Using instrumental neutron activation analysis (INAA) of prehistoric pottery, daub, and modern clay samples from Valencia, Spain, we tested expectations on changes in raw material use with socio-economic shifts during the Neolithic (ca. 5600–2800 BC). Elemental analysis identified three distinctive clay source groups used by Neolithic potters. Contrary to expectations, a shift in raw material use was identified between the Early and Middle Neolithic despite general similarities in technological practices. In the Late Neolithic, pottery production became more specialized, but potters used the same range of clay sources documented earlier. This study illustrates the utility of INAA for testing hypotheses of prehistoric craft production. 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 Using published works, unpublished reports, and photographic records, we examine the research themes, actors, scholars, and institutions that influenced archaeological research in the country.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.
More than fifty years after the discovery of the first remains from Pozo Moro, new research has begun to question the arrangement, until now agreed upon, of the tower-shaped monument. The recent paper by García Cardiel and Olmos (2021) employs iconography to sketch the possibility that the reliefs and sculptures encountered in said necropolis do not belong to a single monument, but two or more. In this paper we delve into this possibility by studying a fragment of architectural moulding from Pozo Moro, which allows us to conclude the possible existence of a pillar-stele datable between 425–300 BC, when the necropolis was at its floruit. To reach this conclusion special attention is paid to Iberian architectural ornaments, a subject seldom yet studied. 相似文献
Antarctica was the last continent to be discovered in the early nineteenth century. In order to become acquainted with the process of incorporation of Antarctica to the scope of the capitalist system we have focused on particularity: i.e., specific economic and technological and ideological aspects of everyday life in sealer camps spread along the coastline of the South Shetland Islands. Archaeological research in Byers Peninsula–Livingston Island provides an approach to the mechanisms implemented to organize the first resource exploitation in these lands. 相似文献
This paper studies the relevance and nature of shifts in relative prices at the regional level in Spain. Deviations in relative prices tend to be small (at most half a point of inflation annually) but persistent. They are determined by features intrinsic to deep economic integration, in particular, wage mechanisms operating at the national level. This is in stark contrast to evidence at the international level. Therefore, while acknowledging that divergent price evolutions are possible in the European Monetary Union, their nature will be different from those observed among Spanish regions. 相似文献
Women's sport has always been a challenging subject in Muslim countries and Muslim women have had to face various constraints regarding their participation in sport and exercise, which also influence their attitudes to sport. This study aims to explore the attitude of Iranian female university students toward sport by survey method (N?=?1,120) and qualitative interviews (N?=?50). The results indicate that the majority of the participants have negative attitudes to sport, and accordingly they do not practice it. Various macro-, meso- and micro-level factors were found as perceived barriers. From the results it can be concluded that the media as a tool for raising awareness to providing role models and shaping the social values of mainstream society does not take a positive role in order to develop the culture of women's sport, and to change the attitude of female students and their social environments to sport in Iranian society. 相似文献
From a theoretical perspective, it is possible to enhance the innovation of firms and institutions by combining the analytic (scientific) knowledge base of research and development (R&D) institutions with the synthetic (practical) knowledge base of industries. Such combinations of knowledge are also believed to support regional development. One such initiative to bridge knowledge from the R&D sector and industry is the Norwegian Centre for Offshore Wind Energy (NORCOWE). However, as our case study shows, it is hard to bridge knowledge from these two partner groups. We found that this is mainly because of differences in the partners' timelines (long versus short), their attitudes toward knowledge (research based versus experience based), application of the knowledge (knowledge per se versus commercialization), and organizational dimensions (linear/closed process versus interactive/open process). These differences show that the knowledge bases of these two groups may not just be different; they can also be seen as discrepant. We also argue that the NORCOWE initiative is influenced by a “policy push” logic. This implies that the initiative was not properly embedded in the industrial or R&D institutions before being launched, but was instead driven by a political will to promote the development of a new renewable energy source. 相似文献
