The persistent uncertainty on the classification of the “new” glume wheat found in Neolithic and Bronze Age sites from Greece and other European settlements might be resolved only through analysis of its ancient DNA. Tools able to discriminate among different Triticum species on the basis of scarce, very damaged DNA, are therefore essential. While current attempts concentrate on DNA fragments sequencing and comparison, in some instances PCR-based selective amplification techniques might offer a cheaper and quicker alternative. The purpose of this research was therefore the identification of species-specific primers, able to distinguish caryopses of Triticum timopheevii subsp. timopheevii from those of Triticum turgidum subsp. dicoccum. Primers and their working conditions were defined and optimized using DNA from modern accessions. The ribosomal primers ITS1 tim and ITS2 tim, and the nuclear primer acetyl-coenzyme A tim clearly discriminated the sequences of Triticum timopheevii from other species. Finally, Neolithic charred wheat grains found in the sites of Sammardenchia (Pozzuolo del Friuli, Udine) and La Marmotta (Lago di Bracciano, Roma), belonging to the “new” wheat type or to emmer, were tested with the three selected primers. However, the results were not conclusive, because the samples analysed were apparently too degraded to yield useful DNA.  相似文献

This paper explores the third-world left in Los Angeles, from 1968–1978. In it I examine the political ideology and foci of one organization for each of the major racial/ethnic groups of the time: African Americans (Black Panther Party), Chicanas/os (El Centro de Accion Social y Autonomo [CASA]), and Japanese Americans (East Wind). In addition to reclaiming this relatively unknown history, I seek to explain the differences in the various organizations by analyzing them within the context of differential racialization. I argue that the distinct nature of each organization is at least partly due to the particular racial position of each racial/ethnic group within the local racial order.  相似文献

Much of the debate surrounding the inclusion of women in the study of international politics, particularly in reflections of war, promotes passive representation. State-sanctioned images of non-combatant women in supportive wartime roles reflect, rather than confront, traditional conceptualisations of 'legitimate knowledge' and ways of knowing. Therefore, estimates that 30,000 women were raped during the war in Bosnia shocked the international community. Yet it shouldn't. War rape is as old as war itself. This article looks at why, and how, traditional forms of theorising about international politics fails to identify or vocalise the violent insecurities of women in domestic and international space, thus ensuring women's silence. It also draws on alternative ways of knowing to confront the tradition and to un/recover the experiences of women.  相似文献

During the Neolithic period, the Chengdu Plain was a key region where two important crops, rice and millet, were cultivated together. Millet was probably introduced from north-western China c.3500–3300 cal. bce , and rice came from the Middle Yangtze River c.2600 cal. bce . In this study, human and faunal remains, as well as charred crop grains, were collected from the Yingpanshan (3300–2600 cal. bce ) and Gaoshan (2500–2000 cal. bce ) sites where the dominant crop was millet and rice, respectively. Carbon and nitrogen isotope analyses were conducted on human bones and the ecofact samples in order to reconstruct the subsistence at the sites. The results indicate that the diets of two individuals recovered from the Yingpanshan site consisted of both C3- and C4-based foods, predominantly the former. By contrast, Yingpanshan pigs consumed a large quantity of C4 fodder. This result, combined with the ecofact evidence, suggests that millet was the main crop at the Yingpanshan site. It also highlights the fact that the two Yingpanshan individuals might be non-locals and/or belonged to later periods. On the other hand, the diet of the Gaoshan community was dominated by C3-based foods. When considering the archaeobotanical evidence at Baodun, a site contemporaneous with and near to the Gaoshan site, it can be stated that rice was an important food resource for the Gaoshan community. This study also suggests how crops were managed at the two sites. The Yingpanshan people might have used manure for growing millet. Both manuring and irrigation might have also been practised by Gaoshan's rice farmers. However, more studies are required to understand the extent of manuring and irrigation in their agricultural economies.  相似文献

Historical, artefactual and place‐name evidence indicates that Scandinavian migrants moved to eastern England in the ninth century AD, settling in the Danelaw. However, only a handful of characteristically Scandinavian burials have been found in the region. One, widely held, explanation is that most of these Scandinavian settlers quickly adopted local Christian burial customs, thus leaving Scandinavians indistinguishable from the Anglo‐Saxon population. We undertook osteological and isotopic analysis to investigate the presence of first‐generation Scandinavian migrants. Burials from Masham were typical of the later Anglo‐Saxon period and included men, women and children. The location and positioning of the four adult burials from Coppergate, however, are unusual for Anglo‐Scandinavian York. None of the skeletons revealed interpersonal violence. Isotopic evidence did not suggest a marine component in the diet of either group, but revealed migration on a regional, and possibly an international, scale. Combined strontium and oxygen isotope analysis should be used to investigate further both regional and Scandinavian migration in the later Anglo‐Saxon period.  相似文献

ABSTRACT

This article explores conceptual frameworks for understanding Korea’s contemporary cultural policy by looking into the historical transformation of the culture-state-market relations in the country. It argues that Korea has become ‘a new kind of patron state’, which emulates the existing patron states in the West firmly within the statist framework and ambitiously renders government-led growth of cultural industries (and the Korean Wave) as a new responsibility of the state. The formation of Korea’s new patron state has been driven by a ‘parallel movement’ consisting of democracy and the market economy, which has defined the political and socio-economic trajectory of Korean society itself since the 1990s. Democracy has been articulated in cultural policy as cultural freedom, cultural enjoyment and the arm’s length principle; meanwhile, the market economy of culture has been facilitated by a ‘dynamic push’ of the state. After discussing the parallel movement, the article points out the tension, ambiguity and contradiction entailed in cultural policy of the new patron state.  相似文献
