While aerial photography is associated with vertical objectivity and spatial abstractions, street-level imagery appears less political in its orientation to the particularities of place. I contest this assumption, showing how the aggregation of street-level imagery into “big datasets” allows for the algorithmic sorting of places by their street-level visual qualities. This occurs through an abstraction by “datafication,” inscribing new power geometries onto urban places through algorithmic linkages between visual environmental qualities, geographic information, and valuations of social worth and risk. Though largely missing from media studies of Google Street View, similar issues have been raised in critiques of criminological theories that use place as a proxy for risk. Comparing the Broken Windows theory of criminogenesis with big data applications of street-level imagery informs a critical media studies approach to Google Street View. The final section of this article suggests alternative theoretical orientations for algorithm design that avoid the pitfalls of essentialist equations of place with social character.

The collection of large-scale administrative records in electronic form by many cities provides a new opportunity for the measurement and longitudinal tracking of neighborhood characteristics, but one that will require novel methodologies that convert such data into research-relevant measures. The authors illustrate these challenges by developing measures of “broken windows” from Boston’s constituent relationship management (CRM) system (aka 311 hotline). A 16-month archive of the CRM database contains more than 300,000 address-based requests for city services, many of which reference physical incivilities (e.g., graffiti removal). The authors carry out three ecometric analyses, each building on the previous one. Analysis 1 examines the content of the measure, identifying 28 items that constitute two independent constructs, private neglect and public denigration. Analysis 2 assesses the validity of the measure by using investigator-initiated neighborhood audits to examine the “civic response rate” across neighborhoods. Indicators of civic response were then extracted from the CRM database so that measurement adjustments could be automated. These adjustments were calibrated against measures of litter from the objective audits. Analysis 3 examines the reliability of the composite measure of physical disorder at different spatiotemporal windows, finding that census tracts can be measured at two-month intervals and census block groups at six-month intervals. The final measures are highly detailed, can be tracked longitudinally, and are virtually costless. This framework thus provides an example of how new forms of large-scale administrative data can yield ecometric measurement for urban science while illustrating the methodological challenges that must be addressed.

Increasing amounts of information processing capacity are embedded in the environment around us. The informational landscape is both a repository of data and also increasingly communicates and processes information. No longer confined to desk tops, computers have become both mobile and also disassembled. Many everyday objects now embed computer processing power, while others are activated by passing sensors, transponders and processors. The distributed processing in the world around us is often claimed to be a pervasive or ubiquitous computing environment: a world of ambient intelligence, happening around us on the periphery of our awareness, where our environment is not a passive backdrop but an active agent in organizing daily lives. The spaces around us are now being continually forged and reforged in informational and communicative processes. It is a world where we not only think of cities but cities think of us, where the environment reflexively monitors our behaviour. This paper suggests that we need to unpack the embedded politics of this process. It outlines the three key emerging dynamics in terms of environments that learn and possess anticipation and memory, the efficacy of technological mythologies and the politics of visibility. To examine the assumptions and implications behind this the paper explores three contrasting forms of ‘sentient’ urban environments. The first addresses market-led visions of customized consumer worlds. The second explores military plans for profiling and targeting. Finally, the third looks at artistic endeavours to re-enchant and contest the urban informational landscape of urban sentience. Each, we suggest, shows a powerful dynamic of the environment tracking, predicting and recalling usage.

An entire category of urban space, albeit hardly recognized as such, is disappearing across North America. As retail logistics globalizes and big-box power centres replace enclosed shopping malls from the postwar era, a distinct form of social infrastructure vanishes as well. ‘Dead malls’ are now a staple of North American (sub)urban landscapes, and have provoked local activism in many places. But despite popular concern for the demise of mall space, critical urban scholarship has largely sidelined the phenomenon. Much of the disjuncture between popular outcry and academic silence relates to conceptions of ‘public’ space, and specifically the gap between formal ownership and everyday spatial practice. Spatial practice often exceeds the conceptions of designers and managers, transforming malls into community space. This is particularly true in declining inner suburbs, where poor and racialized communities depend more heavily on malls for social reproduction as well as recreation and consumption. In this article we investigate the revolution in logistics that has provoked the phenomenon of ‘dead malls’ and the creative activism emerging that aims to protect mall space as ‘community space’. Taking the case of the Morningside Mall in an old suburb of Toronto, we investigate the informal claims made on mall space through everyday spatial practice and the explicit claims for community space that arise when that space is threatened. We argue that many malls have effectively become community space, and activism to prevent its loss can be understood as a form of anti-globalization practice, even if it never employs that language.

The current deployment of large screens in city centre public spaces requires a substantial rethinking of our understanding of the relationship of media to urban space. Drawing on a case study of the Public Space Broadcasting project launched in the UK in 2003, this article argues that large screens have the potential to play a significant role in promoting public interaction. However, the realization of this potential requires a far-reaching investigation of the role of media in the construction of complex public spaces and diverse public cultures.

This paper begins by reviewing a range of recent work by geographers conceptualising buildings less as solid objects and more as performances. Buildings, it is argued, are not given but produced, as various materials are held together in specific assemblages by work of various kinds. This has led to a range of studies looking at the diverse sorts of work that make buildings cohere: the political institutions they are embedded in, the material affordances of their non-human components, the discourses surrounding particular kinds of buildings, and, in particular, the experiencing of buildings by their human inhabitants, users and visitors. However, this experiencing has been poorly theorised. Those geographers inspired by actor network approaches to buildings acknowledge human experiences, but in very limited ways; while those geographers inspired more by affect theory evoke the 'feelings' that buildings may provoke but evacuate human subjectivity from their accounts of buildings' performances. Through a case study of two buildings, this paper argues that both approaches are flawed in their uninterest in the human, and proposes that more attention be paid to (at least) three aspects of human feeling: the feel of buildings, feelings in buildings and feelings about buildings.

In this article we aim to utilise and apply ethnomethodological and interactionist principles to the analysis of members’ situated accounts of regenerated urban space. With reference to previous empirical studies we apply membership categorization analysis and the concept of mundane reason to data gathered from situated street level interviews carried out as part of a programme of ethnographic research into the regenerated setting of Cardiff Bay. The article demonstrates that these data yield sociological insight into social actors’ interpretive and interactional reasoning in relation to the negotiation, navigation and comprehension of space and place. Through this work the patterned signatures of the urban interactional order can be identified. Furthermore, we illustrate the forms of emic rationality associated with the everyday and ubiquitous constitution of urban space as a meaningful, and thence cultural, milieu. It is our claim that an appreciation of these urban forms of reasoning is important in the ethnographic, sociological and geographical analysis of space and place.

Since the early 2000s, the proliferation of cameras, whether in mobile phones or CCTV, led to a sharp increase in visual recordings of human behavior. This vast pool of data enables new approaches to analyzing situational dynamics. Application is both qualitative and quantitative and ranges widely in fields such as sociology, psychology, criminology, and education. Despite the potential and numerous applications of this approach, a consolidated methodological frame does not exist. This article draws on various fields of study to outline such a frame, what we call video data analysis (VDA). We discuss VDA’s research agenda, methodological forebears, and applications, introduce an analytic tool kit, and discuss criteria for validity. We aim to establish VDA as a methodological frame and an interdisciplinary analytic approach, thereby enhancing efficiency and comparability of studies, and communication among disciplines that employ VDA. This article can serve as a point of reference for current and future practitioners, reviewers, and interested readers.

Critics have long denounced the design of suburban communities for fostering political apathy. We disaggregate the concept of suburban design into four distinct attributes of neighborhoods. We then use tract-level Census data, the Social Capital Community Benchmark Survey, and multilevel models to measure the relationship between these design features and political participation. Certain design aspects common in suburban neighborhoods are powerful predictors of reduced political activity, illustrating a potential link between neighborhood design and politics. Yet low-density environments appear to facilitate some types of participation. Suburban designs vary, and so do their likely impacts on political participation.

Public markets were once essential parts of the cityscape and they are becoming so again. Markets serve several purposes, social, political, and economic, and so planners interested in multipurpose tools for development will be interested in public markets. Markets can help achieve a variety of goals including place-making, employment, and entrepreneurship. This article focuses on markets as tools of business incubation. Archival data and literature shows how important markets once were to cities. Ethnographically collected data from Chicago's Maxwell Street market illustrates the individual and structural factors that account for businesses created at the market. Rural and urban markets are emerging or being rehabilitated all over the country — this research helps planners understand the history of markets, their multi-disciplinary nature, and the circumstances of people creating businesses at markets.

The promotion of quality of life is becoming ever more important in a scenario of regional, national and even international competition among cities, triggered by globalization. Public sites, and green spaces in particular, which are available in varying extent in all urban areas, can bring important benefits to urban vitality and, as a consequence, to quality of life. However, cities are intricate entities and measuring their success in converting the potential for public green space usage into increased quality of life is a difficult task. In order to contribute to the objective of assessing the potential for public green space use, and its consequences on urban vitality, we applied the Data Envelopment Analysis technique to assess a total of 174 European cities. The results detect the best performing cities, and for the cities considered inefficient, a set of benchmarks is identified, whose best practices can be copied to support efforts of performance improvement.

This paper draws upon a model of the publicness of publicly owned and managed spaces by means of fuzzy logic modelling. The value of this approach is that it is practical in simplifying and emphasizing both the interdependent nature of the concept of publicness and its complexity. The proposed model aims to effectively evaluate and compare the publicness of public space. The paper highlights different methodologies in understanding this publicness by considering various conceptual approaches at the heart of the debate about public space. In doing so, the paper is organized into four main parts. The first part considers the complex and fuzzy nature of the concept. The second presents the proposed model of publicness based on management, access and user dimensions by analyzing the leading discourse and previous models of publicness. The third part draws upon research methodology and fuzzy logic modelling, and the fourth part explains the findings of the case study in Istanbul.

The rise of mobile food vending in US cities combines urban space and mobility with continuous online communication. Unlike traditional urban spaces that are predictable and known, contemporary vendors use information technology to generate impromptu social settings in unconventional and often underutilized spaces. This unique condition requires new methods that interpret online communication as a critical component in the production of new forms of public life. We suggest qualitative approaches combined with data-driven analyses are necessary when planning for emergent behavior. In Charlotte, NC, we investigate the daily operations, tweet content, and spatial and temporal sequencing of six vendors over an extended period of time. The study illustrates the interrelationship between data, urban space, and time and finds that a significant proportion of tweet content is used to announce vending locations in a time-based pattern and that the spatial construction of events is often independent of traditional urban form.

In this article, we extend research on neighborhood social isolation by (1) examining residents of disadvantaged and advantaged communities and (2) considering the character of neighborhoods where people conduct routine activities away from home. We contend that social isolation is experienced by residents of both highly disadvantaged and highly advantaged neighborhoods because the two groups spend time in largely nonoverlapping parts of the city. Individual and neighborhood race-ethnic dynamics exacerbate such social isolation. Data from the Los Angeles Family and Neighborhood Survey show that social isolation is experienced by residents of all areas of the city, whether highly disadvantaged or advantaged. African Americans, Latinos and residents of areas with many Latinos suffer additional penalties in the social isolation of disadvantage in where they conduct routine activities.

To what extent does the density of the tree cover in a city relate to the amount of social capital among neighbors? To address this question, we linked social survey data (N = 361) from the Baltimore Ecosystem Study with socioeconomic, urban form, and green space data at the census block group level using a geographic information system. We found a systematically positive relationship between the density of urban tree canopy at the neighborhood block group level and the amount of social capital at the individual level (r = .241, p < .01). Multiple regression analyses showed that tree canopy added a 22.72% increase in explanatory power to the model for social capital. This research adds a new variable—neighborhood tree canopy—to the typologies of green space that affect human social connection. Trees are a relatively inexpensive and easy intervention to enhance the strength of social ties among neighbors.

Recent critiques of conventional poverty research have highlighted the need to move beyond the conceptual limitations of “neighborhood effects” models and the use of the tropes of “adaptation” or “resistance” to explain the behaviors and actions of the urban poor. We use ethnographic field observations and interviews with public-housing residents to address these limitations in the poverty literature, assess competing explanations of poor people’s agency, and provide insight into the importance of space as a mediating link between macrostructural constraints and locally situated behaviors. We theorize agency and identity as spatial phenomena—with spatial attributes and spatial influences—and examine how different spatial meanings and locations enable or constrain particular forms of social action and behavior. Our ethnographic and interview data depict several strategies by which residents “use space” to provide a measure of security and protection, to designate and avoid areas of criminality and drug activity, and to challenge or support the redevelopment of public housing. From these data we show that urban space is not a residual phenomenon in which social action occurs, but a constitutive dimension of social life that shapes life experiences, social conflict, and action.

Most theoretical perspectives on neighborhood effects on youth assume that neighborhood context serves as a source of socialization. The exact sources and processes underlying adolescent socialization in disadvantaged neighborhoods, however, are largely unspecified and unelaborated. This article proposes that cross-cohort socialization by older neighborhood peers is one source of socialization for adolescent boys. Data from the National Educational Longitudinal Survey suggest that adolescents in disadvantaged neighborhoods are more likely to spend time with older individuals. I analyze qualitative interview data from 60 adolescent boys in three neighborhoods in Boston to understand the causes and consequences of these interactions and relationships. Some of the strategies these adolescents employ to cope with violence in disadvantaged neighborhoods promote interaction with older peers, particularly those who are most disadvantaged. Furthermore, such interactions can expose adolescents to local, unconventional, or alternative cultural models.

Urban sociologists and criminologists have maintained housing’s importance in providing individuals with a sense of security within their neighborhood. Yet it remains unclear whether all types of housing provide this sense of safety in the same way. This article provides an analysis of the relationship between dwelling type and fear of crime. Data from the 2009 Canadian General Social Survey are analyzed. Results suggest that living in a multiunit dwelling has no statistically significant impact on fear of crime in the neighborhood; however, individuals living in high-rise and low-rise residences are less likely to be fearful of crime while at home in the evening. One possible explanation for these findings is the fortress effect: High-rise buildings isolate individuals in physical space, providing security in the home, and creating physical and social distance from the rest of the neighborhood. The implications of these findings are discussed.

This article illustrates how spatial/cultural representations come into being with data collected during a 7-month ethnographic study of two plazas, the Parque Central and the Plaza de la Culture in San José, the capital city of Costa Rica. The comparison of their history, physical and spatial symbolism, user activities and daily behaviors, and news reports and commentaries demonstrates how these cultural representations reflect meanings that change in response to the material conditions and social values of the historical period. Further, the analysis uncovers that moral contradictions in those meanings are expressed first in the traditional plaza setting, and then, are transformed into contradictions across both plazas.
