After three decades of urban renewal in China, public spaces used by average residents have not been improved proportionally and, in some cases, have even deteriorated. Three problems can be identified. ‘Window-dressing’ prevails in government- developed squares and parks. Their locations and monumentality have made residents less willing to use these spaces. ‘Privatization’ describes how private developers maximize profits at the cost of public life in the urban environment surrounding their projects. ‘Gentrification’, different from its meaning in the West, refers to the tendency to ignore the needs of mid- and low-income residents in public facilities. Not entirely a repetition of the 1950s Western urban renewal, the Chinese cases reflect a society changing from a socialist system to a capitalist one.

What we have are closed, self-absorbed buildings. What we would like to have is open, versatile, interesting and safe cities. The challenge is how to incorporate large buildings in cities where people have the same small stature and slow pace they had hundreds of years ago. There is now a considerable confusion in the gap between large and small scales and between ‘quick’ and ‘slow’ architecture. Ground floor facades provide an important link between these scales and between buildings and people. For public space and buildings to be treated as a whole, the ground floor facades must have a special and welcoming design. This good, close encounter architecture is vital for good cities.

Jane Jacobs's The Death and Life of Great American Cities (1961) had an enormous influence on urban design theories and practices. This study aims to operationalize Jacobs's conditions for a vital urban life. These are (1) mixed use, (2) small blocks, (3) aged buildings, and (4) a sufficient concentration of buildings. Jacobs suggested that a vital urban life could be sustained by an urban realm that promotes pedestrian activity for various purposes at various times. Employing multilevel binomial models, we empirically verified that Jacobs's conditions for urban diversity play a significant role with regard to pedestrian activity.

In 2003, for the second year running, the Paris municipality entrusted a young theater designer with the transformation of one stretch of the banks of the Seine River—normally congested with heavy traffic—into an open space evocative of the seaside. Paris in August is therefore Paris by the seaside. The objective of our study is to examine the entire operation, from the moment the political decision was taken by the municipality to the many and varied activities of all those who participated. Through this study, we attempt to highlight the different forms of material and symbolic (re)creation of Paris being undertaken today. We show that in a situation such as this, a reflection on the fieldwork undertaken and the production of ethnographic knowledge is in fact the key factor in the analysis.

Urban agriculture (UA) is spreading across vacant and marginal land worldwide, embraced by government and civil society as source of food, ecosystems services and jobs, particularly in times of economic crisis. ‘Metabolic rift' is an effective framework for differentiating UA's multiple origins and functions across the Global North and South. I examine how UA arises from three interrelated dimensions of metabolic rift—ecological, social and individual. By rescaling production, reclaiming vacant land and ‘de-alienating’ urban dwellers from their food, UA also attempts to overcome these forms of rift. Considering all three dimensions is valuable both for theory and practice.

A number of recent studies have used surveys of neighborhood informants and direct observation of city streets to assess aspects of community life such as collective efficacy, the density of kin networks, and social disorder. Raudenbush and Sampson (1999a) have coined the term “ecometrics” to denote the study of the reliability and validity of such assessments. Random errors of measurement will attenuate the associations between these assessments and key outcomes. To address this problem, some studies have used empirical Bayes methods to reduce such biases, while assuming that neighborhood random effects are statistically independent. In this paper we show that the precision and validity of ecometric measures can be considerably improved by exploiting the spatial dependence of neighborhood social processes within the framework of empirical Bayes shrinkage. We compare three estimators of a neighborhood social process: the ordinary least squares estimator (OLS), an empirical Bayes estimator based on the independence assumption (EBE), and an empirical Bayes estimator that exploits spatial dependence (EBS). Under our model assumptions, EBS performs better than EBE and OLS in terms of expected mean squared error loss. The benefits of EBS relative to EBE and OLS depend on the magnitude of spatial dependence, the degree of neighborhood heterogeneity, as well as neighborhood's sample size. A cross-validation study using the original 1995 data from the Project on Human Development in Chicago Neighborhoods and a replication of that survey in 2002 show that the empirical benefits of EBS approximate those expected under our model assumptions; EBS is more internally consistent and temporally stable and demonstrates higher concurrent and predictive validity. A fully Bayes approach has the same properties as does the empirical Bayes approach, but it is preferable when the number of neighborhoods is small.

Ordinary kriging, a spatial interpolation technique, is commonly used in social sciences to estimate neighborhood attributes such as physical disorder. Universal kriging, developed and used in physical sciences, extends ordinary kriging by supplementing the spatial model with additional covariates. We measured physical disorder on 1,826 sampled block faces across four U.S. cities (New York, Philadelphia, Detroit, and San Jose) using Google Street View imagery. We then compared leave-one-out cross-validation accuracy between universal and ordinary kriging and used random subsamples of our observed data to explore whether universal kriging could provide equal measurement accuracy with less spatially dense samples. Universal kriging did not always improve accuracy. However, a measure of housing vacancy did improve estimation accuracy in Philadelphia and Detroit (7.9 percent and 6.8 percent lower root mean square error, respectively) and allowed for equivalent estimation accuracy with half the sampled points in Philadelphia. Universal kriging may improve neighborhood measurement.

Cellphones provide a unique opportunity to examine how new media both reflect and affect the social world. This study suggests that people map their understanding of common social rules and dilemmas onto new technologies. Over time, these interactions create and reflect a new social landscape. Based upon a year-long observational field study and in-depth interviews, this article examines cellphone usage from two main perspectives: how social norms of interaction in public spaces change and remain the same; and how cellphones become markers for social relations and reflect tacit pre-existing power relations. Informed by Goffman's concept of cross talk and Hopper's caller hegemony, the article analyzes the modifications, innovations and violations of cellphone usage on tacit codes of social interactions.

Four urban public spaces, representing various designs and microclimates, were investigated in Gothenburg, Sweden, in order to estimate how weather and microclimate affect people in urban outdoor environments. The research strategy was both multidisciplinary and interdisciplinary and included scientists from three disciplines: architecture, climatology and psychology. The project is based on common case studies carried out during four seasons, including measurements of meteorological variables, interviews and observations of human activity at each place. Multiple regression analysis of meteorological and behavioural data showed that air temperature, wind speed and clearness index (cloud cover) have a significant influence on people’s assessments of the weather, place perceptions and place-related attendance. The results support the arguments in favour of employing climate sensitive planning in future urban design and planning projects, as the physical component of a place can be designed to influence the site-specific microclimate and consequently people’s place-related attendance, perceptions and emotions.

People's engagement with public open spaces is complex and affected by different factors. The importance of people's needs differs according to their age groups. In this respect, what this article aims to unveil is the priority of needs in public open spaces across age groups. A self-administered questionnaire survey collected the opinions of 400 people aged 13 years and above using the time-interval sampling method. The results revealed that the strongest inverse relationship existed between age and social needs. This illustrated that old people are less likely to carry out social interaction with other groups or to explore public open spaces compared to younger people. In turn, old people are more concerned about their physical and environmental needs. Exploring the dichotomies between the needs of old and young people highlights the intergenerational conflicts that challenge urban designers and decision makers to ameliorate the design and management of future public open spaces.

This paper examines intermediate, semi-enclosed urban spaces and investigates the potential creation of environmental diversity when such spaces are integrated in urban design. More specifically, it focuses on the links between architectural characteristics of semi-enclosed spaces and their thermal performance. The paper identifies major types of semi-enclosed spaces and monitors their thermal performance in northern and southern Europe. The results showed that a wide range of thermal conditions, namely cooler conditions during summer and warmer conditions during winter can be experienced in both regions. Moreover, the thermal variation, which was identified, is linked with the spatial identity of each space and it is argued that the degree of enclosure as well as the orientation and the urban context are significant temperature determinants. Intermediate, semi-enclosed urban spaces should be regarded as important urban components that could increase the thermal and spatial diversity of the urban fabric and therefore contribute to a more fulfilling and comfortable environment.

This study examined what factors best predict residents’ concerns about neighborhood safety. One-hundred and twenty-two participants were selected from a large, Midwestern metropolitan area. All participants lived in high crime areas. Participants completed a 22-item questionnaire that assessed their perceptions of neighborhood safety and vigilance. These items were clustered as: 1) Community care and vigilance, 2) neighborhood safety concerns, 3) physical incivilities, and 4) social incivilities. Police crime data were also used in the analyses. Our findings suggest that aspects of the broken window theory, collective efficacy, and place attachments/territoriality play a role in affecting residents’ concerns about neighborhood safety.

The article focuses on the relationship between street vendors and local authorities in Bangkok. We examine the goals, the means, and the effects of everyday regulation of street vending. We document how the district administration produces and maintains informality by creating a parallel set of rules where street vendors enjoy negligible rents and little competition. We provide detailed empirical evidence on earnings, rents, fines, and rules regarding commercial real estate. The district administration’s policy of “managed informality” results in a situation where more established informal vendors control less established ones. We hypothesize in the conclusion that the district administration’s parallel legal system adjusts to the population’s expectations in a political system where the law has little popular support.

The development and proliferation of mobile social networks have the potential to transform ways that people come together and interact in public space.These services allow new kinds of information to flow into public spaces and, as such, can rearrange social and spatial practices. Dodgeball is used as a case study of mobile social networks. Based on a year-long qualitative field study, this article explores how Dodgeball was used to facilitate social congregation in public spaces and begins to expand our understanding of traditional notions of space and social interaction. Drawing on the concept of parochial space, this article examines how ideas of mobile communication and public space are negotiated in the everyday practice and use of mobile social networks.

The focus of this paper is the strategies of civic actors in a central Tokyo neighborhood to claim a voice in managing changes to their community and creating shared meanings for neighborhood streets and public spaces. In Yanaka an active community movement has worked to protect and improve shared community spaces by celebrating them as a historic legacy and a shared community resource, investing new and more complex values and claims on shared spaces, and redefining public streets as civic spaces in their neighborhood. They assert the rights of community participation in managing urban change by creating a neighborhood constitution, organizing art events and festivals in the streets, engaging new participants in shared property rights, proposing new criteria for evaluating urban change, and telling stories of a strong and distinct community. Claiming ownership of the meaning and management of local public spaces is a political strategy of self empowerment by community groups that has been relatively successful in this case.

What is the Internet doing to local community? Analysts have debated about whether the Internet is weakening community by leading people away from meaningful in-person contact; transforming community by creating new forms of community online; or enhancing community by adding a new means of connecting with existing relationships. They have been especially concerned that the globe-spanning capabilities of the Internet can limit local involvements. Survey and ethnographic data from a “wired suburb” near Toronto show that high-speed, always-on access to the Internet, coupled with a local online discussion group, transforms and enhances neighboring. The Internet especially supports increased contact with weaker ties. In comparison to nonwired residents of the same suburb, more neighbors are known and chatted with, and they are more geographically dispersed around the suburb. Not only did the Internet support neighboring, it also facilitated discussion and mobilization around local issues.

Using a narrative methodology involving 216 older people in six urban aging environments in the Netherlands, we examined how they use and experience (semi-)public spaces as spaces of encounter, and the meanings they derive from using and experiencing these spaces. The research shows that, first, older people prefer commercial spaces like shopping malls to planned and designed activity spaces in care homes or neighborhood centers. Second, older people struggle with the transformations that have taken place in urban social life since they were young adults. Third, especially frail older people derive meaning from a more passive experience of urban social life, in an observer role. The findings allow us to contribute to ongoing debates on the shifting boundaries between public and private space, and the moral implications of these shifting boundaries from the perspective of a diverse group of older users.

Fear of crime is one of the most important problems in our cities, even in low-crime rate areas. The aim of this paper is to provide evidence of the issues involved in the perceived risk of victimization and fear of crime in these contexts using the Structural Equation Model (SEM) technique. Five hundred and seventy- one people living in a working-class neighborhood of Barcelona answered a 45-item questionnaire including the following 7 constructs: perception of insecurity, previous threat experiences, social representations of insecurity, personal control and coping skills, potential aggressors, urban identity, and perceived environmental quality. Findings confirm the theoretical model, in which fear of crime is structurally related to: a) environmental features, b) personal variables, and c) social representation of unsafe places. In addition, we found that the role of social aspects is as important as that of environ- mental and psychological ones. Residential satisfaction and urban social identity appear as relevant variables.

This article examines cultural practices and social life in urban public spaces of postreform China, focusing on the everyday leisure, entertainment, and cultural activities spontaneously organized by grassroots residents or groups. It examines performativity in constituting cultural meanings, reproducing everyday identities, and building up mutual engagements, and unravels the ways in which ordinary people devote resources, labor, and energy to keep alive individual or collective identities. Performances of cultural identities in public spaces entail improvised and temporary social relations which emerge from the immediate contexts of mundane spatial practices. Empirical analyses of public performativity in Guangzhou identify three scenarios, namely, the performativity of public teaching, public shows and performances, and the performative displays of cultural difference between carnivalesque dancing and “high-end culture” in public leisure.

This paper presents a comparative case study of two northern suburbs in Melbourne, Australia, in order to analyze local perceptions of proximity, mobility, and spaces of community interaction within diverse neighborhoods experiencing socioeconomic and demographic transition. We first look at government policies concerning the two suburbs, which position one suburb within a narrative of gentrification and the other within a narrative of marginalization. We then draw on diverse residents’ experiences and perceptions of local space, finding that these “everyday geographies” operate independently of and often at odds with local policy narratives of demographic and socioeconomic transition. We conclude that residents’ “everyday geographies” reveal highly varied and contested experiences of sociospatial dimensions of local change, in contrast to policy narratives that are often neoliberally framed.
