Freshwater bivalve shells are frequently identified in faunal assemblages from Neo-Eneolithic tell settlements along the Danube River valley in South-East Romania (5th millennium BC). Up until now, significant accumulations of freshwater bivalve shells have been identified only in household refuse areas of the settlements, where they form consistent shell layers. The origin and formation of such shell accumulations and, more generally, the role of bivalves in the animal economy of the prehistoric populations that inhabited the settlements, are poorly understood. Two freshwater bivalve shell accumulations were studied in household refuse areas of Eneolithic tell settlements, one at Bordu?ani-Popin? and the other at Hâr?ova tell. The occurrence of similar accumulations in the two settlements indicates generalized practices between the two communities. This first study of such accumulations addresses the relationship between bivalves and other animal species used in alimentation by the two Eneolithic communities, as well as the relationships between these communities, their environment, and the evolution of the settlements. Bivalves were harvested in the close vicinity of the settlements and large quantities were obtained only towards the end of the summer season. During this season there is an inverse relationship between high water levels in the river and the availability of bivalves for harvesting. Bivalves played an important role in the alimentation of the prehistoric populations – at Hâr?ova tell their contribution to alimentation in terms of energetic yield surpasses that of fish, at least for the short period of time represented by the stratigraphic sequence analysed. Bivalve shells were used, along with other types of household refuse, in construction techniques aimed at limiting soil humidity in the settlements and inside the dwellings.  相似文献

Cheia (early 5th millennium cal BC) is a prehistoric village in the Dobrodgea province in Romania. Its occupation is attributed to the Early Eneolithic period or Hamangia III phase. The exploitation of animal resources is heavily dominated by husbandry. Although cattle are dominant, they were complemented by caprines, mainly sheep, exploited for tender meat (as highlighted by a 6–12 months age class peak in the mortality profile). Sheep reproduction patterns were investigated through stable isotope analyses in order to characterize the annual rhythms of slaughtering for tender meat acquisition while informing a more general picture on sheep demographical management and animal husbandry at the settlement. Results from δ18O analysis on second and third molar enamel were modeled and compared with modern reference populations. Sheep births took place over less than four months, from late winter to early summer. From this it could be concluded that tender meat could be provided most of the year, excepted over short period in early summer. Finally, comparison of datasets obtained on the M2 and M3 suggests that the M2 presents a more accurate representation of birth seasonality due to lower inter-individual variability in the chronology of tooth growth.  相似文献

The European Union (EU) has been continuously rethinking its global position amidst emerging economic and geopolitical challenges and attempting to formulate strategies to increase its competitiveness. However, its long-standing policy implementation deficit is also recognized for its grand strategies, including the initially ambitious Lisbon Strategy. Is Europe 2020 set to fail as well? In this paper, we are arguing that strategic steering is essentially a discursive practice influenced by both semiotic and extra-semiotic factors. Hence, success or failure of a strategy essentially depends on ability to steer the discourse. Niklas Luhmann's social systems theory offers a theoretical framework against which limitations and potentials of strategic steering at the EU level can be analysed. While high levels of rationality and reflection capacities can improve strategic steering, it is limited by the increasing complexity. Recognizing limitations of direct and centralized interventions, we look for analytical and strategic solutions in sophisticated mechanisms of contextual steering: variation, selection and retention of strategic discourses. These mechanisms are integral to the “cultural political economy” approach. In the final part of the paper, we show how cultural political economy can explain the implementation shortcomings of the EU strategies.  相似文献

This article is concerned with the Eneolithic period in southeastern Europe, which corresponds to a phase of increasing social complexity. We demonstrate that the development of a new type of settlement, the tell site, which in southeastern Romania fully began with the Gumelni?a culture, was accompanied by changes in the meat component of the diet. The 39 available faunal spectra are processed by correspondence analyses; this shows that the homogeneity that characterized the previous cultures (Hamangia and Boian) was followed by a greater diversity in animal exploitation systems in the Gumelni?a culture. The main change is the important role that large game played for some Gumelni?a communities (the favored species varied). However, variability existed within the domestic species as well. This may result from the interaction between several possible factors (e.g. new husbandry techniques, complex socio-economic relations between the sites, a great social value given to wild mammals). This diversity contrasts with the homogeneity of the pastoral practices developed for sheep (and, to a lesser extent, for cattle) at the Gumelni?a tell sites (reliable kill-off patterns were established for five sites). We also show that sheep exploitation was specialized. Given that this kind of specialized exploitation became the norm from the Gumelni?a period, we propose that the appearance of homogeneous and specialized practices for sheep is linked to the development of tell sites. More generally, certain standardization in pastoral practices during the Gumelni?a period is possible. For three tell sites, it is likely that the youngest sheep and goats died mainly elsewhere; we suggest that these settlements were parts of larger pastoral systems, on a local or regional scale, and that places or sites with complementary functions existed.  相似文献

Sub-national economic policies increasingly use labor market areas (LMAs) rather than administrative areas for analysis and implementation. How a set of LMAs was defined influences the results of such analyses, and so accurate policy delivery needs appropriately defined LMAs. Multinational bodies need comparable LMA definitions in many countries, calling for a definition method that is transferable across national boundaries. This article applies quantitative metrics to evaluate LMAs defined in three contrasting countries by three methods that represent the main methodological approaches. The deductive approach—based on a center and hinterland—is too inflexible to deal with differing geographical circumstances and cannot cope with statistical zones that are very small, or do not respect settlement structure. The alternative inductive methods tested define appropriate LMAs in each country, with the newer method performing slightly better in statistical terms. The article also exemplifies the usefulness of the metrics for comparisons of alternative regionalizations.  相似文献

Lead isotopes combined with trace element data represent a powerful tool for non‐ferrous metal provenance studies. Nevertheless, unconsidered geological factors and archaeological data, as well as ignored analytical procedures, may substantially modify the interpretation of the isotopic and trace element signature obtained as a potential ore candidate. Three archaeological examples, accompanied by high‐resolution lead isotopic measurements (MC–ICP–MS), are presented here to discuss the above‐mentioned criticisms and to propose some solutions. The first example deals with prehistoric/historical gold/silver‐mining activity from Romania (the Baia Bor?a and Ro?ia Montan? ore deposits). The second one regards the lead/silver metallurgical activity from the Mont‐Lozère massif (France) during medieval times. The third example focuses on the comparison between two batches of lead isotope data gathered on Roman lead ingots from Saintes‐Maries‐de‐la‐Mer, using different SRM 981 Pb values.  相似文献

ABSTRACT

Beirut and Sarajevo share a long Ottoman past followed by urban expansion under the protectorate of further imperial rule – of the French and Habsburg Empires, respectively, as well as a recent experience of urban warfare, segregation, and post-war reconstruction. This article examines how the architectural heritage of empires in the two cities has been transformed, reimagined and mobilized through urban post-war reconstruction by a number of actors: local authorities and politicians, architects, international organizations and investors. Discussing the tensions between the memory of empire and contemporary nation-building processes, the essay argues that the politics of memory and amnesia surrounding the recent wars shape and reconfigure the memory and heritage of empire. Moreover, it reflects how the reshaping of urban space acts both as an arena and as an enhancer of the politics and practices of memory and amnesia.  相似文献
