No full textThis text explores the impact of facial recognition technology (FRT) on policing, surveillance, and human rights. It reveals how FRT reshapes police-citizen interactions and introduces frameworks to address its complex effects
Bulk Surveillance in the Digital Age: Rethinking the Human Rights Law Approach to Bulk Monitoring of Communications Data
Full text linkThe digital age has brought new possibilities and potency to state surveillance activities. Significant has been the advent of bulk communications data monitoring, which involves the large-scale collection, retention, and subsequent analysis of communications data. The scale and invasiveness of these techniques generate key questions regarding their ‘necessity’ from a human rights law perspective and they are the subject of ongoing human rights-based litigation. This article examines bulk communications data surveillance through a human rights law lens, undertaking critical examination of both the potential utility of bulk communications surveillance and – drawing on social science analysis – the potential human rights-related harm. It argues that utility and harm calculations can conceal the complex nature of contemporary digital surveillance practices, rendering current approaches to the ‘necessity’ test problematic. This paper argues: that the distinction between content and communications data be removed, that analysis of surveillance-related harm must extend beyond privacy implications and incorporate society-wide effects, and that a more nuanced approach to bulk communications data be developed. Suggestions are provided as to how the ‘necessity’ of bulk surveillance measures may be evaluated, with an emphasis on understanding the type of activity that may qualify as ‘serious crime’
‘I started seeing shadows everywhere’: the diverse chilling effects of surveillance in Zimbabwe
No full textRecent years have witnessed growing ubiquity and potency of state surveillance measures with heightened implications for human rights and social justice. While impacts of surveillance are routinely framed through ‘privacy’ narratives, emphasising ‘chilling effects’ surfaces a more complex range of harms and rights implications for those who are, or believe they are, subjected to surveillance. Although first emphasised during the McCarthy era, surveillance ‘chilling effects’ remain under-researched, particularly in Africa. Drawing on rare interview data from participants subjected to state-sponsored surveillance in Zimbabwe, the paper reveals complex assemblages of state and non-state actors involved in diverse and expansive hybrid online–offline monitoring. While scholarship has recently emphasised the importance of large-scale digital mass surveillance, the Zimbabwean context reveals complex assemblages of ‘big data’, social media and other digital monitoring combining with more traditional human surveillance practices. Such inseparable online–offline imbrications compound the scale, scope and impact of surveillance and invite analyses as an integrated ensemble. The paper evidences how these surveillance activities exert chilling effects that vary in form, scope and intensity, and implicate rights essential to the development of personal identity and effective functioning of participatory democracy. Moreover, the data reveals impacts beyond the individual to the vicarious and collective. These include gendered dimensions, eroded interpersonal trust and the depleted ability of human rights defenders to organise and particulate in democratic processes. Overall, surveillance chilling effects exert a wide spectrum of outcomes which consequently interfere with enjoyment of multiple rights and hold both short- and long-term implications for democratic participation
The chilling effects of surveillance and human rights: insights from qualitative research in Uganda and Zimbabwe
No full textStates are increasingly developing and deploying large scale surveillance and AI-enabled analytical capabilities. What is uncertain, however, is the impact this surveillance will have. Will it result in a chilling effect whereby individuals modify their behaviour due to the fear of the consequences that may follow? Understanding any such effect is essential: if surveillance activities interfere with the processes by which individuals develop their identity, or undermine democratic processes, the consequences may be almost imperceptible in the short term but profound over the long term. Currently, surveillance-related chilling effects are not well understood, meaning that insufficient weight is given to their potentially society-wide impacts. This article seeks to help redress this balance. Drawing on empirical research in Zimbabwe and Uganda it highlights how State surveillance has chilled behaviour, with significant implications for rights essential to individual development and democratic functioning, specifically the rights to freedom of expression and to freedom of assembly. Importantly, this qualitative research identifies a pattern of common themes or consequences associated with surveillance in general, allowing us to move beyond hypothetical or individual experiences, and providing a greater understanding of the nuances of surveillance-related effects that can help inform decision-making surrounding large scale digital surveillance
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
