This study systematically examines the physical context of crime on urban residential blocks. A conceptual framework for understanding the relationship of the objective permanent (defensible space) and transient (territorial markers and incivilities) physical environment and the subjective environment to crime is presented. Forty-eight blocks were selected from three working-class urban neighborhoods. Data were obtained from four sources: a telephone survey of 1081 randomly sampled residents, a 15-month follow-up survey (n = 471), block-level police records of 1190 crime complaints, and the Block Booster Environmental Inventory--a new procedure for objectively measuring physical signs of disorder, territoriality and the built environment of 576 homes on all 48 blocks. Five different indicators of block crime were used: perceived crime and delinquency, reported serious and 'quality-of-life' crimes, and surveyed victimization rate. All data were aggregated to the block level. Although the various measures of crime were not consistently intercorrelated, objective environmental items correlated more strongly and consistently with the crime indicators than did the subjective environment, even after controlling for the demographic profile of the block. Defensible space features of the built environment, demographics and, to a lesser extent, the transient environment (disorder and territoriality) contributed significant variance to a series of regression equations explaining up to 60% of the variance in block crime. Implications for environmental criminology and for community policing and crime prevention are discussed.
Cellphones provide a unique opportunity to examine how new media both reflect and affect the social world. This study suggests that people map their understanding of common social rules and dilemmas onto new technologies. Over time, these interactions create and reflect a new social landscape. Based upon a year-long observational field study and in-depth interviews, this article examines cellphone usage from two main perspectives: how social norms of interaction in public spaces change and remain the same; and how cellphones become markers for social relations and reflect tacit pre-existing power relations. Informed by Goffman's concept of cross talk and Hopper's caller hegemony, the article analyzes the modifications, innovations and violations of cellphone usage on tacit codes of social interactions.
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.
Defensible space (DS) theory proposes that the built environment can promote neighborhood safety and community by encouraging residents’ appropriation of near-home space. This article examined the relationship between three differ- ent forms of resident appropriation and residents’ experiences of neighborhood safety and community. Results from a survey of 91 public housing residents living in moderately defensible spaces suggested that residents who defended near-home space through territorial appropriation experienced the neighborhood as a safer, more cohesive community than did residents who did not appropriate space in this way. Residents who spent more time outside experienced the neighborhood as a safer place; however, casual social interaction in near-home space was not consistently related to outcomes. While no causal information is available from the correlational data presented here, this work takes an important step of providing empirical evidence of a systematic link between certain aspects of resident appropriation and positive outcomes. Implications for DS theory and for public housing policy are discussed.

Uses and perceptions of nine nearby, easily-accessible outdoor areas were studied by interviewing 89 residents of a multiple-family housing development. Judgments of perceived sizes, size adequacy, use frequencies, preferences, and perceived importance were elicited, along with descriptions of personal uses. The findings reveal consistent differences between three general types of areas which serve distinct functions. The yards serve territorial needs, the common areas and public athletic fields afford recreational opportunities, and a nearby wooded area with a pond provides a highly preferred setting for a variety of nature-related pursuits. Although most ratings varied across the different types, ratings of perceived importance were high for each. The findings of this study clarify the relationships among physical size, use patterns and preferences for different areas. They also illustrate the diverse affordances of different urban nature areas, and emphasize the important role that nature contacts play in the everyday lives of urban residents.
There are two purposes to the present study. Our methodological purpose is to develop and test a procedure and instrument for assessing crime- and fear-related features of the urban residential environment. We examine three classes of cues: symbols of social and physical disorder, territorial functioning, and architectural 'defensible space' features. Past research examining the physical environment correlates of fear of crime has relied almost exclusively on subjective perceptions of the environment rather than on independent and objective measures thereof. Our theoretical purpose is to test the 'disorder' thesis of Skogan, and Wilson and Kelling, that actual physical incivilities erode resident's confidence in their neighborhood and lead them to infer that serious local problems, unrelated to the physical environment, are serious. We conducted environmental assessments and resident interviews (n = 412) on 50 blocks in 50 Baltimore neighborhoods. The assessments demonstrated high levels of inter-rater reliability and concurrent validity, controlling for social class. Regression analyses showed that physical incivilities were independently linked to perceptions of social and crime-related problems. The results show that reliable and valid assessment of crime- and fear-related environmental features can be conducted. They also support the central kernel of the Wilson and Kelling, and Skogan thesis, that the actual presence of disorder-related cues engender perceptions of social and crime problems.

In the networked information and knowledge-based economy and society, the notions of ‘open’ and ‘openness’ are used in a variety of contexts; open source, open access, open economy, open government, open innovation – just to name a few. This paper aims at discussing openness and developing a taxonomy that may be used to analyse the concept of openness. Are there different qualities of openness? How are these qualities interrelated? What analytical tools may be used to understand openness? In this paper four qualities of openness recurrent in literature and debate are explored: accessibility, transparency, participation and sharing. To further analyse openness new institutional theory as interpreted by Williamson (2000) is used, encompassing four different institutional levels; cultural embeddedness, institutional environment, governance structure and resource allocations. At what institutional levels is openness supported and/or constrained? Accessibility as a quality of openness seems to have a particularly strong relation to the other qualities of openness, whereas the notions of sharing and collaborative economics seem to be the most complex and contested quality of openness in the knowledge-based economy. This research contributes to academia, policy and governance, as handling of challenges with regard to openness vs. closure in different contexts, territorial, institutional and/or organizational, demand not only a better understanding of the concept, but also tools for analysis.
Defensible space is a model for residential environments which inhibits crime by creating the physical expression of a social fabric that defends itself. All the different elements which combine to make a defensible space have a common goal—an environment in which latent territoriality and sense of community in the inhabitants can be translated into responsibility for ensuring a safe, productive, and well-maintained living space. The potential criminal perceives such a space as controlled by its residents, leaving him an intruder easily recognized and dealt with. On the one hand this is target hardening—the traditional aim of security design as provided by locksmiths. But it must also be seen in another light. In middle-class neighborhoods, the responsibility for maintaining security has largely been relegated to the police. Upper-income neighborhoods—particularly those including high-rise apartment buildings—have supplemented police with doormen, a luxury not possible in other neighborhoods. There is serious self-deception in this posture. When people begin to protect themselves as individuals and not as a community, the battle against crime is effectively lost. The indifferent crowd witnessing a violent crime is by now an American cliché. The move of middle- and upper-class population into protective high-rises and other structures of isolation—as well guarded and as carefully differentiated from the surrounding human landscape as a military post—is just as clearly a retreat into indifference. The form of buildings and their arrangement can either discourage or encourage people to take an active part in policing while they go about their daily business. “Policing” is not intended to evoke a paranoid vision but refers to the oldest concept in the Western political tradition: the responsibility of each citizen to ensure the functioning of the polis.
“Defensible space” is a surrogate term for the range of mechanisms—real and symbolic barriers, strongly defined areas of influence, and improved opportunities for surveillance—that combine to bring an environment under the control of its residents. A defensible space is a living residential environment which can be employed by inhabitants for the enhancement of their lives, while providing security for their families, neighbors, and friends. The public areas of a multi-family residential environment devoid of defensible space can make the act of going from street to apartment equivalent to running the gauntlet. The fear and uncertainty generated by living in such an environment can slowly eat away and eventually destroy the security and sanctity of the apartment unit itself. On the other hand, by grouping dwelling units to reinforce associations of mutual benefit; by delineating paths of movement; by defining areas of activity for particular users through their juxtaposition with internal living areas; and by providing for natural opportunities for visual surveillance, architects can create a clear understanding of the function of a space, and who its users are and ought to be. This, in turn, can lead residents of all income levels to adopt extremely potent territorial attitudes and policing measures, which act as strong deterrents to potential criminals.
