In the second half of the 19th century, the area known as Lezíria, in Portugal, started to use portable steam and traction engines in agricultural production. Out of more than a hundred original examples, all of them manufactured in England, little more than a dozen survive today, with different levels of preservation. This article studies these for the first time through an archaeological perspective, identifying their use and importance in different agricultural activities in the production of goods such as olive oil.  相似文献

ABSTRACT

This paper examines the contribution of microscopic multi-proxy approaches to the study of early husbandry practices and animal diet by integrated micromorphological, phytolith, and calcitic dung spherulite analyses of midden deposits at the three neighbouring Neolithic sites of Boncuklu (9th–8th millennium cal BC), P?narba?? (7th millennium cal BC) and Çatalhöyük (8th–6th millennium cal BC) in the Konya Plain, Central Turkey.

The results reveal considerable chronological and contextual variation in human-animal inter-relations in open areas between different communities and sites. At Boncuklu, middens display well-defined areas where phytoliths and substantial accumulations of omnivore faecal matter low in spherulite content have been identified. By contrast, open spaces at the Late Neolithic campsite of P?narba?? comprise large concentrations of herbivore dung material associated with neonatal ovicaprine remains from spring birthing. Here, the deposits represent repeated dung-burning events, and include high concentrations of dung spherulites and phytoliths from wild grasses, and leaves and culms of reeds that, we suggest here, derive from fodder and fuel sources. Late middens at Çatalhöyük are characterised by thick sequences derived from multiple fuel burning events and rich in ashes, charred plants, articulated phytoliths – mainly from the husk of cereals, as well as the leaves and stems of reeds and sedges – and omnivore/ruminant coprolites, the abundance of the latter declining markedly in the latest levels of occupation.

The application of this integrated microscopic approach to open areas has contributed to unravelling the complexity of formation processes at these sites, providing new insights into herding practices, diet, and the ecological diversity of Neolithic communities in Central Anatolia.  相似文献

This paper is the first updated review of the scope, depth and problems related to the current radiocarbon chronology of the late prehistory of southern Iberia. The aim is twofold. First, it critically analyses the quantity and quality of radiocarbon dates used to interpret the diverse trajectories of western Mediterranean societies throughout more than four millennia. Secondly, it reviews a set of three different and prominent archaeological phenomena from an inter‐regional comparative perspective: primary and secondary burial practices, domestic stone architecture and ditched enclosures. Our long‐term, geographically wide‐ranging approach locates similarities while highlighting the effects of local and historical conditions in certain divergent circumstances.  相似文献

The participation of interpreters as linguistic and cultural mediators is considered essential to the success of military operations in a foreign country. This study examines the situation of two categories of civilian interpreters who worked for the Spanish armed forces in Afghanistan: interpreters recruited in Spain and interpreters recruited in Afghanistan. The distinct positionalities of these groups of interpreters emerge as a recurring theme in the interviews carried out as part of this research. The findings indicate that the interpreter’s positionality impacted the interpreter’s agency, the trust placed in him or her by the armed forces, and exposure to danger. In highlighting interpreters’ active participation in the communicative situation, this paper increases understanding of the positionality of interpreters in war zones.  相似文献

ABSTRACT

In this paper, we focus on the question of how particular types of regions react to economic shocks. Drawing on a case study of Czech microregions, we aim to determine if the old industrial regions differ significantly from other types of regions (metropolitan, urban, rural) in (post)crisis economic development. Two aspects of regional resilience (measured by unemployment growth) were considered: recession and recovery. We focused on the comparison of two subsequent recessionary shocks: the 2008–2010 global recession and the 2012–2013 austerity crisis. Metropolitan regions showed relatively stable economic development. Old industrial regions were more resilient than expected. Rural regions exhibited highly diverse reactions: lower resistance was characteristic for regions specialized (mostly) in automotive and some labour-intensive industries. The first wave of recession increased unemployment mostly in (rural) regions dependent on export-oriented manufacturing, the second wave especially hit larger cities with metropolitan functions. Regions that experienced a sharp unemployment increase in the first recession were generally more resistant in the second wave. All types of regions were internally highly diverse in their reactions to economic crises, which points to the importance of micro-regional variations of economic resilience, the performance of individual local firms and subsidiaries, and extra-regional factors of regional development.  相似文献
