Some of the most notable and largely endangered archaeological remains from the Lake Chad area consist of the ruins of fired-brick elite constructions connected to the Kanem-Borno Empire (ca. eighth–nineteenth century AD). In the course of the last 200 years, several of the elite structures known west of the lake were destroyed as a consequence of war, later having their fired-bricks looted for constructions elsewhere. One of the largest and most thoroughly plundered of those structures once stood within the walled settlement of Garumele, SW Niger Republic. In the scope of an experimental field study at that location and with a view to future work at related sites, we demonstrate that it is still possible to retrace the ground plans of Kanem-Borno fired-brick structures, even if these have been already completely pillaged. In addition, we present new chronological evidence suggesting that Garumele—as a walled urban settlement—was founded sometime between the mid-fifteenth and mid-seventeenth centuries, but most probably between the late sixteenth to mid-seventeenth centuries AD.  相似文献

In the context of adaptation to climate change and spatial planning, the idea of urban and regional resilience has been attracting increasing attention because it recognizes both the given uncertainty of climate change and the complexity of cities and regions. Even if initial attempts have been made to operationalize the concept of resilience, a gap exists between the intense theoretical discussion and the use of resilience thinking in planning practice. On the basis of a discussion of existing attempts that define resilience principles, the authors derive eight principles for urban and regional resilience: diversity, redundancy, flexibility and adaptability, modularity, interdependency, stabilizing and buffering factors, mobility, as well as planning and foresight. Referring to two exploratory studies—the City and Region of Stockholm (Sweden) and the City and Region of Rostock (Germany)—this article aims to explore whether spatial planning already contributes to these principles and so to build resilience. The analysis shows that spatial planning already contributes to urban and regional resilience. Also, the principles, as suggested here, can be used to operationalize the idea of resilience. Prospectively, such principles may support spatial planning to choose adaptation measures and specific objectives and to contribute to urban and regional resilience.  相似文献

International adoption involves crossing borders; it invokes space and geography as adoptive parents imagine distant countries, as children are moved from one nation to another, and as adoptees and their families return to their countries of origin. The spatiality of belonging and identity – but also of trauma and violence – are central concerns for the people involved and to the operations of their cultural, political, and legal practice. Yet surprisingly, cultural geographers have not yet developed a conceptualization of transnational adoption that theorizes it as a constitutive aspect of geographies of migration, domestic geographies, and geography of childhood. In this issue we seek to set out an agenda for the cultural and political geographies of transnational adoption. We do so by discussing three interrelated themes: the adoption-migration nexus, geographies of relatedness, and the biopolitics of mobility.  相似文献

The use of fire is essential for the preparation of hafting adhesives; both are suggested to be a proxy for distinguishing the technological expertise and complex cognition among Palaeolithic populations. While use of fire has been argued to exist from about 1.0 Ma onwards, evidence for adhesives in the Palaeolithic record is rare and fragmented. In spite of the close link between fire places and adhesives, no study has ever focussed on examining the impact of heat on adhesive deposition and preservation. This paper discusses the results of a combustion experiment that was undertaken to understand the impact of heat exposure on hafting adhesives. The results have significant implications for archaeological interpretations. Deposition in or near a fire proves to severely impact the types of residues that preserve on a stone tool. The vertically transferred heat is responsible for the loss of adhesives but also for the incidental production of adhesives and their deposition on stone tools. It can be hypothesised that the rare survival of adhesives on archaeological stone tools might not only be the result of direct contact with the fire but also the result of degradation due to heat from overlying fireplaces. If we are to improve our understanding of the preservation of adhesives, it is important to unstand the taphonomic processes that affect these adhesives, in particular heat alteration.  相似文献

This study explores how the everyday geographies of city life and families’ access to social networks in the neighbourhood influence families’ school choices. The data consist of thematic interviews with parents of 8–14-year-old children (n?=?170) in three urban areas located in the cities of Paris (France), Milan (Italy) and Espoo (Finland) and are analysed via qualitative content analysis. The findings indicate that the families’ access to local social networks influences the reasoning behind school choice to the local school. The children’s relationships with other children and adults in the neighbourhood are considered important, but additionally, the parents’ networks with other parents in the area, mediated by the school, play their role. School choices as practices should therefore be analysed not merely as choices of an institution, as they comprise various aspects concerning the surrounding neighbourhood as a physical and social space.  相似文献
