This study examines a crucial question: What kind of effect do interdiction and other drug enforcement activities have on drug smuggling? Do they actually deter smuggling, or is their effect more one of disruption and displacement?...  相似文献

Despite their rich theoretical and practical importance, criminologists have paid scant attention to the patterns of crime and the responses to crime during exceptional events. Throughout the world large-scale political, social, economic, cultural, and sporting events have become commonplace. Natural disasters such as blackouts, hurricanes, tornadoes, and tsunamis present similar opportunities. Such events often tax the capacities of jurisdictions to provide safety and security in response to the exceptional event, as well as to meet the “routine” public safety needs. This article examines “routine” crime as measured by calls for police service, official crime reports, and police arrests in Salt Lake City before, during, and after the 2002 Olympic Games. The analyses suggest that while a rather benign demographic among attendees and the presence of large numbers of social control agents might have been expected to decrease calls for police service for minor crime, it actually increased in Salt Lake during this period. The implications of these findings are considered for theories of routine activities, as well as systems capacity.  相似文献

Euroscepticism is associated with a new cleavage between the ‘losers’ and the ‘winners’ of globalisation. Current research also indicates that right-wing extremist, racist, and anti-democratic attitudes are more prevalent in lower status groups, particularly those struggling with societal change. These findings are combined with a unique data set covering both topics and thus add to the growing literature on Euroscepticism while also exploring the divide between the ‘losers’ and ‘winners’ of modernisation processes. The article introduces categories of occupational status groups, namely the ‘engaged’, the ‘skilled workers’, and the ‘legworkers’, which represent different levels of involvement in modernisation processes. It explores the differences in attitudes between these groups and how those differences correlate with citizens' professional status. It is concluded that perceived subjective alienation, which manifests in racist and anti-democratic attitudes, best explains EU-scepticism.  相似文献

National Institute of Standards and Technology SRM 2372 human DNA quantitation standard has been produced to support the need for a human-specific DNA quantitation standard in forensic casework and calibration of new quantitative polymerase chain reaction (qPCR) assays. The conventional DNA concentration has been assigned with one of the U.S. National Reference UV/Visible Spectrophotometers, assuming an absorbance of 1.0 at 260 nm equals 50 ng/μL of double stranded DNA. In addition, an interlaboratory study has been conducted, to verify that the SRM 2372 materials perform well in currently used DNA quantitation assays by the forensic DNA community. Each unit of SRM 2372 consists of three well-characterized DNA extracts. Component A is a single-source human male material derived from blood. Component B is a multiple-source human female material derived from blood. Component C was purchased as a purified unsheared genomic human DNA (Sigma-Aldrich Co., St. Louis, MO) obtained as a lyophilized human genomic extract and has both male and female donors. SRM 2372 is intended to enable the comparison of DNA concentration measurements across time and place. Manufacturers can use SRM 2372 to validate the values assigned to their own reference materials. Individual forensic laboratories can use SRM 2372 to validate DNA quantitation methods and to verify the assigned concentration of in-house or commercial DNA calibration standards.  相似文献

As of 2014, 37 states have passed mandates requiring many private health insurance policies to cover diagnostic and treatment services for autism spectrum disorders (ASDs). We explore whether ASD mandates are associated with out‐of‐pocket costs, financial burden, and cost or insurance‐related problems with access to treatment among privately insured children with special health care needs (CSHCNs). We use difference‐in‐difference and difference‐in‐difference‐in‐difference approaches, comparing pre–post mandate changes in outcomes among CSHCN who have ASD versus CSHCN other than ASD. Data come from the 2005 to 2006 and the 2009 to 2010 waves of the National Survey of CSHCN. Based on the model used, our findings show no statistically significant association between state ASD mandates and caregivers’ reports about financial burden, access to care, and unmet need for services. However, we do find some evidence that ASD mandates may have beneficial effects in states in which greater percentages of privately insured individuals are subject to the mandates. We caution that we do not study the characteristics of ASD mandates in detail, and most ASD mandates have gone into effect very recently during our study period.  相似文献

This study examines the relationship between indicators of environmental control and criminal victimization rates in twenty-six large American central cities. Using a typology of criminal victimization that classifies crimes as property crimes with contact, property crimes without contact, and nonproperty assaultive crimes, it is found that both the number of police per capita and population density are negatively related to property crimes without contact and nonproperty assaultive crimes. However, the number of police per capita (controlling for population density) is not related to property crimes with contact, while population density (controlling for number of police per capita) is positively related to these crimes. Possible explanations for these patterns of relationships are discussed.  相似文献

This paper compares the Uniform Crime Reports (UCRs) to the results of the National Crime Survey (NCS). Six Part I offenses are used to form the basis for comparison across twenty-six large American cities. The two data sources are conceptually comparable. Empirically, the NCS reveals significantly higher rates for all offenses but auto theft. The two sources are compatible in that the UCR revealed the same distributional pattern as the NCS. Thus it was concluded that the UCR provides an accurate indicator of the relative occurrence of criminal acts.  相似文献

This analysis focuses on the operation of a juvenile diversion program in a large metropolitan area. In particular, the impact of the program on referrals made by the police to the juvenile court is examined. Consistent with most studies of diversion, a significant amount of net widening was found to occur following the introduction of the program. A time-series design using a four-year-preprogram and four-year-program period was employed to examine the trends in processing over time. Referrals for all categories of offenses rose significantly during the program years. The implications of these results are discussed in light of both police commitment to the goals of diversion and the legal safeguards in juvenile processing.  相似文献
