This paper reviews Rwandan ceramic typologies and integrates these with recent regional ones through the consideration of four new ceramic assemblages dating to three distinct phases across the past 2,000 years. In addition to providing a synthesis of ceramic approaches as a research resource, it also suggests that ceramics previously termed type C might now better be understood as a transitional form of Urewe. In so doing, it both describes how previous accounts of Rwanda's archaeological ceramics reproduced a contested ethno-racial colonial construction of Rwandan society and suggests the replacement of these with non-ethno-racial explanations of material culture change proposed elsewhere for comparable circumstances in Great Lakes Africa. Finally, as the government seeks to reintroduce secondary school history teaching using archaeological narratives, it discusses the contemporary political significance of this and other research in post-genocide Rwanda, arguing that archaeology, whether framed in technical language or not, has contemporary political reference.  相似文献

Although no paintings are associated with archaeological contexts before the end of the Middle Stone Age, hundreds of ochre pieces were discovered on numerous southern African sites suggesting a lasting tradition of ochre use. The variability and the significance of ochre exploitation remain however poorly documented. The MSA site of Diepkloof Rock Shelter (Western Cape Province, South Africa) offers an ideal opportunity to discuss questions of ochre procurement, processing, and use over a long sequence. This study develops an original methodology based on observations on one hand, and SEM-EDS, XRD and Raman spectrometry analyses on the other hand. By comparing raw materials with our geological database, we show that some iron-rich raw materials were collected more than 20 km from the site. Such long-distance procurement combined with other elements of the overall context suggests a planning of procurement. One main chaîne opératoire based on grinding was identified at Diepkloof. In comparison with other South African sites, we observed no evidence for use as loading agent in adhesives. We conclude that ochre use may follow regional cultural patterns.  相似文献

The brissid echinoid Schizobrissus insignis (Duncan &; Sladen, 1883) is described from the Fulra Limestone (late middle Eocene), in Kachchh, India. Formerly assigned to Peripneustes or to Meoma it is shown that the species possesses a complete subanal fasciole throughout ontogeny, a characteristic feature of Schizobrissus. Eocene species of Schizobrissus and Meoma show several morphological similarities, but diverged during the late Paleogene and early Neogene.  相似文献

Regional policies across Europe aim at stimulating regional development in non-core regions through fostering entrepreneurship. However, the policies applied in non-core regions and the concepts of entrepreneurship these policies are based on differ. Therefore, the goal of this review is to identify different understandings of entrepreneurship and their role for regional development processes in European non-core regions. To this end, empirical studies investigating entrepreneurship in European non-core regions from 1999 to 2011 were analysed. The results of the analysis are presented along three drivers and outcomes of entrepreneurship identified inductively from the literature: innovation, social capital and institutional change. We made out seven different types of entrepreneurship in European non-core regions. These seven types of entrepreneurship comprise particular mechanisms through which they stimulate regional development. Further research should study the interplay between these different mechanisms of regional development in non-core regions which may induce a more territorial approach to understand entrepreneurship in non-core regions across Europe.  相似文献

Heritage is invoked for post-conflict development by international organisations, governments, and sub-national groups to provide emotional and cultural, including economic, healing for individuals and societies. However, academic critiques of healing-heritage typically cite the failure of heritage to heal, either because it cannot, or because it is managed incorrectly. Thus, an anomalous situation exists between expectations and critiques, which this study describes and explores through international policies and national and sub-national post-conflict healing-heritage initiatives from Rwanda and Uganda. Drawing on concepts of heritage as a cultural process, cultural trauma, and symbolic healing, this study proposes that heritage is neither an essentially positive nor negative post-conflict development strategy to select or avoid respectively. Instead, heritage is better understood as a common element of post-conflict renewal, which becomes intensified as the past is aggressively negotiated to provide healing related to conflict traumas. By moving beyond the ‘does heritage heal or hurt?’ distraction the meaning and function of heritage in post-conflict contexts as a common element of post-conflict healing complexes is elucidated. The implication for those who wish to manage post-conflict development through heritage is that they are just the latest in a long history of symbolic healers, from whom they have a lot to learn.  相似文献
