Foursquare is a location-based social network (LBSN) that allows people to share their location with friends by ‘checking-in’ at a given place using their smartphone. The application can also access the location-based recommendations left by other users. Drawing on original qualitative research with a range of Foursquare users, the article sets out to examine this LBSN and its impact on identity in three ways. Using Schwartz and Halegoua’s ‘spatial self’ as ‘a theoretical framework encapsulating the process of online self-presentation based on the display of offline physical activities’, the article first examines the extent to which users understand check-ins as mediating identity. Second, the article explores whether the act of using Foursquare beyond the sharing of location can similarly be seen as contributing to identity. Last, the article examines what effect location-based recommendations might be having on how users subsequently experience themselves.

Location-aware mobile media allow users to see their locations on a map on their mobile phone screens. These applications either disclose the physical positions of known friends, or represent the locations of groups of unknown people. We call these interfaces eponymous and anonymous, respectively. This article presents our classification of eponymous and anonymous location-aware interfaces by investigating how these applications may require us to rethink our understanding of urban sociability, particularly how we coordinate and communicate in public spaces. We argue that common assumptions made about location-aware mobile media, namely their ability to increase one’s spatial awareness and to encourage one to meet more people in public spaces, might be fallacious due to pre-existing practices of sociability in the city. We explore these issues in the light of three bodies of theory: Goffman’s presentation of self in everyday life, Simmel’s ideas on sociability, and Lehtonen and Mäenpää’s concept of street sociability.

Analysis of property sales in the vicinity of 1,294-acre Pennypack Park in Philadelphia indicates a statistically significant rise in land value with closeness to park, when allowance is made for effect of type of house, year of sale, and special characteristics such as location on corner of block. Location rent due to the park ranges from approximately $11,500 per acre 40 feet from the park to $1,000 at 2,500 feet. It accounts for 33 percent of land value at 40 feet, 9 percent at 1,000 feet, and 4.2 percent at 2,500 feet. Each acre of parkland may be said to generate a value of $2,600 in location rent.

As a growing number of social media platforms now include location information from their users, researchers are confronted with new online representations of individuals, social networks, and the places they inhabit. To better understand these representations and their implications, we introduce the concept of the “spatial self”: a theoretical framework encapsulating the process of online self-presentation based on the display of offline physical activities. Building on previous studies in social science, humanities, and computer and information science, we analyze the ways offline experiences are harnessed and performed online. We first provide an encompassing interdisciplinary survey of research that investigates the relationships between location, information technology, and identity performance. Then, we identify and characterize the spatial self as well as examine its occurrences through three case studies of popular social media sites: Instagram, Facebook, and Foursquare. Finally, we offer possible research directions and methodological considerations for the analysis of geocoded social media data.

This study examines how the availability of nature influences the use of outdoor public spaces in two Chicago public housing developments. Ninety-six observations were collected of the presence and location of trees and the presence and location of youth and adults in semiprivate spaces at one high-rise and one low-rise public housing development. Results consistently indicated that natural landscaping encourages greater use of outdoor areas by residents. Spaces with trees attracted larger groups of people, as well as more mixed groups of youth and adults, than did spaces devoid of nature. In addition, more dense groupings of trees and trees that are located close to public housing buildings attracted larger groups of people. These findings suggest that natural elements such as trees promote increased opportunities for social interactions, monitoring of outdoor areas, and supervision of children in impoverished urban neighborhoods.

High street shopping centres are at the core of cities. The continuing design challenge is to adapt a built environment inheritance to meet the present commercial needs of retailers, maximize the potential of the physical environment and address the social amenities that are expected from a city/town centre public realm. This paper addresses the question of what makes a successful high street shopping centre and seeks to understand the relationship between property values, location, physical characteristics, diversity of retailing and use, and social vitality in two successful city centre retailing environments. The research also demonstrates the blurring between commercial and public space, and supports Carmona’s argument that successful social space also creates economic value.

Through an ethnographic study of a stretch of beach in Rio de Janeiro's Copacabana and Ipanema neighborhoods, the author argues that the public space of the city can act as a sort of public sphere where the politics of everyday class and race interaction can be part of larger scale politics, even in a very divided city like Rio de Janeiro. But Rio's beaches only confer a sort of marginal citizenship on their users. They are not the location of discursive democracy idealized by some social theorists, nor are they the egalitarian classless and color-blind spaces mythologized by the Brazilian elite. Rather, they are the site of an unequal, often confrontational politics of class whereby the legitimacy of the social order is challenged, renegotiated, and ultimately reproduced.

This article addresses the tradeoff between the values households’ place on shared open space and parcel size, and the implications for housing development policy. Marginal implicit prices of shared open space and single-family housing parcel size are estimated using geographically weighted regression corrected for spatial autocorrela- tion. The marginal rate of substitution (MRS) of shared open space for lot size is calculated for individual households. Defining target areas based on site-specific MRSs could provide policy makers with more accurate information for designing or updating location-specific land use policies in efforts to moderate urban sprawl.

In recent years, a greater emphasis on user analysis and public participation in park planning has resulted in a greater scrutiny of the standards and guidelines used to establish and/or develop park areas within a community. The insensitivity of past "service area" approaches to meet the needs of neighborhood constituencies has created a demand to examine alternative approaches to defining neighborhood boundaries and the subsequent location of neighborhood parks. Two techniques that have been useful in accurately defining neighborhood boundaries and predicting use and nonuse of existing park facilities are examined.

This paper examines the relationship between space and the digital industries through everyday work practices in Shoreditch, London. Drawing on interviews with digital workers, the paper examines how work unfolds in multiple settings and how the built environment supports these work patterns. Digital work extends from the office or the residence (the base) to multiple settings (ancillary spaces) in what can be defined as an extended workplace. The study identifies micro and macro scale characteristics of the built environment that are relevant (spatial characteristics of semi-public and public spaces, access and control, location, and attributes of the neighbourhood) expanding the understanding of why and how place matters for these industries. A typology of ancillary spaces and some reflections on policy implications are advanced.

Public realm schemes are being introduced in urban areas without the usual delineation between the footway and carriageway provided by kerb edges. Concern has been expressed about the resulting spaces on behalf of the approximately two million people in the UK who are blind or visually impaired. This paper questions these concerns and presents the results from a questionnaire and in-depth interviews, and observational studies of blind and visually impaired people navigating in urban streets and spaces with and without shared surfaces. They show that blind and visually impaired people can identify many different surface types and delineators, and they use these, along with other features of the urban environment, in creative ways to identify their location and guide themselves. Shared Space schemes need to preserve a safe area for pedestrians, they need to provide a rich physical environment of contrasts in terms of surface tactility, colour contrast, and the enhancement of sound and other sensory clues.

This study compares community-park design and residents' perceptions of safety in two subdivision communities in The Woodlands, Texas. The communities were built following two different planning approaches—the ecological approach and the conventional approach. Surveys have shown that residents generally feel safer in community parks built according to the latter approach. Using landscape metrics and home-to-park proximity indicators, we examine how different planning approaches affect park design and, as a result, influence residents' perceptions of safety. We cross-validated the results with survey studies conducted over several years. The study findings suggest that park location, spatial configuration of woody vegetation, and management of understory can be important design considerations that impact residents' perceived levels of safety. Park designers and managers should also consider providing parks that meet diverse needs and balance the requirements of ecological preservation, aesthetics, and cultural preference.

Drawing on the social disorganization tradition and the social ecological perspective of Jane Jacobs, the authors hypothesize that neighborhoods composed of residents who intersect in space more frequently as a result of routine activities will exhibit higher levels of collective efficacy, intergenerational closure, and social network interaction and exchange. They develop this approach employing the concept of ecological networks—two-mode networks that indirectly link residents through spatial overlap in routine activities. Using data from the Los Angeles Family and Neighborhood Survey, they find evidence that econetwork extensity (the average proportion of households in the neighborhood to which a given household is tied through any location) and intensity (the degree to which household dyads are characterized by ties through multiple locations) are positively related to changes in social organization between 2000–2001 and 2006–2008. These findings demonstrate the relevance of econetwork characteristics—heretofore neglected in research on urban neighborhoods—for consequential dimensions of neighborhood social organization.

Urban design scholars denounce the recent trend towards the privatization of US public space. Critics emphasize the negative consequences of privatized public space, tied to private ownership, an emphasis on consumption, leisure and security, a targeted audience, and controlled behaviour and design. Yet these key qualities of privatized public spaces have meaning only in the context of one's identity. The same qualities shape experiences of privatized public spaces that can be understood as constrained, as constraining or as a form of resistance, depending on one's gender, race, class and sexuality. This paper challenges the prevailing design critique by examining women's experience of privatized public spaces, drawing on interviews with 43 middle- class women and behavioural mapping in five privatized public spaces in Orange County, California. Recommendations address changes to research and practice to better reflect and accommodate diverse experiences of public space.

This article deals with issues of territoriality, public space, the microphysics of power and street gang life in the current urban context of Kinshasa, capital of the Democratic Republic of Congo. In this city, a growing number of street children invade the public places. They team up in gangs and scour the streets in search of a location to settle (for a while). Along with their appropriation of public space, these gangs encounter several actors such as the city authorities, shop owners, tenants or rival street gangs. Before any settlement, deals have to be closed since every inch of the city is negotiable. All participants get involved in these negotiations, for no one is considered marginal, certainly not the street youth who are inextricably bound up with Congolese society. This contribution considers this dynamic field of negotiations through a focus on space and analyses it from a Foucauldian angle. It explores how gang members develop particular ways to control their territories and exercise power in them. Additionally, it examines how street youths manage to construct a home in the streets and make sense of their urban environment in the process.

This paper reports findings from recent research examining the relationship between urban design and layout and aspects of social and communal life in urban neighbourhoods. To address this, six UK neighbourhoods of varying densities and layouts were selected for detailed investigation. Data on social interactions, social activities and social networks along with perceptions of the built and social environment of the neighbourhoods were collected through observations, questionnaire surveys and secondary data sources. Neighbourhood design and layout were analysed using spatial network and visibility graph analysis methods. Correlation and multiple regression tests were conducted to test the claimed associations. Findings indicate differences between socializing patterns and structure of social networks in high- and low-density areas. Low-density areas were associated with widely spread social networks and activities with very few strong relationships. In high-density neighbourhoods, respondents had small networks but stronger ties were found. Detailed investigation shows that much of this can be attributed to, among other physical factors: the location of public spaces, visibility from and to these spaces, visual links between neighbourhoods', typology and physical form of development rather than density alone. This indicates that some of the negative social impacts found within high-density urban development might be rectified with better design of neighbourhoods. It is clear that to deliver sustainable development, the 'compact city' will have to be designed with specific spatial and built environment characteristics.

A lack of collective efficacy in neighborhood is associated with social and physical disorder and related anti-social actions. It is less clear, however, whether collective efficacy in neighborhood also enhances prosocial, other-regarding behavior. We studied this association by employing the Lost Letter Technique in a large-scale field experiment. Our data stem from 1,240 letters dropped in a representative sample of 110 Dutch neighborhoods, combined with neighborhood data based on a survey of residents (SSND2, n=996) and information provided by Statistics Netherlands. We distinguish between two conditions (1) location of the lost letter, that is, behind a car's windshield wiper on the sidewalk; and (2) type of addressee, that is, a Dutch name or a Turkish/Moroccan name. When we decompose collective efficacy into social cohesion and shared expectations of social control, we find that shared control expectations clearly matter for the rate of posted letters. Social cohesion has no effect. Furthermore, a high percentage of non-Western residents, high residential mobility, and a relatively low local income level are negatively related to the rate of posted letters.

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.

Art in public space in South Africa is increasingly a more visible locus of sociopolitical resistance and recalibration of the public sphere. This article focuses upon an emblematic example: the sculpture of a former colonialist, removed from its public university site in Cape Town following sustained protests. Since April 2015, the empty plinth of Cecil John Rhodes has become a site of re-imagination – from graffiti interventions to performance and installation art. While the plinth continually morphs in symbolism and significance, its ousted artwork waits at an undisclosed location for its fate to be decided. This interregnum represents a liminal condition that theorists call ‘third space’, extended in this research towards a fourth dimension of performativity. The physical disappearance of the artwork has triggered a second life, its apogee a national protest movement with global resonance. Rhodes Must Fall and Fees Must Fall are student-led calls for university decolonisation and free education arguably best understood as provocation around systemic issues in society. As this deeper work ensues amid fractious contestations, the artwork's re-animation of the public sphere is clear. Its leftover plinth is political, making visible other kinds of structural voids. It is also poetic: a zombie monument demonstrating through its reinventions public space as common space – contested, negotiated and performed in the daily creation of city futures.

The increasing involvement of the private sector in the design and management of urban public space has prompted some critical scholars to predict the ‘end of public space’. This study reassesses the implications of private sector involvement through a comparative analysis of British and Dutch urban spaces, based on a threefold critique of the existing literature on the privatization of public space. The analysis is governed by a new model of pseudo-public space that consists of four dimensions of ‘publicness’: ownership, management, accessibility and inclusiveness (OMAI). The findings suggest that, while there are significant differences between the British and the Dutch cases, neither context supports the notion of a possible ‘end of public space’ in any literal sense.
