DOES CRIME JUST MOVE AROUND THE CORNER? A CONTROLLED STUDY OF SPATIAL DISPLACEMENT AND DIFFUSION OF CRIME CONTROL BENEFITS*

Recent studies point to the potential theoretical and practical benefits of focusing police resources on crime hot spots. However, many scholars have noted that such approaches risk displacing crime or disorder to other places where programs are not in place. Although much attention has been paid to the idea of displacement, methodological problems associated with measuring it have often been overlooked. We try to fill these gaps in measurement and understanding of displacement and the related phenomenon of diffusion of crime control benefits. Our main focus is on immediate spatial displacement or diffusion of crime to areas near the targeted sites of an intervention. Do focused crime prevention efforts at places simply result in a movement of offenders to areas nearby targeted sites—“do they simply move crime around the corner”? Or, conversely, will a crime prevention effort focusing on specific places lead to improvement in areas nearby—what has come to be termed a diffusion of crime control benefits? Our data are drawn from a controlled study of displacement and diffusion in Jersey City, New Jersey. Two sites with substantial street‐level crime and disorder were targeted and carefully monitored during an experimental period. Two neighboring areas were selected as “catchment areas” from which to assess immediate spatial displacement or diffusion. Intensive police interventions were applied to each target site but not to the catchment areas. More than 6,000 20‐minute social observations were conducted in the target and catchment areas. They were supplemented by interviews and ethnographic field observations. Our findings indicate that, at least for crime markets involving drugs and prostitution, crime does not simply move around the corner. Indeed, this study supports the position that the most likely outcome of such focused crime prevention efforts is a diffusion of crime control benefits to nearby areas.     

Toxicologic findings in the USS Iowa disaster.

The toxicologic results from the 47 victims of the explosion on the USS Iowa are presented. Good correlation between carboxyhemoglobin saturations and cause of death was found. There were no correlations between blood cyanide concentrations and causes of death. Volatile analysis suggested postmortem ethanol production rather than antemortem ethanol ingestion. No drugs except nicotine were detected in any of the victims.     

The establishment of the features of the blade of a stabbing-cutting weapon by the damages to human skin and to tricot clothing]

Presents forensic medical characteristics of the specific features of stabbed and cut injuries of human skin and jersey. Suggests a complex of signs that will help determine some structural parameters of a knife blade and the conditions of its interaction with the injured site of human body.     

Impact of tropical conditions on thin layer chromatography in analytical toxicology: high temperatures and moderate humidities.

The impact of high temperatures (24 to 39 degrees C) and low to moderately high humidities (20 to 70%) on the applicability of TLC systems for drug identification was studied during a 6 month climatologic cycle in Burkina Faso (West Africa). In general, the Rf values as observed on the plates were found to be substantially affected as compared with values obtained at temperate climates. Some TLC systems were more affected than others and the largest deviations of up to 30 Rf units were at low humidities. Tropical conditions also had a negative effect on the reproducibility of Rf values. However, when an Rf-correction procedure was applied, using reference mixtures of known drugs on each plate, accuracy as well as reproducibility of the resulting Rfc values were drastically improved and data thus corrected were found to be compatible with existing TLC data bases developed under moderate climatological conditions. The impact of high to extremely high humidities (70 to 100%) remains to be investigated.     

Law enforcement information sharing: A Florida case study

Many attempts have been made over the last several decades to improve communication among law enforcement agencies. This article is a case study of a “low-level” data sharing project in Florida that could serve as a national model. The Florida Law Enforcement Data Sharing Consortium is a partnership between the University of Central Florida and more than one hundred law enforcement agencies. It offers an inexpensive, yet technically advanced alternative to the proprietary data sharing model. Its distributed architecture was endorsed by the Markle Foundation, the 9/11 Commission, and the 2004 National Security Act. Civil liberties concerns raised by this and other types of data sharing projects are discussed.     

Organic impurity profiling of 3,4-methylenedioxymethamphetamine (MDMA) tablets seized in The Netherlands.

In this study, a new method was developed for the impurity profiling of illicit MDMA tablets. The extraction efficiency, linearity, repeatability and reproducibility of the method were evaluated. Eighty two MDMA tablets coming from presumed unrelated large seizures in 2004 (n >500 tablets) were analyzed by gas chromatography mass spectrometry (GC-MS) in order to assess the discrimination power of the method. The latter was found to be practical, robust, relatively easy to perform, highly discriminative and yielding good chromatography. In addition, some new impurities were detected and identified. Their chemical structures and mass spectra are reported.     

Traditions of governance: interpreting the changing role of the public sector

The role of the state is changing under the impact of, for example, globalization. The changes have been variously understood as the new public management (NPM), the hollowing–out of the state and the new governance. This special issue of Public Administration explores the changing role of the state in advanced industrial democracies. It focuses on the puzzle of why states respond differently to common trends.
This introductory article has three aims. First, we provide a brief review of the existing literature on public sector reform to show that our approach is distinctive. We argue that the existing literature does not explore the ways in which governmental traditions shape reform. Second, we outline an interpretive approach to the analysis of public sector reform built on the notions of beliefs, traditions, dilemmas and narratives. We provide brief illustrations of these ideas drawn from the individual country articles. Finally, we outline the ground covered by all the chapters but we do not summarize and compare their experiences of reform. That task is reserved for the concluding article.     

The origin and functioning of the family advocate system

This synoptic article focuses on the origin and functioning of the Office of the Family Advocate as the protector of the interests of minor children in divorce cases. Attention is paid to the general contemporary trend to specialise in judicial decision-making that developed out of an increasing need for expertise in the administration of justice. A number of arguments for and against judicial specialisation are addressed. The origin of the Office of the Family Advocate within the South African judicial system is discussed and a brief exposition of the history of divorce legislation in South Africa is given. This is followed by attention to the functioning of the Office of the Family Advocate with reference to the process followed in investigations of this office and points of criticism against the system are highlighted. The article closes with an indication of the need for research in this regard and possible focus points for future research are identified.
