Gold Mining in the Sahara-Sahel: The Political Geography of State-making and Unmaking
No full textIn the Sahara-Sahel, artisanal gold mining is booming. Fragile Sahelian states arguably provide a most likely case for the ‘resource conflict’ theory to hold, yet ‘resource capture’ can also underpin informal governance schemes through which the co-optation of non-state actors ushers in (hybrid) state-building. While the diversity of empirical cases lends credibility to both theories, the dialectic of proximity and distance–both social and spatial–helps make sense of the different modalities of artisanal gold mining governance in the region. In the Sahelian core of regional states, artisanal gold mining has supported regime empowerment; in the Sahara, it has helped assuage pre-existing tensions; in the Tibesti, it has led to militarisation and conflict
The Bioeconomy of Sahel Borders: Informal Practices of Revenue and Data Extraction
No full textAs recent work in border studies has argued, EU-border externalisation is often achieved by exporting technocratic management templates and advanced surveillance technologies, prompting scholars to adopt the lens of biopolitics in studying borderwork. Outside of Europe, however, the paucity of resources and vastness of spaces mean that indigenous forms of agency continue to be a key factor of border governance. Focusing on everyday practices illuminated by ethnographic fieldwork, this article investigates EU border externalisation’s encounter with the Sahelian context. It argues that state and non-state actors form, deform and perform borders by extracting and capturing the material (economic) and immaterial (cognitive) resources that pass through liminal spaces. These dynamics shape a biopolitical economy of border control in which features of exceptionality, sovereignty and politics seem less compelling that those pertaining to the sphere of ordinary, hybridity and economy
Explaining the Rise of Jihadism in Africa: The Crucial Case of the Islamic State of the Greater Sahara
No full textWhile jihadism appears to be on the rise in Africa, the explanations of violent extremist groups’ capacity to foment jihadi insurgencies and mobilize recruits remain poorly understood. Recent studies have challenged the assumption that the rise of jihadism in Africa is the result of poor governance in areas of limited state reach, highlighting instead the significance of the (perception of) abuses perpetrated by state authorities. Looking at collective action and its structural determinants, it is rather state action—and not the lack thereof—that best explains the capacity of mobilization of jihadi insurgencies in African borderlands. In order to test this theory in a least-likely case, the article explores the genealogy and evolution of the Islamic State in the Greater Sahara (ISGS), mobilizing extensive qualitative evidence. Borrowing the analytical framework from civil war studies, it argues that the contentious political dynamics observed in Niger’s borderlands amount to a case of symmetric non-conventional warfare, where abuses perpetrated by state proxies trigger an escalation of homegrown terrorism. It therefore supplies a further specification of the theories investigating the complex interplay between the processes of jihadi mobilization/rebel governance and the practices of counter-terrorism in weak states
Drug Smuggling and the Stability of Fragile States. The Diverging Trajectories of Mali and Niger
No full textWhat is the impact of smuggling on political ordering and stability in fragile states? We investigate how transnational drug smuggling networks affect protection and extraction dynamics, and drive divergent political stability trajectories in fragile countries that otherwise exhibit structural similiarities–i.e. Mali and Niger. Building on ethnographic evidence, we explore the hypothesis that distinctive peace- and state-building strategies result in different degrees of resilience vis-à-vis potentially destabilising factors. To explain variation in political stability we introduce the concept of ‘hybrid state-sponsored protection racket’, in which non-state armed actors are coopted in a protection assemblage under the tutelage of the state
The data that we do (not) have: studying drug trafficking and organised crime in Africa
Full text linkAn increasing amount of reports highlights the growing salience of drug trafficking in Africa. Yet the evidence-base for this claim remains problematic. Stemming from a critical approach to social sciences’ epistemology, the paper explores how drug trafficking data are framed, produced and shared. Building on an extensive literature review and key interviews, it provides an in-depth analysis of both the main open source drug trafficking metrics (at UN, US and EU level), and the inner working of anti-drug trafficking agencies in key African countries, i.e. Nigeria, Senegal and Mali. The analysis shows that politicised framings, practical challenges and methodological inconsistencies affect drug trafficking knowledge production, especially in Africa. The paper therefore suggests to treat drug trafficking data – both quantitative and qualitative ‘evidence’ – not as proxies that would reveal ‘the reality’ of criminal under- and over-worlds ‘out there’, but performances whose appearance and disappearance is part and parcel of the mechanics of state (un)making. Anchoring the interpretation of drug trafficking data to the dynamics of protection and extraction characterising parallel modes of governance in the post-colonial world leads to the acknowledgement that the absence of reliable data is not a mere knowledge gap, but a datum in itself that calls for interpretation and investigation
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
