This article traces the implementation, execution, and results of the French Ministry of Armaments’ scrap iron collection drive from September 1939 to June 1940. This collection drive was a belated effort to mobilize patriotic sentiment and raw materials for France’s war effort. By the late 1930s, the French government realized that it did not have — and, more importantly, would not be able to acquire — enough metal to meet ambitious armament plans. In September 1939, Raoul Dautry, the Minister of Armaments, began moving toward a controlled economy by setting up central distribution organizations, preventing the movement of stocks, and organizing the national scrap drive, modelled, in part, on Germany. Despite a rural distrust of the state and cases of individuals hoarding metal, most people responde­d to the call. Yet logistical difficulties in finances, manpower, and transportation hampered efforts. By May 1940, half of the 85,000 tons collected remained piled on the platforms of railway stations. With the invasion, the Germans immediately confiscated this metal. With the defeat of France, this failed drive came to symbolize France’s defeat and humiliation, as well as the impotence of the Third Republic.  相似文献

This study presents research on how an integration of use-wear analysis with protein residue analysis can produce new results on prehistoric tool use and function. Thirty flint artefacts from an Early Neolithic TRB site in south Sweden were analysed for both use-wear and protein residues. The results show a positive correlation between the two methods. The Early Neolithic tools analysed were primarily used to process fish.  相似文献

Samples of dental calculus were taken from 11 human individuals buried at Nemrik 9, a Pre-Pottery Neolithic site in Northern Iraq. All of them represented the time span of ca. 9100–8600 bp. In total, 95 microfossils were retrieved from these samples, including 70 phytoliths, 9 starch granules or clusters of starch, 3 pollens, and 1 xylem fragment. Most microfossils could be attributed to C3 cool season cereals, most likely wheat and barley, which is consistent with previous knowledge about the composition of crops in early farming communities living in the Fertile Crescent. In addition, three phytoliths and one starch granule typical of C4 warm season grasses were recovered including one subangular and faceted starch granule, which might derive from a native grass, but is not diagnostic of any genus. Prior to assigning diagnostic status to this starch, exhaustive reference work on native grass seeds is necessary. The presence of one Phragmites phytolith suggests non-alimentary processing of reeds using teeth or perhaps using the stem of this grass as a toothbrush or toothpick.  相似文献

Ninety-nine obsidian artifacts from fortified and non-fortified sites in the Pambamarca region of northern Ecuador were analyzed with XRF to examine patterns of procurement of obsidian by soldiers in the Inka army and by the local Cayambes who were resisting Inka conquest. The results show that the Inkas acquired material from several different sources, a pattern consistent with provisioning by subject peoples in partial fulfillment of labor obligations. The Cayambes also acquired material from multiple sources, although they may not have directly procured material from all of the sources because the external boundary of Inka territory bisected the region of obsidian sources. That frontier may have prevented the Inkas from accessing one source, Callejones, from which the Cayambes acquired some of their obsidian. In addition, the Inkas were acquiring some obsidian from the Yanaurco-Quiscatola source, which had been previously abandoned around AD 1000.  相似文献

How can partisan mapmakers enact a partisan gerrymander in the presence of risk-averse co-partisan incumbents who wish to keep most of their constituencies intact? Until now the literature on redistricting has focused on how redistricting affects the geography of partisan support, that is, the underlying partisan balance of electoral districts. We posit that this emphasis on partisanship misses half of the story. Partisan mapmakers have another tool at their disposal: the fostering of population instability that may not affect a district's partisan balance. By examining all redistricting plans enacted in 2001–2002, as well as three case studies, we show that partisan mapmakers strategically foster population instability, which poses problems for incumbents in a way that may not be apparent when looking exclusively at the effects of redistricting on partisanship. Our results show how partisan mapmakers simultaneously achieve two goals: enacting an “optimal gerrymander,” which strengthens some opposition-party incumbents, while inducing instability and reducing the personal vote of those same incumbents. We also show that so-called “neutral” redistricting plans are successful in disregarding incumbency. Finally, our results suggest another mechanism that explains why the 2002 congressional elections in the U.S. produced little competition.  相似文献

This article explores Salāmān va Absāl, one of seven poems which comprise Jāmī's collection of long masnavīs, known collectively as the Haft aurang. The work, which gained some renown outside Iran due to the English version of Edward FitzGerald, has nevertheless received little attention in modern scholarship. The few investigations of Salāmān va Absāl, moreover, have dwelled on its narrative, which tells the story of the carnal attraction of a prince for his wet-nurse, and never situated the work in its historical context or examined its political content. In addition, the allegorical symbolism of the tale, especially its depiction of key stages of the Sufi path, such as the act of repentance, has not been discussed in terms of representing a work of mystical advice. With these concerns in mind, the present article discusses the possibility that the political elements in Salāmān va Absāl complement the advice it gives on becoming a Sufi. Seen from this perspective, it would appear that Salāmān va Absāl correlates the notion of the just ruler to the Sufi concept of the “Perfect Man” to the extent that Jāmī presents the Sufi-king as the ideal medieval Islamic ruler. By implication, the work advises its royal patron, Sultān Ya‘qūb, to repent and embark upon the Sufi path, doing so, Jāmī intimates, would lead Ya‘qūb to realize his rank as God's “true” vicegerent.  相似文献
