Resilience of Self-Organised and Top-Down Planned Cities—A Case Study on London and Beijing Street Networks

The success or failure of the street network depends on its reliability. In this article, using resilience analysis, the author studies how the shape and appearance of street networks in self-organised and top-down planned cities influences urban transport. Considering London and Beijing as proxies for self-organised and top-down planned cities, the structural properties of London and Beijing networks first are investigated based on their primal and dual representations of planar graphs. The robustness of street networks then is evaluated in primal space and dual space by deactivating road links under random and intentional attack scenarios. The results show that the reliability of London street network differs from that of Beijing, which seems to rely more on its architecture and connectivity. It is found that top-down planned Beijing with its higher average degree in the dual space and assortativity in the primal space is more robust than self-organised London using the measures of maximum and second largest cluster size and network efficiency. The article offers an insight, from a network perspective, into the reliability of street patterns in self-organised and top-down planned city systems.     

The Great Stench or the fool's argument.

The eight weeks of the "Great Stench" in London in June-July 1858 had a lasting effect on the city. Today's embankments were planned then, and the huge oval brick sewers of London were designed and constructed as a direct result of the stench. The event occurred before the bacteriological era, when fear of cholera caused by a miasma gripped the city. This article, through quotations from The Times, Punch, and the medical press, traces the various reactions to the stink and explores the reasons why there wasn't more of a public reaction to the plague threat.     

'Blog This': surfing the metropolis and the method of London

This article examines the ways in which a group of London webloggers or on-line journal keepers constitute their city. They claim that their strategies for knowing London are derived from techniques for knowing the Internet. In particular, webloggers adapt the activity and culture of on-line surfing. The article investigates the method of 'blogging' alongside and against the interpretative strategies deployed by urban theorists and sketch writers. It is intended as a contribution to urban anthropology, anthropology of the Internet, the anthropology of knowledge, and the ethnography of London.  

Résumé

L'auteur examine la manière dont un groupe de blogueurs ou d'auteurs de journaux en ligne londoniens constituent leur ville. Il affirme que leurs stratégies pour connaître Londres s'inspirent des techniques employées pour connaître Internet. En particulier, les webloggers ont adapté l'activité et la culture de la navigation en ligne. L'article étudie la méthode de « blogging >> parallèlement et en comparaison avec les stratégies interprétatives déployées par les théoriciens de l'urbanisme et les planificateurs. Cet article se veut une contribution à l'anthropologie urbaine, à l'anthropologie de l'Internet, à l'anthropologie de la connaissance et à l'ethnographie de Londres.     

Edible wild plants of the Chorote Indians, Gran Chaco, Argentina

The Chorote Indians are hunter-gatherers and fishermen from north-west Argentina and south-west Paraguay who belong to the Mataco-Maká linguistic family. Their edible plants are identified by botanical and vernacular names, the parts employed and modes of preparation and consumption. The Chorote people use 57 plant species as a source of food, which they consume in 118 different ways. Five new edible species, that yield seven plant foods, are reported here for the first time for Chaquenian ethnic groups. However, only a few wild plant foods are in frequent use today, with most being used occasionally, infrequently or not at all. A cross-cultural comparison with four neighbouring ethnic groups reveals that one third of their plant foods are exclusive to the Chorote people, despite the fact that they share most of their edible plants with the other groups. This article is the first contribution to an understanding of the Chorote's ethnobotany and to a comparison of interethnic relationships concerning their edible plant resources.  © 2007 The Linnean Society of London, Botanical Journal of the Linnean Society , 2007, 153 , 73–85.     

Nigerian London: re-mapping space and ethnicity in superdiverse cities

This paper explores the idea of ‘superdiversity’ at the city level through two churches with different approaches to architectural visibility: the hypervisible Universal Church of the Kingdom of God and the invisible Igbo Catholic Church, both in North London, guide our exploration of invisible Nigerian London. Although Nigerians have lived in London for over 200 years, they live beneath the radar of policy and public recognition rather than as a vital and visible element of superdiversity. This paper argues that we can trace the journeys composing Nigerian London in the deep textures of the city thus making it visible, but this involves re-mapping space and ethnicity. It argues that visibility is vital in generating more open forms of urban encounter and, ultimately, citizenship.     

Salamanca and the city: culture credits, nature credits, and the modern moral economy of indigenous Bolivia

This article draws on fieldwork carried out in a Guaraní-speaking community in the Bolivian Chaco – Isoso – between 1997 and 2000. At the time, some Isoseño people were employed in urban-headquartered projects that revolved around Isoso's environment, culture, or identity and that were funded multilaterally by grants, loans, or other foreign aid. The article describes a set of fantastic discourses circulating in rural Isoso that seem to compare a magical place called Salamanca to the city where some Isoseño people now work. The article argues that these Salamanca discourses are an Isoseño-specific way of talking about a general set of unprecedented processes. It takes up the fact that undertakings of the kind in which the Isoseño are involved create new calibrations among radically different systems for moral/qualitative and material/ quantitative evaluation which can most 'economically' be expressed in terms of credit and debt. Finally, it considers why it is that for all their strange magic, Isoseño 'Salamanca and the city' discourses put an extremely recognizable suite of moral considerations at their centre.     

Ethnic diversity,segregation and the social cohesion of neighbourhoods in London

The question of whether and how ethnic diversity affects the social cohesion of communities has become an increasingly prominent and contested topic of academic and political debate. In this paper we focus on a single city: London. As possibly the most ethnically diverse conurbation on the planet, London serves as a particularly suitable test-bed for theories about the effects of ethnic heterogeneity on prosocial attitudes. We find neighbourhood ethnic diversity in London to be positively related to the perceived social cohesion of neighbourhood residents, once the level of economic deprivation is accounted for. Ethnic segregation within neighbourhoods, on the other hand, is associated with lower levels of perceived social cohesion. Both effects are strongly moderated by the age of individual residents: diversity has a positive effect on social cohesion for young people but this effect dissipates in older age groups; the reverse pattern is found for ethnic segregation.     

Utz Wachil: Findings from an International Study of Indigenous Perspectives on Health and Environment

This article reports previously unpublished results of a collaborative study undertaken in 2003 by health workers of the UK-based organisation Health Unlimited, and by researchers of the London School of Hygiene and Tropical Medicine. This study marked the first of a series of collaborative activities aimed at highlighting the situation of Indigenous peoples, some in the most isolated ecosystems of the planet. While many researchers focus on quantitative analysis of the health and environmental conditions of Indigenous peoples, our 2003 study aimed at exploring the views of Indigenous peoples in isolated communities in five countries on their environment and their health. In this article we look closely at the web of knowledge and belief that underpins Indigenous peoples’ concepts of health and well-being, and their relationship to land and the environment. Although many Indigenous people have been forced off their traditional lands and live in rural settlements, towns, and cities, there are still a large number of people living in very small Indigenous communities in remote areas. This article focuses on 20 such communities in six countries. We explore traditional knowledge and practice and its relationship to Western medicine and services. The research findings highlight the importance of Indigenous knowledge systems for the emerging ecohealth community and suggest that we have much to learn from Indigenous peoples in our pursuit of a more holistic science. Utz Wachil is from the K’iche language originating in Totonicapan Department, Guatemala. It translates literally as “fine/well face-ness,” face meaning one’s aspect in general, not only physical appearance.     

On Space As A Capacity

This article is about space and social relationships. More precisely, it is about the space of and in social relationships. It is also about the efficacy of social relationships in segregating their own contexts of meaning and value. The article also addresses the question of how agency comes about. This 'coming about' of agency, its swelling and appearance in a structure of meaning, is what I call 'capacity'. Social relationships have 'capacity'. That is, they have both spaciousness and potency. They accomplish things, and accomplish things 'somewhere'. In this respect, space (or the capacity of social relationships) is something very different from idioms that we have come to think of as forms of space, like landscape or place. This article is also, therefore, a critique of the way in which some anthropologists have recently theorized landscape and place. My argument is based on an ethnographic account of the dimensions through which people construct urban space in the Chilean city of Antofagasta.     

When and What Parents Tell Children About Race: An Examination of Race-Related Socialization Among African American Families

This article describes a developmental systems approach to applied developmental science (ADS), which provides a framework to design and evaluate technology-rich programs that promote positive development by emphasizing the strengths and assets of young people instead of focusing on diminishing or preventing risk-taking behaviors. Until now, most of the psychoeducational programs conceived within the ADS model have not focused on the role of new technologies in young people's lives. This absence is particularly striking given that, in today's world, new technologies play an important role in different areas of the lives of young people, such as education, entertainment, socialization, and communication. This article presents the concept of identity construction environments (ICE), an interdisciplinary model that proposes guidelines to design and study new technologies purposefully created to promote positive youth development (PYD). Two types of ICE have been developed: one focusing on stand-alone technologies for learning, such as the Zora virtual city; and the other focusing on an approach for developing technologically rich learning contexts, such as the Project Inter-Actions robotics workshops. This article presents both examples of ICE and describes how their design fosters the 6 components of PYD. Initial findings from pilot studies conducted with very different populations of youth engaged in both types of ICE—such as young children, adolescents, and chronically ill children—are presented.     

‘It's true,I'm English… I'm not lying’: essentialized and precarious English identities

This article explores relationships between Englishness and racialization in order to consider the potential for English identities that are progressive in anti-essentialist or multicultural terms. The article draws on data from interviews in which people from a South London area talk about Englishness. I will examine how English identities are understood by participants who are white and participants who are not white. While white participants experience Englishness as a taken-for-granted identity, for participants who are not white English identities are a more calculated, precarious performance. I will then examine discussions of ‘who can be English’. While most participants argue that ‘anyone can be English’ in principle, this is not necessarily the case in practice. It will be suggested that talk of Englishness is particularly constrained by relationships between Englishness, whiteness and ancestry, but that for those who experience Englishness as precarious there are signs that this is not necessarily the case.     

Distribution, habitat utilization and age structure of a suburban fox (Vulpes vulpes) population

The occurrence of wild foxes in suburbia is discussed. It is shown that in London breeding populations of foxes are found 5 km from the city centre, and in the last 3 years foxes have been recorded in the very centre of the city. The fox population in London is shown to be heavily dependent on residential habitats for both daytime harbourage and when selecting sites for natal earths. The fox population is unevenly distributed in London, with a marked clumping of the adult population during most of the year. The age structure of the population is presented, and these data are compared with data for other canid populations. Conclusions are drawn as to the effects of conventional control techniques on the age structure of a fox population.     

Putting the Ninth Ward on the Map: Race, Place, and Transformation in Desire, New Orleans

In this article, we consider how long-term patterns of resistance to structural violence inform citizens' responses to displacement before and after Katrina. Drawing on Abdou Maliq Simone's (2004) conceptualization of people as infrastructure, we recenter the discussion about the rebuilding of New Orleans around displaced residents, taking the place-making practices of members of a social club as a lens through which to examine the predicament of the city as a whole. Members have been generating alternative ways of thinking about and dwelling together in a restructuring city. Their perspectives are articulated through in-depth interviews, focus groups, and the embodied practices of club members and their followers as they make claims to the city through massive, participatory street processions known as second lines. These distinctive ways of thinking and being in the city—the subaltern mainstream of the second-line tradition—are now being deployed by exiled New Orleanians reconsidering their relationship to home.     

Close relatives and outsiders: village people in the city of Yakutsk, Siberia

The paper presents a snapshot of the city-village connections in the city of Yakutsk and an anthropological account of the dynamics of the relationship between the city and villages around it. Demographic changes that started in the 1980s, prompted by a decline in agriculture, initiated an exodus of the rural population from the countryside into the city of Yakutsk. This paper explores the migration dynamics of the rural population to the city. Two conflicting aspects of the relationship between the city and village are the focus of this paper: treating village people as close kin and as outsiders. I examine the image of ulusnik [a villager] and consider rationales behind the stigma attached to it and a social role of the Other which is imposed on the people from the countryside.     

Super-diverse street: a ‘trans-ethnography’ across migrant localities

This paper emerges from an ethnography of the economic and cultural life of Rye Lane, an intensely multi-ethnic street in Peckham, South London. The effects of accelerated migration into London are explored through the reshaping and diversification of its interior, street and city spaces. A ‘trans-ethnography’ is pursued across the compendium of micro-, meso- and macro-urban spaces, without reifying one above the other. The ethnographic stretch across intimate, collective and symbolic city spaces serves to connect how the restrictions and circuits of urban migration have different impacts and expressions in these distinctive but interrelated urban localities. The paper argues for a trans-ethnography that engages within and across a compendium of urban localities, to understand how accelerated migration and urban ‘super-diversity’ transform the contemporary global city.     

Feral ecologies: the making of postcolonial nature in London

Through an ethnography of parakeets and other denizens in London, this article expounds the concept of the feral and foregrounds its purchase for an anthropological inquiry into urban life. Ecological, cultural, and political connotations of ferality impinge upon evaluations of what counts and is allowed to flourish as metropolitan nature. Ferality is constructed through nativist and racial taxonomies which promote a biopolitics of eradicating parakeets. At the same time, parakeets trigger new ‘recombinant' ecological associations when they enter into relations with other avian life. They also foster affective alignments with people that create possibilities for a more just politics of dwelling. The feral recasts London's metropolitan nature as postcolonial and opens up novel ways of doing urban anthropology.     

Sinuses and flotation: Does the aquatic ape theory hold water?

The idea that people went through an aquatic phase at some time in their evolutionary past is currently undergoing a popular resurgence (see Foley & Lahr 1 ). This idea has even started to gain some traction in more learned circles; the late paleoanthropologist Phillip Tobias wrote in support of aspects of it in an edited e‐book 2 and a conference on the topic held recently in London was endorsed by celebrities such as the television presenter Sir David Attenborough. 3 Despite (or perhaps because of) the lack of interest within the academic community, advocates of the concept continue to fill the media (and blogosphere) with challenges to the “savannah hypothesis” of the origins of people and to bemoan the fact that their views are not taken seriously by mainstream academia.     

The market for medicinal plants in sapa and hanoi, vietnam

The Market for Medicinal Plants in Sapa and Hanoi, Vietnam. Economic Botany 59(4):377-385, 2005. This article describes the market for medicinal plants sold in the Vietnamese town of Sapa as well as in nine different markets in the Vietnamese capital city, Hanoi. A total of 44 medicinal plants were identified botanically, 27 of which are on sale in Sapa and 28 in Hanoi. Most buyers of medicinal plants in Sapa are members of the Vietnamese middle classes who go to Sapa on holidays. Medicinal plants are gathered or cultivated predominantly by members of ethnic minority groups (Hmong and Dao) who live in small hamlets, some located several hours from the town of Sapa. Sapa is one of the poorest districts in Vietnam with a GDP per household of only U.S. $322 in 2005, so the cash that people are able to earn from the sale of medicinal plants is very important. The article argues that the social roles of the weekend market in Sapa are equally important, as the market helps ethnic minorities to fulfil their needs for a social life beyond the village.     

Utilisation by homeless people of acute hospital services in London.

OBJECTIVES--To estimate the numbers and distribution of homeless people in London; to quantify the utilisation of acute inpatient services by homeless people in two health authorities; and to predict the total numbers of admissions in homeless people in district health authorities across London. DESIGN--Data were collected from various sources on the distribution of homeless people across London boroughs. All unplanned acute inpatient admissions during November 1990 to relevant hospitals were identified. SETTING--Bloomsbury and Paddington and North Kensington, two former inner London district health authorities. SUBJECTS--Homeless people in London residing in bed and breakfast and private sector leased accommodation, residing in hostels, and of no fixed abode. MAIN OUTCOME MEASURES--Number and cost of acute unplanned admissions in homeless people in two health authorities in November 1990; predicted number of such admissions each year in district health authorities in London. RESULTS--There were at least 60,000 homeless people in London in March 1990. The majority were housed in temporary accommodation (55,412). There were at least 3295 hostel dwellers and 651 people sleeping rough. Homeless people accounted for 105 (8%) of the 1256 acute unbooked admissions in residents of Bloomsbury and Paddington and North Kensington health authorities in November 1990. Considerable variations in the pattern of acute unplanned admissions in homeless people were observed in the two districts with respect to housing status and specialty of admission. The total number of acute unplanned admissions in homeless people across London each year was estimated at 7598, ranging from 38 in Bexley to 1515 in Parkside. CONCLUSIONS--The results have fundamental implications for resource allocation across London. Allocation must take better account of the heterogeneity, uneven distribution, and extra health needs of homeless people.
