The evolution of large technical systems in the Waterberg coalfield of South Africa: from apartheid to democracy
Full text linkA thesis submitted to the Faculty of Humanities, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the Degree of Doctor of Philosophy.
Johannesburg, March 2017.This thesis follows the development of a particular set of large technical systems in South Africa from the late apartheid era into the age of democracy. During apartheid technological prowess, upheld by the network of state corporations or parastatals, bolstered the authoritarian rule of the white minority government in South Africa. The economic and political liberalisation of the late 1980s challenged the power of the parastatals and altered the underlying rationale of infrastructure development. In particular I describe the transformation of Iscor and Eskom, two of the country’s major parastatals, and their activities in the Waterberg coalfields, an isolated region on the country’s north-western border. While Eskom’s activities in the region began in the 1980s they gained public notoriety with the construction of the Medupi power station two decades later. The obstacles that Eskom faced at Medupi represent the main challenge of developing large technological infrastructures in the democratic, post-colonial order, where the fruits of infrastructure development demand to be spread beyond the bounds of an elite minority. But the eventual completion of some power generating units in 2015 at Medupi demonstrates that failure is not inevitable. I argue that this success is due to the fact that the autonomous parastatal network negotiated the political and economic liberalisation of the early 1990 by incorporating the changing socio-political conditions into its operations. The parastatal network retained a momentum, in the sense first described by the historian of technology Thomas Hughes, which was also a product of the “locked-in” nature of investment in the infrastructure project. Because of the large capital investment required for the infrastructure development, proceeding tenaciously against the odds to see the project to completion was cheaper than retreat for those involved.MT201
Apartheid’s Leviathan : Electricity and the Power of Technological Ambivalence
No full textA fascinating study that shows how the intersection of technology and politics has shaped South African history since the 1960s.This book details the development of an interconnected technological system of a coal mine and of the Matimba and Medupi power stations in the Waterberg, a rural region of South Africa near the country’s border with Botswana. South Africa’s state steel manufacturing corporation, Iscor, which has since been privatized, developed a coal mine in the region in the 1970s. This set the stage for the national electricity provider, Eskom, to build coal-fueled power stations in the Waterberg.Faeeza Ballim follows the development of these technological systems from the late 1960s, a period of heightened repression as the apartheid government attempted to realize its vision of racial segregation, to the deeply fraught construction of the Medupi power station in postapartheid South Africa. The Medupi power station was planned toward the end of the first decade of the twenty-first century as a measure to alleviate the country’s electricity shortage, but the continued delay of its completion and the escalation of its costs meant that it failed to realize those ambitions while public frustration and electricity outages grew.By tracing this story, this book highlights the importance of technology to our understanding of South African history. This characterization challenges the idea that the technological state corporations were proxies for the apartheid government and highlights that their activities in the Waterberg did not necessarily accord with the government’s strategic purposes. While a part of the broader national modernization project under apartheid, they also set the stage for worker solidarity and trade union organization in the Waterberg and elsewhere in the country. This book also argues that the state corporations, their technology, and their engineers enjoyed ambivalent relationships with the governments of their time, relationships that can be characterized as both autonomous and immersive. In the era of democracy, while Eskom has been caught up in government corruption—a major scourge to the fortunes of South Africa—it has also retained a degree of organizational autonomy and offered a degree of resistance to those who sought to further corruption.
The examination of the workings of these technological systems, and the state corporations responsible for them, complicates conventional understandings of the transition from the authoritarian rule of apartheid to democratic South Africa, which coincided with the transition from state-led development to neoliberalism. This book is an indispensable case study on the workings of industrial and political power in Africa and beyond.https://ohioopen.library.ohio.edu/oupress/1107/thumbnail.jp
Translating Technology in Africa. Volume 1: Metrics
Full text linkTranslating Technology in Africa brings together authors from different disciplines who engage with Science and Technology Studies (STS) to stimulate curiosity about the diversity of sociotechnical assemblages on the African continent. The contributions provide detailed praxeographic examinations of technologies at work in postcolonial contexts. The series of 5 volumes aims to catalyse the development of a field of research that is still in its infancy in Africa and promises to offer novel insights into past, present, and future challenges and opportunities facing the continent. The first volume, on "Metrics", explores practices of quantification and digitisation. The chapters examine how numbers are aggregated and how the resulting metrics shape new realities. Contributors include Kevin. P. Donovan, Véra Ehrenstein, Jonathan Klaaren, Emma Park, Helen Robertson, René Umlauf and Helen Verra
Privacy, privation, and person:Data, debt, and infrastructured personhood
Full text linkAnthropologists have long examined how debt builds upon and occasions interpersonal relations. The recent rise of digital lending in Kenya suggests the necessarily relational dynamics of digital data as well. Despite promises of borrowing unencumbered by social forces, decisions regarding sums lent, tactics to ensure repayment, and profits, are all secured through discerning the relational social dynamics that undergird everyday life. Drawing on these insights, this chapter examines a notion that we call infrastructured personhood through the case of digital data and debt, foregrounding the tensions between attachment and detachment-among and between persons and infrastructures. These anxieties must be understood in terms distinct from the liberal emphasis on individual privacy, seeing digital debt in the context of local ideas of personhood and ongoing histories of privation. This analysis cuts against much of the literature on neoliberalism which argues that, today, we are witnessing the emergence of novel forms of subjectification as people are moulded to operate as autonomous mini-firms; entrepreneurs of the self guided by the same logic as the corporation. By contrast, we foreground how peoples' social relations and their lifeworlds are not being replaced by forms of autonomy but reconfigured as they are filtered through digital databases, infrastructures, and algorithms.</p
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
