Occupying the Margins: Labour Integration and Social Exclusion in Artisanal Mining in Tanzania

This article examines the marginal position of artisanal miners in sub‐Saharan Africa, and considers how they are incorporated into mineral sector change in the context of institutional and legal integration. Taking the case of diamond and gold mining in Tanzania, the concept of social exclusion is used to explore the consequences of marginalization on people's access to mineral resources and ability to make a living from artisanal mining. Because existing inequalities and forms of discrimination are ignored by the Tanzanian state, the institutionalization of mineral titles conceals social and power relations that perpetuate highly unequal access to resources. The article highlights the complexity of these processes, and shows that while legal integration can benefit certain wealthier categories of people, who fit into the model of an ‘entrepreneurial small‐scale miner’, for others adverse incorporation contributes to socio‐economic dependence, exploitation and insecurity. For the issue of marginality to be addressed within integration processes, the existence of local forms of organization, institutions and relationships, which underpin inequalities and discrimination, need to be recognized.     

Organic Public Geographies: “Making the Connection”

Abstract: A new field of “public geographies” is taking shape ( Fuller 2008 ) in geography's mainstream journals. While much is “traditional”, with intellectuals disseminating academic research via non‐ academic outlets ( Castree 2006 ; Mitchell 2008 ; Oslender 2007 ), less visible is the “organic” work and its “more involved intellectualizing, pursued through working with area‐based or single‐interest groups, in which the process itself may be the outcome” ( Ward 2006 :499; see Fuller and Askins 2010 ). A number of well‐known projects exist where research has been “done not merely for the people we write about but with them” ( Gregory 2005 :188; see also Cahill 2004 ; Johnston and Pratt 2010 ). However, collaborative writing of academic publications which gives research participants authorial credit is unusual ( mrs kinpainsby 2008 ; although see Sangtin Writers and Nagar 2006 ). This paper is about an organic public geographies project called “Making the connection”. It is written by a diverse collection of (non‐)academic participants who contributed to the project before it had started, as it was undertaken, and/or after it had finished. This is a “messy”, process‐oriented text ( Cook et al. 2007 ) working through the threads (partially) connecting the activities of its main collaborators, including a referee who helped get the paper to publication.     

On the spatial and technological organisation of hafting modifications in the North African Middle Stone Age

Aterian stone tools represent one of the clearest indications of technological regionalisation in the North African Middle Stone Age. Found in association with Homo sapiens skeletal remains and more recently with symbolic material culture, the Aterian is widely thought to reflect modern human identity and cognition. As a lithic industry, the Aterian has been primarily defined by the presence of stemmed or tanged tools, but there has been little quantitative study of the relationship between tangs and other forms of hafting modifications, such as shouldering and basal thinning. Understanding the diversity of these features and their relationships with one another will clarify the organisation and adaptations of North African populations during Marine Isotope Stage 5 (MIS 5, ∼130–70,000 years ago), a critical timespan for modern human dispersal. This paper presents the results of a stepped analysis of fifteen Aterian and other non-Aterian assemblages from the same spatial and temporal bracket in North Africa. Using Correspondence Analyses together with a suite of other statistics, the results indicate that tanging represents a widely applied strategy of hafting a variety of different tools. On the other hand, basal thinning is specifically correlated with lightweight, highly retouched points. The distribution of these features appears to reflect geographical proximity and shared environments, rather than articulating with traditional named industries. This in turn suggests that a continued focus on tangs to differentiate an ‘Aterian’ from other, contemporary North African MSA industries may be obfuscating regional-scale patterns of technological diversity.     

On the Location Quotient Confidence Interval

The location quotient is a useful tool for comparing area characteristics. It has applications in areas such as health care and economics. Individual location quotient standard deviations play an important role in comparing area characteristics. Using the Delta Method, a closed‐form expression is derived for calculating the standard deviation of the individual location quotient. The performance of the proposed method is assessed by simulation. The application of individual location quotient confidence intervals based on the estimated standard deviations is illustrated using health utilization data.
