Economic Geographies of Future-Making along a Development Corridor: Effects of the Southern Agricultural Growth Corridor of Tanzania (SAGCOT) on agro-industrial Global Value Chains
Full text linkDevelopment corridors are currently spreading all over the Global South and especially over the African continent. Fuelled by the global commodities boom and its culmination in the global food and finance crisis in 2007/08, African development corridors have been popularly heralded as a high road to development. Alluring especially with a rapid transformation of agricultural landscapes, many of them are since seen as territorial tool for rapid agro-industrial modernization and globalization. This thesis analyses and explains the mechanisms, processes, and effects behind the mobilization of the perhaps most prominent corridor in Africa with such agro-industrial focus: Namely, the Southern Agricultural Growth Corridor of Tanzania (SAGCOT). Bringing together literature on future-making and economic geography, the thesis contributes a critical realist account on how a narrow vision of modernization and globalization has underpinned the making of the spatial imaginary SAGCOT. This spatial imaginary emptied the future from its (viable) alternatives and claimed space for its ostensibly friction-free implementation in Tanzania’s Southern Highlands.
Using empirical and mainly qualitative case study work along Tanzania’s agro-industrial value chain, the thesis traces SAGCOT’s materialization and analyses and explains the uneven economic geographies – and frictions – created. Focussing on the supply side of agro-industrial chains, it shows how SAGCOT created the possibility for a fertilizer multinational to integrate Tanzanian farmers into its global production network and explains how this enabled the exertion of unprecedented types of power between “firm and farm”. Focussing on the buying side of agro-industrial chains, the thesis further addresses how the financialization of farmland along the corridor, constituted fragile and eventually rather unsustainable chain linkages between smallholder farmers and large-scale commercial farms. In total, the three thesis articles highlight why a simultaneous making and unmaking of future as well a claim of territorial and networked space was inherent to SAGCOT’s mobilization and explain how this had effect on the agro-industrial value chain. Control over a spatial imaginary such as SAGCOT emerges as a critical resource for shaping and nudging economic geographies in the present. What future becomes privileged and what future becomes marginalized may ultimately have substantial repercussions for who loses out and who benefits when practices of future-making are at play
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
Friendshoring in global production networks: State-orchestrated coupling amid geopolitical uncertainty
No full textIn an era of multiple crises and geopolitical uncertainty, the need to deal with heightened risk drives states to locate strategic global production networks (GPNs) in geopolitically aligned states, a trend known as friendshoring. In this paper, we contribute to the literature on the role of geopolitics in GPNs by exploring why and how states engage in friendshoring. To this end, we distill from the literature three geopolitical imperatives that, in addition to more conventional GPN imperatives, drive strategic coupling dynamics: reducing risk exposure, (de-)weaponizing supply chains, and maintaining extraterritorial influence. States and state-linked institutions respond to these imperatives by actively 'pushing out' new inter- and extra-firm relations in GPNs which often includes previously neglected regions in the global periphery - even when regional assets require substantial transformation. To achieve this, states orchestrate efforts at extraterritorial de-risking, outward-oriented network brokering, and extraterritorial institution-building to actively alter the coupling conditions. By applying our framework to qualitative research on the Chinese soybean GPN in Tanzania and German-led green hydrogen investments in Namibia, we demonstrate how GPN friendshoring relies on both coercion or incentivization orchestrated by the state
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
