This study analyses the development of the use of unpublished source material in Swedish doctoral theses in history, 1959–2015. The results show that the proportion of theses which rely on such materials has dropped in relation to the level that existed up to and including the year 2007. From having dropped below 90% only twice during the time period 1959–2007, the average for the years 2008–2015 is 77%. There are several explanations as to why this decline in use of unpublished source material has occurred. An initial explanation is that more doctoral theses are now published within the subdiscipline of historical science, in which, for example, history didactics and uses of history are included. History didactics and uses of history have gained more ground within the overall field of historical research during the last 10 years. The next-to-lowest figures are found in the category history of ideas, culture, and opinion history; a category which during the time period 2008–2015 remained at a fairly constant share of the total number of doctoral defences in history in Sweden in relation to the situation at the beginning of the 2000s.  相似文献

Some French writers, most notably Jean-Baptiste Duroselle and André Tardieu, have argued that French strategic interests during the early decades of the twentieth century had been seriously harmed because, alone among the Great Powers of Europe, France lacked a ‘diaspora’ in the United States. As a result of this, they have claimed, France had no advocacy group prepared to defend the interests of the European ‘kin state’ at a time when France’s great rival, Germany, was amply endowed with a sizeable demographic presence in the United States, willing to speak out in defence of Germany and its foreign policy. Moreover, a second large European diaspora had become established in the United States, whose numbers would swell after the mid nineteenth century: the Irish. Not necessarily committed to promoting German interests, the Irish-Americans did militate strongly and consistently against British interests, such that by the time France and Britain had become close security partners preceding and during the First World War, what worked against British interests would also work against French ones. This article constitutes a critical examination of the Duroselle-Tardieu thesis regarding France's allegedly ‘missing’ diaspora, and cautions against attributing too much geo-strategic influence to either the German-American or Irish-American ‘lobby’.  相似文献

A series of dramatic mid‐air collisions during the late 1950s caused the United States to embark on a reconstruction of its air traffic control system. In pursuit of the concept of ‘positive control’ over all aircraft, the Federal Aviation Agency modified and deployed military technologies under orders to eliminate these highly public catastrophes. In the process, it curtailed one of flight's great dreams, freedom of the skies, imposing technological and procedural requirements on fliers wanting access to urban airspace. Resistance from private fliers produced modification of some of the agency's plans, causing it to adapt its planned airspace structures to permit private fliers limited access without having to submit to the control system.  相似文献

ABSTRACT

Between the second half of the nineteenth century and the 1930s, German piano making changed from a craft to an industry. Nevertheless, piano makers still needed specific working knowledge to produce quality instruments. This knowledge was bound to individuals and transmitted informally from one person to another. The piano makers took working knowledge as the core of their practice. But in the shift to industrial methods of production, the key question was how to translate working knowledge into formal knowledge—to articulate what such knowledge meant and how it might be applied. Using the case study of the German piano making factory Grotrian-Steinweg, I show how the piano maker Kurt Grotrian used his notebooks to grapple with the problem of formalizing his working knowledge. At this company, an acoustic laboratory was established, in whose reports formalized knowledge was stored due to the transition of piano making from a craft to an industry.  相似文献

Abstract: This essay starts from the presumption that “the communist hypothesis” is still a good one, but argues that the idea of communism requires urgent re‐thinking in light of both the “obscure” disaster of twentieth century really existing socialism and the specific conditions of twenty‐first century capitalism. I explore the contours of the communist hypothesis, chart the characteristics of the revolutionary capitalism of the twenty‐first century and consider how our present predicament relates to the urgency of rethinking and reviving the communist hypothesis. Throughout, I tentatively suggest a number of avenues that require urgent intellectual and theoretical attention and interrogate the present condition in light of the possibilities for creating communist geographies for the twenty‐first century.  相似文献

Documentation of cutmarks is standard protocol in contemporary zooarchaeology. However, there is currently no consensus about how to best quantify them. This study examines differences in cutmark patterning using two approaches: 1) by means of an experiment, comparing a control cutmark pattern to ten simulated highly fragmented sets of front and rear limbs using %NISPcut as the quantitative unit, and 2) by quantifying an archaeological faunal assemblage using both the number of identifiable specimens (NISP) and the comprehensive minimum number of elements (cMNE). Results reveal significant differences in cutmark patterning between the control set and the simulated fragmented sets. Additionally, the ordinal-scale frequencies of cutmark anatomical portions (proximal, shaft, distal) are inconsistent and fluctuate across the simulated sets. Results of the zooarchaeological analysis show that differences between the two quantification methods are significant. In general, this study suggests that on heavily fragmented assemblages, interpretations of butchering behavior based on cutmark patterning are influenced by the chosen unit of quantification. Overall, using NISP as the quantitative unit provides inconsistent results, whereas, by alleviating the effects of high fragmentation, cMNE is more reliable.  相似文献
