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.

This article assesses the sources and consequences of public disorder. Based on the videotaping and systematic rating of more than 23,000 street segments in Chicago, highly reliable scales of social and physical disorder for 196 neighborhoods are constructed. Census data, police records, and an independent survey of more than 3,500 residents are then integrated to test a theory of collective efficacy and structural constraints. Defined as cohesion among residents combined with shared expectations for the social control of public space, collective efficacy explains lower rates of crime and observed disorder after controlling neighborhood structural characteristics. Collective efficacy is also linked to lower rates of violent crime after accounting for disorder and the reciprocal effects of violence. Contrary to the “broken windows” theory, however, the relationship between public disorder and crime is spurious except perhaps for robbery.

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 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.

Research shows that social relations within a space and the group(s) who control that space socially have a greater influence on how safe women feel than does the design of the space. And more action and research is needed to investigate how men dominate space and how this dominance can be broken.

Records on recovery after cholecystectomy of patients in a suburban Pennsylvania hospital between 1972 and 1981 were examined to determine whether assignment to a room with a window view of a natural setting might have restorative influences. Twenty-three surgical patients assigned to rooms with windows looking out on a natural scene had shorter postoperative hospital stays, received fewer negative evaluative comments in nurses' notes, and took fewer potent analgesics than 23 matched patients in similar rooms with windows facing a brick building wall.

This article focuses on the dynamics between migrant street vendors and public security forces and the complex social production of urban public space in Guangzhou. As an answer to daily contestation of public order, security agencies reluctantly open flexible windows of business opportunities to hawkers. Zones and periods of control, ‘soft’ approaches, and categories of ethnic belonging influence everyday governance and accessibility of public space. This results in a transient public space, fluid and continuously changing, which offers a new perspective on openness and functioning of public space in urban China.

The objective was to investigate associations between features of the physical environment and neighborliness. Measures of the physical environment, including sidewalks, front porches, traffic-calming devices, bars on windows, and the presence of litter or graffiti, were collected using a systematic audit instrument in 10 neighborhoods in Portland, Oregon. Generalized linear regression models were created to model the odds of increasing neighborliness given access to the physical-environment factors of interest. The authors observed a greater probability of higher levels of neighborliness as the total number of positive physical-environment characteristics increased (cumulative odds ratio [95% confidence interval] = 1.69 [1.16, 2.45]) and the results were unchanged after controlling for race, self-reported health, perception of safety, years of neighborhood residence, age of house, market value of house, and proportion of homeowners in neighborhood. Modifiable features of the physical environment may be one mechanism through which people can enhance neighborliness.

By measuring twenty streetscape features and numerous other variables for 588 blocks in New York City, we were able to identify variables that explain pedestrian traffic volumes. We found significant positive correlations between three out of twenty streetscape features with pedestrian counts after controlling for density and other built environmental variables. The significant streetscape features are the proportion of windows on the street, the proportion of active street frontage, and the number of pieces of street furniture. This study provides guidance for streetscape projects that aim to create walkable streets and pedestrian-friendly environments.

This study examines a behavioral model using latent variables of leisure involvement, place attachment, and destination loyalty among recreationists walking their dog in urban parks. A total of 928 usable questionnaires were collected. The confirmatory factor analysis and structural equation modeling were analyzed using LISREL 8.70 for Windows. Empirical results indicate that leisure involvement (i.e., attraction and self expression) and place attachment (i.e., place identity and place dependence) accurately predict the destination loyalty of recreationists walking their dogs in urban parks. Findings of this study demonstrate that the proposed behavioral model is a highly effective means of examining the causal relationships among leisure involvement, place attachment, and destination loyalty. A series of managerial implications and recommendations for further studies are drawn.

Over the last 30 years, social theorists have increasingly emphasized the importance of space. However, in empirical research, the dialectical relationship between social interaction and the physical environment is still a largely neglected issue. Using the theory of structuration, I provide a concrete example of why and how space matters in the cultural analysis of an urban social world. I argue that bike messengers—individuals who deliver time-sensitive materials in downtown cores of major cities—cannot be understood outside an analysis of space. Specifically, I connect the cultural significance of messenger practices to the emplacement of those practices inside the urban environment.

This paper proposes an essentially new theory of urban space based on information theory and the laws of optics. The use of urban space is linked to the information field generated by surrounding surfaces, and on how easily the information can be received by pedestrians. Historical building exteriors usually present a piecewise concave, fractal aspect, which optimizes visual and acoustical signals that transmit information content. Successful urban spaces also offer tactile information from local structures meant for standing and sitting. The total information field in turn determines the optimal positioning of pedestrian paths and nodes. This complex interaction between human beings and the built environment, incredibly neglected in our times, explains why so many historical urban spaces provide an emotionally nourishing environment.

This paper develops an analytical framework to place the rise of open source urbanism in context, and develops the concept of the ‘right to infrastructure’ as expressive of new ecologies of urban relations that have come into being. It describes, first, a genealogy for open source technology, focusing in particular on how open source urban hardware projects may challenge urban theory. It moves then to describe in detail various dimensions and implications of an open source infrastructural project in Madrid. In all, the paper analyses three challenges that the development of open source urban infrastructures is posing to the institutions of urban governance and property: the evolving shape and composition of urban ecologies; the technical and design challenges brought about by open source urban projects; and the social organisation of the ‘right to infrastructure’ as a political, active voice in urban governance. In the last instance, the right to infrastructure, I shall argue, signals the rise of the ‘prototype’ as an emerging figure for contemporary sociotechnical designs in and for social theory.

In the last ten years environmental sociologists have started to explore the relations between human behavior and the physical environment. This study tests some of the ideas of Jane Jacobs on how neighboring and crime are affected by physical diversity in cities. While neighboring and crime are found to be related to diversity as defined by Jacobs, neighboring is not related to crime, which is also predicted by her theory. The implications for urban planning are considered.

Safety from crime in multifamily housing environments, where residents usually share hallways, common outdoor facilities, and parking spaces, has been a subject of research for decades. Strategies and tactics employed to enhance the safety of these environments may differ depending on residents' characteristics. This study explored residents' perceived and actual safety in multifamily environments in the United States and South Korea, as well as significant environmental variables. Using Newman's defensible space theory as the primary theoretical framework, we focused on how perceived safety in public and semipublic spaces relates to overall perceptions of safety in residential environments. We also examined crime experience in these environments and verified significant demographic and socioeconomic variables associated with residents' perceptions of safety. Data were collected from site visits and questionnaires administered to residents living in multifamily environments. The level of residents' safety perceptions differed between the two groups of residents. However, both groups exhibited strong correlations between perceived safety from crime in their communities and perceived safety in public spaces, such as recreational areas and parking lots, and semipublic spaces, such as building entrances and the vicinity. These findings underscore strong relationships among residents' perceptions of safety in different outdoor spaces, which the defensible space theory also supports. Based on these findings, we suggest ideas to improve residents' actual safety and perceptions of safety from crime.

Women's use of public space has been the subject of much recent research. Existing theory in environment-behavior studies is inadequate to explain these findings. This paper proposes the adoption of the feminist theory of the 'ethic of care' to synthesize and explain much existing research on women's experience of public space. The ethic of care is a model of moral development in which the highest moral imperative requires taking care of needs and sustaining relationships. This paper examines how the ethic of care creates constraints for women's use of public space, by encouraging women to put others first and by reinforcing women's primary responsibility for care-giving. The ethic of care constrains women's use of public space through the association of women with low status `caring' occupations, and through actions that extend restrictive caring to women. At the same time, through women's use of public space, the ethic of care generates possibilities for women to give and receive care from others and themselves, and creates possibilities for extending care to encompass public spaces. The ethic of care is explored in detail in light of two areas of environment-behavior research on women and public spaces: preference and fear of crime. In conclusion, the paper advocates the ethic of care as a framework for future activism, design, and scholarship concerning public spaces.

Within the International debates about the roles and relevance of planning and architecture, urban design is trying to find its place and clarify its contribution to city making. The products and the practice of urban design vary significantly in different global and socio-economic contexts and in relation to varying theoretical foundations. In South Africa, as in other developing countries, urban design is only beginning to feature as a valid mainstream concern within city development and among built environment practitioners. This paper presents the case of the City of Cape Town’s Dignified Places Programme as an example of implementation-focused urban design undertaken in a context where the conscious design and management of the public realm does not feature on the agendas of cash-strapped, basic needs-focused local government. The design and construction of new public spaces is the focus of this programme, but a parallel objective is to place the central concern of urban design – the quality of the public environment – squarely on the agenda of local government in Cape Town. The paper outlines the urban context in which it is being implemented sketches the issues that prompted its initiation and traces its theoretical origins focusing on the linkages between this theory and practice. The paper gives an account of the origins, objectives and strategy as well as the design principles that directed the form and location of the projects in the Programme. The paper finally reflects on the key successes and challenges of the programme and attempts to tease out lessons for both the theory and practice of urban design.

Despite the fact that virtual environments are increasingly deployed to study the relation between urban planning, physical and social disorder, and fear of crime, their ecological validity for this type of research has not been established. This study compares the effects of similar signs of public disorder (litter, warning signs, cameras, signs of vandalism and car burglary) in an urban neighborhood and in its virtual counterpart on the subjective perception of safety and livability of the neighborhood. Participants made a walking tour through either the real or the virtual neighborhood, which was either in an orderly (baseline) state or adorned with numerous signs of public disorder. During their tour they reported the signs of disorder they noticed and the degree to which each of these affected their emotional state and feelings of personal safety. After finishing their tour they appraised the perceived safety and livability of the environment. Both in the real and in the simulated urban neighborhood, signs of disorder evoked associations with social disorder. In all conditions, neglected greenery was spontaneously reported as a sign of disorder. Disorder did not inspire concern for personal safety in reality and in the virtual environment with a realistic soundscape. However, in the absence of sound disorder compromised perceived personal safety in the virtual environment. Signs of disorder were associated with negative emotions more frequently in the virtual environment than in its real-world counterpart, particularly in the absence of sound. Also, signs of disorder degraded the perceived livability of the virtual, but not of the real neighborhood. Hence, it appears that people focus more on details in a virtual environment than in reality. We conclude that both a correction for this focusing effect and realistic soundscapes are required to make virtual environments an appropriate medium for both etiological (e.g. the effects of signs of disorder on fear of crime) and intervention (e.g. CPTED) research.

Recent debates around urban encounter, integration cosmopolitanism, and renewed engagement with contact theory have raised questions about the spaces of interaction that may enable meaningful encounters between different social groups. Reflecting on a participatory art project with young people of African and British heritage in northeast England, we argue that discussion and practice around participatory action research, including the deployment of contact zones as theory and method, can cast some light on what fosters transformative spaces. Through analysis of two different approaches to community art used in the project, we show how elements of each enabled and disabled meaningful interaction between young people. We draw attention to the materiality of art (the tools) within participatory practices (the doing of it) in contributing to a space where interactions might take place, emphasising a complex interplay across/between actors, materials, and space that frames encounters as emergent, transitory, fragile, and yet hopeful. We examine the potential of a focus on the material in thinking beyond moments of encounter to how transformative social relations may be `scaled up' before considering the implications for research and policy.

This paper problematises public artopia, in other words the collection of claims in academic literature concerning the allegedly physical-aesthetic, economic, social, and cultural-symbolic roles of art in urban public space. On the basis of interviews with public-art producers (artists, public officials, investors, and participating residents) in a flagship and a community-art project in Amsterdam, we analyse the situatedness of their public-art claims according to actors’ roles, geographical context, and time. The research suggests that public-art theory and policy suffer from three deficiencies. Theoretical claims about public-art and policy discourse feature, first, a failure to recognise different actors’ perspectives: claims fail to locate situated knowledges that are intrinsically (re)constituted by actors’ roles articulating with one another in time and space. Second is the lack of geographical contextuality: claims do not elaborate appropriately on distinct discourses about art projects’ spatial settings. Third is the lack of temporal perspective. Claims neglect the practice of public-art realisation: that is, the evolution of claims and claim coalitions over the time horizon of the art projects: preparation, implementation, and evaluation.
