Fifty-three copper-based metal fragments, recovered from the Robitaille site in southcentral Ontario, were analysed by neutron activation to establish their chemical make-up and to sort them by their trace elemental chemistries. Three different European copper samples, one brassy copper and 48 brass samples with five different chemistries were found. As few as eight trading actions may account for all of the recovered European metal fragments.  相似文献

A sample of 82 anterior teeth from Krapina (Croatia) was studied using a light binocular microscope and a scanning electron microscope to document the presence of non-dietary dental scratches. The patterns of distribution, location and orientation of these marks suggest two different aetiologies: scratches on the labial-occlusal enamel border appear to be related to the action of clenching abrasive materials between teeth, while the scratches primarily in the centre of the labial face correspond to cutmarks as described by other researchers. These scratches may have been produced when flake tools involved in processing materials held between the anterior teeth came into contact with the labial enamel face. Alternatively, they may simply reflect some consistent operation which pulled hard objects across the labial surfaces of the anterior teeth. In either case, the marks on the central face of the labial surface provide evidence for manual dexterity in the Neanderthals. Of the seven Krapina individuals which show a predominant pattern, one shows a pattern of left oblique marks, while six provide evidence of right-handedness. Coupled with other Neanderthal or Upper Pleistocene individuals with these patterns, right-handedness is the dominant pattern in 90 per cent of the documented cases. One complicating factor in the analysis of these scratches in the Krapina hominids is that marks of a similar morphology are found in several anterior teeth of Ursus spelaeus from the site. While resembling the marks on the hominid incisors, the scratches on the bears lack a dominant orientation on the labial face and appear to be more variable in their widths. Despite the occurrence of some similarities in the enamel scratches between ursids and hominids at Krapina, the study of anterior dental marks provides information about manipulative activities which are unique to ancient humans. © 1997 by John Wiley & Sons, Ltd.

The age of Neanderthal remains and associated sediments from El Sidrón cave has been obtained through different dating methods (14CAMS, U/TH, OSL, ESR and AAR) and samples (charcoal debris, bone, tooth dentine, stalagmitic flowstone, carbonate‐rich sediments, sedimentary quartz grains, tooth enamel and land snail shells). Detrital Th contamination rendered Th/U dating analyses of flowstone unreliable. Recent 14C contamination produced spurious age‐values from charcoal samples as well as from inadequately pretreated tooth samples. Most consistent 14C dates are grouped into two series: one between 35 and 40 ka and the other between 48 and 49 ka. Most ESR and AAR samples yielded concordant ages, ranging between 39 and 45 ka; OSL dating results permitted adequate bracketing of the sedimentary layer that contained the human remains. Our results emphasize the value of multi‐dating approaches for the establishment of reliable chronologies of human remains.  相似文献

This paper is based on a recent decision of the Supreme Court of Canada that will allow the Province of Quebec to restructure the system of education, from one based on religious affiliation to one based on language of instruction. The paper sets forth a number of geographic implications of such a reform, including the historic, demographic, linguistic, political, and territorial aspects of the Education Act of Quebec, known as Bill 107. While the change to linguistic-based boards is applauded, there is no clear understanding of what the new map of school board territories will look like, yet the implications of this decision are far-reaching.
Cet article est basé sur une récente décision prise par la Cour suprême du Canada qui permettra au Gouvernement du Québec de restructurer le système d'éducation, c'est-à-dire de passer d'un système fondé- sur l'appartenance religieuse à un système fondé sur la langue d'enseignement. L'article démontre quelques une des répercussions géographiques d'une telle réforme, en plus des aspects historiques, démographiques, linguistiques, politiques et territoriaux de la Loi sur l'instruction publique du Québec ou Loi 107. Même si la mise sur pied de commissions administratives à caractère linguistique est approuvée, l'élaboration de la nouvelle carte des territoires desservis par chacune des commissions scolaires demeure ambigue, mais le retentissement de cette décision est d'une portée considérable.  相似文献

This article examines the Egyptian Muslim Brotherhood (MB) movement's stand on the South Sudan question. The aim here is to contribute to the ongoing debate over the MB's moderation. Throughout the civil war in Sudan, the MB consistently objected to South Sudanese secession. Yet, while it had traditionally framed its objection in religious terms, describing the South Sudanese struggle as a Christian conspiracy against Islam, in the decade preceding South Sudan's declaration of independence it moved to base its opposition on more practical grounds, revolving around issues such the absence of democracy, stability and infrastructure in South Sudan. This correlated with wider shifts in the MB. Since the 1990s, the movement has claimed to have undergone a transformation, adopting a moderate, pro‐democratic stance. These statements persuaded many scholars that the MB has come to represent political moderation in both its domestic and international agenda. More recent works on the movement, however, have come to question the MB's moderation hypothesis, suggesting that even though the movement has changed its discourse and some aspects of its activism, this could not be seen as a linear process of moderation. This article uses the South Sudan case to further support this critique from a foreign policy perspective. It demonstrates that even though the MB changed its tactics and discourse, its goals remained unchanged— even when the circumstances and the normative environment changed dramatically. Moreover, it shows that at times of crisis, the liberal discourse gave way to the old‐fashioned radical discourse of previous decades.  相似文献

Torres et al. (2010 ) published a series of radiocarbon, AAR, ESR and OSL dates from the site of El Sidrón, northern Spain, which is notable for the discovery of the partial remains of 12 Neanderthals. Whilst the non‐radiocarbon methods suggested an age beyond 32 600–46 300 years, direct radiocarbon dates on the human fossils were inconsistent, ranging between 10 000 and 50 000 bp . This study uses the ultrafiltration pre‐treatment protocol to obtain a date of 48 400 ± 3200 bp (OxA‐21 776) on a bone fragment and confirm the antiquity of the Neanderthal assemblage. Moreover, it demonstrates the comparability of the ultrafiltration and ninhydrin bone radiocarbon pre‐treatment protocols, and highlights the need for appropriate screening methods where valuable collections with poor biomolecular preservation are sampled for collagen extraction.  相似文献

This paper analyses the uses made by hagiographers and chroniclers of the character of Desiderius of Vienne. Desiderius, a bishop in Merovingian Burgundy, was the protagonist of two seventh‐century Lives, and appears in numerous other hagiographical works and chronicles. Desiderius also figures prominently in works composed within the context of Columbanian monasticism, most notably Jonas of Bobbio's Vita Columbani. His appearance in these works paints a multifaceted picture not only of his own political activities, but also of the agendas of the hagiographers themselves, who exploited his literary image to further their ends. It is the contention of this paper that despite the frequent mentions of Desiderius in Columbanian compositions, he did not, in fact, play a part in the Columbanians' success.  相似文献

Land degradation is the result of the intersection of a complex set of biophysical and socio‐economic factors. The capacity of an individual or community to address land degradation is likewise constrained. While it is quite possible for professionals and learners to grasp the main issues around land degradation from a theoretical perspective, internalising the reality of what it means to be the resource degrader is more difficult. We have developed two active learning methods that aim to address this problem. The first is the African Catchment Game, a role‐playing game based on Graham Chapman's Green Revolution Game, adapted for the southern Africa context and incorporating a land degradation component. In this game participants play out the complex dynamics of rural‐urban‐global linkages against a background of environmental hazards. The second is based on Save the Children Fund's RiskMap computer simulation that models risk in terms of rural livelihoods for different income groups. Ethiopia is used as the example. This paper evaluates the two active learning techniques as tools for exploring the relationships between land degradation and poverty through an evaluation of participants’ experiences. The analysis shows clear potential for developing alternative teaching curricula that are aligned to our theoretical understanding.  相似文献

ABSTRACT. Over the past fifteen years, Hungarian nationalists have been redefining membership in the Hungarian nation to include all Hungarians in the region, irrespective of citizenship. This deterritorialised notion of the nation has been given increased discursive and institutional legitimacy. But ethnic Hungarians from Romania who have gone to Hungary in search of work have not discovered national unity. Rather, the vision of national inclusion preferred by elites has been met by the reality of economic and national exclusion engendered through labour migration. The migrants' national self‐understandings have taken shape not in accordance with the wishes of nationalist elites, but rather in response to the economic imperatives of labour migration. Rather than deducing the salience of national unity from its political privileging, the purpose of this paper is to explain how national disunity is experienced, constituted and reproduced in the context of ethnic Hungarian labour migration.  相似文献
