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

Abstract — This is the second paper of a series following a study carried out in the Brazilian Amazon region of peasant livelihoods, their current character and problems of sustainability. It analyses how different people might be affected by environmental degradation in the region by looking at their social and economic activities, the degree of dependency on wild resources, land ownership and the social relations underpinning the structure of the labour force. The study covers three districts within the ecological system of terra firme. Extractivist activities generate income and contribute considerably to food supplies throughout the year. Access to these resources is not generally tied to ownership. Environmental degradation may reduce the future availability of resources or, alternatively, attack health directly. Peasants exposure to these risks is assessed and the long-term sustainability of their livelihoods examined. Possible planning solutions to problems are presented and the more recent debate on the creation of conservation units (SNUC) in Brazil is discussed. 相似文献

Although numerous studies have found a strong relationship between offending and victimization risk, the etiology of this relationship is not well understood. Largely absent from this research is an explicit focus on neighborhood processes. However, theoretical work found in the subculture of violence literature implies that neighborhood street culture may help to account for the etiology of this phenomenon. Specifically, we should expect the magnitude of the victim–offender overlap to vary closely with neighborhood‐based violent conduct norms. This research uses waves 1 and 2 of the Family and Community Health Study (FACHS) to test the empirical validity of these notions. Our results show that the victim–offender overlap is not generalizeable across neighborhood contexts; in fact, it is especially strong in neighborhoods where the street culture predominates, whereas it is significantly weaker in areas where this culture is less prominent. These results indicate that neighborhood‐level cultural processes help to explain the victim–offender overlap, and they may cause this phenomenon to be context specific. 相似文献

Two elements have characterized the rewards for public officials in the past two decades. One is the erosion of pay and perquisites in many democratic countries. The other is a continuing variety of rewards, especially when compared to those in the private sector. Using data from a variety of OECD countries and the European Union, this article investigates alternative explanations for these two elements. The data is adjusted for purchasing power of the different currencies and then related to the relative wealth of the countries. We find that ideas, interests and institutions all have some explanatory power, but that none is sufficient by itself to explain either variety or erosion in pay across the range of countries. The policy implications of these findings, in terms of both “how” and “how much” public officials should be paid, are also examined. 相似文献

Specialization in violence is an important scientific and policy topic, and over the past several decades, many analysis techniques for studying specialization have emerged. Research in this area continues to be hampered, however, by remaining methodological problems. To overcome these problems, we propose a new method for studying specialization in violence based on an item‐response theory measurement approach that is implemented through a multilevel regression model. Our approach defines specialization as an individual level latent variable, takes into account the inherent confounds between specialization and overall level of offending, and gauges specialization relative to the population base rates of each offense. Our method also enables researchers to 1) estimate the extent and statistical significance of specialization, 2) assess the stability of specialization over time, and 3) relate specialization to explanatory variables. Using data from three studies, we found substantial levels of specialization in violence, considerable stability in specialization over time, and several significant and relatively consistent relationships of specialization to explanatory variables such as gender, parental education, and risk‐seeking. 相似文献

Relying on extensions of routine activities and social disorganization theories, we examine whether 1) neighborhood social characteristics shape opportunities for the development of unstructured socializing with peers among adolescents, 2) whether unstructured socializing leads to an increase in violent behavior within urban communities, and 3) whether neighborhood collective efficacy modifies the impact of unstructured socializing on violence. The study outlined in this article uses three waves of data from the Project on Human Development in Chicago Neighborhoods Community Survey and Longitudinal Cohort Study. Results from multilevel linear models suggest that neighborhood collective efficacy supports the development of unstructured socializing with peers. Multilevel Rasch models of violent behavior indicate that, consistent with previous research, unstructured socializing is a powerful predictor of violence. Collective efficacy exerts an independent influence on violent behavior and attenuates the effect of unstructured socializing on this outcome. 相似文献

The Crisis Negotiation Unit (CNU) method of negotiation as a response to international kidnapping disrupts criminal and terrorist operations alike. It combines crisis intervention, sound aggressive business negotiation, academic negotiation research, and hard earned experience into an aggressive effort to exploit the kidnappers. The cornerstone of this is that negotiation is not concession. The CNU method reduces the risk of harm to the victims, increases the chances of their safe release, and enhances the likelihood of a successful apprehension of the kidnappers.‐ 相似文献
