Urban warfare ecology: A study of water supply in Basrah

This article assesses the impact of armed conflict on the drinking water service of Basrah from 1978 to 2013 through an ‘urban warfare ecology’ lens in order to draw out the implications for relief programming and relevance to urban studies. It interprets an extensive range of unpublished literature through a frame that incorporates the accumulation of direct and indirect impacts upon the hardware, consumables and people upon which urban services rely. The analysis attributes a step-wise decline in service quality to the lack of water treatment chemicals, lack of spare parts, and, primarily, an extended ‘brain-drain’ of qualified water service staff. The service is found to have been vulnerable to dependence upon foreign parts and people, ‘vicious cycles’ of impact, and the politics of aid and of reconstruction. It follows that practitioners and donors eschew ideas of relief–rehabilitation–development (RRD) for an appreciation of the needs particular to complex urban warfare biospheres, where armed conflict and sanctions permeate all aspects of service provision through altered biological and social processes. The urban warfare ecology lens is found to be a useful complement to ‘infrastructural warfare’ research, suggesting the study of protracted armed conflict upon all aspects of urban life be both deepened technically and broadened to other cases

Maps, Memories and Manchester: The Cartographic Imagination of the Hidden Networks of the Hydraulic City

The largely unseen channelling, culverting and controlling of water into, through and out of cities is the focus of our cartographic interpretation. This paper draws on empirical material depicting hydraulic infrastructure underlying the growth of Manchester in mapped form. Focusing, in particular, on the 19th century burst of large-scale hydraulic engineering, which supplied vastly increased amounts of clean drinking water, controlled unruly rivers to eliminate flooding, and safely removed sewage, this paper explores the contribution of mapping to the making of a more sanitary city, and towards bold civic minded urban intervention. These extensive infrastructures planned and engineered during Victorian and Edwardian Manchester are now taken-for-granted but remain essential for urban life. The maps, plans and diagrams of hydraulic Manchester fixed particular forms of elite knowledge (around planning foresight, topographical precision, civil engineering and sanitary science) but also facilitated and freed flows of water throughout the city. The survival of these maps and plans in libraries, technical books and obscure reports allows the changing cultural work of water to be explored and evokes a range of socially specific memories of a hidden city. Our aetiology of hydraulic cartographics is conducted using ideas from science and technology studies, semiology, and critical cartography with the goal of revealing how they work as virtual witnesses to an 1 unseen city, dramatizing engineering prowess and envisioning complex and messy materiality into a logical, holistic and fluid network underpinning the urban machine. 1

The twilight of the Liberal Social Contract? On the Reception of Rawlsian Political Liberalism

This chapter discusses the Rawlsian project of public reason, or public justification-based 'political' liberalism, and its reception. After a brief philosophical rather than philological reconstruction of the project, the chapter revolves around a distinction between idealist and realist responses to it. Focusing on political liberalism’s critical reception illuminates an overarching question: was Rawls’s revival of a contractualist approach to liberal legitimacy a fruitful move for liberalism and/or the social contract tradition? The last section contains a largely negative answer to that question. Nonetheless the chapter's conclusion shows that the research programme of political liberalism provided and continues to provide illuminating insights into the limitations of liberal contractualism, especially under conditions of persistent and radical diversity. The programme is, however, less receptive to challenges to do with the relative decline of the power of modern states

Cold temperature does not affect perceived exertion in males and females during submaximal cycling

Background: Perceived exertion is an acknowledged indicator of exercise intensity and homeostasis disturbance of an individual, however, there are few studies that have examined the influence of cold temperatures on perceived exertion measurements. Cognition is crucial to perception and exposure to cold temperatures can elicit decrements in cognition. Aims & Objectives: The aim of this study was to determine if, and to what extent, exposure to cold environments may influence perceived exertion and cognitive ability. Study Design: Randomised controlled trial. Materials & Methods: Sixteen participants (m= 8, f= 8, age: 22.3 ± 1.7 years (mean ± SD)), completed two trials in a randomised order in COLD (5°C) and CONTROL (18 °C, 55% relative humidity) conditions. During each trial, following a standardised warm up, participants performed a 6-minute cycle ergometer submaximal exercise. Cognitive ability was assessed pre and post exercise with a reaction time (RT) test. Participant’s physiological responses were measured using Rate of Perceived Exertion (RPE), Heart Rate (HR), Oxygen consumption (VO2), Minute Ventilation (VE), Tympanic (Tt) and Skin Temperature (Tsk) continuously during testing. Statistics: Two-way repeated measures Analysis of Variances (ANOVA), were between environmental conditions over time.Data are reported as mean (M) ± standard deviation (SD).Ordinal Friedman ANOVA tests were conducted on RPE data between environmental conditions and gender. Non-parametric descriptive statistics were reported as medians (Mdn) and inter-quartile ranges (IQR) (25th–75thPercentile). Statistical significance was accepted at p 0.05) reported in RPE, VO2 and VEbetween COLD and CONTROL groups, however, significant decreases in Tsk(p= 0.001) and Tt(p= 0.001) were observed in COLD compared to CONTROL groups. Additionally, no significant differences (p > 0.05) in RT occurred between COLD and CONTROL. Furthermore, no significant differences in RPE were established between genders. Conclusions: Short-term exposure to cold temperatures does not significantly affect physical exertion perception or cognitive abilit

A Randomized Controlled Trial of the Effect of Allopurinol on Left Ventricular Mass Index in Hemodialysis Patients

Introduction: Increased left ventricular mass index (LVMI) is associated with mortality in end-stage renal disease. LVMI regression may improve outcomes. Allopurinol has reduced LVMI in randomized controlled trials in chronic kidney disease, diabetes, and ischemic heart disease. This study investigated whether allopurinol would regress LVMI in hemodialysis patients. Methods: This was a randomized placebo-controlled double-blind multicenter trial. A total of 80 patients undergoing regular maintenance hemodialysis were recruited from NHS Tayside, NHS Greater Glasgow and Clyde and NHS Ayrshire and Arran in Scotland, UK. Participants were randomly assigned on a 1:1 ratio to 12 months of therapy with allopurinol 300 mg or placebo after each dialysis session. The primary outcome was change in LVMI, as assessed by cardiac magnetic resonance imaging (MRI) at baseline and 12 months. Secondary outcomes were change in BP, flow-mediated dilation (FMD), augmentation indices (AIx), and pulse wave velocity (PWV). Results: A total of 53 patients, with a mean age of 58 years, completed the study and had MRI follow-up data for analysis. Allopurinol did not regress LVMI (change in LVMI: placebo +3.6 ± 10.4 g/m2; allopurinol: +1.6 ± 11 g/m2; P = 0.49). Allopurinol had no demonstrable effect on BP, FMD, AIx, or PWV. Conclusion: Compared with placebo, treatment with allopurinol did not regress LVMI in this trial

Regionalizing the infrastructure turn : a research agenda

An interdisciplinary ‘infrastructure turn’ has emerged over the past 20 years that disputes the concept of urban infrastructure as a staid or neutral set of physical artefacts. Responding to the increased conceptual, geographical and political importance of infrastructure – and endemic issues of access, expertise and governance that the varied provision of infrastructures can cause – this intervention asserts the significance of applying a regional perspective to the infrastructure turn. This paper forwards a critical research agenda for the study of ‘infrastructural regionalisms’ to interrogate: (1) how we study and produce knowledge about infrastructure; (2) how infrastructure is governed across or constrained by jurisdictional boundaries; (3) who drives the construction of regional infrastructural imaginaries; and (4) how individuals and communities differentially experience regional space through infrastructure. Analysing regions through infrastructure provides a novel perspective on the regional question and consequently offers a framework to understand better the implications of the current infrastructure moment for regional spaces worldwide

Concrete stories, decomposing fictions: Body parts and body politics in Ahmed Saadawi’s Frankenstein in Baghdad

This essay reads the English translation of Ahmed Saadawi’s novel Frankenstein in Baghdad (2018) to explore the “concrete stories” and “infrastructural narratives” devised by the US military in support of its occupation of Baghdad. By stitching together a city and society littered with composing and decomposing fictions, Saadawi’s novel reveals how biopolitical governance produces, contra the hegemonic US war story of security consolidation and societal stabilization, pervasive insecurity instead. Saadawi’s “decomposing fictions”, as I call them, operate on three homologous terrains: the (de)composition of the city; the (de)composition of the body; and the (de)composition of the narrative itself. Through this three-tired conflation, Saadawi shows how body parts are biopolitical, and how narratives actively and materially reshape human bodies and urban infrastructures. The essay therefore argues that the novel aligns with a critical posthumanist perspective, one that allows for a more rigorous consideration of narrative systems (including fictions) as constitutive of and impactful upon human and non-human bodies and urban infrastructures than other concepts, such as “planned violence”, have so far allowed. By theorizing a more complex relationship between narrative form and the built environment in the contexts of militarized colonial and biopolitical urban governance, the essay shows how Saadawi’s novel not only challenges the “imaginative geographies” of the colonial present, but its material infrastructures as well
