While prior research has shown that the probability of detection plays a role in the decision-making of many offenders, much less is known on offenders’ relative success in avoiding arrest. In this study, we draw from detailed criminal career data on 172 offenders involved in lucrative criminal activities to examine the role of criminal competence in the probability of being arrested in a given month. We examine a particular aspect of competence, criminal efficiency, which is defined as the ability to earn a relatively large amount of money for each crime committed. Our research design allows us to disentangle the effect of criminal efficiency as a static trait of offenders from the dynamic variations in efficiency that offenders experience over time. Results show that efficiency is a strong, negative predictor of arrest, both at the static and dynamic levels.  相似文献

Data from the International Social Survey Programme that includes individual respondents from 34 countries surveyed at four different times show that populations of countries with more actual income inequality also tolerate more income inequality, even after controlling for numerous individual- and country-level variables. Comparisons over time show that actual income inequality predicts later tolerance for income inequality, within 3–4 years, but earlier tolerance for income inequality does not predict later actual income inequality. These analyses therefore indicate that people adapt how much income inequality they tolerate to actual inequality. They contribute to a long-standing theoretical and empirical discussion about whether material structures influence or result from social norms.  相似文献

Individuals experiencing non-suicidal self-injurious (NSSI) thoughts only are greatly overlooked by current research. This investigation aimed at determining how three groups of university students differed in their reported quality of childhood relationships with parents, and histories of physical and sexual abuses. These groups included students experiencing only NSSI thoughts (n = 126), students engaging in NSSI actions (n = 90), and students exhibiting neither (n = 1,080). Results showed that individuals experiencing NSSI thoughts only, and those engaging in NSSI actions reported poorer relationships with parents and more physical abuse than the No NSSI group; however, NSSI thoughts and NSSI action groups had similar outcomes to one another for most variables. These findings suggest that individuals experiencing only NSSI thoughts share similar negative childhood environments associated with engagement in NSSI action and that they should be included in future research, particularly investigations aimed at identifying protective factors that could prevent them from engaging in NSSI.  相似文献

The ‘modernization’ of British public services seeks to broaden public sector governance networks, bringing the views of third sector organizations, the public and service users (among others) to the design, management and delivery of welfare. Building on previous analyses of the contradictions generated by these roles, this paper draws on longitudinal qualitative research to enunciate the challenges faced by one third-sector organization in facilitating service user influence in a UK National Health Service (NHS) pilot programme, alongside other roles in tension with this advocacy function. The analysis highlights limits in the extent to which lateral governance networks pluralize stakeholder involvement. The ‘framing’ of governance may mean that traditional concerns outweigh the views of new stakeholders such as the third sector and service users. Rather than prioritizing wider stakeholders' views in the design and delivery of public services, placing third sector organizations at the centre of governance networks may do more to co-opt these organizations in reproducing predominant priorities.  相似文献

Purpose

To investigate the importance of immediate spatial neighbors when investigating local crime patterns.

Methods

Local indicators of spatial association are used to identify local crime clusters. The classification scheme of these local crime clusters is then modeled in a multinomial logistic regression.

Results

The results show that immediate spatial neighbors are important for understanding local crime patterns. Though (positive) spatial autocorrelation has long been known to be present with crime data, this analysis suggests that negative spatial autocorrelation (if present) has a significantly different implication. Generally speaking, when predicting a local crime cluster type, the immediate spatial neighbors are more important for correct prediction. As such, a low local crime area that is surrounded by high crime areas presents itself as a high crime area in the regression results.

Conclusions

Therefore, efforts to understand the criminal nature of an area must not consider that area in isolation.  相似文献

After they stop drivers for exceeding the speed limit, police often have the discretion to alter the penalty. We investigated the degree to which extra-legal factors (apologies and other verbal responses), in addition to speed over the limit, predict ticket costs for speeding. Surveys of speeders were conducted in the U.S. and Canada. The data suggest that what people say to police matters. Participants who reported statements of remorse, e.g., “I’m sorry,” received lower fines for speeding. The relation of speeders’ responses to ticket costs is discussed from legal and psychological perspectives.  相似文献

Suicide by asphyxiation using helium is the most widely-promoted method of "self-deliverance" by right-to-die advocates. However, little is known about persons committing such suicides or the circumstances and manner in which they are completed. Prior reports of suicides by asphyxiation involving helium were reviewed and deaths determined by the North Carolina Office of the Chief Medical Examiner to be helium-associated asphyxial suicides occurring between January 1, 2000 and December 31, 2008 were included in a new case series examined in this article. The 10 asphyxial suicides involving helium identified in North Carolina tended to occur almost exclusively in non-Hispanic, white men who were relatively young (M age = 41.1 T 11.6). In 6 of 10 cases, decedents suffered from significant psychiatric dysfunction; in 3 of these 6 cases, psychiatric disorders were present comorbidly with substance abuse. In none of these cases were decedents suffering from terminal illness. Most persons committing suicide with helium were free of terminal illness but suffered from psychiatric and/or substance use disorders.  相似文献

We investigated agency directors' perspectives about how service goals should be prioritized for domestic violence and sexual assault service subtypes, including crisis, legal advocacy, medical advocacy, counseling, support group, and shelter services. A sample of 97 (94% response rate) North Carolina domestic violence and/or sexual assault agency directors completed a survey asking participants to rank the importance of service goals. Overall, participants considered emotional support provision to be a critical service goal priority across all service types. Social support and self-care service strategies were deemed less important. However, prioritization of other service goals varied depending on the service type. Statistically significant differences on service goal prioritization based on key agency characteristics were also examined, and agency characteristics were found to relate to differences in service goal prioritization.  相似文献

While a link is often made between the economy and crime levels, the evidence suggests that characteristics of an adverse economic climate can lead to either an increase or a decrease in crime. In this paper the impact of the recession on fraud is examined. This work is based on work undertaken by the author with fraud managers (via three group discussions), and interviews with sixteen fraudsters in prison. The findings underline the need for caution in making a link between increased levels of fraud and an adverse economic climate. More research is needed in this area to examine what types of offences, or what characteristics of them are most likely to be affected by poor economic conditions.  相似文献
