ECOLOGICAL NETWORKS AND URBAN CRIME: THE STRUCTURE OF SHARED ROUTINE ACTIVITY LOCATIONS AND NEIGHBORHOOD‐LEVEL INFORMAL CONTROL CAPACITY 下载免费PDF全文
By drawing on the work of Jacobs (1961), we hypothesize that public contact among neighborhood residents while engaged in day‐to‐day routines, captured by the aggregate network structure of shared local exposure, is consequential for crime. Neighborhoods in which residents come into contact more extensively in the course of conventional routines will exhibit higher levels of public familiarity, trust, and collective efficacy with implications for the informal social control of crime. We employ the concept of ecological (“eco‐”) networks—networks linking households within neighborhoods through shared activity locations—to formalize the notion of overlapping routines. By using microsimulations of household travel patterns to construct census tract‐level eco‐networks for Columbus, OH, we examine the hypothesis that eco‐network intensity (the probability that households tied through one location in a neighborhood eco‐network will also be tied through another visited location) is negatively associated with tract‐level crime rates (N = 192). Fitted spatial autoregressive models offer evidence that neighborhoods with higher intensity eco‐networks exhibit lower levels of violent and property crime. In contrast, a higher prevalence of nonresident visitors to a given tract is positively associated with property crime. The results of these analyses hold the potential to enrich insight into the ecological processes that shape variation in neighborhood crime. 相似文献

An ongoing debate among criminologists concerns the merits of studying different dimensions of offending, such as initiation, frequency, and duration. One critical point of contention is whether separate models are necessary to explain different aspects of offending. The current study uses empirical data to assess whether different models are required to explain initiation and continuation of delinquent behavior. Using the first four waves of the National Youth Survey, we focus on the predictive ability of variables central to social control, labelling, differential association, and urbanism perspectives. We find many similarities and some differences between models for initiation and continuation of delinquency. We discuss the relevance of these results for developing a more comprehensive understanding of criminal behavior. 相似文献

Although Jemaah Islamiyah (JI) is a pan-Southeast Asia jihadi network, it has been able to headquarter itself in Indonesia, where it has also been able to find the lion's share of its recruits. This article finds that there is little support for hardline Islamic political movements, or even violent jihadi groups, from the wider population. Yet at the same time the public is skeptical about the existence of an international terrorist problem. Not only is there general denial amongst the Indonesian population but Indonesia's political leaders have had to tread carefully on the issue. Indonesia has had a degree of success in denting the JI network but confronting terrorism on the whole is fraught with political difficultiesnotably the impression that the war on terrorism might be a plot to weaken the Islamic world. 相似文献

Government departments are central organizations in the development of public policy. Yet there is very little literature on the political role of departments, their internal relationships and their relationships with other departments and other government actors and institutions. This article reviews the extant literature on government departments. It argues that much of the existing research has either focused on the role of the Prime Minister or it has been institutional and static, providing an analysis of the administration and organization of departments rather than political interactions. The article therefore provides an alternative research agenda which stresses the need to examine the relationships and networks that exist within and between departments and how departments react to events and interests in the outside world. 相似文献

This paper examines issues in using self-reports of involvement in violent acts to measure a latent construct (propensity toward violence). Three issues are addressed. First, the meaning of latent variables and the factor-analytic approach to modeling latent constructs are discussed. Second, the comparability of self-report violence measures across race and sex groups is assessed. Third, the consequences are discussed of estimating factor analytic models on pooled samples of data where the measurement component of the model does not apply equally for different subsets of the sample. 相似文献
