EXPLORE THE RESEARCH BY KEY CONCEPTS

This paper assesses and synthesizes the cumulative results of a new “neighborhood-effects” literature that examines social processes related to problem behaviors and health-related outcomes. Our review identified over 40 relevant studies published in peer-reviewed journals from the mid-1990s to 2001, the take-off point for an increasing level of interest in neighborhood effects. Moving beyond traditional characteristics such as concentrated poverty, we evaluate the salience of social-interactional and institutional mechanisms hypothesized to account for neighborhood-level variations in a variety of phenomena (e.g., delinquency, violence, depression, high-risk behavior), especially among adolescents. We highlight neighborhood ties, social control, mutual trust, institutional resources, disorder, and routine activity patterns. We also discuss a set of thorny methodological problems that plague the study of neighborhood effects, with special attention to selection bias. We conclude with promising strategies and directions for future research, including experimental designs, taking spatial and temporal dynamics seriously, systematic observational approaches, and benchmark data on neighborhood social processes.

A significant body of research has addressed whether fixed internet use increases, decreases or supplements the ways in which people engage in residential and workplace settings, but few studies have addressed how wireless internet use in public and semi-public spaces influences social life. Ubiquitous wi-fi adds a new dimension to the debate over how the internet may influence the structure of community.Will wireless internet use facilitate greater engagement with co-located others or encourage a form of 'public privatism'? This article reports the findings of an exploratory ethnographic study of how wi-fi was used and influenced social interactions in four different settings: paid and free wi-fi cafes in Boston, MA and Seattle,WA.This study found contrasting uses for wireless internet and competing implications for community.Two types of practices, typified in the behaviors of 'true mobiles' and 'placemakers', offer divergent futures for how wireless internet use may influence social relationships.

Concerns have been expressed that Internet use may affect social participation and involvement in the local community. Internet use can be viewed as a time-consuming activity, and it may come at the expense of face-to-face activities. The time people devote to using the Internet might replace time spent on neighborly relations and community involvement. However, the use of computer-mediated communication in geographically-based communities might also increase face-to-face communication and even solve some of the problems associated with decreasing participation and involvement in the local community. The purpose of this study was to explore the relationship between membership in a geographically-based mailing list and locally based social ties. A web-based survey of subscribers to two suburban mailing lists in Israel was conducted to investigate the relationship between membership in a mailing list and neighborhood social ties, social ties in the extended community, and the movement from online to face-to-face relationships. It was found that although membership on the mailing list did not affect the extent of neighborhood interactions, it increased the number of individuals a participant knew in the community. Online relationships with members of the local community proved likely to change into face-to-face relationships. The results imply that community networking increases social involvement and participation not in the immediate neighborhood but in the extended community and serves to complement traditional channels of communication.

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.

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.

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.

The 1992 Los Angeles riot, the boycotts of Korean-owned businesses, and the 1995 firebombing of a Jewish-owned store in New York's Harlem brought concerns about race and ethnic relations in black neighborhoods to the fore. Images of conflict seared into the public consciousness that black communities are fraught with racial animosity, with immigrant merchants pitted against black customers. The merchant- customer relationship has been cited as a catalyst to such conflicts. This image of conflict, however, is inconsistent with most merchant-customer interactions and does not reflect the full range of commercial life in black communities. Most merchant- customer interactions are civil and ordinary. Civil relations prevail because merchants foster civility, abate tensions, and thwart conflict. However, under conditions of extreme inequality, small events can trigger racial anger, and the symbolic significance of nonblack-owned businesses can become a stimulus of motivations for protest that leads to boycotts and firebombings. This study is based on 75 in-depth interviews of African American, Jewish, and Korean merchants and on 75 in-depth interviews with black customers and both participant and nonparticipant observation at five research sites in New York City and Philadelphia.

Latino immigrant presence in urban neighborhoods has been linked with reduced neighborhood cohesion in social disorganization-based ethnic heterogeneity hypotheses and enhanced cohesion in immigration revitalization approaches. Using the 2000–2002 Los Angeles Family and Neighborhood Survey and the 1994–1995 Project on Human Development in Chicago Neighborhoods Community Survey, we explore the association between Latino immigrant concentration and both levels of, and agreement about, neighborhood collective efficacy. Findings from multilevel models with heteroskedastic variance indicate that Latino immigrant concentration exhibits a nonlinear association with collective efficacy. At low levels, increases in Latino immigrant concentration diminish collective efficacy, consistent with a heterogeneity hypothesis. The negative association between Latino immigrant concentration and collective efficacy declines in magnitude as immigrant concentration increases and, particularly in LA, becomes positive beyond a threshold, consistent with an immigration revitalization effect. We also find an inverse nonlinear pattern of association with the variance of collective efficacy. At low levels, increasing Latino immigrant concentration increases the variance of collective efficacy (reflecting more disagreement), but beyond a threshold, this association becomes negative (reflecting increasing agreement). This pattern is observed in both LA and Chicago. The prevalence of social interaction and reciprocated exchange within neighborhoods explains a modest proportion of the Latino immigrant concentration effect on mean levels of collective efficacy in Chicago, but does little to explain effects on the mean in LA or effects on the variance in either LA or Chicago. These findings offer insight into the complex role Latino immigrant presence plays in shaping neighborhood social climate.

To date, research into the subjective aspects of high density has focused mainly on the negative consequences of overcrowding. This study, in contrast, outlines some of the positive aspects of high density in neighborhoods, exploring the physical-spatial environment of two neighborhoods in the city of Haifa, Israel. It was found that while the relatively high residential density was similar in both neighborhoods (40 housing units per acre), this was more positively evaluated in one neighborhood as compared to the other. This can be attributed to some specific environmental and planning features. In particular, where physical planning enabled the potential advantages of high density to be realized, this was positively perceived and evaluated by local residents. Such advantages mainly comprised accessibility to a variety of services, more frequent public transportation, and access to open spaces within walking distance. Particularly advantageous were the increased opportunities for social gathering. At the same time, however, high density did not foster social relationships at the neighborhood level. The study further identified the gender and age groups that benefited most from the high density. Thus, women evaluated high density more positively than men. Young families with children and senior citizens (over 65) were also more likely to benefit, and to evaluate the high density environment more positively than other social groups.

Leisure preferences and open space needs were explored within a discrete, homogeneous ethnic community: the Chinese Americans of Chicago's Chinatown. Face-to-face interviews and focus group discussions were used to identify outdoor leisure patterns and preferences, in general, and with respect to new park development being planned for the community. Findings show that although some popular activities are no different from what might be expected for the mainstream Anglo American population, the meaning and significance of these activities have clear and unique ties to Chinese culture. Preferences for the new Chinatown park development mirror activity preferences, emphasizing facilities that enhance the natural environment for passive activities. Notable differences in activity preferences were found within the sample of respondents according to age, generational status, and other factors. Park planning considerations and future research needs are identified.

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.

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.

Singapore is a multi-racial island nation. The three main ethnic groups are Chinese, Malays, and Indians in respective descending numbers. Prior to the extensive provision of public housing, they lived in either of two forms of housing: timber houses with roofs of "atap"—a form of palm leaves, corrugated zinc plates or asbestos sheets, or rows of shophouses of more permanent materials, such as brick and mortar, and later concrete. The shophouses were found almost exclusively in the central area, while the former was found in ubiquitous semi-rural Chinese villages "kampongs"—the Malay word for village—or urban squatter.

This study assessed the factors that shaped the development of shared trust, norms, reciprocity (TNR), and social ties—important foundations of social capital—for low-income HOPE VI (Housing Opportunities for People Everywhere) residents who relocated to new communities. A longitudinal mixed-methods approach revealed the distinct but understudied role that neighborhood institutions, facilities, and public spaces play in shaping observations, encounters, and interactions with other coresidents (as well as outsiders). Multivariate analyses of survey data indicate that neighborhood facilities and public spaces, such as parks, libraries, and recreation facilities, were very strong predictors of TNR among neighbors. Indepth interviews with relocated women revealed the ways in which neighborhood structure and public spaces can shape social encounters and relations in the neighborhood. This article presents a discussion of the ways in which these important but often overlooked neighborhood attributes can structure contact with neighbors and considers implications for policies aimed at improving low-income peoples access to social capital through relocation.

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.

Recent scholarship contends that the rise of shopping malls, gated communities, and gentrification as well as citizens' withdrawal to the private realm have eroded public life in U.S. and Latin American cities. Malls' suburban location and security policies exclude the poor and restrict free speech; residents and fences in gated communities exclude outsiders; and police and businesses in downtowns and high-rent districts limit poor people's access to public areas. I expand this discussion with an analysis of the accessibility of Santiago, Chile's retail areas, the social relationships present there, and marginalized groups' informal resistance to their exclusion. The city's distinct segregation pattern, transit system, and state-licensed street markets permit greater contact between rich and poor and foster vital public spaces. I adapt Lofland's typology of fleeting, quasi-primary, and intimate secondary relations in public to examine social interactions in street markets, flea markets, and shopping malls. The distinct mix of relationships within these markets reflects the characteristics of users, varying degrees of accessibility to diverse populations, and state policies toward markets. Marginalized groups' informal resistance is pervasive in each setting. In contrast to the dominant view that public space is declining in contemporary cities, Santiago residents are not universally reclusive, antisocial, or reluctant to engage in cross-class public encounters, and the city retains vital public areas. The findings demonstrate that our understanding of public space is incomplete without an awareness of social relationships and informal resistance alongside structural constraints to the accessibility of urban locales.

We generate a number of hypotheses about face-to-face groups using the energy distribution principle: the frequency of an event is inversely related to the amount of energy expended in that event. The principle predicts that (1) the size of groups will be inversely related to the frequency of their occurrence; (2) at any group size, the composition of social positions will be less heterogeneous than chance; and, (3) as group size increases, observed compositional homogeneity will decline at a slower rate than chance. We test these hypotheses using data on more than 100,000 naturally occurring, public, face-to-face groups gathered in sampling sweeps through two communities over a three-year period. The data support the hypotheses and yield interesting differences in the strength of sex and race heterogeneity. We discuss the findings as they relate to the general energy distribution principle and to other sociological perspectives.

Public spaces constitute one of the first urban elements to be threatened in times of instability. Their efficient supply and management becomes a concern for both public authorities and individual users. This paper examines the role and objectives of social entrepreneurs in supplying temporary public spaces within an unstable setting and focuses on small group collective action. The mechanisms used to identify potential land, negotiate use-rights and promote these spaces are discussed for the case of Beirut, Lebanon, a society segregated by the effects of war and political upheaval. The case of an organic food market is used to illustrate temporary public spaces in the critical period of 2005–2007, when political instability reigned in the country and rendered conventional public spaces undesirable. The paper concludes by drawing lessons for land readjustment in crisis situations from the movement of temporary public spaces within a city while still attracting people that formerly had difficulties meeting elsewhere.

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.

In response to Wirth's (1938) image of city dwellers as isolated individuals lacking strong ties to others, urban sociologists and network analysts have closely examined personal networks. Because neighbors are vital components of such networks, we examine three theoretical perspectives offered to explain the links between statuses and neighbor networks: social integration, need, and available time. Survey evidence from 690 adults in 81 Nashville, Tennessee neighborhoods best supports a social integration interpretation—those in statuses well integrated into society in general (female, middle-aged, married, and high-SES respondents) have larger networks within their neighborhoods. Need may be the inverse of integration, for low-SES persons, though maintaining smaller networks, have more frequent and intense contact with their neighbors.

In this article I explore how an integrated approach to the anthropological study of urban space would work ethnographically. I discuss four areas of spatial/cultural analysis—historical emergence, sociopolitical and economic structuring, patterns of social use, and experiential meanings—as a means of working out of the methodological implications of broader social construction theoretical perspectives. Two plazas in San Jose, Costa Rica, furnish ethnographic illustrations of the social mediating processes of spatial practices, symbolic meaning, and social control that provide insight into the conflicts that arise as different groups and sociopolitical forces struggle to claim and define these culturally significant public spaces.

Using surveys collected from 10 major metropolitan cities across the world, this article examines the factors that affect the extent to which people feel connected to others who live in their neighborhood and feel proud and satisfied with life in their cities. The cities included in the analysis are: New York, London, Paris, Stockholm, Toronto, Milan, Berlin, Seoul, Beijing and Tokyo. We find that certain aspects of the built environment, the conditions of the public sphere, and the extent of positive social networks in the city are critically important for understanding residents’ connections to each other and to their cities. Our findings provide insights for policy makers and planners concerned with making cities viable and livable.

Garrett Hardin's 1968 essay "The Tragedy of the Commons" famously decried the vulnerability of finite communal resources to overexploitation. Yet collective accessibility to and ownership of resources need not necessarily lead to their mismanagement or abuse; rather, the practice of sharing resources can engender positive environmental, social, economic, and political impacts. Social capital, as both the source and product of relational interactions which occur within public space, constitutes one of these benefits. This paper investigates the relationship between temporary communal spaces and social capital through a case study of the Commons project in Christchurch, New Zealand. Generated by both the space itself and the interactions that occur within it, the social capital created in and through the Commons has become a powerful symbol of recovery in a city recovering from disaster. Instead of the tragedy of the commons, therefore, this paper presents the story of the Commons of the tragedy and explores the ways in which social capital has been fostered in and through this space.

Postmodernity and economic globalization incite countries, regions, and cities to compete for investments, consumers, and resources. In aspiring for a new position in this global market, cities utilize new urban practices that lead them to rediscover and reinvent identities and traditions. In Rio de Janeiro, the mythical dimension of the South Zone is inseparably incorporated to its identity. In evaluating the history of the imagery linked to the beaches and the projects for the waterfront, one may observe a social construction of a reality that is marked by a continuous redesigning of symbols but also by a discontinuity in the history of urban interventions. Although tourism and marketing continually praise the waterfront as a fundamental factor in the image of the city, a continuous public management process never really existed. The city managers must understand the beaches, the waterfront, and development along the shoreline as important resources in a continuous process of social construction of a reality that should not only address their images as commodities but should treat them as inseparable from the city's daily public and social lives.

In India, there are religious practices intersecting with the process of urbanization at various levels. This paper looks at the practice of tree worship which continues to be a part of everyday life here. Specifically, it looks at how the Peepul tree (Ficus Religiosa) shrine with its serpent stones and the raised platform around it (katte) contributes to the territorial production of urban space in the city of Bangalore. Based on a study of 10 kattes in the city, it finds that these urban spaces belong either to a process of territorialization by the local community or its deterritorialization by the government. The paper builds a theoretical argument for how the katte as a ‘human activity node’ contributes to an ‘urban web’ which is categorized here as the physical layer. It finds that the Peepul tree could enable a ‘network of relations’, termed as the social layer. It suggests that the information fields generated within these layers influences collective memory of the people. Finally, the paper argues that the two layers acting together can help formulate an urban design model that can minimize deterritorialization.

Recent years have seen a resurgence of interest in the relation between networks and spatial context. This review examines critically a selection of the literature on how physical space affects the formation of social ties. Different aspects of this question have been a feature in network analysis, neighborhood research, geography, organizational science, architecture and design, and urban planning. Focusing primarily on work at the meso- and microlevels of analysis, we pay special attention to studies examining spatial processes in neighborhood and organizational contexts. We argue that spatial context plays a role in the formation of social ties through at least three mechanisms, spatial propinquity, spatial composition, and spatial configuration; that fully capturing the role of spatial context will require multiple disciplinary perspectives and both qualitative and quantitative research; and that both methodological and conceptual questions central to the role of space in networks remain to be answered. We conclude by identifying major challenges in this work and proposing areas for future research.

The social integration of a city depends on the extent to which people from different neighborhoods have the opportunity to interact with one another, but most prior work has not developed formal ways of conceptualizing and measuring this kind of connectedness. In this article, we develop original, network-based measures of what we call “structural connectedness” based on the everyday travel of people across neighborhoods. Our principal index captures the extent to which residents in each neighborhood of a city travel to all other neighborhoods in equal proportion. Our secondary index captures the extent to which travels within a city are concentrated in a handful of receiving neighborhoods. We illustrate the value of our indices for the 50 largest American cities based on hundreds of millions of geotagged tweets over 18 months. We uncover important features of major American cities, including the extent to which their connectedness depends on a few neighborhood hubs, and the fact that in several cities, contact between some neighborhoods is all but nonexistent. We also show that cities with greater population densities, more cosmopolitanism, and less racial segregation have higher levels of structural connectedness. Our indices can be applied to data at any spatial scale, and our measures pave the way for more powerful and precise analyses of structural connectedness and its effects across a broad array of social phenomena.

Throughout recent decades, socially-mixed neighborhoods have become a key element of urban policy and debate. This paper argues, with Amsterdam as an empirical case, that the design, layout and everyday use of social space—including public and private space—is of key importance in understanding the experiences and perspectives of social- mix policies amongst ‘urban practitioners’, such as planners, architects and management personnel. While the promotion of ‘liveability’, through the management of social problems, is often highlighted as a key element of social-mix policies, the findings presented indicate the degree to which the mixing of different groups according to ethnicity, race and social class presents a number of new challenges for liveability and management within both public and private space. Furthermore, it is argued that these challenges play a significant role in dictating the scale at which social mixing takes place, from the urban block to the street and at the neighbourhood level. It is concluded that a greater amount of attention is needed to such factors in understanding the dynamics of social interaction in public and private communal space when seeking to understand the everyday realities of socially- mixed neighborhoods.

The paper examines four case studies of neighborhood parks in socially and ethnically diverse communities of Los Angeles in order to explore similarities and differences of their uses and assigned meanings. More specifically, the study utilizes structured field observations and surveys of users in order to examine sociocultural patterns of park use, the relevance of past models of park design, and the level of fit between current park form and contemporary user needs.

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.

This study investigates the degree to which community can be found in Dutch neighbourhoods and attempts to explain why there is more community in some neighbourhoods than in others. We apply a perspective on community which assumes that people create communities with the expectation to realize some important well-being goals. Conditions that account for the creation of a local community are specified, i.e. the opportunity, ease, and motivation to do so. These conditions are realized when (i) neighbourhoods have more meeting places; (ii) neighbours are, given their resources and interests, motivated to invest in local relationships; (iii) neighbours have few relations outside of the neighbourhood, and (iv) neighbours are mutually interdependent. Data from the Survey of Social Networks of the Dutch on 1,007 respondents in 168 neighbourhoods are used. Results show that there is a sizeable amount of community in Dutch neighbourhoods and that all the four conditions contribute to the explanation, while interdependencies among neighbours have the strongest impact on the creation of community.
