Abstract

Surpassing the national perspective usually adopted, the authors confirmed the existence of a pattern of population distribution common to the whole Iberian Peninsula in the long run. This pattern is clearly associated with geographical factors. These variables seem to have more weight in explaining changes between 1877/78 and 1940 than in the period from 1940 to 2001. The observation of the cross-border region has shown that proximity to the frontier has not generated any distinct pattern of population density on either side of the boundary line. The spatial coherence of the observed phenomena throughout the Peninsula and of its evolution, independent of the border between states, reinforces the importance of geographic factors in their explanation. At the same time, this verification opens up new issues related to the effect of national political and economic policies.  相似文献

The prurient element in the popular notion of the ancient Maya sacrifice of “beautiful virgins” during the first half of the 20th century appears to have made researchers wary of studying women in human sacrifice. Interest in human sacrifice arose in the 1990s along with the formulation of the warfare hypothesis for the collapse of Maya civilization so that models of human sacrifice often assumed that victims were largely male war captives. The present study reports on the detailed examination of all the pelvises in the Midnight Terror Cave skeletal assemblage, using osteological and paleogenomic techniques to shed light on the age and sex composition of sacrificed individuals. Our analysis demonstrates the presence of both males and females ranging from subadult to older adult ages. All four paleogenomic sex determinations on samples from subadults were determined female. Additionally, results indicate females fall into two age categories suggesting that sacrificed women may have served as deity impersonators in rituals dedicated to female deities.  相似文献

Transnational coordination is a key aspiration of activists seeking to mobilize globally, yet the literature pays insufficient attention to the impact of cultural differences on transnational networking. In this article I draw on ethnographic data from three European autonomous social movement encounters in the Global Justice Movement (2002–2004) to demonstrate the impact of culture clashes between activists on transnational networking. I use the concept of habitus to explore how routinized, taken for granted, symbolic systems of meaning that individuals from shared locations have in common shape their interactions in transnational encounters. This conception of culture is underutilized in social movement analysis yet offers important insights into internal movement dynamics. I argue that despite the autonomous commitment to radical openness and plurality, a lack of attention to the empirical reality of place‐based activist subcultures and habitus actually works against the “cosmopolitanism” that many activists and scholars aspire to.  相似文献

The research focuses on Portuguese West Coast tourism resorts and addresses the problem of unfinished estates as territorial liabilities left by the Global Financial Crisis on residential tourism and tourism-driven urbanization. After a significant expansion during the golden age, resorts have suffered drastic consequences under the crisis, financial imbalance and stagnation of the real estate market. This situation brings additional problems to land management and adequate responses have not been provided yet. Focusing on the municipality of Óbidos, this paper aims to describe the territorial changes induced by the development of resorts, criss-crossing a morphological analysis with the understanding of the context of the Global Financial Crisis and the assessment of the regulatory framework.  相似文献

The evolution of littoral palaeoenvironments in the southern Pampas region of Argentina towards the end of the early Holocene and the beginning of the mid Holocene is discussed, and the formation processes of the archaeological site of La Olla are analysed. This site is located in the intertidal zone of the present beach and is remarkably well-preserved. The human occupation at the site has been dated at between 7400 and 6480 yrs BP, and is interpreted as a place for the processing and consumption of the southern fur seal (Arctocephalus australis) and southern sea-lion (Otaria flavescens). It is concluded that biostabilization by microbial mats of the sedimentary structures and archaeological remains that developed and are present on the tidal flat prevented their erosion by wind, turbulence currents and waves. This is what has permitted the exceptional preservation of the site. On the basis of the analyses of one of the sectors of the site it can be concluded that the sedimentary succession of the La Olla site is the result of the coastal environmental changes during the early–mid Holocene in the pre-maximum transgressive episode. During this interval a tidal flat developed on the Pleistocene abrasion platform. Human occupation occurred during the formation of mixohaline marsh, an upper intertidal–lower supratidal zone ecosystem.  相似文献

The main aim of this paper is to test the hypothesis on kinship relations (affinity/marriage vs descent/consanguinity, and matrilocality) expressed in the funerary record of the El Argar Bronze Age society (South-east Iberia, 2200–1550 cal BCE), taking into account the absolute chronological dimension of double adult tombs. A set of 23 double tombs having radiocarbon dates for both skeletons were selected, and radiocarbon calibration and Bayesian probability analysis was conducted. The results support the ‘descent’ hypothesis, since for most of the cases the chronological distance between individuals buried together was larger than two decades. Finally, several guidelines for future research are suggested in order to overcome shortages in current chronological and archaeological data.  相似文献

This article examines the historical processes that shaped the development of archaeological practice in Angola during the Portuguese colonial period and the aftermath of political independence. Using published works, unpublished reports, and photographic records, we examine the research themes, actors, scholars, and institutions that influenced archaeological research in the country. We also used documents and museum collections in Angola and Portugal to create a GIS database of Angola’s archaeological findings. This study highlights the events, personalities, and priorities that motivated earlier investigations, and the geographical distribution of prehistoric sites. We hope this study will be a resource for guiding future archaeological research in Angola.

The demand for salt generated by the dietary and domestic needs of most Greek city-states could be usually fulfilled by local resources given the general abundance of salt along the coasts of the ancient Mediterranean. The extremely rare references to interregional salt trade in literary and documentary sources corroborate this idea. As a bulky commodity with little economic value, salt was too expensive to be transported over long distances and was more conveniently obtainable from local resources. However, the situation was different when large-scale fish processing centers entered into the equation. The production and widespread distribution of processed fish required a steady supply of both fish and salt. Salt only was able to transform fish—which is otherwise extremely perishable—into a durable commodity, easy to store and trade. The strategic importance that salt assumed at these centers transformed its economic significance and made interregional trade both convenient and profitable. Also, it was through the medium of processed fish that the surplus of salt production available in certain regions was redistributed across the Mediterranean and came to play an important, albeit indirect, role in interregional trade.  相似文献

A painted monolith, as important as the Aztec Calendar or the Coyolxauhqui, has been discovered in the ritual Aztec center of Mexico City. It represents Tlaltecuhtli, the bisexual manifestation of the Earth from whom all life comes. Still, pigments, which have lost their conglomerating resins, have to be retained. In this study, the consolidation of ochre pigment on original fragments from the Aztec sculpture is presented. Several compounds were tested as consolidants, on the one hand natural polysaccharides, Funori and Slobber of Nopal exudate, on the other derivatives of cellulose, Methocel® and Klucel®, and also commercial consolidants as KSE 300® and Paraloid B72®. To simulate the ageing of consolidated samples, they were treated in an Accelerated Weathering Tester. Then, both sets of samples, fresh and aged, were characterized structural, morphological and texturally by using X-ray diffraction, electronic microscopy and nitrogen adsorption, respectively. A leaching test was performed on consolidated samples to evaluate the consolidant efficiency.  相似文献
