Contesting Digital Futures: Urban Politics, Alternative Economies, and the Movement for Technological Sovereignty in Barcelona
Scholars have offered important critiques of the socioâspatial processes of contemporary technological development, including the rise of âsmart cityâ urban development models. While these critiques have been essential for understanding contemporary forms of technoâcapitalism and their reach into new areas, this paper calls for a consideration of alternative modes of digital development in urban life beyond the logics of securitisation and capital accumulation. In particular, I examine the critical discourses and experimental practices of a grassroots movement focused on claiming âtechnological sovereigntyâ (TS) in Barcelona. The TS movement is a broad, deâcentralised network of cooperatives, associations, and community initiatives experimenting with alternative practices of locally rooted, openâsource digital development. These groups explore democratic and cooperative practices of work, property, production, and consumption in relation to digital technology, based around an ethics of care and a commitment to working through and within local communities. In examining the values, beliefs, and practices of the TS movement, I bring ongoing discussions around digitalisation and the âsmart cityâ into critical conversation with the extensive literature on prefigurative urban politics and postcapitalist economies.This research received funding from the WennerâGren Foundation for Anthropological Research, the Social Science Research Council DPDF Program, and a Fulbright US Student Award.12 month embargo; first published: 12 March 2019This item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

Raising the carbonized forest: Science and technologies of singularization
Recognizing the potential of forests to store carbon, various policies and programs have emerged to enhance this potential as a climate mitigation strategy. While the effectiveness of these policies is highly debated, there can be no doubt that they have profoundly affected how forests are conceptualized, valued, and governed. In this article, we discuss how science supports this increasing carbonization of forests not just by focusing knowledge production processes on carbon, but also by supporting policies and programs that aim to efficiently manage forests to optimize their carbon value. We situate this process in a longer history to show how science operates as technology of singularization that, guided by principles of optimization and efficiency, contributes to the depoliticization and normalization of specific versions of the forest that foreground singular priority values, while subsuming and marginalizing of other ways of knowing, valuing, and living with forests. Although emerging practices in techno-science, including the adoption of smart technologies and automated forms of data generation and analysis, can potentially enhance understanding of multiple forest values, we argue that they are likely to intensify singularization and create ever tighter relationships between knowledge production and forest management. We conclude by discussing the need to counter and refuse singularization
Evolving spatialities of digital life: Troubling the smart city/home divide
While feminist geographers have long aimed to trouble conceptions of the city/home (and, by extension, public/private) divides, the digital city and the digital home are still often theorized as separate phenomena within much digital geography literature. Drawing on previous work on feminist home-city geographies, this paper proposes four analytical frames for reflecting on the relationship between urban and domestic space in digital geographies: governance, domestication, thresholds, and dwelling. The paper explores each lens through a critical review of recent literature in digital geographies and related fields. It weaves this review through a speculative reading of the Eco Delta Smart City, an experimental development building the smart city from the home up in Busan, South Korea. We show how each lens calls attention to distinct sets of questions, actors, agendas, and relationsâthus refusing any single reading of the project or of the broader trends around digitalization of which it is a part. In the process, we trace how digitalization does not simply trouble existing spatial categories, but rather makes them manifest in new ways for differently situated subjects
Blockchain urbanism: Evolving geographies of libertarian exit and technopolitical failure
Libertarian âexitâ imaginaries project new social, political, and economic structures separate from existing institutions in which âsovereign individualsâ can opt-in to the governing system that fits their ideals. This paper traces libertarian exit imaginaries through a variety of territorial and technological projects. Demonstrating how these imaginaries evolve, it describes a recent proposal to build a semi-autonomous, blockchain-based smart city in Nevada. Reflecting on these projects, the paper highlights (1) their inevitable failure as they confront reality, (2) their role as spectacle, spreading libertarian ideology, and (3) their real-life impacts on distinct places and communities even when they fail or never materialize
Robotics in place and the places of robotics: productive tensions across human geography and humanârobot interaction
Bringing humanârobot interaction (HRI) into conversation with scholarship from human geography, this paper considers how socially interactive robots become important agents in the production of social space and explores the utility of core geographic concepts of scale and place to critically examine evolving robotic spatialities. The paper grounds this discussion through reflections on a collaborative, interdisciplinary research project studying the development and deployment of interactive museum tour-guiding robots on a North American university campus. The project is a collaboration among geographers, roboticists, a digital artist, and the directors/curators of two museums, and involves experimentation in the development of a tour-guiding robot with a âsocially aware navigation systemâ alongside ongoing critical reflection into the socio-spatial context of humanârobot interactions and their future possibilities. The paper reflects on the tensions between logics of control and contingency in robotic spatiality and argues that concepts of scale and place can help reflect on this tension in a productive way while calling attention to a broader range of stakeholders who should be included in robotic design and deployment
The Bacteroidales produce an N-acylated derivative of glycine with both cholesterol-solubilising and hemolytic activity.
The contribution of the gut microbiota to the metabolism of cholesterol is not well understood. In this study, we identify 21 fosmid clones from a human gut microbiome metagenomic library that, when expressed in Escherichia coli, produce halos on LB agar supplemented with 0.01% (w/v) cholesterol (LBC agar). Analysis of 14 of these clones revealed that they all share a fragment of DNA with homology to the genome of Bacteroides vulgatus. The gene responsible for halo production on LBC agar, named choA, was identified as an N-acyltransferase known to produce an acylated glycine molecule called commendamide. In this study we show that commendamide is capable of producing a halo on LBC agar suggesting that this molecule is solubilizing the cholesterol micelles in LBC agar. We also show that commendamide is responsible for the previously described hemolytic activity associated with the choA orthologue in Bacteroides fragilis. A functional analysis of ChoA identified 2 amino acids that are important for commendamide biosynthesis and we present phylogenetic and functional data showing that orthologues of choA are found only in the order Bacteroidales. Therefore, the production of commendamide may be an adaptation to the environments colonized by the Bacteroidales, including the mammalian gut
Performance of anti-Salmonella lactic acid bacteria in the porcine intestine
Of five anti-Salmonella porcine cultures administered to pigs at 1010 cfu/day, two Lactobacillus murinus strains demonstrated superior survival during gastrointestinal transit. Both were detected at ~107 -108 cfu/g faeces which was higher (P\u3c0.05) than Pediococcus pentosaceus DPC6006 (~105 cfu/g). One Lb. murinus strain was also excreted at higher numbers (P\u3c0.05) than either Lb. salivarius DPC6005 or Lb. pentosus DPC6004 (both ~106 cfu/g). The Lb. murinus strains persisted in both the faeces and the caecum for at least 9 days post-administration. Animals fed a combination of all five strains at 1010 cfu/day excreted ~107 cfu/g of the administered strains, which was higher (P\u3c0.05) than only P. pentosaceus DPC6006. Randomly amplified polymorphic DNA (RAPD) PCR analysis revealed that both Lb. murinus strains predominated in the faeces of these animals during administration, while post-administration, both Lb. murinus strains and Lb. pentosus DPC6004 were recovered from the faeces and the caecum while P. pentosaceus DPC6006 was only detected in the caecum. After 21 days of culture administration, faecal Enterobacteriaceae counts were reduced in pigs fed Lb. salivarius DPC6005, P. pentosaceus DPC6006, Lb. pentosus DPC6004 and the culture mix, though not significantly. Overall, the porcine intestinal isolates offer potential as probiotics for enteropathogen reduction in pigs; possibly as a combination due to strain variation
Constellations of identity: place-ma(r)king beyond heritage
This paper will critically consider the different ways in which history and belonging have been treated in artworks situated in the Citadel development in Ayr on the West coast of Scotland. It will focus upon one artwork, Constellation by Stephen Hurrel, as an alternative to the more conventional landscapes of heritage which are adjacent, to examine the relationship between personal history and place history and argue the primacy of participatory process in the creation of place and any artwork therein. Through his artwork, Hurrel has attempted to adopt a material process through which place can be created performatively but, in part due to its non-representational form, proves problematic, aesthetically and longitudinally, in wholly engaging the community. The paper will suggest that through variants of ânew genre public artâ such as this, personal and place histories can be actively re-created through the redevelopment of contemporary urban landscapes but also highlight the complexities and indeterminacies involved in the relationship between artwork, people and place
Intercomparison of shallow water bathymetry, hydro-optics, and benthos mapping techniques in Australian and Caribbean coastal environments
Science, resource management, and defense need algorithms capable of using airborne or satellite imagery to accurately map bathymetry, water quality, and substrate composition in optically shallow waters. Although a variety of inversion algorithms are available, there has been limited assessment of performance and no work has been published comparing their accuracy and efficiency. This paper compares the absolute and relative accuracies and computational efficiencies of one empirical and five radiative-transfer-based published approaches applied to coastal sites at Lee Stocking Island in the Bahamas and Moreton Bay in eastern Australia. These sites have published airborne hyperspectral data and field data. The assessment showed that (1) radiative-transfer-based methods were more accurate than the empirical approach for bathymetric retrieval, and the accuracies and processing times were inversely related to the complexity of the models used; (2) all inversion methods provided moderately accurate retrievals of bathymetry, water column inherent optical properties, and benthic reflectance in waters less than 13 m deep with homogeneous to heterogeneous benthic/substrate covers; (3) slightly higher accuracy retrievals were obtained from locally parameterized methods; and (4) no method compared here can be considered optimal for all situations. The results provide a guide to the conditions where each approach may be used (available image and field data and processing capability). A re-analysis of these same or additional sites with satellite hyperspectral data with lower spatial and radiometric resolution, but higher temporal resolution would be instructive to establish guidelines for repeatable regional to global scale shallow water mapping approaches
