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

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

The Greek Neolithic, here divided into five phases, is the oldest in Europe. Geographically, it is the closest to the Near East and has thus long been seen as an impoverished derivative of the latter. However, recent research has tended to emphasize the autochthonous nature of Neolithic development in Europe, including Greece. The Greek Neolithic economy, which was based almost entirely on domesticates, and its densely packed, long-lived villages strongly recall the Near East, as do also the early emphasis on fine, decorated, nonculinary pottery and the wealth of figurines. On the other hand, the evolution of stylistic patterns is specifically Greek, although generally related to trends in the Balkans. Originality in the development of the Greek Neolithic is also seen in its latest phase, with apparent decreases, rather than increases, in site density, social differentiation, and, to some extent, long-distance trade. At the same time, however, the dichotomy became much sharper between the rich agricultural plains of northern Greece and the more pastoral(?) regions of the Peloponnese and Cycladic Islands; this presages similar contrasts during the Bronze Age. 相似文献

The chronology of the period is briefly considered in the light of the dendrochronological results which have appeared in recent years. Patterns of settlement history in different parts of the area are then examined, and it is suggested that in some of them the late fourth millennium was a period of population decline which was not reversed until the Early Bronze Age, 1000 years later. Detailed information about specific local occupation patterns is provided by recent work on the circum-Alpine lake villages. Changes in cultural patterns during the period, especially the appearance of the Corded Ware, are discussed and explanations of them reviewed. It is argued that changing patterns of gender relations were a major feature of the period, linked to processes which eventually led to the development of small-scale chiefdoms. The development of copper and bronze metallurgy and its connection to these processes are discussed. 相似文献

Madagascar's culture is a unique fusion of elements drawn from the western, northern, and eastern shores of the Indian Ocean, and its past has fascinated many scholars, yet systematic archaeological research is relatively recent on the island. The oldest traces of visitors are from the first century AD. Coastal settlements, with clear evidence of ties to the western Indian Ocean trading network, were established in several places over the next millennium. Important environmental changes of both plant and animal communities are documented over this period, including the extinctions of almost all large animal species. Urban life in Madagascar began with the establishment of the entrepôt of Mahilaka on the northwest coast of the island in the twelfth century. At about the same time, communities with ties to the trade network were established around the island's coasts. From the fourteenth to the sixteenth century, social hierarchies developed in several regions of the island. During the succeeding two centuries, Madagascar saw the development of state polities. 相似文献

ABSTRACTGeographers interested in how entrepreneurs perceive locational environments have studied their mental maps in several European countries, within the theoretical framework provided by behavioral approach. Such studies have typically employed quantitative techniques, but qualitative studies are relatively new to this line of research. In this article, I examine the mental maps of entrepreneurs in Italy by using a mixture of qualitative and quantitative methods. I present and discuss the qualitative outcomes of this research, focusing in particular on the explanatory location factors and the key influences on the mental maps of entrepreneurs. What emerges is the realization that entrepreneurs are far from being fully rational economic actors, who exploit optimally all information and who are driven only by objective considerations. Rather, their views are also affected by subjective factors, individual’s own insights, commonplaces, stereotypes, and prejudices, particularly with reference to the southern regions of Italy (Mezzogiorno), and of other peripheral areas. 相似文献

ABSTRACTThis article argues that some of the contemporary attention given to sustaining habitation of regions and communities beyond capacity and prospects of economic growth can be understood by introducing the concept of ‘vicarious habitation’. By this term is understood ‘the notion of rural habitation performed by an active minority but on behalf of a much larger number, who (implicitly at least) not only understand, but, quite clearly, approve of what the minority is doing’. In many late modern societies, a substantial portion of the population seems willing to pay symbolically and politically to let a minority act on their behalf as caretakers of rural peripheries left behind by structural transformations. Signs of vicarious habitation occur that may vary in form and importance from country to country. Empirically, the argument is substantiated by Norwegian examples. 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
