At Uan Afuda, and other Early Holocene sites of the Acacus mountains, in the Libyan Sahara, dung layers and plant accumulation are a major, but repeatedly neglected, feature of hunter-gatherer communities. To understand the formation and meaning of such features, a multidimensional analysis has been undertaken, combining micromorphological, palynological, botanical, archaeozoological, and archaeological data. The hypothesis here formulated is twofold: plant accumulations are evidence of anthropic activity aimed at the storage of fodder; and dung layers are related to a forced penning of a ruminant, very likely Barbary sheep (Ammotragus lervia). The exploration of these two features has hinted at the existence of a deep reciprocal relationship, which has been interpreted as the cultural control of wild Barbary sheep, leading to a delayed use of food resources. This behavior may be considered an opportunistic strategy adopted to minimize the effects of lean periods and implicates increasing cultural complexity within Late Acacus Saharan forager societies of the 9th millennium B.P.  相似文献

ABSTRACT

This editorial introduction presents the aims and contents of a special issue devoted to cultural policies in Ibero-America. The issue provides a wide-ranging overview about the subject. In addition to papers focused on the development of cultural policy in specific countries, it also includes articles analyzing particular cultural policies in a transnational perspective, paying attention to their multiple programmatic transferences. It also includes articles centred on the development of cultural diplomacy and institutional networks within this area. In this way, it intends to highlight the commonalities among countries and the relations between them, so offering a new and deeper vision of the development of cultural policies in the Ibero American region. In this introduction we offer some theoretical keys for analyzing this development, in particular the notion of family of nations proposed by Castle (1993) and we evaluate its applicability to the case and beyond.  相似文献

Abstract

Spacelab is the conventional name given to a manned laboratory to be carried onboard NASA's Space Shuttle, which was built in Europe under the aegis of the European Space Agency (ESA). This paper deals with the initiatives undertaken in Europe to establish a utilisation programme for Spacelab, in particular for its first flight, planned as a joint ESA/NASA demonstration mission. Two main factors will be discussed, which prevented ESA from establishing a sizeable Spacelab utilisation effort. Firstly, owing to the cost escalation of the Spacelab development programme and to NASA's charging policy for access to the Shuttle system, which did not foressee any preferential treatment to European users, most ESA member states were reluctant to commit funds in support of a long term experimental programme with the new space facility. Secondly, in a situation characterized by strict budgetary constraints, the established European space science community strongly opposed the inclusion of the new research fields opened up by Spacelab (e.g. life and material sciences in micro‐gravity condition) within the framework of ESA's scientific programme.  相似文献

This article seeks to explain the conditions for the emergence and institutionalization of the cultural paradiplomacy of the city of Barcelona and its local effects. The recognition of the city as an active participant on the international stage is based on its evolution from an industrial to a service economy. Against this backdrop, Barcelona’s city council, in common with many other city authorities operating in the world’s metropolises during the 1980s, initiated its own cultural paradiplomacy as a strategy for attracting capital and promoting local development. This policy became established as part of a new multilevel system of governance. This article analyzes the causes of the institutionalization of this activity from an intergovernmental perspective. It concludes that in the context of economic globalization, the emergence of cities’ cultural paradiplomacy is strongly related to the restructuring of the State and its external administration and to the intensification of the ‘cultural branding’ of cities as a tool for global competition.  相似文献

Recently, a new program of territorial study was launched in the area of Wadi Takarkori (Wadi Takarkori Project, hereafter WTP), located in south-western Libya at the border with Algeria in a strategic position between the Tassili and Acacus Mountains. The core of this program was the excavation of a rock shelter together with the systematic mapping and selected excavations of stone structures in the wadi area, mainly tumuli, a typical Saharan feature.  相似文献

This paper aims to emphasize the importance of imported commensal faunas in archaeological contexts by reporting on the earliest known house sparrows and house mice from the Iberian peninsula. The finds, which date to the Iron Age of a hinterland area of the peninsula, have been identified on the basis of osteomorphological and osteometrical criteria, which are specified in the text in order to demonstrate the reliability of the identification. The temporal and geographical coincidence of these remains in the two sites analysed with those of donkey and, secondarily, chicken remains and faunal remains of littoral origin, lends support to the hypothesis that these animals arrived with the earliest trans-Mediterranean colonizers to the southern shores of the Iberian peninsula and spread involuntarily thereafter as ‘side-products’ of the Phoenician commercial routes throughout the Iberian hinterland.  相似文献
