Varieties of smart urbanism in the UK: discursive logics, the state, and local urban context

This is the author accepted manuscript. The final version is available from Wiley via the DOI in this record.The paper analyses the varieties of smart urbanism to be found in the contemporary urban landscape in the UK. In so doing, it builds on and extends two currently dominant sets of critiques of the smart city: those that call into question its technocratic and top-down modes of governance, and those that describe the smart city as an empty signifier. The paper makes sense of the UK’s variegated local smart urban practices, by tracing the emergence of a national, state-led cultural economy of smart urbanism. Based on an analysis of smart city programmes in 34 UK cities, we identify two broad discursive logics through a national variation of smart urbanism is produced and performed. First, the invocation of crisis forms a discursive foundation on which place-specific logics are based. Second, a set of what we term variegated logics are differently combined to build on the ‘foundational story’ of crisis, in the construction of local smart agendas. We discuss three of these variegated logics: the city portrayed as technological simulacrum; the focus on specific sectoral activities; and a chameleonic tendency to envelop previous eco-urban agendas into smart urbanism. The critical questions raise by these UK-specific logics demonstrate the value of considering particular multi-scalar constellations of smart urbanism through a cultural economy lens

Ordinary Chinese Smart Cities: The Case of Wuhan

This is the author accepted manuscript. The final version is available from Routledge via the link in this recordCommentaries on future-oriented Chinese urban development tend to focus on showcase projects underway in wealthy coastal cities. This chapter instead sheds light on the way that the smart has been integrated into more ‘ordinary’ Chinese urban life, using the case of Wuhan, a ‘Tier II’ city in Central China. It explores the conditions of the emergence of Wuhan’s smart city activities from three perspectives. First, it outlines a series of ‘vertical’ enabling factors, whereby an international body of discourse and practice has been ‘translated’ into national Chinese urban policies. Second, it considers the simultaneous significance of ‘horizontal’ links between Wuhan’s local government, city governments abroad, local private enterprises, and foreign firms. Third, it relates Wuhan’s smart credentials to a broader process of digitalisation of everyday life in the city. It concludes by reflecting on the distinctive characteristics of Chinese smart urbanism, as exemplified by Wuhan, and finally draws out some implications for future research into smart cities elsewhere. Specifically, it proposes that the smart city is most usefully approached as a shifting and locally inflected concept which not only channels multiple policy agendas, but also reflects broader changes to urban space and governance in particular contexts.This chapter draws on a research project funded by the Economic and Social Research Council (grant number ES/L015978/1) ‘Smart eco-cities for a green economy: a comparative study of Europe and China’

An Investigation into the Effect of Hydrodynamic Cavitation on Diesel using Optical Extinction

A conventional diesel and paraffinic-rich model diesel fuel were subjected to sustained cavitation in a custom-built high-pressure recirculation flow rig. Changes to the spectral extinction coefficient at 405 nm were measured using a simple optical arrangement. The spectral extinction coefficient at 405 nm for the conventional diesel sample was observed to increase to a maximum value and then asymptotically decrease to a steady-state value, while that for the paraffinic-rich model diesel was observed to progressively decrease. It is suggested that this is caused by the sonochemical pyrolysis of mono-aromatics to form primary soot-like carbonaceous particles, which then coagulate to form larger particles, which are then trapped by the filter, leading to a steady-state spectral absorbance

Solar energy at the peri-urban frontier: An energy justice study of urban peripheries from Burkina Faso and South Africa

This is the final version. Available on open access from Elsevier via the DOI in this recordData availability: Data will be made available on request.Most of the global population that lack access to electricity services live in sub-Saharan Africa. Peri-urban areas of large African cities, often characterized by the presence of informal settlements, exist in a kind of ‘scalar limbo,’ unable to benefit from either access to the city grid or from programs aimed at the electrification of rural areas. In addition, in those areas where lack of electricity access is common, energy poverty combined with proximity to the grid leads to a greater likelihood of illegal energy supply arrangements. In this fieldwork-based study, conducted through population surveys and interviews in the peripheries of Ouagadougou, Burkina Faso, and Cape Town, South Africa, we employ a hybrid theoretical framework, based on work in urban political ecology and energy justice, to analyze the situation of electricity access in the two areas. We find that the planned scale, scope, and technological design of solar energy projects in peripheral areas are crucial in determining whether and how a project will be beneficial for local communities. This study provides guidance beyond academia to national and international policymakers and executives of renewable energy companies, as well as tools for a more in-depth assessment of energy justice issues.ERA4CSEuropean Union Horizon 2020Economic and Social Research Council (ESRC)British AcademyAXA Research Fun

Extensive Sclerosing Mesenteritis of the Rectosigmoid Colon Associated with Erosive Colitis

Sclerosing mesenteritis is a rare, idiopatic, usually benign, inflammatory process of the mesenteric adipose tissue. The most common site of involvement is the small bowel mesentery. We present a case of sclerosing mesenteritis of the rectosigmoid colon as a cause of severe abdominal pain, abdominal obstruction, and ischemic colic mucosal lesions. Contrast enema, colonoscopy, angiography, and CT were the imaging modalities used. A 20 cm diameter, fibrotic mass causing extensive compression of rectosigmoid colon was found at laparotomy. Histological examination showed extended fibrosis, inflammatory cells infiltration, lipophages, and granulomas within the mesenteric adipose tissue associated with erosive colitis. Clinical presentation and treatment are discussed

Smart Eco-CityDevelopment in Europe and China: Opportunities, Drivers and Challenges

The policy pointers presented in this report are the result of a three-year (2015-18) research project led by Federico Caprotti at the University of Exeter. The project, Smart Eco-Cities for a Green Economy: A Comparative Analysis of Europe and China, was delivered by a research consortium comprising scholars and researchers in the UK, China, the Netherlands, France, and Germany. The aim of the project was to investigate the way in which smart city and eco-city strategies are used to enable a transition towards digital and green economies. While previous work has considered smart cities and eco-cities as separate urban development models, the project considers them together for the first time. We use the term ‘the smart eco-city’ to focus on how green targets are now included in smart city development policies and strategies. This report presents a summary of policy pointers, or ‘lessons’, learned through our work on the cities we studied in the UK, China, the Netherlands, France and Germany. Specifically, we studied, in depth, the cities of Manchester, Amsterdam, Hamburg, Bordeaux, Shanghai, Shenzhen, Ningbo and Wuhan. This work included interviews with policymakers, urban municipal authorities, tech firm executives, and grassroots and community representatives and stakeholders. Our work also included intensive and in-depth qualitative analysis of documentary sources including policy and corporate reports and other materials.The research undertaken to produce this report was supported by funding from: the Economic and Social Research Council (ESRC) through research grant ES/ L015978/1; the National Natural Science Foundation of China, project number 71461137005; the Netherlands Organisation for Scientific Research (NWO) through research grant 467-14-153 and the Dutch Academy of Sciences (KNAW) through research grant 530-6CD108; the French National Research Agency (ANR) through research grant ANR-14-02; and the German Research Foundation DFG through research grant SP 1545/1-1
