The remains of 20 individuals buried in three different pantheons, putatively pertaining to the medieval Royal House of Aragon, were analysed for their isotope (14C, 13C and 15N) measurements. The radiocarbon dates and stable isotope data contributed to identifying individual members and, combined with additional osteological and taphonomic information, as well as documentary evidence, provided a fuller picture of the diets and life histories of particular people. This group comprised the first members of a royal dynasty that ruled the Kingdom of Aragon before the Spanish Crown was established, and that played a significant role in the reconquest of the Iberian Peninsula from Muslim control, this being of paramount importance in the Spanish and European history.  相似文献

This article highlights the role of food as an essential tool for immigrant Mapuche families to reinforce their ethnic identity and pass it on to the younger generations in Santiago de Chile. Food and food-related practices were a topic that many Mapuche referred to when they were invited to talk about their culture and life in Santiago; this simultaneously revealed their relation to ‘others’ (Chileans) and their connectedness to their ancestral lands in the Araucania region in the south. Staying attuned and connected to the south through Mapuche food strengthens feelings of cultural continuity and belonging, such that Mapuche ethnic identity does not surrender to the city, but rather is re-created in a new environment.  相似文献

The p‐regions is a mixed integer programming (MIP) model for the exhaustive clustering of a set of n geographic areas into p spatially contiguous regions while minimizing measures of intraregional heterogeneity. This is an NP‐hard problem that requires a constant research of strategies to increase the size of instances that can be solved using exact optimization techniques. In this article, we explore the benefits of an iterative process that begins by solving the relaxed version of the p‐regions that removes the constraints that guarantee the spatial contiguity of the regions. Then, additional constraints are incorporated iteratively to solve spatial discontinuities in the regions. In particular we explore the relationship between the level of spatial autocorrelation of the aggregation variable and the benefits obtained from this iterative process. The results show that high levels of spatial autocorrelation reduce computational times because the spatial patterns tend to create spatially contiguous regions. However, we found that the greatest benefits are obtained in two situations: (1) when ; and (2) when the parameter p is close to the number of clusters in the spatial pattern of the aggregation variable.  相似文献

This paper studies the vertical and horizontal interactions between federal and regional governments in terms of public deficits. Recent studies commonly restraint budget slippages to the incentives created by the institutional arrangements within a country. Alternatively, we estimate here a fiscal reaction function for the Spanish regions over the period 1995–2010, paying special attention to the impact of the federal fiscal stance on regional fiscal imbalances. Our results indicate that higher public deficits for the central government encourage larger fiscal imbalances at the regional level. This vertical interaction is interpreted in the context of yardstick competition models. We also find a significant impact from fiscal decisions taken by governments at the same decision‐making tier in a specific region.  相似文献

The question of the Anthropocene has gained increased notoriety among archaeologists recently. Precisely because of that, it is in need of thorough critique. The aim of this article is not to rule out the concept of Anthropocene, but to point out some of its problems: the relationship of Anthropocenic discourses with the emergence of an all-embracing biopolitical science; the inadequacies of the term, which blames all humans equally for a specific effect of modernity and capitalism; its failure to accept a diversity of origins (but also the problem of accepting overly deep origins), and the shortcomings of adopting a geological framework for archaeology. I thus suggest that the discipline has to define its own eras – also for the contemporary period – and that the Age of Destruction could be an apt archaeological counterpart for the Anthropocene. One of the benefits of outlining an archaeological era is that it brings modernity and capitalism back to the fore, and with them issues of power and conflict that have been largely lost in recent post-anthropocentric debates.  相似文献

It is a truism nowadays to say that an archaeological site is embedded in extensive networks of relations. Connectivity has played a role in archaeological thinking for a considerable amount of time, and the adoption by archaeologists of both theoretical and methodological frameworks centring connectivity has become widespread. One such example is network analysis, which has seen a significant surge in interest within the field over the past two decades. Archaeological network analysis is far from a mature science, however, and the character of the archaeological record tends to yield networks with richly contextualised nodes connected by ties that, in stark contrast, are often based on very limited evidence for connectivity. Furthermore, archaeological networks are often accompanied by limited discussion about the implications for a connection between two sites interpreted through a commonality in material culture. In particular, the use of historical records to contextualise the interactions between sites remains somewhat uncommon. This paper takes an archaeo-historical network perspective by characterising land-use practices in early modern Iceland by mapping property records describing relations of ownership, resource claims and social obligations alongside comprehensive field archaeological surveys as extensive networks of interdependence between the known farmstead sites occupied at the time. This approach shows that these vibrant networks, documented both spatially and historically, regularly show signs of emergent properties. As these intersite relations begin to exert their own agency, the networks are cut, and the network lines begin to bundle up in knots and entanglements. The study, therefore, does not aim to quantify the presented networks using formal network analysis, but to use the networks as a starting point to investigate the properties that emerge as people aim to enact and materialise networks of property rights, resource claims and exchange.  相似文献

Vento, B. &; Prámparo, M. B., January 2018. Angiosperm association from the Río Turbio Formation (Eocene–?Oligocene), Santa Cruz, Argentina: Revision of Hünicken’s (1955 Hünicken, M., 1955. Depósitos neocretácicos y terciarios del extremo S.S.W. de Santa Cruz: Cuenca Carbonífera de Río Turbio. Revista del Instituto Nacional de Investigacion de las Ciencias Naturales 4, 1161. (in Spanish) [Google Scholar]) fossil leaves collection, Alcheringa 42, 125–153. ISSN 0311-5518.

The Río Turbio Formation (Eocene–?Oligocene) is of particular paleobotanical interest owing to its combination of high fossil plant diversity associated with the coexistence of warm-temperate and cool-temperate components. As the first suite of fossils related to a documented stratigraphic section, Hünicken’s fossil plant collection is one of the most important from the Paleogene of South America. A total of 34 angiosperm species from the collection were reviewed and taxonomically updated, with Nothofagus as the dominant genus. The taxa identified indicate a warm and humid climate with the development of some elements of a cool-temperate climate marked by a transitional climate change to cooler conditions. The comparison of angiosperms from different paleofloras from the southernmost of South America confirms that the assemblage of Río Turbio Formation was similar to that of the Río Pichileufú area, both from Patagonia, Argentina.
