example, to studies of the effects of European contact on utilization of native copper and on the general lifestyle of the Copper Inuit. Trace element analysis by neutron activation using the SLOWPOKE reactor has allowed local native copper, from the Coppermine River and Victoria Island, NW Territories, to be clearly distinguished from 19th century European smelted copper, which was found to contain higher concentrations of arsenic, antimony, nickel and selenium. Moreover, optical and scanning electron metallography revealed significant microstructural differences between native copper and the 19th century smelted copper. As a consequence it was possible to differentiate between native copper archaeological artifacts and those produced from smelted copper.  相似文献

Colin Koopman's excellent Genealogy as Critique argues that Michel Foucault's genealogies—and, in fact, his archaeologies—should be read as historical accounts of the emergence of particular “problematizations.” The idea of a problematization, which Foucault introduces late in his career, has two sides. First, there is the idea that the situation whose emergence a genealogy traces is problematic in the sense of being fraught or dangerous. Second, by tracing the genealogy, Foucault problematizes the situation itself, showing how it calls for attention. Koopman argues that Foucault's genealogies are not themselves normative, but they instead outline situations or practices in a way that allows for normative investigation and political intervention. What is required, then, are normative approaches that complement Foucault's genealogies. Koopman argues that Foucault's own late discussions of self‐transformation are inadequate to fully accomplish the task; they need to be complemented by recourse to Deweyan reconstruction or Habermasian normative reflection. However, and in turn, such reflection cannot be had on an absolutist ground but rather must be seen as historically contingent, universalizing rather than universalist in Koopman's vocabulary. I argue that there are several reasons to think that the strong separation between genealogy and normative posited by Koopman may be too strict. Foucault's rhetoric, his choice of certain problematizations, and Koopman's own commitments to problematizations as requiring attention all seem to point toward a more intimate, although admittedly implicit, relation between genealogy and normative positions in Foucault's work.  相似文献

In this article, the authors describe a collaboration of the Minnesota Population Center (MPC), the U.S. Census Bureau, and the National Archives and Records Administration to restore the lost data from the 1960 Census. The data survived on refrigerated microfilm in a cave in Lenexa, Kansas. The MPC is now converting the data to usable form. Once the restored data are processed, the authors intend to develop three new data sources based on the 1960 census. These data will replace the most inadequate sample in the series of public-use census microdata spanning the years from 1850 to 2000, extend the chronological scope of the public census summary files, and provide a powerful new resource for the Census Bureau and its Research Data Centers.  相似文献

To investigate potential human impacts on California Channel Island shellfish stocks over the past 10,000 years, we measured 1718 owl limpet shells from 19 archaeological components on San Miguel Island. Inhabiting the middle intertidal zone of Pacific Coast rocky shores, owl limpets are slow-growing mollusks that can live for 30 years and reach lengths of over 100 mm. Recent ecological studies indicate that owl limpets are highly susceptible to heavy human predation, which results in reduced mean shell sizes among Lottia populations along the coasts of Alta and Baja California. On San Miguel Island, we identified a significant trans-Holocene reduction in mean owl limpet size, beginning more than 6500 years ago and accelerating at least 4400 years ago. Fluctuations in limpet size show no clear correlation with changes in sea surface temperature and marine productivity, suggesting that increased predation by growing human populations was primarily responsible for the reduction in Lottia size over time. Our results provide further evidence that prehistoric peoples significantly influenced nearshore fisheries long before the development of the commercial and industrialized fisheries of historic times.  相似文献

Recent scholarship has shown how conceptualisations of religion were not a given but the site of historical conflict in the creation of nation-states. In light of this insight, it is time to revisit the history of Britain's political engagement with the phenomenon of nationalism during the era of decolonisation. One important but under-studied case involves Britain's relationship with Muhammad Idris ibn al-Mahdi al-Sanusi (1889–1983) and the Sanusi brotherhood during the Second World War, a crucial phase in the evolution of Anglo-Libyan relations. Although the assessment of military exigencies and the calculation of strategic interests played an important part in determining Britain's attitude towards the Sanusi they do not tell the whole story. British support of Idris was also premised on the adaptability of the Sanusi Order and the probable reformulation of the role of Islam in the context of an emerging nation-state. By charting the evolution of the pro-Sanusi, pro-Idris case within British circles, this article highlights the interesting interaction between orientalism, religion and nationalism that shaped Anglo-Sanusi relations during the Second World War. While historians have long recognised the links between orientalism and formal imperialism there were also interesting connections between orientalism and nationalism that deserve equal consideration.  相似文献

In this paper, we expand upon a prior study [Surovell, T.A., Brantingham, P.J., 2007. A note on the use of temporal frequency distributions in studies of prehistoric demography. Journal of Archaeological Science 34, 1868–1877.] that explored the problem of taphonomic bias. Taphonomic bias refers to the tendency for younger things to be over-represented relative to older things in the archaeological record due to the operation of destructive processes like erosion and weathering. Using a database of radiocarbon dated volcanic deposits from Bryson, R.U., Bryson, R.A., Ruter, A. [2006. A calibrated radiocarbon database of late Quaternary volcanic eruptions. Earth Discussions 1, 123–124.], we develop an empirical model of taphonomic bias. In contrast to our prior study in which we modeled taphonomic bias as an exponential function wherein the likelihood of site loss remains constant through time, we argue that the probability of site destruction actually decreases with site age. We further demonstrate how this model can be used to correct temporal frequency distributions and extract demographic histories. We illustrate this approach using databases of radiocarbon dates from rockshelter and open-air sites in the Bighorn Basin, Wyoming, USA, and mammoths and humans in Siberia, Russia.  相似文献
