I Like You,I Like Your Pottery: An Ethnoarchaeological Approach to Ceramic Distribution and Acquisition in Northeastern Ghana

This article deals with the myriad determinants involved in pottery distribution in northeast Ghana, considered from a theoretical perspective that integrates the materiality of vessels and the social, political and historical context where both communities and pottery operate in their daily practice. Hence, we develop a comprehensive research strategy that combines emic and etic views covering the multiple dimensions of pottery life history. In this sense, production units, technical traditions and the characteristics of the redistributive centres, as well as the strategies for pottery acquisition, are studied. Special attention is paid to quite varied aspects such as the physical properties of vessels and their performance characteristics, the reputation of both vessels and potters according to the consumers and the mobility and connectivity patterns found in the study area. On the other hand, interpretations regarding the historical and sociopolitical context of the region are emphasised, as well as the interethnic relationships amongst groups inhabiting the area.     

Earliest Evidence for the Ivory Trade in Southern Africa: Isotopic and ZooMS Analysis of Seventh–Tenth Century <Emphasis Type="SmallCaps">ad</Emphasis> Ivory from KwaZulu-Natal

KwaGandaganda, Ndondondwane and Wosi were major Early Farming Community settlements in what is today the KwaZulu-Natal province of South Africa. These sites have yielded, among other remains, abundant evidence of ivory and ivory working dating to the seventh–tenth centuries ad, pre-dating by approximately 200 years the better-known ivory artefacts from sites in the Limpopo River Valley and surrounding regions. We report the results of carbon, nitrogen and strontium isotope analysis to explore the origins and procurement of this ivory, in combination with Zooarchaeology by Mass Spectrometry (ZooMS) to identify the species of animals from which it was derived. All of the ivory studied using ZooMS was elephant, despite the presence of hippopotamus remains on all three sites. Some ivory was probably obtained from elephant herds that lived close to the sites, in the densely wooded river valleys favoured by both elephants and early farmers. Other material came from savannah environments further afield. Ivory found at these three sites was drawn from different catchments, implying a degree of landscape/resource partitioning even at this early stage. These communities clearly invested substantial effort in obtaining ivory from across the region, which speaks to the importance of this commodity in the economy of the time. We suggest that some ivory items were for local use, but that some may have been intended for more distant markets via Indian Ocean trade.     

Quebec–US Relations: The Big Picture

ABSTRACT

The objective of this article is to propose a periodization of the international policy between Quebec and the United States focusing on two levels of analysis: The first level is interested in public policy instruments such as the opening of delegations, while the second focuses on the paradigm of state action. From these two main criteria, I propose an analysis of five periods. The first period (1867–1960) is characterized by the absence of a structured paradigm and the virtual absence of diplomatic instruments with the exception of a tourism and trade office in New York. The second period (1960–1976) reflects a desire by Quebec to develop a larger presence in the United States with the creation of many instruments, as the public policy paradigm is gradually being built. The third period (1976–1980) is characterized by Quebec sovereignists’ awareness of the importance of the United States. This period is noted for a significant paradigm shift. The fourth period (1980–2001) is marked by the turn toward free trade. The last period (2001 to present) is characterized by the importance of new challenges that extend the public policy paradigm to issues such as security in the 9/11 environment, as well as to energy and environmental issues.     

Sozialindex und <Emphasis Type="Italic">gewichtenregeling</Emphasis>

In Germany and the Netherlands spatial information about the social structure of the inhabitants is used for the coordination of financial and human resources in the local school-system. The aim is to reduce educational inequalities by taking the social context of the schools into account. The article explains two approaches. In North Rhine-Westphalia (Germany) a so called Sozialindex is used to distribute additional teachers to municipalities with difficult social surroundings. The Dutch government uses an instrument to give each pupil a weight (gewichtenregeling) depending on the specific educational background. Combined with an evaluation of the school location an additional budget, if necessary, will be payed.     

Bedeutung kleinräumiger Daten für die Evaluation von Bildungsprojekten

The Junior University, a University for children and youth in the city of Wuppertal, offers science courses that target children and youth from all socioeconomic backgrounds. The first evaluation study done by the University of Wuppertal in 2013 aimed at examining whether the Junior University has achieved this goal. The main challenge of our analysis was to approximate missing individual information on socioeconomic status by using spatial data. Therefore, we georeferenced address information of the Junior University students and linked those results to different characteristics available for about 2800 city blocks in the city of Wuppertal. We found out that indeed the Junior University succeeds in attracting children and youth from all socioeconomic backgrounds. The results show that many of the students live in poor neighborhoods or in neighborhoods with a high share of immigrants.     

Das andere Zuhause

Cities are increasingly addressing high-skilled migrants. Our contribution examines the factors that shape how this group relates to places and why cities provide different conditions for this. We draw on empirical data from an explorative case study with highly qualified migrants in the university city of Münster. First, we look at the place ties at the new place of residence and thereby focus on their local social networks and their sense of belonging. Second, we turn to the place-specific characteristics, in particular the role of “connections” and “urban opportunity structures”. Based on our findings we discuss how urban policy-making may influence the place attachment of this desired group.     

The ‘Sand-Bath’ and Lithic Heat Treatment in the South African Middle Stone Age: Myth or Reality?

When heat treatment of silcrete for stone knapping was first discovered in the South African Middle Stone Age (MSA), the procedure used for it was suggested to be similar to the one used for heat treatment of finer rocks in other parts of the world: slow sand-bath heating. This comparison may have been based on published data from the fields of ethnography, experimentation and archaeology, describing sand-bath like structures and processes. In this review, I discuss whether the available data from these three fields indeed justify the suggestions that sand-bath heating was used in the context of MSA silcrete heat treatment. A careful revaluation of the available data shows that, although sand-bath heating is a widely accepted procedure that is documented in other parts of the world, understanding the earliest known cases of heat treatment in the MSA calls for another technical procedure.     

Human Responses to Climatic Variation in the Namib Desert During the Last 1,000 Years

Radiocarbon dates for camelthorn trees in the Namib Desert reflect marked variation in rainfall during the last 1,000 years. These records and other proxy climate data indicate a loose teleconnection with the southern African climatic record, especially for regionwide episodes of dry conditions resulting from extreme El Niño events. However, archaeological evidence of hunter-gatherer and nomadic pastoralist occupation does not mirror the climate record by indicating that the desert was only inhabited during periods of favourable rainfall. It points instead to a specialized strategy which allowed continuous occupation of the Namib Desert despite extreme fluctuations in rainfall, by combining the use of primary resource areas with opportunistic use of secondary, ephemeral resources in an alternating density-dependent and density-independent dynamic.     

Satellite Remote Sensing of Archaeological Vegetation Signatures in Coastal West Africa

This article discusses how archaeological sites in Sierra Leone, and by extension much of West Africa, can be identified through vegetation patterns (vegetation signatures) detectable in very high-resolution (VHR) multispectral satellite imagery. Settlement sites typically have a differing pattern of vegetation from the surrounding landscape, including concentrations of very large trees with sociocultural and historical significance: cotton (Ceiba pentandra) and baobab (Adansonia digitata). These features are conspicuous elements of the landscape both from the ground and in aerial imagery. Two complementary methods of using VHR multispectral satellite imagery are discussed in this paper: visual interpretation and semi-automated subpixel classification. These techniques are aiding ongoing archaeological survey of the Sierra Leone River Estuary. The impact of recently renewed industrial activity at a site of probable archaeological significance is also assessed through visually interpreted VHR satellite imagery.
