Clouded data: privacy and the promise of encryption
No full textPersonal data is highly vulnerable to security exploits, spurring moves to lock it down through encryption, to cryptographically ‘cloud’ it. But personal data is also highly valuable to corporations and states, triggering moves to unlock its insights by relocating it in the cloud. We characterise this twinned condition as ‘clouded data’. Clouded data constructs a political and technological notion of privacy that operates through the intersection of corporate power, computational resources and the ability to obfuscate, gain insights from and valorise a dependency between public and private. First, we survey prominent clouded data approaches (blockchain, multiparty computation, differential privacy, and homomorphic encryption), suggesting their particular affordances produce distinctive versions of privacy. Next, we perform two notional code-based experiments using synthetic datasets. In the field of health, we submit a patient’s blood pressure to a notional cloud-based diagnostics service; in education, we construct a student survey that enables aggregate reporting without individual identification. We argue that these technical affordances legitimate new political claims to capture and commodify personal data. The final section broadens the discussion to consider the political force of clouded data and its reconstitution of traditional notions such as the public and the private
Red Pilled - The Allure of Digital Hate
Get PDFHate is being reinvented. Over the last two decades, online platforms have been used to repackage racist, sexist and xenophobic ideologies into new sociotechnical forms. Digital hate is ancient but novel, deploying the Internet to boost its allure and broaden its appeal. To understand the logic of hate, the author investigates four objects: 8chan, the cesspool of the Internet, QAnon, the popular meta-conspiracy, Parler, a social media site, and Gab, the "platform for the people." Drawing together powerful human stories with insights from media studies, psychology, political science, and race and cultural studies, he portrays how digital hate infiltrates hearts and minds
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
Archive As Cyborg: Imagining Archaeologies of the Future
No full textContemporary art has borrowed from the archive’s organisational structure, critiqued its hegemonic influence on the construction of cultural narratives, and reconfigured its contents to reimagine the past. However, ‘archival art practice’ has not yet extensively explored issues of Big Data, or examined its effects. Big Data promises to help us better understand the world and build models that try to predict the future. Data collecting devices are inserting their sensors into our lives on an increasingly intimate scale, permeating boundaries between human and computer, the analogue and the digital, reality and fiction. How might practice based research, combined with an investigative approach, reimagine the political spaces and power structures that influence the production, organisation, and propagation of knowledge?
This research poses a tentative response to the preceding question through theoretical and practical lines of enquiry, in order to explore relationships between emerging technologies, myth-building, and geopolitics. It takes the academic paper, “Capitalisation of the Future,” as a point of departure. The paper was written by Anton Vaino, Kremlin’s Chief of Staff, though both its origins and validity are disputed. In it, Vaino’s alleged invention, the Nooscope, is described as a spatial scanning device, formed from a network of data collecting sensors and satellites designed to intercept interactions between humans and electronic devices. The wording of the paper has been ridiculed as unscientific and mystical. Throughout Russian history, distinctions between the spheres of politics and religion, science and mysticism, are not as sharp as in the West. This thesis takes the Nooscope as a vessel and experimental playground for the exploration of these ideas.
The thesis articulates a theoretical framework, contextualises the research-based art practice, and presents a case study of the ways in which discourses around planetary-scale Big Data projects, such as the Nooscope, are presented. The artwork provoked by the Nooscope has been designed to be viewed in parallel to the ideas discussed in the written thesis
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
