(Re)birthing the maternal

The aim of this essay is to explore the political and ethical potential of (re)birthing through Barad’s conceptualisation of transmateriality. This article puts Barad’s thought on entanglement, emergence, and responsibility into conversation with other work in feminist philosophy and psychoanalysis that has grappled with questions of the maternal, birthing, and ethics. On the one hand, this encounter suggests that there are other ways of posing questions of separation, responsibility, and power through the maternal that might challenge aspects of Barad’s telling. But at the same time, by bringing Barad’s thought into these conversations, I show how Barad’s transpositions of (re)birthing have the potential to radically re-open and trans*figure feminist ethics and politics via a more dispersed, immoderate, and ultimately queer perspective on how the ethics that inheres in the coming into (non)being of the world

Spacetimeunconscious

This article argues for an understanding of material geographies as invested with an unconscious dimension. I put forward the notion of spacetimeunconscious not as an inverse, double, or ‘other’ to Karen Barad's concept of spacetimematter, but as a supplement. Manifesting the spacetimeunconscious through the technique of montage, I draw together a range of phenomena, from the icing of water and the flashing of lightning to the awakenings of traumatised and displaced subjects. Across these juxtaposed parts, I argue that the unfolding of space and time responds to the enigmatic, irreducible message of the unconscious in the real. Spacetimeunconscious arrives as the ambassador of an unknown knowledge remembered for – or in the place of – a forgetful substance: water, dreamer, or electron. In an echo of the analytic method, I use montage to create generative connections, discontinuities, and instabilities between events, poetry, literature, and film, in the interstices of which the spacetimeunconscious may make an appearance

Towards a post-mathematical topology

This paper aims to bring clarity to the term topology as it has been deployed in human geography. We summarize the insights that geographers have garnered from thinking topologically about space and power. We find that many deployments of topology both overstretch topology’s conceptual merit and limit its insights for spatial thinking. We show how topology, with its structuralist and modernist baggage, requires some theoretical reworking to be put to work by poststructuralist geographers. Our purpose is not to consolidate a specific topological approach for geographers, but to call for an ongoing consideration of what topology offers poststructuralist spatial theories

Undoing mastery: With ambivalence?

In this commentary, we respond to Derek Ruez and Daniel Cockayne’s article ‘Feeling Otherwise: Ambivalent Affects and the Politics of Critique in Geography’. We do so by picking up ambivalence—or more precisely, ambivalence about ambivalence—as a tool with which Ruez and Cockayne leave us. We find this tool somewhat difficult to grasp, but we understand this as part of its design. Ambivalence undoes the subject’s mastery. In doing so, we find that an airing of ambivalence gives other kinds of entangled, indeterminate, and unknowing relations room to breathe

The space of encounter and the making of difference: The entangled lives of Alevi and Sunni neighbours in Turkey

The concept of encounter has long been central to a cosmopolitan ethos in which coming together in urban public space is expected to yield tolerance and pluralism. More recently scholars have reworked this concept to account for not only what is potentially transformative in encounters but also how encounters are conditioned by and productive of relations of power and inequality. Our study contributes to this reworking, and to feminist critiques of space and politics, by centring the spatiality of encounter in the entanglement of neighbours. Drawing on our focus group research (2013–2016) with Alevis and Sunnis in Istanbul and Malatya, we argue that difficult questions of difference, responsibility, and power come to the fore in neighbour relations. While our study underlines how Sunni supremacism and Alevi precarity are constituted in the everyday lives of neighbours, we also find that there is a transformational potential in these encounters that is not fully (re)absorbed into structures of Alevi–Sunni difference. We argue that, across the blurry boundaries of home and neighbourhood spaces, the unbidden intimacies of living in proximity (the drift of smells and sounds, the lines of sight that connect balconies and windows, the presence of neighbours at the thresholds and in the spaces of each other's homes) mean that encounters between neighbours both fuel and trouble the marking out of what is shared and what is separate, what is tolerable and what crosses a line. Our study thereby advances an understanding of the space of encounter, the making of difference, and the political and ethical significance of this entanglement

Evaluation of Urine CCA Assays for Detection of Schistosoma mansoni Infection in Western Kenya

Although accurate assessment of the prevalence of Schistosoma mansoni is important for the design and evaluation of control programs, the most widely used tools for diagnosis are limited by suboptimal sensitivity, slow turn-around-time, or inability to distinguish current from former infections. Recently, two tests that detect circulating cathodic antigen (CCA) in urine of patients with schistosomiasis became commercially available. As part of a larger study on schistosomiasis prevalence in young children, we evaluated the performance and diagnostic accuracy of these tests—the carbon test strip designed for use in the laboratory and the cassette format test intended for field use. In comparison to 6 Kato-Katz exams, the carbon and cassette CCA tests had sensitivities of 88.4% and 94.2% and specificities of 70.9% and 59.4%, respectively. However, because of the known limitations of the Kato-Katz assay, we also utilized latent class analysis (LCA) incorporating the CCA, Kato-Katz, and schistosome-specific antibody results to determine their sensitivities and specificities. The laboratory-based CCA test had a sensitivity of 91.7% and a specificity of 89.4% by LCA while the cassette test had a sensitivity of 96.3% and a specificity of 74.7%. The intensity of the reaction in both urine CCA tests reflected stool egg burden and their performance was not affected by the presence of soil transmitted helminth infections. Our results suggest that urine-based assays for CCA may be valuable in screening for S. mansoni infections
