It is hypothesized that collective efficacy, defined as social cohesion among neighbors combined with their willingness to intervene on behalf of the common good, is linked to reduced violence. This hypothesis was tested on a 1995 survey of 8782 residents of 343 neighborhoods in Chicago, Illinois. Multilevel analyses showed that a measure of collective efficacy yields a high between-neighborhood reliability and is negatively associated with variations in violence, when individual-level characteristics, measurement error, and prior violence are controlled. Associations of concentrated disadvantage and residential instability with violence are largely mediated by collective efficacy.

Trust: The Social Virtues and the Creation of Prosperity

▪ Abstract 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 ...

ASSESSING "NEIGHBORHOOD EFFECTS": Social Processes and New Directions in Research

Communities have the potential to function effectively and adapt successfully in the aftermath of disasters. Drawing upon literatures in several disciplines, we present a theory of resilience that encompasses contemporary understandings of stress, adaptation, wellness, and resource dynamics. Community resilience is a process linking a network of adaptive capacities (resources with dynamic attributes) to adaptation after a disturbance or adversity. Community adaptation is manifest in population wellness, defined as high and non-disparate levels of mental and behavioral health, functioning, and quality of life. Community resilience emerges from four primary sets of adaptive capacities—Economic Development, Social Capital, Information and Communication, and Community Competence—that together provide a strategy for disaster readiness. To build collective resilience, communities must reduce risk and resource inequities, engage local people in mitigation, create organizational linkages, boost and protect social supports, and plan for not having a plan, which requires flexibility, decision-making skills, and trusted sources of information that function in the face of unknowns.

Community Resilience as a Metaphor, Theory, Set of Capacities, and Strategy for Disaster Readiness

Researchers suggest that fear of crime arises from community disorder, cues in the social and physical environment that are distinct from crime itself. Three ecological methods of measuring community disorder are presented: resident perceptions reported in surveys and on-site observations by trained raters, both aggregated to the street block level, and content analysis of crime- and disorder-related newspaper articles aggregated to the neighborhood level. Each method demonstrated adequate reliability and roughly equal ability to predict subsequent fear of crime among 412 residents of 50 blocks in 50 neighborhoods in Baltimore, MD. Pearson and partial correlations (controlling for sex, race, age, and victimization) were calculated at multiple levels of analysis: individual, individual deviation from block, and community (block/neighborhood). Hierarchical linear models provided comparable results under more stringent conditions. Results linking different measure of disorder with fear, and individual and aggregated demographics with fear inform theories about fear of crime and extend research on the impact of community social and physical disorder. Implications for ecological assessment of community social and physical environments are discussed.

Ecological Assessments of Community Disorder: Their Relationship to Fear of Crime and Theoretical Implications

Current work on fear of crime centers largely around three dominant theoretical models: indirect victimization, community concern, and incivilities. Previous work (Taylor and Hale 1986) confirms th...

FEAR OF CRIME IN URBAN RESIDENTIAL NEIGHBORHOODS: Implications of Between‐ and Within‐Neighborhood Sources for Current Models

Why do some blocks have more crime, or their residents have higher fear levels, than other blocks? In an effort to answer this question we proposed a model that incorporated physical defensible space features, local social ties, and territorial functioning. The model was tested using data from a multistage, stratified sample of 687 Baltimore households on 63 blocks. At each household, surveys were completed and on-site physical features were photographed and subsequently rated. Records of police activity on each block were also obtained. Our model explained significant portions of crimes of violence to persons (18%) and block fear (37%). It was also able to predict a significant amount (13%) of the variation in individual-level fear. At the block level: defensible space features dampened crime and fear but not as strongly as expected; and local social ties dampened crime and fear directly, and indirectly via an enhancement of territorial functioning. A model predicting individual fear levels, controlling ...

The physical-environment of street blocks and resident perceptions of crime and disorder: Implications for theory and measurement

Fear of crime is a significant social problem. Recognition of the serious impact that fear may have on individuals and communities has emerged among policymakers, crime prevention practitioners, as well as researchers.' As a social problem, several aspects of fear of crime are notable. By the late 1970's, fear of crime was "touching" more households than ever.2 This increase in fear to some extent paralleled the rise in crime levels during the 1970's. However, the longstanding and deep-seated nature of the fear problem is reflected in the fact that at the national level, although fear goes up as crime goes up, fear does not fall as rapidly when crime declines.3
