Considerable progress has been made in recent years in the study of the Lower and Middle Paleolithic of northern Asia. There is growing evidence for initial human occupation before 700,000 years ago—as early as elsewhere in Asia—and for a very early adaptation to the arctic desert environment. New models of Lower Paleolithic settlement involve expansion and reduction of occupation in response to climatic variation, rather than simple colonization followed by steady occupation. The Middle Paleolithic of northern Asia is better documented, including actual finds of archaicHomo sapiens. The transition to the Upper Paleolithic seems to involve the survival of earlier cultural traits, but the mechanisms and processes are not well understood. Further significant knowledge concerning these periods awaits the development of common methodologies for classification and analysis. 相似文献

This article introduces our themed section on The Left(s) and Nationalism(s), which provides a comparative analysis of the relationship between nationalism and different left-wing parties in Western Europe. It highlights the innovative comparative perspectives offered by this themed section, which not only concerns a series of different geographical cases studies but also involves the ideological plurality of the Left. The larger research question that our contributors address is how different left-wing parties have dealt with the inherent ideological tension between the universality claimed by the Left and the particularism inherent in nationalism, as a doctrine and a principle of political legitimacy. The article stresses three main contributions of our themed section: (1) Western European left-wing parties do engage with the themes of nationalism and nationhood, but they often rely on convenient silence to solve some of the contradictions with their progressive ideology. (2) None of these parties have formulated thick versions of the respective national identities. (3) State-wide left-wing parties have used instrumental conceptions of nationhood to address the challenge of separatist parties, but only with mixed results. 相似文献

In order to carry out strontium (Sr) isotope analysis, glass artefacts from South Asia were sampled with portable laser ablation (pLA), a relatively novel sampling technique that leaves damage invisible to the naked eye. Subsequently, thermal ionization mass spectrometry (TIMS) was used to obtain Sr isotope ratios after sample dissolution and separation. In this study, the goal was twofold: to determine whether the measurements of Sr isotope ratios were impacted by using a portable laser as a sample tool; and to assess the pertinence of using Sr isotope ratios to provenance Indian glass. Despite a deterioration in the precision of the measurement of the Sr isotope ratios for artefacts sampled with pLA compared with the traditional sampling method, the Sr isotope ratios of certain Indian glass are so different that this does not affect their separation but a comparison of data sets obtained using standard methods and pLA might be challenging. 相似文献

We engage geography's longstanding debate on what “counts” as resistance by introducing slow resistance to account for temporal-political strategies against unjust developments, particularly under authoritarian conditions. We draw on over a decade of fieldwork in the Salween River Basin where dams and diversions have been proposed since 1979, including the most recent iteration, the Yuam River water diversion project in Northwest Thailand. We find that resistance by impacted communities and civil society encompasses slow, strategic, and considered actions over time and generations. Such resistance is necessarily protracted to contest developments (re)proposed over decades. By foregrounding the strategic use of time and temporality, we highlight often overlooked actions and strategies of resistance by a diverse range of actors, showing how resistance movements are incremental and interconnected over time, even when “under the radar”. These strategies are key to contesting and (re)shaping the conditions of development in the Basin. 相似文献

We present a new curve of the directional secular variation of the geomagnetic field in Western Europe between 1500 bce and 200 ce . Its computation relies on a Bayesian framework. The fast secular variation during the Late Bronze and Early Iron Ages makes archaeomagnetic dating efficient with a respective precision of 150–200 and 60–100 years during these periods. The Bayesian method also provides posterior date distributions that refine the dating of reference data, especially during the period of the Hallstattian radiocarbon plateau. Archaeomagnetism becomes a valuable alternative to radiocarbon and will help to improve the archaeological chronologies. 相似文献

Based on ethnographic data gathered over 12 months of fieldwork with unmarried women living alone or in flat-shares in different middle class South Delhi localities, this article traces the way shifting gendered norms – often epitomized by growing numbers of single women households – are negotiated within class specific and highly localized contexts of the residential neighborhood. Despite growing economic opportunities for middle class and elite women, cultural anxieties surrounding the notion of ‘delayed’ marriage and women living outside of the familial or marital home persist and obstruct attempts at establishing independent households. Single women experience difficulties finding apartments to rent; have to contend with hostile intrusions from neighbors; or feel obliged to self-monitor their behavior within their neighborhoods. As South Delhi’s liberalised urban landscape has become home to an increasingly globalized, consumerist middle class, disciplinary measures such as curfews, regulations over houseguests and increased surveillance simultaneously indicate a middle class recalibrating its gendered social coordinates by proving its commitment to values of female propriety. While popular discourses draw juxtaposed imaginaries of the ‘modern’ and the ‘traditional’ in their depictions of increasing individualism and a loosening of ‘traditional’ role expectations, this article demonstrates the need to consider the different structural conditions and local inflections in which struggles over women’s agency take place. Looking beyond the supposedly universalizing forces of globalized consumer modernity, the residential neighborhood hereby provides a view into the lived experiences of – at times incongruous – mechanisms at play in societies undergoing social change. 相似文献

ABSTRACTThis paper employs δ13C and δ15N analysis of bone collagen to explore animal management at large Norse settlement sites in the liminal environments of the Scottish North Atlantic Islands. The Norse period was a time of social, cultural and economic change; the need to feed an expanding population and the demand for trade meant that domestic stock were a crucial resource. Our results indicate that rearing animals in these challenging insular environments required careful management. At all sites, the diet and movement of domestic cattle and sheep were highly similar and carefully controlled and, despite many of the analysed settlements lying close to the coast, there was no use of shorefront grazing or fodder resources. In contrast, pig rearing strategies varied across the island groups. In the Western Isles pig diets were diverse, indicative of household or ad hoc management, whilst on Orkney all pigs consumed a more restricted diet based primarily on terrestrial protein. A comparison of red deer with domestic stock on the Western Isles indicates that both groups were exploiting similar grazing niches. 相似文献

Rural youth and urban-based vocational training: gender,space and aspiring to ‘become someone’ 总被引:1,自引:0,他引:1

ABSTRACTThe policy phrase Technical and Vocational Education and Training (TVET) is rapidly gaining ground across Southeast Asia (and beyond). Despite numerous policy reports, little is known about how vocational training and education work as sites of practice. This is especially true for informal household-based apprenticeships and privately organized, commercial classroom-based training. Yet, these latter arrangements are numerous, an integral part of the widespread informal economy, and reflecting the fact that homes have retained their productive character in much of the Global South. Combining a village-based perspective (Laos) with an urban-based perspective (Cambodia), we analyse how these informal and privately organized training spaces are situated in rural youth’s gendered lives and shaped by, but also generative of, aspirations of ‘becoming someone’. In addition, comparing informal apprenticeships with classroom-based training leads us to raise some important questions about the implications of the (global) policy emphasis on the standardization and formalization of TVET. 相似文献
