Objectives

This paper investigates the impact of Field Court Attendance Notices (FCANs) on rates of property crime in New South Wales (NSW), Australia. FCANs are used for relatively minor offenses, are issued ‘on the spot’, and provide an alternative to the time consuming process of arresting an alleged offender and taking them to the police station for processing. Despite their use in NSW for over 20 years, this study is the first to evaluate their impact on crime.

Methods

We use data provided by the NSW Bureau of Crime Statistics and Research, and the Australian Bureau of Statistics. We specify a general dynamic panel data model estimated via the Arellano and Bond (Rev Econ Stud 58:277–297, 1991) estimator, specifically the first-differenced twostep generalised method of moments (GMM) estimator.

Results

For property crime as a whole, in both the short- and long-run, we find no significant relationship between the use of FCANS and levels of offending. However, when offending rates are disaggregated into 11 sub-categories, we find that in the short-run an increase in the use of FCANs leads to statistically significant decreases in the rate of crime for five of the sub-categories offenses considered (break and enter dwelling; motor vehicle theft; steal from motor vehicle; steal from retail store and; steal from dwelling). The long-run results are largely consistent with the short-run results in terms of their signs and statistical significance, suggesting that the effects persist.

Conclusions

The empirical analysis presented in this paper suggests that the use of FCANs is an effective and potentially efficient policing strategy for a subset of property offenses, in that offenders can be processed at lower cost and long-run rates of certain crimes reduced.

Debate about how to best interpret the Constitution often revolves around interpretive methodologies (e.g., originalism or expansive interpretation). This article examines whether individuals’ political orientation influences the methodologies they prefer to use to interpret the Constitution. We study this proposed relationship using a survey of federal law clerks and an experimental study with college students. The survey results indicate that, compared to conservatives, liberal clerks prefer the current meaning or the most plausible appealing meaning of the constitutional text, while conservatives prefer the original meaning of the text. Liberal clerks also prefer to interpret the Constitution much more expansively. The second study manipulates the policy implications of expansive interpretation and finds this manipulation differentially affects liberals’ and conservatives’ expansiveness preferences.

Repeat burglary victimisation: a tale of two theories   总被引:2,自引:0,他引:2  
Research consistently demonstrates that crime is spatially concentrated. Considering repeat burglary, studies conducted across a variety of countries and for different periods of time demonstrate that events also cluster in time. Two theories have been proposed to explain patterns of repeat victimisation. The first suggests that repeat victimisation is the consequence of a contagion-like process. If a home has been burgled on one occasion, the risk to the home is boosted, most likely because offenders will return to exploit good opportunities further (e.g. to steal replaced items or those left behind). In contrast, the second suggests that repeat victimisation may be explained by time-stable variation in risk across homes and a chance process. Different offenders independently target attractive locations for which risk is flagged. Understanding the contribution of the two explanations is important for both criminological understanding and crime reduction. Hitherto, research concerned with repeat victimisation has adopted a top-down methodology, analysing either victimisation or offender data. In this paper, results are reported for a simple micro-simulation experiment used to examine patterns of victimisation under conditions where the contributions of both theoretical mechanisms are varied. The findings suggest that increasing the heterogeneity of target attractiveness can generate spatial concentrations of crime not dissimilar to those discussed above, but that a contagion-like process is (also) required to generate the time course of repeat victimisation. The implications of the findings are discussed.

Abstract: The relationship between postmortem concentrations of morphine and co‐detected psychoactive drugs in fatal overdoses is examined. Morphine and other drugs were detected in 161 medicolegal autopsy cases. Subsets of these morphine‐positive cases based on drug class were established, including opioids, antidepressants, ethanol, benzodiazepines, and “other.” Each subset was split into high or low concentration groups based on median drug concentrations. Morphine concentrations of the [high] and [low] groups were compared, with no significant difference in morphine concentration identified in the opioid, ethanol, or benzodiazepine subsets. The “other” drug class was too heterogeneous for statistical assessment. Morphine concentrations did show a significant direct relationship (p = 0.01) with antidepressants, namely increased concentrations of antidepressant drugs are associated with an increased concentration of morphine. This trend probably remains even after excluding cocaine‐positive cases. The unsuspected finding that postmortem concentrations of antidepressants positively correlate with morphine levels may be important in the treatment of depression in drug addicts.  相似文献

Purpose. Further to evidence of the successful application of cognitive skills programmes with offenders in HM prison service, the Enhanced Thinking Skills (ETS) training course is now delivered in various secure forensic hospitals, and its usefulness with an offender patient population merits examination. Our aim was to evaluate the impact of ETS using measures designed to capture change in key areas targeted by the course, and a more global measure of mental well‐being. Methods. Offender patients (N = 83) referred for ETS between 2001 and 2006 via a wider groupwork service within a high security hospital were administered questionnaires before and after the training course, which was minimally adjusted to meet the needs of the patient population. Attendance rates, including ‘drop‐out’ (completion of 10 or less sessions) were recorded. Demographics by subgroup (completers vs. non‐completers), and the clinical significance of any changes endorsed by participants post‐group were examined. Results. ETS completers were significantly more likely than non‐completers to endorse changes in thinking style (e.g. a reduction in post‐course scores). Significant differences were observed at both the group and individual level in the direction of less externalization of blame, a slight increase in tolerance of frustration, an increase in social conformity, and improvement in critical reasoning skills. Furthermore there was a reduction in the endorsement of aggressive solutions to social problems. Conclusions. These findings demonstrate a significant short‐term impact of the course for mentally disordered offenders with regards change in aspects of their thinking style and enhancement of their social problem solving skills. This profile lends some support to the provision of ETS within secure hospital settings.  相似文献

This cross-sectional study used an ecological framework to understand the risk and protective factors associated with use of violence among African American adolescents ages 12–17 years (N = 2,328). Using data from the 2012 National Survey on Drug Use and Health, the authors study identified different direct paths in predicting use of violence among African American adolescents. The authors then computed a multigroup analysis to determine whether significant gender differences exist in use of violence. Path analysis results suggest micro, meso, and macro factors significantly predicted violence use. The strongest predictor of use of violence among African American youth was parental conflicts. The multigroup analysis suggests that the pathways to use of violence significantly differ between African American boys and girls. Among African American boys, the strongest predictor of increased use of violence was parental conflicts; among African American girls, it was negative peer influence. Findings suggest that all 3 ecological domains and gender differences should be accounted for when developing prevention or intervention services that target use of violence among young African Americans.  相似文献

When do Americans support the government’s use of torture? We argue that perceptions of threat undermine the extent to which American public opinion serves as a bulwark against government torture. Although surveys demonstrate that a slim majority of the American public generally opposes torture, using a nationally-representative survey experiment, we show that Americans are considerably more supportive of government abuse when it is directed at individuals who they perceive as threatening: specifically, when a detainee has an Arabic name and when the alleged crime is terrorism. Given the malleability of public opinion as a potential constraint on abuse, our results underscore the importance of institutional protections of human rights.  相似文献

What motivates political parties in the legislative arena? Existing legislative bargaining models stress parties’ office and policy motivations. A particularly important question concerns how parties in coalition government agree the distribution of cabinet seats. This article adds to the portfolio allocation literature by suggesting that future electoral considerations affect bargaining over the allocation of cabinet seats in multi-party cabinets. Some parties are penalised by voters for participating in government, increasing the attractiveness of staying in opposition. This ‘cost of governing’ shifts their seat reservation price – the minimum cabinet seats demanded in return for joining the coalition. Results of a randomised survey experiment of Irish legislators support our expectation, demonstrating that political elites are sensitive to future electoral losses when contemplating the distribution of cabinet seats. This research advances our understanding of how parties’ behaviour between elections is influenced by anticipation of voters’ reactions.  相似文献

ABSTRACT

Understanding the evolution and tenacity of particular ways of envisaging economic growth and development for Africa requires a form of analytical history that examines how conceptual structures function over the longue durée. Such an approach is more than simply empirical analysis through time or a set of abstractions based on the self-understandings of historical agents. It involves the development of a hypothetical analytic structure which through its own forms of transformation eventually comes to play a role in shaping the lived world of participants, including researchers, policymakers and ordinary citizens. This article uses research from Kenya and Zambia to demonstrate how a long-running – but temporally and spatially variable – focus on agricultural productivity has shaped the character of rural life in Africa, and why it has consistently failed to deliver enlarged forms of prosperity based on quality of life and ecological well-being.  相似文献
