The mobility restrictions related to COVID-19 pandemic have resulted in the biggest disruption to individual mobilities in modern times. The crisis is clearly spatial in nature, and examining the geographical aspect is important in understanding the broad implications of the pandemic. The avalanche of mobile Big Data makes it possible to study the spatial effects of the crisis with spatiotemporal detail at the national and global scales. However, the current crisis also highlights serious limitations in the readiness to take the (...) advantage of mobile Big Data for social good, both within and beyond the interests of health sector. We propose two strategical pathways for the future use of mobile Big Data for societal impact assessment, addressing access to both raw mobile Big Data as well as aggregated data products. Both pathways require careful considerations of privacy issues, harmonized and transparent methodologies, and attention to the representativeness, reliability and continuity of data. The goal is to be better prepared to use mobile Big Data in future crises. (shrink)

We are experiencing a historical moment characterized by unprecedented conditions of virality: a viral pandemic, the viral diffusion of misinformation and conspiracy theories, the viral momentum of ongoing Hong Kong protests, and the viral spread of #BlackLivesMatter demonstrations and related efforts to defund policing. These co-articulations of crises, traumas, and virality both implicate and are implicated by big data practices occurring in a present that is pervasively mediated by data materialities, deeply rooted dataist ideologies that entrench processes of datafication as (...) granting objective access to truth and attendant practices of tracking, data analytics, algorithmic prediction, and data-driven targeting of individuals and communities. This collection of papers explores how data is figuring in the making of the discourses, lived realities, and systemic inequalities of the uneven impacts of the coronavirus pandemic. (shrink)

Using Big Data to better understand urban questions is an exciting field with challenging methodological and theoretical problems. It is also, however, potentially troubling when Big Data is applied uncritically to urban governance via the ideas and practices of “smart cities”. This essay reviews both the historical depth of central ideas within smart city governance —particular the idea that enough data/information/knowledge can solve society problems—but also the ways that the most recent version differs. Namely, that the motivations and ideological underpinning (...) behind the goal of urban betterment is largely driven by technology advocates and neoliberalism rather than the strong social justice themes associated with earlier applications of data to cities. Geosocial media data and metrics derived from them can provide useful insight and policy direction. But one must be ever mindful that metrics don’t simply measure; in the process of deciding what is important and possible to measure, these data are simultaneously defining what cities are. (shrink)

This article introduces a series of measures of the geographical manifestation of a subset of unsolicited commercial email, i.e. spam, used to perpetrate 'advanced fee fraud'. Known as '419 spam', this activity has strong historic ties to Nigeria, where similar frauds were operated via physical letters and faxes during the 1970s and 1980s. This article's analysis reveals that 419 spam operates via a globally dispersed network that nevertheless contains a clear agglomeration of activity in West Africa. Building upon theories of (...) the intersection of cyberspace, states, and individuals, this article argues that 419 spam exemplifies the challenge offered by the Internet to the dominance of states by allowing individuals and movements to create social space that transcends borders. This process is an intriguing and ironic parallel to the description of the rise of the European nation-state as an 'imagined community' that challenged medieval systems of authority and existing social epistemologies. The emerging 'networks of imagination' developed by transnational social movements and criminal networks to define their sphere of operations present a similar challenge to the primacy of existing authority embedded in the state, particularly for states in crisis such as Nigeria. The article concludes with an examination of the off-line and online implications of 419 spam and its network of imagination for the Nigerian state and its inhabitants. Ranging from strengthening public conceptions of West Africa as a sea of corruption to a decreased ability to interact with the outside world, 419 spammers are playing an important, if illicit, role in the construction and use of Nigeria's and the world's Internet.
